Well, since Lin's all lubed up...

"Hehe, wow, that was great Doug. You must be pretty popular with the girls at school." Lin says from above you, her hand now lightly stroking her cock, slick with your saliva. "Say, Crystal, I've got a little question for you." She asks, looking over toward your sister.

"Yeah Lin?" Crystal responds, looking away from you, apparently satisfied that you're okay. "I was wondering, since, you know, I'm already lubed up and all..." Lin says, trailing off before she could finish her sentence, but her question still come through quite clearly to you, at least.

"Well, I don't see why not, I mean, so long as no one else has any objections, of course." As she says this, Crystal looks at the two other girls, waiting for them to speak their piece. Debby simply shakes her head, indicating that she has no problem, and Jackie simply says, "I'm fine with it, just so long as I get a turn next!" Giggling all the while.

"Well, there you have it Doug. Unless you want to run away, I'd suggest you bend over the bed so we can, hehe, loosen you up a bit sweetie." Crystal says, apparently quite pleased that she's about to watch her little brother lose his virginity. You, on the other hand, are somewhat dumbstruck by this turn of events. Just moments ago you had given a girl you barely know the first blowjob of your life, and if you didn't do something soon, you'd be losing your virginity to that same girl in just a few minutes. Maybe it's just the shock of it all, or maybe it's your teenage hormones getting the best of you, or maybe you simply aren't sure of how else to respond, but next thing you know, you find your self bending over the edge of your sisters bed, your virginal ass exposed for all the girls to see.

Other than a few whispers however, the girls don't really seem to be saying much, though you think you hear the word, "tight" being thrown around a bit. Right before you can muster the courage to turn to face them however, you feel a pair of feminine hand upon your cheeks, followed by what you think is an appreciative moan. "Well, it looks like you really are a virgin Doug. I'll admit I'm a little surprised, I figured a cute boy like you would be hard-pressed to keep the girls away. Don't worry though sweetie, we're gonna be changing that real soon."

You're a bit surprised when you hear your sister's voice speaking to you rather than Lin's, and you also get the feeling that those are her hand on your rear as well. Surely she doesn't intend to be the one to, "loosen you up" she is your sister after all! However, it seem that she does, in fact, intend to do that herself, as you feel what must be her lips finding your tight sphincter, kissing your anus lightly. Her tongue tickles and teases your asshole, licking across it from your balls upward, and you can't help but stand on the tips of your toes! You hitch a sharp breath as she starts to fondle your penis, only eight inches long and not particularly thick, but straining with excitement as Crystal wraps her gentle fingers around the shaft and squeezes.

"Mmm, God Doug, you have such a pretty asshole, I can't wait to see Lin fuck it." Crystal says, momentarily pulling her mouth away from your now rather slippery hole, before she latches on to your sack, moaning around your balls as she takes them into her mouth, sucking hard at your scrotum.

She takes both of your testes between her lips at once and you wriggle your hips in response, making faces at the sensation of having your tender nuts teased almost painfully. Crystal is really sucking on them hard! Her tongue moves around and between them as your nearly-hairless ball sack was pulled taut away from your pelvis. She bobs her head, sort of, as if giving you a blowjob that way, with your ball sack in her mouth, before pulling away to tongue your ass for a while longer, and you find yourself shivering with the raw pleasure of it.

However, this doesn't last long, as after a few minutes you feel Crystal pull away from you, moaning softly to herself. "Okay, okay. Lin, I think he's ready for you." She says, and if you weren't breathing so hard yourself, you'd notice that she sounds rather out-of-breath. However, you don't really have much time to think, because as soon as Crystal finished talking, you feel a new pair of hand on your hips, gently encouraging you to roll over.

"Finally! On your back, Doug!" Lin says, "I wanna do you right."

"Oh, that's sexy!" Jackie giggles and shakes her head at you as Lin climbs on top of you, before pulling your legs over her shoulders, getting ready to fuck you face to face like a groom to his bride on their wedding night.

"Be nice, Lin!" Crystal laughs, stepping back a bit to get a better view of the "show". "I don't think he knows up from down anymore, look at him!"

Your ass rolls off the mattress, your knees nearly touching your shoulders as Lin pins you helplessly to the bed. She slowly, carefully lines her cock up with your ass, making sure that it's a straight shot. You can feel her slippery, slimy head rubbing against your loosened entrance, eager to get inside of you. Then, without any warning, she enters you. For a moment you feel a burning sensation, not terribly painful, but you still can't help but wish she had told you first. Afterwords, for maybe a minute or so, she just sits there, moving back and forth slowly, working more of her impressive length into you. Soon, the burning turns into a sort of throbbing sensation, it's somewhat strange, but not entirely unpleasant really.

Noticing that you've started to relax, Lin starts slamming her cock inside you as far as she could. You can feel her smooth, plum-sized balls against your skin, soft and warm as she begins to grind her pelvis against your ass. Out of the corner of your eye, you can see the other girl's eyes go to your now hard cock, wet and moving wildly as the two of you fuck. It slaps against your stomach with soft wet sounds that only add to your embarrassment, and it is clear that the girls are amused, even pleased by what they're witnessing, especially your sister.

"So Dougie like it in his ass, huh?" Debby says, smiling at Crystal. "I wasn't sure he would. What a slut."

"He's a sweetie," Lin giggled, holding you down against the bed, her stiff nipples rubbing against yours. "Can't get enough of my cock," she said into my ear. "Can you, pussy?"

After that exchange, she beings pumping you hard with a straight shot into the burning confines of your well stretched rectum. You moan loudly and then give a sharp yelp of pleasure and pain when Lin's swollen cockhead finds your prostate. She caresses you there, or so it seems, rubbing that sensitive spot and making you love it. Her big, sperm filled balls slap your ass mercilessly and the sounds of your fucking fill the bedroom.

When Lin finally cum after a good four or five minutes of that, she begins kissing you deeply. You suck her tongue almost subconsiously, with your eyes closed and your hands clutching her tan thighs as Lin holds her spurting cock deep. Hot semen floods into you with an unfamiliar, if somewhat soothing sensation. You know you're being used by her, filled with her rich sperm, and contrary to every expectation you might have had, you aren't fighting it at all. You're too busy cumming with her, your smaller dick jerking between your bodies as your semen spread in a thin, sticky glaze. Lin's supple tummy rubs against yours as she keeps her stiff cock lodged inside you, and the pressure against your own (comparatively) much smaller penis was everything you'd needed.

Slowly, she pulls her softening member from your ass, leaving you with a kind of empty feeling, one you've never experienced before. Once she's pulled out of you completely, she stand up from the bed, stretching slightly as she does so.

"That was a lot of fun, pussy, I can't wait to see you on Monday," Lin said, kissing you one last time on the top of your head before turning to face the others. "Alright girls, so who wants the next ride on the Dougie-Go-Round?"
