Just enjoy Amy for now
From Torg Adventure
You figure that since Sam is a captive audience for the hot sex between you and Amy, you might as well keep letting her watch. You hope that she's enjoying it even a fraction as much as you are. Maybe it's breaking down her sexual inhibitions. You figure it's at least not jeopardizing the one time promised to you by fighting her the other day.
Your mother is certainly enjoying the show, although you already knew that she got off on watching her children doing each other. She seems to enjoy it almost as much as actually getting plowed by you. At the rate that your mother's juices are soaking out of her pussy around her fingers, Amy is going to need to need a new chair.
And to just devote yourself to screwing Amy is an easy decision to make, especially now that her reservations are fading away too. Even without the spankings this time around, she's plenty involved in the action.
"Amy, I'm starting to think that you might be just a little bi," you mom teases, her voice sexily husky.
Amy lifts her hand towards your Mom, and holds her thumb and forefinger about half an inch apart. "Maybe just a little, Mom..." Then her leans her head back, a small orgasm rocking her body. She lowers her head, still taking your thrusts, but moves her fingers much farther apart now. "...maybe more than just a little..."
"Or maybe you just like it so much because it's your brother..." Your mom says softly.
"That's a... a horrible thing to say about your daughter," Amy moans, not sounding too upset. "Besides, it sounds like you enjoyed it an awful lot, too."
"Oh, yes..." Your mom purrs. "God help me, yes I did."
"I get to watch next time," Amy says suddenly, looking at your mother.
"What? No..." Your mom says, clearly startled. Not startled enough to stop fingering herself though.
"It's only fair, Mom," Amy insists. She's got both hands under her now, and slightly forward, holding her body in place against your ever increasing pounding of her pussy. "You've watched Max and I all this time."
"Amy... I can't..." your mom says. She still apparently has some sense of right and wrong, or at least some sense of modesty which apparently having someone watch while her son fucks her would violate.
"You can, and you will, Mom," you say firmly. "The next time I screw you, Amy gets to see everything." You smile, at a joke that neither of them would get understand at the moment. "Hell, whoever I want to gets to watch." You wonder what effect Sam seeing your screw your mother would have on her.
"Okay, Max," your mom says meekly, although not without some reservation still. With her aversion to an audience, that should make things more interesting. Maybe that was why she reacted so extremely to finding out that Amy has put a camera in her room.
"Thank you, Max," Amy says with real gratitude in her voice. Both your mom and Amy apparently had strong voyeuristic streaks. You hoped that held true for Sam as well.
You kiss her salty lips again. "You can express your gratitude by having my baby, Amy. I want to fuck you when your good and pregnant like Mom is, but with my baby inside of me."
"Okay!" Amy says readily enough, her previous objections to pregnancy seeming to be totally gone. Or maybe it was just her speaking in the heat of the moment. "I'm probably knocked up already, after all this..." She slips her hand in between your two bodies, putting it low on her belly. "But just to be safe, I'll need more of your baby juice... right... here."
"Let me see if I understand you right," you tell her. Then you sink your cock into her, and groan as you release into her. "Right there?"
Amy cries out, and her other hand claws at the bedsheets as she cums. "Yes! Right there, Max! I can feel it in me, and under my hand... Oh!" Her cunt squeezes your cock eagerly, milking it.
You hear the chair your mom is sitting on actually shake against the floor a little as your Mom orgasms as well, even if you don't see it happen directly. You thrust in and out of Amy a few more times, to help her prolong her orgasm, and to maybe push more of your cum deeper into her, only stopping and rolling off of her once she is finished.
"Fuck it," she says, panting heavily as she looks up at the ceiling. "Who am I kidding? I'm totally bi." She glances over at you. "Well, at least as far as getting it on with my brother is concerned, I guess."
"There hasn't been a woman in our family yet who hasn't loved cock, Amy," your mom says wearily, but contentedly. She's drenched in perspiration, and the chair seat is drenched with other fluids. Yeah, definitely a new chair.
You're wondering if you shouldn't give your mom a chance to demonstrate her love of cock right now. With Amy watching. And Sam, of course. Although part of you wondered how Sam was faring through all of this. You could try to draw her into this bit of family fun right now, in front of your Mom and Amy. Or you could make an excuse to get them out of the room first. Then again, it sounds like Amy wouldn't turn down another go at your cock, either.
Your mom's turn now, or do Amy again? Or check on Sam, either right now, or more privately?
