My Shemale Stepmother Part 2

"I've got to keep busy when you're not around," she grinned enjoying both his and my discomfort, "How does it feel, honey, hearing your son, your masculine pride and joy beg to have his virgin ass fucked by his own stepmum? To hear him beg to be her bitch and be fucked like his daddy? I guess being a cock loving sissy slut must run in your family."

I looked up at my dad and couldn't believe that he was getting hard, I could see his erection outlined in his jeans. It seemed that the sight of his son having his ass violated by his own girlfriend and her humiliatingly taunting him about it was a turn on for him. Obviously this love of humiliation ran in the family too.

"Come and join us," Carla said, "We can all see you want a piece of this. A father should be there for his sissy son at such important times of his life."

My dad obviously wasn't immune to Carla's commanding abilities as he began to strip off until he was as naked as I was. His cock was already pretty hard from watching us and I couldn't help but admire it, it might have been about half the size of Carla's but it looked good enough to eat. What had happened to me? What had Carla turned me into? I was salivating over my own father's cock.

"You know, bitch, your daddy is quite the skilled cocksucker," Carla said as she continued to fuck me with a steady, aggressive rhythm, "Maybe he could teach you a thing or two. Come here, Joe," she said to my dad. She pulled him into a passionate kiss as he caressed her breasts and then whispered something in his ear. I tried to look back and see what was happening but I was impaled on my stepmum's full eight inches and could hardly move except in time with her thrusts.

"No," my dad said, "I can't."

"You will do as I say, slave," Carla said angrily, "You know you want to see what your little slut boy of a son tastes like."

What? What was she asking him to do?
