Sara smiled through her tears and hugged me, then she kissed me and not a sisterly kiss either. I immediately responded with passion, our tongues were...searching out for each other's, my hands went to her ass, as her's went around my neck. We stayed in the thralls of passion for what seemed like forever. I explored her body, I gripped her ass cheeks then I moved one hand up to her breast and played with her nipples. This got an immediate response, her nipples got hard and as big as good sized. My cock was hard. Moments later I heard her walking down the hall again, I closed my eyes. She came into my room, I could feel her standing over me. My cover was momentarily moved back, I could feel her breath on my face, then she had covered me again and quickly left, closing the door behind her. I looked around the room, massaged my hard cock and then went back to sleep. I would have a wank later. I showered and dressed for lunch. Jessica was her normal self, asking me if I slept well etc. We. And then she met my stepdad, which led to meeting my stepsister. She was every bit as attractive as my mom. She was a little chubby, and her tits were only 34 DD, but her ass was huge. It was hard not to notice it sticking out, especially wearing her yoga shorts.She had a boyfriend who was in his early twenties. Every night became torture. My room was perpendicular to hers and mom and dad's rooms. And when her boyfriend was over, it was like a cacophony of orgasmic pleasure coming from both. Was this the same girl who only hours ago told me that, “I can take care of myself” in the most defiant look on her face in the whole world. Now her face was radiant and jovial, full of life and joy like any normal teenage girl. She had transformed into quite a beauty and I was noticing it. “What do you think, Gramps?” called out Kristy with a big grin on her face. “Well, I think she cleans up pretty good,” I said admiringly. Cathy face lit up and both of the girls laughed and squealed.
