During a slow day at work when it was just Mae and Stacy working, Stacy opened up to Mae and told her that she found me "hot" and that she was curious...about having sex with my wife too. Of course, my wife who can hide nothing from me blurted this out immediately upon coming home. At first I played it cool and said, "It isn't happening, Stacy can cheat on her husband with some random dude and we can laugh about how it took her so long to cheat on her asshole husband". My wife and I talked. He plunged his hard cock into my butt hole causing me to 'UUUUUUUUUUUUNNNNHHHHUUUHHNNNNYUUUUNNN,' moan from pain and pleasure. He wasn't all that large but he was solid and strong as a bull. He had me by th waist and was plowing his five or six inch cock in to my butt like he weren't going to get any more sex. Ten minutes after he penetrated my anus he shot his load of old man spunk up my butt. When he pulled from my anus, one of the smaller guys was stripping off his pants, his cock was. .. why don't you scoot down here."Scoot down. *Scoot down? There was no scooting down without putting my crotch in her face. I was wearing tighty whitey type underwear, and my erection was pressed to my thigh. I was laying on her bed, she was on the floor. Scooting down meant putting me in a very weird position, but I did."Lay back. And don't move. Ok? Don't move. Just lay there, ok? I love you."She patted my thigh a couple times to affirm what she'd said. I nodded, with my eyes closed.And she. "I did make one change that may effect you on that regards though." A sheepish smile crosses her face. "You did saw the part about changing a person into an animal right?"You nod slowly a bit scared. "Well, it would have been fun to experiment with a great big horse cock for a night or two, but I found something even more interesting. Do you know what a Succubus is?" A vampire, but takes life from sex instead of blood?" You're shocked, but it kind of makes sense with how much you've been.
