“When you want her on all fours to follow you just tell her to ‘Heel’. If you want her to stand up for any reason then you can just tell her, �...at ease’, or ‘as you were’, like you did earlier. It really isn’t rocket science,” Eddie acted like it was no big deal but I was already nervous I would blow this and forget something.“Heel Charity,” I said more forcefully, and Eddie told me that I was a natural although I think he was just being charitable.Charity got down on her hands and knees, ready. I started fucking her as hard as I could, while I was I could feel her tense up and cum, so I slowed. "No don't slow down keep doing it hard I want it hard and want to cum more than once during sex". I kept pounding her and by the time I cum she must have cum about four or five times.When we had done we lay in each others arms saying nothing, then I said "what do we do now"? Lisa looked at me "well I think we should fuck some more". Then Lisa looked at me and said "do you want to have an affair. He knew now, it didn't matter that I was a guy, his cock found my ass and with one good push he started to fuck me, with that the fist orgasm hit hard, bringing more attention to my fun, as Sue took on guy after guy who wanted to fuck her doggy cum filled ass now, I was now taking all his cock, just the knot left to go.I held him out as long as I could, knowing that once knotted he will cum, he fucked me good, growling trying now to knot with me, but I held firm, a few guys saying that it wont. She always tried to hide these things from me. Their love life seemed to fade as well.After one particularly heavy drinking night, dad really hit her across the face. Seemingly for no reason.I had been in my room as usual. I heard the commotion and then mom running into their room next to mine. I imagined she was laying face down on her bed crying, as I heard the moans.I went down to try talking with dad but then he hit me too. He was BIG. I mean BIG. I was just 16, and still needed to pack.
