"... let you fuck my ass like you wanted to last night."

Your offer hangs in the air for a few seconds. Peter seems like he's contemplating it. He even drops a hand down to his crotch and starts rubbing himself through the fabric. You hate that that's a good sign.

But you don't have all day. Both of you have to get ready for school soon. Frustrated as he takes his time to answer, you say, "Come on, what-"

"I don't think so, Sarah," he finally answers. The little shit must have been waiting for you to start talking so he could interrupt you on purpose. It's such an annoying power play, and you hate when he does it. "An ass fuck was the original request, which you so callously declined." You note with a curled lip of disgust that he's slowly slipping his sweatpants down. "I need something beyond a normal anal dose, you get me?"

You rub the bridge of your nose with two fingers. "Okay, I'll suck it clean after," you say. You're not expecting this to be enough, but you have to try anyway. Ass-to-mouth is not the filthy act it once was. Your daily, government-provided pill makes sure of that. It's primarily a contraceptive and natural lubricant stimulator, to make accepting doses easier. However, one of its side effects is keeping the first few inches of the rectum clean. You never understood exactly how it works, but it sure makes anal easier.

"You would have done that anyway," he points out, correctly. It helps maximize dosage output. All girls were taught as such. Now his pants are on the floor, and he's got his half hard dick in hand.

"I'll let you have a few pumps in my pussy first, for lube." Vaginal **** is still slightly more of a taboo than the more clinical oral or anal. Maybe it would be enough to entice him.

"Who needs lube?" He's slowly stroking, working himself up to a full erection. You bite your tongue, resisting the urge to tell him you'd like some lube. He never cared about that before and isn't likely to start caring now.

"Umm, I'll let you call me names," you offer, feeling a knot in your stomach tighten. You know he's going to milk this for all it's worth, but you're too afraid to bring up the really kinky stuff you're sure he's aiming for.

"You can do better than that, slut." Peter smirks, now fully hard.

Your shoulders slump. You know what he wants. "Fine!" you spit. "I'll let you ass fuck me, and..."
