Eye for an eye, ass for an ass

"And here I thought I was safe..." Says Rachel, with a much exaggerated tone of misery to her voice, though the curious gleam in her eyes are still betraying her excitement. And she doesn't make a move to escape when you walk up to her either, but simply gets up on her knees in the couch, and spreading her legs to allow your inspection of her lovely behind.

"Hmmm..." You ponder for yourself, just loud enough for both of the girls to hear you, and then gently slide your thumb through the abundant moisture along your house mate's labia. The touch forces a soft moan from her lips, and then another as you reach her sensitive clit. You only stay there long enough to nudge it however, before tracing all the way back around her slick wet opening, and then finally start pushing inside of her. "What do you say, Rachel...?"

"Well, I.... uhnnn... certainly owe you one!" She purrs in reply, making it easy to tell that she's certainly willing for a try at least. And with that you pull your finger back out of her again, now fully lubricated with her juices, and slide it slowly up to the puckered little entrance that is her sphincter. Again your exploring touch is making her gasp in pleasure, though it rises to a deeper groan while you cautiously start pushing inside of her.

It seems like Rachel is enjoying this a little too much though, if it's really supposed to work as some kind of ****. But Kate doesn't seem to mind that at all, as she simply stands by and smiles while your finger pushes even deeper into the other girl's ass.

"Need my assistance...?" The blonde asks you quietly, when you're trying to unbuckle your belt with just one hand, but then barely waits for you to answer. Soon enough she's managed to free you raging hardon of it's confinements, and you notice her staring at it for a moment - like if truly surprised by your size. You'd thought she'd be used to seeing things like that, considering that both Rachel's and even her own are very close to rivaling yours, but still she can't seem to take her eyes off it.

You don't give her much time for a full inspection though, but quickly bury yourself deep into your lover's velvet sheath, causing another gasp to erupt from deep down Rachel's throat. From there you give her plenty of opportunity to have a look however, as you start pumping with long and slow strokes - pulling almost all the way out, before returning back inside again. And all the time you keep your thumb lodged firmly into Rachel's tight behind, thus forcing her into an angle that even better exposes her bits to the audience.

"Oh, f-fuck...!" The brunetter moans as you finally start moving your finger again, allowing her a feel of getting fucked in both holes at once, though you can guess it's not entirely pleasant to her with the makeshift lubrication becoming sticky and causing too much friction friction. Kate is quick to find a solution however, as she's suddenly at your side with a tube of lubrication in hand, and immediately start applying it in generous amounts directly down the crack of your lover's bottom.

Soon you can move your finger freely again, much to everyone's delight, and it isn't long before you decide to have a go at what you actually came for...

"Huh...?" The Rachel gasps a little as you suddenly pull all the way back out of her, and it seems like she's momentarily forgotten about what's about to come. But then she swiftly bends over again, and you can see her trying to relax, while also bracing herself against the back of the couch. If she was ever unsure of this idea before you started, she certainly doesn't seem like she's about to back out right now!

"Just one thing, John..." She gasps, and then bites her lip in anticipation while she can feel your bulbous cockhead lining up against the very entrance of her backdoor. "Don't be gentle with me! I... I sure wasn't to Kate...!"

"Is that true...?" You ask the blonde at your side, both curious and a little bit worried for what actually occured between them on that day, but feel quite reassured when she just blushes and nods her head - with the hint of a smile on her lips.

"That doesn't mean she was rough with me either..." She admits, while still smiling softly at the memory. "Though... I couldn't sit upright on a chair for several days...!"

"That bad?" You flash her a grin, seeing as she doesn't appear to have any lasting troubles from the experience. But then you return your attention to the task at hand, and with a slow push you watch as the very tip of your cockhead starts painstakingly making it's way through the outer rim of Rachel's tight sphincter - forcing another series of gutural low groans from her soft lips.

It takes a couple more tries to get the hang of it, especially because you're really a tad too big for this, which in turn makes you wonder even more what it must've been like for Kate - considering how she's smaller in stature than Rachel, and seemingly more fragile overall. Your imagination only serves to spur you on however, and before long you've pushed more than half of your impressive length deep into your lover's bowels - accompanied by the various little sounds that continues to erupt from the other end.

Then you try moving around a bit, after applying even more of the bottled lubricant, and eventually start sawing your way ever deeper inside of this incredible tightness. You could easily get used to this kind of stuff, you think to yourself, and smile as Rachel seems to reflect your thoughts exactly with another little vocal outburst.

"Go on...!" You suddenly hear Kate start urging you on, and realize that she's practically been leaning on your side for the last couple of minutes - staring down at your rock hard member, while it continues to plow into Rachel's behind. The idea of having her watch you - along with the feeling of her firm naked breasts against your arm - takes the whole thing to another level of excitement for you, and suddenly you find yourself getting way much closer to your peak than you'd anticipated.

"Oh, fuck...!" You grunt, and then again as you can feel your lover's insides squeezing you even tighter, practically milking your shaft of your precious semen. And before you know it you feel your cock exploding in a torrent of sticky hot semen, that's getting pumped deep and directly into Rachel's bowels.

You can't stop your thrusting however, as it almost hurts when she's gripping you like a vice, making you fear that your shaft would actually explode for real if your urethra got shut any tighter. And the pace increases as well, which in turn makes both of you howl even louder, until you're finally reaching the end of your unusually prolonged climax.

"Oh, g-god..." Rachel whispers as you slowly withdraw from her, and then she toppled forwards against the back of the couch - completely spent from the endeavor, with her ass still gaping wide open, and a steady trickle of your cum leaking out of that well-used hole. But even so she's got a look of deep satisfaction on her pretty face, despite the hints of some minor discomfort, and she even manages a loving little smile while you grab her some paper to prevent your seed making a total mess on the couch and floor...

"Well deserved...!" Smiles Kate at the sight of the other girl's exhausted body - covered now with a heavy sheen of perspiration -, and you can tell of her own arousal like you were reading from an open book. On this matter you wonder again how she could possibly not want to stick it to Rachel herself one day...
