Rope Torture

Story Source:

 

I should probably introduce the background for this 
particular escapade so it makes a little more sense, 
shouldn't I? There are three players (read whatever 
meaning into that phrase that you like): myself (Mike), 
my then girlfriend and now wife (Sara), and her sister 
(Kim).

Sara and Kim have been involved with each other in a 
sexual way since they were children, a relationship 
that started off, as should be expected, because of 
exploratory curiosity. Their mom had caught them once 
not long after they'd started, oddly accepting of the 
behavior, and this had made them morbidly fearful they 
were going to be punished for it by their dad. It was 
never mentioned, and so they started again after a few 
months of nothing happening. Their sexual relationship 
has never faltered since.

Sara and I met in high school, where we were both self-
exiled oddities, floating outside the ridiculously 
idiotic and narrow-minded status quo that defines the 
student body of every high school. I was a relatively 
popular angsty artist and she was a wallflower 
bookworm. Perfect match? It's certainly turned out that 
way so far.

Sara and I started talking during our sophomore year 
after I drew a picture of her for her, and we grew a 
lot closer during the remainder of high school. Our 
junior year is when things between us starting to 
really develop a lot more depth at the same time she 
told me she and Kim were lovers, information that 
didn't quite affect me or our relationship in any way 
we had been expecting it might.

After all, there aren't a lot of guys who would find 
the thought of two women having sex a turn off, hmmm? 
Especially when one of those women happens to be his 
girlfriend. That my girlfriend's girlfriend happened to 
also be her sister didn't phase me too terribly much, 
mainly, I think, because I find both of them to be very 
enjoyable people. That and I have a thing for my step-
sister, though any possibility of anything, even 
friendship, happening with her is effectively nil, for 
an assortment of different reasons.

Christmas break of my and Sara's senior year in high 
school, Sara and Kim were invited to one of their 
cousin's to spend the winter holidays there. Kim, 
unfortunately, caught a nasty bout of the flu just 
before they were to leave, so she had to stay behind. 
She was better by the time Christmas came around, but 
couldn't very well leave and join her sister because of 
snow, so I invited her over to spend the holidays with 
me. We had a good time, though we both agreed that Sara 
needed to be there.

To celebrate New Year's, my parents had gotten a whole 
slew of various drinks, mostly soft liquor, since they 
knew me and Kim would likely also be drinking. Which we 
did, quite happily. We were merrily drunk by the time 
midnight came along, though I suspect Kim was much less 
so than I was. That or she can handle alcohol really 
well. We got to talking about sex (no surprise), then 
somehow ended up in my bed and having sex. I vaguely 
remember being curious what it would be like, knowing 
Kim's a lesbian, but beyond that, everything's rather 
blurred.

We went at each other again in the morning, much less 
drunk and enjoying it a lot more for that. My main 
surprise was how quiet Kim is compared to her sister, 
considering how much she likes to talk. Sara, by 
contrast, is quite vocal when having sex, but doesn't 
talk much unless it's something she finds exciting or 
she needs to express or explain something.

We had been worried how Sara would react about us 
having sex, but needn't have, as it turned out. She 
just laughed and kissed both of us, more annoyed that 
she'd now have to share than anything else. Kim had 
apparently raised the issue with her a time or two 
before, out of curiosity.

After high school, Sara and I got a place together, me 
starting college for art while also working in the same 
field because of a chance contact I'd made in high 
school. Sara got a job at the library and a part-time 
job at a bookstore, which let her indulge her 
omnivorous and never ending reading habit. Kim often 
stayed weekends at our place, and this particular 
episode is about one rather memorable Saturday that 
managed to overload both of them; not an easy task, 
given their hyper-active libidos.

I should note, before actually starting the telling of 
this, that there's one odd thing about Kim that Sara 
and I were already aware of: As long as she has 
something in her pussy, even if it's not moving, she 
has non-stop, multiple orgasms. If she's actually being 
fucked, they hit so close together that she's 
effectively subjected to a constant orgasm, one orgasm 
starting while the one just before it is still fading. 
I had decided to take advantage of this, thinking she 
was enough like Sara that it wouldn't matter if there 
were something in her or not.

"What say the two of you to a bit of pleasure torture 
while we're out today?" I'd asked that morning, wearing 
my evil innocent smile. Sara and I had several lengths 
of rope sitting in our room, for which purpose I'm sure 
you can guess, and I had an idea.

"What kind of torture, Mr. Man?" Kim had asked, perking 
up at my question. She hadn't started calling me that 
until she'd watched most of my Animaniacs collection.

Sara had simply grinned, which was answer enough. She 
loved being tortured, especially when it meant great 
orgasms could be had in large quantities.

"Oh, nothing elaborate." I grinned. "I'm just thinking 
a bit of simple ropework and some constant stimulation 
to your clits every time you move."

"Oooh! Ropes!" Sara enthused.

It would have been comical if she hadn't been so 
excited about it. I'd had to grab her and toss her back 
on the sofa and give her a good, long kiss to get her 
to stay put and not get the ropes herself. I ran a hand 
down her stomach and masturbated her while I kissed 
her. She tried pulling out of it as she approached 
orgasm, but I held her in the kiss, and she shuddered 
and moaned as she came. I broke the kiss as she came 
down from climax and then tweaked her now over-
sensitive clit, making her squirm.

Making her cum was the best way to momentarily curb her 
enthusiasm, but it would be back pretty quickly, I 
knew. One orgasm tended only to feed her hunger for 
more.

"Ropes?" Kim asked after I'd gotten Sara off. "How's 
that going to torture us?"

I just grinned and winked at her.

"You'll find out." I turned to Sara and shook a finger 
at her. "Stay." And then I dashed off.

The two of them were sitting together on the couch when 
I got back, thoroughly engaged in attacking the other's 
tongue with her own. Both had their legs spread, giving 
me a great view of their pussies as they masturbated 
each other. It was a great picture moment, and I 
grabbed the digital cam to do just that.

Sara plunged three fingers into Kim when she heard me 
take the first picture, and her timing amazed me, as I 
snapped another picture just at that moment. Our 
computer's wallpaper is now Sara and Kim necking and 
masturbating each other on the couch, with Kim's look 
of surprise at the sudden penetration perfectly 
captured.

It didn't take her long to recover and reciprocate, and 
she upped the pressure on Sara to do more by putting 
four fingers in her. Sara moaned and clawed at Kim's 
back, pulling her closer and attacking her sister's 
mouth even more ferociously, matching her finger for 
finger and starting to work her whole hand in. Kim 
broke the kiss and immediately moved to her sister's 
shoulder, biting hard and almost screaming. I could see 
the teeth marks even from across the room when she 
pulled back.

"Bitch," she panted at Sara, and shoved her whole hand 
into her in one sharp movement.

Sara cried out, her eyes going wide and mouth gaping 
open, a moment I unfortunately missed with the camera. 
It took her several seconds to get over her shock, at 
which point she grabbed Kim and dragged her even 
closer.

"Fucking horny slut," she hissed, catching Kim's mouth 
with hers while she slowly shoved her fist into her, 
keeping it out halfway, the widest point.

Kim tried pulling out of the kiss, but Sara held her, 
twisting her hand a few times before driving it up as 
far as she could. Kim's look was lost behind Sara's 
head, but her screaming into the kiss was more than 
enough to make up for it. She was trembling by this 
point, but I'd say it was more passion than anything 
else, since she managed to drive her own hand more into 
her sister with great enthusiasm, eliciting much 
moaning.

They continued to fist fuck each other for probably ten 
minutes, me taking pictures and hurriedly switching a 
new card into the camera when the first filled up. Sara 
was the first to break, which surprised me, given she 
had a good sized masochistic streak. She shoved Kim 
away, gasping for breath from the prolonged kiss and 
what apparently must have been a near constant string 
of orgasms, and muttered a long stream of swearing as 
she ripped Kim's hand out of her pussy. She collapsed 
back onto the sofa and would have pulled her hand from 
her sister if Kim hadn't stopped her.

Another surprise. Kim gripped her sister's arm and 
followed suit, falling back against the other arm of 
the sofa, where she lay, trembling. She gasped as Sara 
twisted her hand and tightened her grip on Sara's arm 
as she flexed and lifted her sister with her arm.

"Oh fuck!" Kim exclaimed, shuddering and going wide-
eyed. "That hurts that hurts that hurts." A long flow 
of 'fuck's and 'oh god's followed while she was stuck 
trying to figure out how to get her sister's hand out 
of her and stop the pain.

I could see why she was complaining. I could see the 
bulge Sara's hand was making in her belly as she lifted 
her. I got a picture of that, too, as I'm sure they 
would both love seeing it later, especially to get all 
hot and bothered over.

"Uncle!" Kim screamed. "I give! I give! Fuuuuuuuuuck!"

Sara smirked and dropped her arm, letting Kim collapse 
back to the sofa, and slowly withdrew her hand. She 
fell back again and lazily licked Kim's juices from her 
hand and fingers. Kim curled into a ball next to her, 
slowly massaging her pussy and lower belly.

"That was a good show for the camera," I said, smiling 
and waving it in the air beside me. "I don't suppose 
you've done that before?"

"Fisting each other?" Sara asked. "Not very often. It 
hurts like hell, and that subdues any pleasure after a 
few minutes."

"But the orgasms are fucking great," Kim added, working 
herself up into a half-sitting, half-lying position. 
"But she hasn't ever done THAT before." She winced, 
gingerly inserting a pair of fingers into herself.

"Because we need to save some energy for being 
tortured. And you were starting to hurt my hand with 
your orgasms. You fucking cum hard, bitch."

Kim laughed.

"And you weren't hurting my hand? You cum just as hard 
as I do. I thought you'd be the last to stop, since 
you're such a pain slut."

"Well, the slut part I know isn't true," I interjected, 
"but masochist, yes." I winked at Sara. "As for how 
hard the two of you cum..." I actually had to pause and 
think about that, which almost made me laugh at the 
absurdity of it. I knew full well how hard they both 
came. "I have to agree on that. You both cum pretty 
damn hard. I'm surprised the both of you haven't turned 
my dick to jelly by now."

"Oh, we would never do that." Sara grinned. "We like it 
way too much, especially when you're using it to fuck 
us good and hard."

"I agree with sis, Mr. Man. You're the best guy I've 
ever fucked."

"I'm the only man you've ever fucked, Kim," I laughed. 
I knew her relationship with her sister had turned her 
off on guys, which made me the single exception.

"True. But that's beside the point, Mr. Man. I still 
love you, especially when you're getting me off when 
you're slamming that hard cock of yours into me." She 
grinned and winked at me. "Which I think it's about 
time you used on us. We could use a couple more 
orgasms." She looked over at Sara. "Don't you agree, 
sis?"

"Definitely."

Sara sat up, keeping her legs spread and giving me a 
good view of her soaked pussy. She started to stand, 
but I motioned her back down. She pouted but did as 
told, leaning back and resting her arms on the back of 
the sofa so her breasts were thrust out. She scooted 
her ass forward and spread her legs even more, licking 
her lips as she looked at me. Kim had arced one leg 
over the back of the sofa and was slowly masturbating, 
one hand on her breasts and the other rubbing her clit.

"Mmm. That sounds like a good idea, and you're both 
making it damn hard to say no, but if we start fucking 
like bunnies now, we won't have time today to do 
anything with my torture idea."

"With ropes?" Sara leaned forward eagerly.

"With ropes," I agreed, scooping up one coil.

"Yay!" She bounced on the edge of the cushion she was 
on, clapping her hands.

I grinned at her.

"You get yourself back in your pose and I'll start."

She quickly did, scooting even further forward so her 
ass wasn't even on the sofa anymore, allowing her to 
spread her legs as far as she could get them. She 
looked at me expectantly as I stood and dropped the 
rope on the floor in front of her, then knelt.

"You need to be very turned on for this to be most 
effective." That wasn't true, but it was a good excuse 
to torture her a bit.

"More than I am now?" Sara giggled.

"Yep," I said, and then went at her pussy with my mouth 
before she could say anything more.

She gasped and moaned, clutching my hair with her hands 
and holding me where I was while I teased her with my 
tongue. I knew she loved having my tongue inside her, 
so I didn't do more than circle it around her entrance, 
sometimes barely dipping in. It was easy to tell when 
she was getting close to climax, since she started 
shaking, and I stopped every time she did, eliciting 
loud moans of protest.

I moved up to her clit after about ten minutes of 
keeping her riding the edge of climax and teased here 
there for just as long, still not letting her cum. I 
nibbled her clit while I teased with my tongue, biting 
hard and not letting up every time she started shaking, 
which always kept her right on the edge.

She tightened her grip on my hair as I pulled back once 
I had her clit nice and hard, trying to keep me in 
place and bring her off. I pulled her hands away and 
slowly licked from her asshole up to her clit, making 
her shudder as it brought her right to the edge of no 
return. She whimpered and rocked her hips, looking at 
me and pleading with her eyes. I only smiled at her, 
making her whimper even more as she tossed her head 
back in frustration.

I let her cool down for a minute so she wouldn't cum 
when I touched her, then took up the rope, doubled it 
up, and wound it around her waist. She gasped when she 
felt it and looked down at me to watch, rocking her 
hips again. I tied a knot just above where her pubic 
hair would have been if she didn't shave every day, 
then had her stand up so I could finish. I pinched her 
clit hard as I ran the doubled rope between her legs, 
making her gasp and shiver, and set one strand on 
either side of her clit.

"Don't cum," I told her, making her whimper even more.

I waited a few seconds, then increased my pressure on 
her clit and pulled hard, making her cry out and clench 
her fists as she trembled, riding the edge of climax. I 
knew the pressure pain on her clit would keep her from 
cumming while also keeping her right on the edge, but 
with as sensitive as she always was anymore, I had 
gotten in the habit of telling her not to anytime I did 
anything to her clit unless I was wanting her to cum. I 
pulled the rope tight, capturing her clit with it, and 
then tied off the ends at the small of her back after 
pulling it even tighter, making sure it dug into her 
pussy a bit painfully.

"Can I cum yet?" she asked as I stood, her breath 
ragged.

"Only if you can do so while walking," I said, smiling 
at her and lightly running a finger on her clit.

She moaned and clung to me, shaking as she fought 
against cumming from my teasing. She shoved my hand 
away after only a few seconds more, gasping through 
clenched teeth and digging her fingers into my arm.

"You're evil," she breathed, straightening and standing 
shakily.

"But you love it," I said, grinning at her.

"Oh god yes." She pulled me into a hungry kiss, rubbing 
her body against me. "What do I have to do, you 
bastard?"

"Cum while you're walking." My grin broadened and I 
winked at her. "Walk around the room. The rope'll do 
the rest."

"Oh god..."

She looked around the room, the biggest in the house, 
then back at me. I simply smiled my evil innocent smile 
and gave her a kiss, nibbling her lip, then pulled away 
and grabbed the camera again. I wanted to capture this, 
and judging by Kim's, "Oooh, pictures..." she did too.

Sara looked around the room again and then started 
walking. Her gasp was all the indication I needed to 
know the rope was doing exactly what I had been 
planning. I started taking pictures, making sure to 
stay in front of her so I could capture her 
expressions. I knew she was trying to avoid orgasm, but 
it didn't take long for her to cum, and I grinned as 
she did. She stumbled and grabbed at the wall, almost 
falling. She didn't make it very far while her orgasm 
was hitting her, but she did manage to stay on her 
feet.

She swallowed hard and managed to make it back to the 
sofa, trembling with each step as the rope matched her 
every movement and rubbed on her clit. She collapsed 
back into the spot she had been moments before and 
spread her legs, her thighs trembling as she slowly 
rocked her hips. She whimpered as she came again, 
digging her fingers at the cushion beneath her.

"Holy fuck..." Kim muttered, giggling as she reached 
over and ran her fingers over Sara's thighs, which were 
covered in her juices from just the one orgasm. She 
looked at me. "And you expect us to wear that all day?"

"Yep," I said, grinning.

Kim shivered and grinned, getting into the same 
position Sara had been in, arms across the back of the 
sofa, ass hanging off the edge, and legs spread wide. 
Her pussy, thighs, and the crack of her ass glistened 
with her juices.

"Do me! Do me! That looks like great torture!"

"You're going to kill us with orgasms, Mike," Sara 
said, clearly fighting to keep her hips still and her 
hands away from the rope to untie it. She was 
succeeding with the second but failing with the first, 
and she shook as she came again, which only made her 
rock more.

"If I am, it'd be the best way to die of anything I 
could do to you."

Sara moaned in agreement as I knelt in front of Kim, 
leaning her head back and closing her eyes, 
surrendering the fight against her body and letting her 
hips keep rocking and making the rope continue 
stimulating her clit, driving her to orgasm after 
orgasm. She spread her legs even further, making the 
rope dig into her pussy even more. She'd have marks 
later, and probably even bruises if she kept doing 
that, but I knew she would consider it a minor 
inconvenience as long as the pain felt good and gave 
her good orgasms.

I didn't need to spend as long getting Kim's clit as 
hard as I wanted it, since she'd been masturbating the 
whole time I had been working on Sara. Unlike Sara, I 
made her cum a few times, working my fingers hard, 
fast, and deep into her pussy, since I knew she didn't 
take as well as her sister did to being denied orgasm. 
She stopped me as I was laying the strands of rope 
beside her clit, and I looked at her quizzically.

"I want something in me."

"No. Just the rope for the day. You'll have plenty of 
being filled tonight."

She frowned.

"Please?"

"No."

"Let me cum a few more times right now, then."

She grabbed my slick hand and stuck my fingers back in 
her. I moved the rope out of the way and sucked her 
clit into my mouth, nibbling while I finger fucked her. 
On a whim, I shoved a finger up her ass, making her 
gasp and shudder. I knew having something up her ass 
made her cum even harder and I had to stop sawing my 
fingers into her, then pull them out after a few 
minutes because they were going numb from lack of 
circulation. She cried out as I did that and shoved a 
pair of her own fingers into her pussy.

I went off to clean my hands, mainly because they were 
now too slippery to be able to do anything with the 
rope, then finished tying it around Kim's waist and 
against her clit. With Kim, I tied a series of knots 
that would rub the length of her slit as she moved, 
since I didn't want either of them to experience quite 
the same thing.

The ropes now done, I dragged them both into the shower 
so we could clean up some before heading out for the 
day. Kim had wanted to go without panties and bra for 
the day, but I had her wear panties anyway, along with 
Sara, and had them both wear a pad, which we kept 
around only because they were more effective than 
tampons if we were playing around with remote vibrators 
or the like. I knew they were both going to be leaking 
excessively and didn't feel like cleaning the car later 
after everything had dried.

Needless to say, we found a lot of excuses to spend a 
lot of time walking. Sara quickly learned to walk a bit 
more slowly than usual so she could at least function 
somewhat normally while being so aroused and cumming so 
much.

This had the entertaining side effect of causing her 
orgasms to build up even more before they hit, so even 
though she wasn't cumming every ten minutes, she was 
still entirely incapacitated at least two or three or 
four times an hour as a much more powerful climax 
gripped her. That she had to always catch herself from 
making any noticeable sounds also drove her orgasms to 
being more powerful than normal, since she had to keep 
all that energy bottled up.

Kim, on the other hand, didn't seem to cum at all, as 
far as I or Sara noticed. She merely became 
increasingly grabby of my hands, trying to get me to 
shove them in her, or clinging onto Sara and going down 
on her. I just laughed as the lesbian antics got a lot 
of strange looks, then pulled Kim off her sister and 
led the two elsewhere.

By the time we got back to my and Sara's place at about 
eight that evening, Sara was almost entirely wiped out 
from so many intense orgasms over the course of the 
day. I stopped her from trying to take the rope off 
when we got home, and she whimpered as she leaned 
against me to keep from falling over, but she complied 
and kept her hands away from the rope.

Kim, on the other hand, attacked me with a passion, 
deftly untying the rope and ripping it off as she 
shoved me toward the bedroom, kissing me hungrily and 
jerking me off in the process. Sara followed 
unsteadily, walking slowly to avoid inducing another 
orgasm too quickly. Kim threw me on the bed and landed 
on top of me, still kissing as she tried to get 
clothing off, both mine and hers.

"You are going to fuck me," she said between hard 
kisses, "and you are going to fuck me now, and you are 
going to make me cum until I pass out. Understood?"

I pulled her shirt up and off, since she was fumbling 
too much to be able to do it, and then rolled her over, 
straddling her and pulling my own shirt off. I captured 
her hands and held them above her head to keep them 
away from my crotch so she wouldn't do anything painful 
in her enthusiasm.

That's one thing I've noticed women don't seem to 
comprehend about guys, just how much it hurts us when 
pain is inflicted in that particular location. I 
usually describe it as a combination of a really bad 
stomach flu, the sort of food poisoning that makes you 
feel like throwing up and shitting at the same time, 
diarrhea, constipation, and really bad cramps.

And then when that wears off, usually after an hour or 
more, a sharp, shooting pain that feels like a fishhook 
skewering your flesh every time pressure of any kind is 
applied, but especially when trying to sit down. That 
usually does the trick.

I leaned down and shoved my tongue into her mouth, 
which she accepted greedily, rocking her hips up 
against me. She broke the kiss pretty quickly, biting 
at my lip and trying to free her hands from my grip so 
she could roll back on top.

"Fuck me already, god damnit," she panted, spreading 
her legs and arching her hips up. I could feel her 
quivering beneath me.

"Haven't cum enough from the rope, I take it?" I smiled 
down at her.

That only inflamed her even more. She surged and almost 
managed to flip me over, but she didn't have quite the 
strength to do it. She cried out in frustration, 
squirming her legs and shaking in need even more.

"No, god damnit. I haven't fucking cum since you put 
the damn thing on. All the fucking thing did was make 
me horny as all hell, and - I - fucking - need - to - 
cum - NOW!"

This time I let her flip me over, but then used the 
momentum to continue the roll and land back on top 
again.

"Fuuuuuck meeeeee," she cried, banging her head on the 
bed.

"So you didn't cum at all from the rope, hm?" I mused, 
getting an idea.

"No! I can't unless I have something in me - like you-" 
she bucked her hips at me, "-or if Sara and I are 
screwing. Now fuck me, already! Fuck, even just a god 
damn finger would do at this point. Just let me CUM!"

"I don't know about you, Mike," Sara said, and Kim and 
I looked over at her standing beside the bed, hands 
behind her back, "but it's kind of fun seeing her 
squirm and beg like this." She grinned. "And I didn't 
know that about you, sis. I say we test it out, tie you 
up and have Mike do everything he does so well to try 
and get you off without actually fucking you or putting 
anything in you."

"Oh god no..." Kim breathed. "You fucking devil woman. 
You wouldn't."

Sara's grin widened as she brought her hands into view, 
dangling handcuffs.

"Oh fuck! No!"

Kim started squirming so much I could barely hold her, 
and I leaned down and bit hard on her shoulder. That 
stopped her.

"OW! Fucking bastard! What the hell'd you do that for?"

"To get your attention," I answered, fixing my grip on 
her arms again. "How about a deal?"

She narrowed her eyes at me, then looked over at Sara, 
who had set the handcuffs on the bedside table and 
stripped, though she'd kept the rope on. She flicked 
her eyes back to me.

"Sara only suggested what I was already thinking. Tie 
you down and try to make you cum without something in 
you or by screwing her. If you don't cum, she and I 
will fuck you senseless, and Sara will keep her rope on 
while she does it."

I smiled as Sara drew in a sharp breath. Kim was still, 
looking back and forth between her sister and me while 
she considered.

"Do I have to keep the rope on?" Sara asked, plaintive.

"Yes."

She whimpered, and even out of the corner of my eye I 
noticed her shiver. I smiled as her hands went to her 
pussy and covered it.

"Half an hour," Kim said.

"Hour and a half," Sara countered, obviously not eager 
to be overwhelmed with more orgasms so soon.

"Half an hour, devil woman."

"One hour," I said. I glanced at the clock and saw it 
was exactly nine. "Starting now. Set the alarm for ten, 
Sara." I turned back to Kim. "Keep your hands away from 
your pussy once I get up to tie you down, or I'm going 
to be evil and tape a vib to your clit for the whole 
hour on top of everything else I'm going to do."

Kim shivered and squeezed her eyes shut, frowning. I 
released her hands from mine and wrapped my arms around 
her, giving her a deep, passionate kiss for a couple 
minutes before getting up. She clutched at me as I did, 
trying to pull me back, but I pulled her hands away. I 
had to turn away to grab the cuffs and she had a hand 
on her pussy when I turned back, rubbing her clit. I 
let her continue while I shackled her other hand to the 
bed frame, then took her other and did the same. I 
pulled her skirt and panties off, then took her clit 
between my fingers and squeezed and rolled it slowly 
before I said anything.

"Guess you wanted that vib on your clit for the whole 
hour, hm?"

She gasped and shook her head frantically as Sara 
giggled. I tightened my pressure on her clit, making 
her gasp even more, and her thighs shook as she arched 
her hips.

"No, no, no, no, no, no! Please! I'm desperate enough 
already, damnit! No vibs!"

"But I did tell you to keep your hands away from your 
pussy when I got up, and you didn't do that."

She whimpered as I started pulling on her clit while I 
looked over at Sara, who had anticipated my request and 
handed me a spot vib, a roll of duct tape, and some 
more rope to tie Kim's legs with. Kim spread her legs 
even more and arched further, vainly trying to lessen 
the tension and pain I was inflicting on her clit as I 
pulled it increasingly harder while also squeezing even 
more. She moaned and gasped as I stopped to uncoil the 
ropes. I directed Sara to tease her sister's nipples, 
but to not let her cum, while I tied her legs, which 
wasn't an easy task with as much as she was squirming.

I paused for a moment and looked at a shaking Kim, the 
first time she had agreed to being tied up. I teased a 
finger up and down the length of her pussy, circling 
her clit, to which she started to rock her hips. Or at 
least as much as she was able without the leverage her 
legs would normally have given her. She was completely 
slicked with her juices, and I licked my fingers clean 
after pulling them away again.

"Sara." She stopped and looked at me, which made Kim 
swear at the sudden cessation of being touched. "Kiss 
her. Long, deep, and hard, and keep her that way for a 
bit. She needs a good gag that can respond to whatever 
she might do when she gets loud and boisterous."

I winked at her as I picked up the vib and bounced it 
back and forth between my fingers. She giggled and did 
as told, and I pulled the vib's controller over, eyeing 
Kim's pussy.

Duct tape certainly would not hold with as wet as she 
was, so I decided to do a little cleaning and a bit 
more teasing before putting the vib on. I switched the 
vib to its lowest setting and grinned as Kim moaned 
into Sara's mouth and started squirming even more. She 
tried to close her legs, but the rope stopped her, and 
I held the vib against her clit.

That made her cry out even louder, muffled by Sara's 
mouth. I moved down the bed a bit more for a more 
comfortable angle, then leaned down and started licking 
Kim's juices from her thighs. She was getting very 
vocal by now and would probably have annoyed the 
neighbors if Sara wasn't such a good gag, but she was 
at least not squirming as much, feeling my tongue. She 
was shaking instead, which increased as I drew nearer 
to her pussy. I shifted my arm and hand so I could run 
my tongue up the crack of her ass, and she started 
screaming as I rimmed her.

Smiling, I pulled back, keeping the vib in place, and 
she tried extending her legs to pull me back, the rope 
preventing her. She moaned loudly in frustration, and I 
watched her pussy twitch, more of her sweetness flowing 
out. I circled the vib a bit, then slid it slowly down 
and nestled it right at her entrance, which made her go 
completely still, her pussy spasming even more as she 
teetered right on the edge of orgasm.

I dropped the vib down to her asshole as I started 
cleaning her juices from the areas of her pussy I 
hadn't been able to get to with the vib in the way. She 
cried wantonly as I ran the vib back and forth between 
her asshole and the flowing tunnel of her cunt while I 
sucked on her clit, flicking my tongue over it as I 
nibbled.

Sara was doing a superb job of keeping her sister 
locked in a kiss, and I reached over, sticking a finger 
into her and making her gasp and rock her hips, which 
brought her to another orgasm. She sank slowly to the 
bed, lying shakily on Kim but still managing to hold 
the kiss, moaning while her orgasm trembled through 
her. I hooked my fingers and worked hard on her g-spot, 
prolonging her climax, then sat up, pulling my fingers 
from her and holding the vib against Kim's vagina 
again.

I dropped the vib, letting it rest against the base of 
Kim's ass, and Kim moaned loudly into Sara's mouth. I 
ripped a strip of duct tape from the roll, stuck it to 
the vib, and then taped it against Kim's clit, making 
her squirm and cry out even louder.

I stopped for a moment and looked at the clock. Nine 
twenty-two. Plenty of time yet.

"Time for a different use for your mouth, love."

It took Sara a few seconds to pull away from her 
sister, but she did, and Kim panted and tossed her head 
from side to side, whimpering incoherently as the vib 
tortured her clit. Sara looked at me as she kissed and 
bit down Kim's throat to her shoulders, smiling 
wickedly.

"Nipples?" she asked, moving down further and biting 
one.

"Breasts. Do whatever you like, but do nothing directly 
to her nipples, though you can get as close as you like 
to them."

"Oh god..." Kim moaned and whimpered, trying 
ineffectively to free her legs from their bindings so 
she could have more movement to express her 
frustration.

"And your hand-" I took one of Sara's hands and set it 
on Kim's pussy, "-is to tease that. Circle your fingers 
around her tunnel and her asshole, but DO NOT put them 
in. Understood?"

"Fucking bastard..." Kim banged her head against the 
bed, straining against the handcuffs, her breathing 
getting even more ragged as Sara's fingers went to 
work. "Fucking let me cum, god damnit."

I moved up and kissed her hungrily, and she returned it 
even more aggressively. It felt like she was trying to 
suck my tongue out of my head, and I bit her lip, 
pulling back and grinning at her as she followed, 
trying to catch me in a kiss again.

"Not yet."

She swore and fell back, shaking and moaning as Sara 
teased her. I wandered over to the closet and pulled 
out some more vibs to use toward the end of the hour, 
then straddled Kim's head after propping her up with 
some pillows. She eyed me, half-glazed, and eagerly 
opened her mouth to suck my penis in as I pressed 
forward. She sucked just as hard as she had with the 
kiss, doing everything she could with her tongue, and I 
had to keep feeding her my cock so it wouldn't hurt so 
much. She stopped sucking so hard when I hit the back 
of her throat and kept pressing, making her start to 
gag, and I started fucking her mouth.

She closed her eyes, moaning around me and bobbing her 
head with my strokes, and she started sucking harder 
after only a few thrusts. Apparently she was using it 
to distract herself from the steadily increasing orgasm 
that never quite happened, and I picked up the pace, 
pressing further down her throat with each thrust. I 
knew she could deep throat, since she'd done it before 
on occasion, and she figured out pretty fast that's 
what I was aiming for. She relaxed her throat, but kept 
working tricks with her tongue as I gradually fucked 
myself deeper into her mouth until her nose pressed 
against my stomach with each thrust.

Unlike Sara and Kim, I hadn't cum at all that day, so I 
built up pretty quickly. Her moaning increased around 
my cock as I quickened and shortened my thrusts, and 
then pressed even deeper into her mouth as my orgasm 
hit. I could feel her throat muscles working the length 
of my cock as she swallowed, pulling me deeper and 
keeping me hard in the process. I had to grab the 
headboard to steady myself as I leaned forward, curling 
my other hand in Kim's hair and keeping her from 
pulling back until my orgasm had completely subsided.

She kept sucking as I pulled her away, moving back as I 
did, and then gasped loudly and cried out when her 
mouth wasn't filled anymore. She strained forward, 
trying to get at my cock again, and I let her suck on 
the head for a minute. I turned around, cock still in 
Kim's mouth, to stop Sara's hand and move it to one of 
Kim's nipples, and then directed Sara's mouth at the 
other. Kim trembled and shook, moaning and sucking even 
harder than she had when I'd first put my dick in her 
mouth, and I had to pull back.

She cried out in frustration, trying to get at my cock 
again, but I moved to kneel beside her head.

"God damnit," she gasped, panting. "That almost got me 
off, bastard. When you came I was right - fucking - 
there. Give me your fucking cock again and stop teasing 
me! I need to fucking cum, damnit!"

She threw her head back and tried to dislodge Sara from 
her nipples, unsuccessfully, and she whimpered and 
moaned, swearing. I grinned and turned around, pulled 
the pillows out from under Kim's head and straddled her 
again, eliciting an "Ohgodthankyou." I dropped my cock 
into her mouth again and she sucked it up greedily as I 
glanced at the clock, thrusting into Kim's mouth as she 
bobbed her head, sucking hard. A little under twenty 
minutes left.

I leaned over Sara, holding myself up with one arm 
while I spread her legs and shoved two fingers into 
her. She moaned loudly against Kim's breast, shaking as 
her hips started rocking. Kim cried out as Sara pinched 
and sucked her nipples even harder as she came, and I 
shoved my cock deeper into her mouth, muffling her even 
more.

I pulled my fingers out of Sara before she'd finished 
cumming, making her moan, and dropped onto my elbow. I 
positioned my fingers at the entrance to Kim's pussy, 
pressing her head down against the bed as I buried my 
cock fully in her mouth, and then pistoned my fingers 
into her, once, hard, deep, and very fast, and then 
withdrew them just as quickly. Kim would have screamed 
if she'd been able, and the sudden constricting of her 
mouth and throat on me caught me off guard. I came 
again, gasping and trembling as I hung my head, 
watching her pussy clench and tremble in a not-quite 
orgasm. Just like a few minutes earlier, her throat and 
mouth muscles kept me hard, swallowing me and my seed 
down.

Kim drew in a gasping breath as I tumbled to the side, 
withdrawing from her mouth, then threw her head back 
and screamed and shook in frustration. I looked at her 
as she pounded her head against the bed, swearing and 
cursing as she cried.

"God damnit, Mike," she sniffled, her whole body 
twitching, but especially her thighs. "Let me fucking 
cum, god damnit! Pleeeeeease! I'm fucking begging you! 
Pleeeeeease!" She arched high, trying to bring her legs 
together, and then fell back, sobbing in frustration. 
"You have no fucking idea how god damn close you 
fucking put me with what you just did, you god damn 
bastard. I need to cum so fucking bad it fucking hurts! 
Let me cuuuuuuuum! Pleeeeeease!"

Her pussy was still spasming, I saw, more than it had 
been when I'd been watching it only a minute before. I 
smiled as I glanced at the clock.

"Seven minutes," I proclaimed, making Kim swear even 
more.

I grinned as I pulled Sara away from her sister's 
breasts and spread the strands of rope on her pussy so 
they lay to either side.

"One more treat, Kim: Sara."

Sara whimpered and covered her pussy with her hands, 
looking at me and pleading with her eyes. I only smiled 
and kissed her, shuffling her over to sit on Kim's 
face. She shivered as Kim's tongue made contact with 
her clit, struggling to keep from collapsing as she 
approached the edge of overload. I let her lean on me 
as I picked up the vibs I'd pulled out earlier, turned 
them on, turned the vib on Kim's clit all the way up, 
making her almost scream against her sister's pussy, 
and then held the extra vibs against her asshole and 
against her pussy entrance.

Both Sara and Kim were shaking uncontrollably now, Kim 
more so, and Sara clung to me, digging her fingers into 
my back as she fought to hold back yet another orgasm. 
There was only one problem: Kim knew every little 
secret to getting her sister to cum by using her mouth, 
and Sara shuddered through another three orgasms before 
the clock went off. She threw herself off Kim almost 
the same instant the first hideous buzz of the alarm 
sounded, placing her hands protectively over her pussy 
again and curling up. Kim was a lot more vocal about 
it.

"FUCK MEEEEEEEE!"

I shut off the alarm clock and lay on Kim, nestling my 
cock in the slit of her pussy after ripping the vib off 
her clit. She sighed and shuddered with relief, 
desperately rocking her hips up against me.

"Fuck. Me. Now." she hissed, clenching her teeth and 
staring at me, smoldering.

I had never seen her so completely possessed with lust, 
and that, along with the almost feverish heat coming 
off her, got me even harder, if that was even possible. 
I held her gaze, but spoke to Sara.

"Sara, love. Untie your sister here so she can be 
fucked properly. She deserves at least being able to 
gouge holes in my back after being teased so much."

She did, undoing the ropes first, and Kim immediately 
latched her legs around her, crushing me against her 
pussy and shaking hard. She was breathing fast and 
shallow, and I could feel her pussy trembling eagerly 
against my dick. That in itself made me so hard it 
hurt. She had at least enough restraint left to not try 
shoving her hand down between us and attempting to 
insert me.

She dug her fingers into the backs of my shoulders 
instead, and I pulled back some to position myself, her 
breathing getting even faster and more ragged in 
anticipation. I pulled my hand back up, slowly, and 
then shoved hard and fast into her, as deep as I could 
go.

Her orgasm was instantaneous and all-consuming. She 
gasped once, no more than a short lived squeak escaping 
her lips, tightened her grip on me so much I felt like 
she was trying to crush me to death, and went 
absolutely rigid as her pussy clamped down so hard on 
me I felt like she was dismembering me. She even 
stopped breathing during that first, painful 
contraction, which only half-registered with me at the 
time because of the pain. I could feel her juices 
squirt out around me, and then she started shaking.

"Oohfuck..." she breathed between one convulsion and 
the next, and then squeaked again as the next hit.

And then she passed out. Which did absolutely nothing 
to stop her orgasm or its intensity. But she was 
breathing again, even if it was whimpering breaths 
between ungodly strong convulsions of her cunt muscles. 
There was no way I could have pulled out even had I 
wanted to, so I simply held onto her, Kim's unconscious 
shaking transferring to me as well as I shut my eyes 
and clenched my jaw to tune out at least some of the 
pain.

Normally I loved feeling a woman cum, but this was an 
exception. The only reason the pain didn't cause me to 
go soft was because being in a woman and feeling her 
pussy squeeze only makes me even harder, which I'm sure 
is the only reason I wasn't immediately expelled by 
that first unbelievable contraction.

Slowly, the intensity of Kim's orgasm abated, though 
she remained unconscious for some minutes longer, her 
breathing leveling off again.

"How long have I been in her?" I asked Sara once Kim's 
squeezing had fallen to a more pleasurable level of 
pain.

"About three, four minutes," she answered from behind 
me, lying on the bed.

"God..." It felt like it had been a lot longer than 
that. "She's still cumming."

"I know. I can see her muscles contracting." She ran a 
finger lightly over my skin where I was joined with 
Kim, making me spasm and shiver. I could hear her smile 
when she spoke again, still running her fingers over 
me, arousing me even more. "It must be incredible, 
feeling her cum so hard." She tried pushing a finger in 
beside me, but couldn't manage it, so settled for 
teasing me some more.

"It hurts like you wouldn't believe. I won't be 
surprised if my dick's nothing but a giant bruise by 
tomorrow. It felt like she was pulverizing me when her 
orgasm first hit."

Sara mm'ed happily, scooping up Kim's juices and 
coating my balls with them, then smearing them on my 
asshole. She started circling a finger there, making me 
shake. I turned and looked back at her, shifting my 
position a bit to give her better access to Kim and me.

"If you're trying to make me cum, it isn't going to 
work. She's squeezing too hard still. She'd just stop 
it before it went very far."

She didn't stop, of course. Just gathered more of Kim's 
fluids and slicked my asshole and balls even more 
before slowly and gently starting to massage my balls. 
I muttered and dug my arms under Kim, wrapping them 
around her and holding onto her while Sara tortured me.

If there was anything sexual Sara could be considered 
an expert with, it was handjobs, and she kept me close 
to orgasm until Kim started to stir beneath me, which 
I'd guess was probably another three or four minutes.

She was still cumming, although a lot less intensely 
than she had been. She shook and moaned with each spasm 
of her pussy and turned her head toward me, pulling her 
fingers out of the gouges she had put in my back. I 
hadn't even noticed she'd made them until then, 
stinging pain flaring outward from each one as she 
removed her fingers. Not that it distracted long from 
Sara's ministrations, since the pain dulled pretty 
fast, and then I was close to orgasm again. I was 
vaguely aware of blood trickling down my sides.

"Mike..." Kim whispered.

She gasped and arched hard as Sara stuck a pair of 
fingers up her ass as well as mine and started working 
them in and out. Kim hadn't stopped cumming since I had 
entered her, so her orgasm only ramped up again, while 
mine started after only a few strokes of Sara's 
fingers, both pairs. Kim whimpered beneath me and 
started shaking even more while I held onto her even 
more tightly, feeling Sara's fingers massaging me from 
both sides and making me cum hard enough to counteract 
the convulsions of Kim's pussy. I bit her shoulder 
while I came, completely unable to even contemplate 
losing my hardness under the double attack of Sara's 
fingers and Kim's spasms.

Sara continued working her fingers in the two of us for 
another minute before she stopped and slowly pulled 
them out. Both Kim and I shuddered, Kim wrapping her 
legs around me again and holding me in her. She was 
panting and groggy, and I kept still, letting her catch 
her breath while her orgasm subsided. I was starting to 
think that wasn't entirely going to happen, since it 
had been about fifteen minutes now and her pussy had 
never entirely stopped convulsing on me. She was 
shaking uncontrollably now and held onto me, a little 
spasm running through her body with each contraction of 
her cunt.

"Mike," she said softly, smoothing a hand down my back. 
Her other pulled my face to where she could see it 
without moving too much. "You will-" spasm "-never-" 
spasm "-do that-" spasm "-to me again."

She dropped her hand on my head down to my back again, 
and I sealed her mouth with mine, giving her a very 
slow kiss. She returned it, her shaking and twitching 
gradually subsiding, though she continued to cum, 
albeit mildly.

As I mentioned, I knew Kim had multiple orgasms as long 
as she had something in her pussy, but I hadn't been 
expecting it to last for quite this long. Not moving in 
her, and with the kiss relaxing her, her orgasms slowed 
enough that one had mostly stopped before another, mild 
one claimed her. Even so, she was still having at least 
two orgasms every minute, even if they were fairly mild 
and I couldn't feel much of them.

She pushed me away after a few minutes to break the 
kiss, shaking ever so slightly and purring contentedly, 
running her fingers lightly over my back. She made no 
attempt to get me to leave her pussy, though.

"Never do that to me again, Mike." She pulled me down 
and nibbled my lip, and then just looked at me, half 
distracted by her constant orgasm. "That scared the 
hell out of me. I mean, I've passed out from cumming 
before, but nothing like that. It felt good, yeah, but 
it hurt so much I thought it was going to kill me. You 
have no idea how much it hurt."

I had to laugh at that, and I smiled, chagrined.

"I think I do. I've been stuck in you for about the 
last..." I looked at the clock. "Twenty minutes. If my 
dick's a giant bruise tomorrow, I'm going to blame you 
for it."

Kim purred again and shivered, and I flexed inside her, 
making her gasp and her pussy spasm harder.

"Almost the longest orgasm I've ever had. It's starting 
to hurt now, though."

"Almost?"

"Yeah. I was-" she gasped and clutched at me as I 
flexed in her again, "-masturbating one time and wanted 
to see how long I could handle cumming, 'cause I can't-
" another gasp and twitch as I flexed again, "-stop 
cumming if I have something in me."

I started moving in her, and she moaned as she started 
rocking her hips to match, locking her legs around me 
again. I kept the pace slow, making her shiver and lean 
her head back as I pulled out almost all the way and 
then buried myself in her again in a hard, fast stroke.

"How long did you manage to go?"

"God..." She gasped as I started moving faster. "Thirty 
two... minutes. But... I had to stop... because... it 
was... hurting too much."

"Let's double that."

I grinned as her eyes opened wide and she arched hard, 
her orgasm suddenly intensifying. I had to stop moving, 
but I flexed inside her every time her pussy spasmed, 
making her moan and shake even more.

"Please no. It's going to hurt too much."

"That was part of the deal, though. If I couldn't make 
you cum without me or Sara screwing you or putting 
something inside you, me and Sara would fuck you 
senseless." I looked over at Sara, who was now sitting 
beside us. "Cuff her again, to the middle post this 
time so we can turn her over later."

Kim whimpered and would have struggled a lot more if I 
hadn't started moving hard and fast in her, causing her 
orgasm to build up to match so it was too overwhelming 
for her to fight being cuffed again. She shuddered as 
her hips rocked up to meet mine as I thrust into her, 
and then stopped and held deep once her hands were 
bound again. She shivered under me, moaning with each 
contraction of her pussy, and I extricated my arms from 
under her.

I dragged Sara over as I straightened, Kim and me 
parting noisily as our sweaty skin pulled apart. I 
kissed her deeply as I rubbed her clit, and she came 
after only a few seconds, shuddering and sagging. 
Always a good indication of how over-sensitive she was, 
how fast she came, and I continued working her clit 
while her orgasm subsided, knowing it would quickly 
bring her to climax again. I didn't want that just yet, 
and stopped as she was getting close, then fixed her 
rope so her clit was again captured between the two 
strands.

"Go get your strap-on," I told her, pulling her close 
and giving her a deep kiss, nibbling her lip. "But 
don't cum until you're fucking Kim."

Kim drew in a sudden breath at that, her pussy 
tightening around me, and Sara moaned. She got moving, 
albeit elaborately slow so she could hold back the 
orgasm I had put her right on the edge of, and I 
watched her as I started to fuck Kim again. She stopped 
a few times as she bent over to dig around in the toy 
box in the closet, and stopped a few times as she 
straightened, as well. She had to lean against the wall 
to support herself while she pulled the strap-on over 
her feet and up her legs, which were shaking. She had 
tightened her stomach, too, I saw, to help her avoid 
climax.

She eyed the distance between her and the bed, a mere 
five feet, and then took two quick steps to stop beside 
the bed. She trembled and clenched her fists, 
tightening her stomach even more, as well as her 
thighs, which quivered. I could see her clit poking 
from between the ropes, a pink nub, and I reached over 
after a few seconds, dragging her onto the bed as I 
pulled out of a squirming Kim. They both gasped, Sara 
because of the sudden movement inflicted on her clit 
and pushing her toward orgasm, Kim because of the 
sudden emptiness.

Sara crawled hurriedly over to Kim and shakily 
positioned the strap-on, then shoved it violently in as 
she collapsed onto her sister, shuddering as she came. 
Kim cried out, wrapping her arms and legs around Sara 
and clinging to her, shaking.

I let Sara's orgasm subside, then pulled Kim's arms off 
her and straightened her. I knelt beside Kim, whose 
stomach was fluttering now, and leaned Sara against me. 
She draped her arms around my shoulders, sagging 
against me as I dropped my hands down and started 
pinching and tweaking Kim's nipples. That almost made 
her scream, and she arched up into my fingers and 
started writhing side to side, trying to get away. It 
didn't work, only making me tighten my grip more, and 
she subsided when she figured that out, moaning and 
shaking even more.

"Fuck her," I whispered in Sara's ear. "Fuck her like 
she needs to be, hard and fast."

Sara screwed up her face and started to fuck Kim, 
though slowly, and then stopped. She whimpered and 
shook her head.

"I can't," she said. "It hurts to cum anymore, and you 
know how sensitive I am now and what that does to me."

I let go of Kim's nipples, which made her give out a 
small cry, and wrapped my arms around Sara, giving her 
more support as she leaned on me. I gave her a gentle 
kiss, rubbing her back.

"You can do it. Don't you think, Kim?" I looked down at 
her, but she had her eyes closed, so looked back at 
Sara.

"Fuck me, Sara," Kim gasped, rocking her hips against 
her sister and the strap-on that was buried in her. 
"If... we're going... to be sore... then... it 
should... at least... be... enjoyable." She tightened 
her legs around Sara, pulling her closer and causing 
the strap-on to sink completely into her, making her 
moan.

Sara squeezed her eyes closed and bit down on my 
shoulder, lightly, and shook as she started to fuck Kim 
with the strap-on. She stopped after only a few 
strokes, her fingers tightening against my back as Kim 
moaned in frustration.

"Am I allowed to cum?"

I grinned and moved a hand to her breasts to pinch her 
nipples, making her draw in a sharp breath. Kim gave a 
breathless laugh.

"As long as you're fucking Kim, I want you to cum every 
time you start feeling one building."

She whimpered and shivered, but nodded and started 
fucking Kim again, shuddering and clutching at me as 
she came. Only she was still doing it slowly, and I 
made her go faster, eliciting more whimpering from her 
and moans from Kim, who was shaking all over by that 
point. I kept prompting her to go faster until she was 
shuddering without stop, biting my shoulder and using 
me to keep her upright, as she didn't have the strength 
for it in such a condition.

I watched the clock, keeping Sara going for fifteen 
minutes, tweaking her nipples the whole time, and then 
let her stop. She cried with relief, sagging entirely 
against me and shaking uncontrollably, twitching as her 
latest orgasm subsided.

"Hurts..." she breathed, her fingers clawing lightly at 
my back.

"Fuck me more," Kim said, pulling Sara closer and 
grinding against her hips and the strap-on. Her stomach 
muscles were fluttering from over exertion, as were 
Sara's, and she sounded completely zoned, which made me 
unsure she was entirely aware of what she was saying.

Sara only moaned in desperation, but did as told, 
starting to fuck Kim again slowly but quickly building 
the pace. I only held her that time, and she shuddered 
against me, completely losing any coherency as she rode 
through another dozen and a half or so orgasms.

I let her go for another ten minutes before stopping 
her, Kim crying out when I did, and moved her back, Kim 
crying out even more as the strap-on fell out of her. I 
think she had lost any coherency, as well, with that 
last fuck. I grabbed the vib I'd put on her clit 
earlier, wiped her pussy clean with the edge of a spare 
blanket, making her shiver as the roughness passed over 
her clit, and then reattached the vib and turned it on 
to its highest setting. She gasped as her eyes widened, 
and she squirmed her legs, digging her feet against the 
bed.

I lay down next to her and dragged her on top of me, 
shifting her so I slipped into her. She shivered and 
moaned as I did, going limp and nibbling at my 
shoulder, the vib and me inside her intensifying her 
orgasm. I started to slowly fuck her, looking up at 
Sara, who was watching with glazed eyes.

"Fuck her ass, and do it hard and fast."

Kim cried out at hearing that, squirming on top of me 
as Sara moved forward, almost falling over as another 
orgasm hit her. Sara leaned over Kim and me, supporting 
herself on one shaky arm while she positioned the 
strap-on against her sister's ass, and then slowly 
shoved her hips forward, driving it into Kim. Kim let 
out a long moan as the strap-on sank completely into 
her ass, and her orgasm became even stronger.

Sara and I started to fuck her in unison, driving her 
orgasm even higher, and she started shaking even more 
than she already had been. I paused for a half second 
so Sara and I were pistoning into Kim with alternating 
strokes, Sara pushing in as I was pulling back, Sara 
pulling back as I was pushing in. Kim's orgasm 
intensified even more doing that, and I was starting to 
have troubles getting back in with as hard as she was 
squeezing. I shortened my strokes, but sped them up, 
which pushed Kim even higher.

I had to stop completely after another minute or two 
because Kim was starting to cum so hard I couldn't move 
at all, so I just buried myself as deep as I could into 
her and let Sara fuck her. Which she was holding up to 
surprisingly well, even though she was shaking so much 
from near constant orgasms that I thought she would 
collapse at any moment. I was getting close to one 
myself, and feeling Sara's strap-on work in and out of 
Kim was enough to put me over.

Kim's eyes widened as she felt me cum, and she moaned 
as her eyes rolled back as orgasm grew even stronger 
and she passed out. Sara followed suit soon after, 
letting out a shaky sigh and collapsing on top of Kim. 
She was asleep immediately, and I had to pull her to 
the side and off of Kim in order to extricate myself.

I removed the strap-on and rope from Sara first, 
cleaned her up, then unshackled Kim and did the same. I 
got a new blanket from the closet after pulling off the 
old one, which was soaked through with Kim's juices, 
tossed the new blanket over the two of them, then 
crawled under it myself and passed out alongside them.

Sara and Kim slept for a good eleven hours, and I slept 
for almost the same. Nothing even remotely sexual 
happened the next day after what we had done the day 
before, both Sara and Kim being much too sore to find 
even mild flirtation appealing.
