Then Nick recognized the look on Betsy's face. Uncle Bob's finger had to be in the blonde's shitter!"Oh, Daddy!" Betsy moaned. "I think I've gotta hav... that big cock of yours! And I want it up my asshole!"By the time Bob and the girls were in position, their observers had retreated back down to the porch. So there was no one else to see as the twins stretched across the width of the narrow bed, their faces down and their asses upward."I'm not gonna do it," Becky said. She cupped her ass. I don't know how I held out form cumming for so long and I never wanted it to end. Finally he pushed me off and getting up instructed Becky to lay across the table with her head hanging off one side. He grabbed a kitchen towel and while wiping his cock off asked me "Billy have you ever fucked a girl?" Embarrassed I told him no. "Well today is your day boy, we're going to make you a man. Get over there between her legs. Becky had her feet up on the table with her knees bent. I pushed her legs. I want to be turned into the most perfect sissy slut slave. I have for… I don’t know how long now. I do however know when I started to want more than porn, I recently got out of a long relationship, it was a good relationship and the sex was good, even if I was only really lying to myself, she was into slapping and choking and those kinds of things. I was too, I got hard with my hand round her throat or spanking her and whipping her, but i think that was all really the part of me that wanted to. It’s my duty to discipline you in the way your father seems to not be able to his precious darling. Well I am not in danger of getting a swelled heart, but I’m going to give you a swelled butt. Of course if I spanked your mature butt with my hand I would get the worse of that deal, so missy that means frying your rear with my wooden hairbrush and that is exactly what you better prepare yourself for happening this very moment. And, I intend to go farther, no matter how much you groan, whine beg.
