As my cock reached her lips, I gently pushed inside her, just parting her a little. She reached up and grabbed her hands behind my neck and arched her...back to present herself to my cock. Please fuck me now she pleaded as she tried to impale herself on me. I moved my hips away so that only the tip of my cock was inside her. As she arched her back, she wrapped her legs around my back and gripped me tightly. Her pussy was so warm and wet as I decided it was time. Slowly but steadily I pushed. "I'm just fifteen, my birthday was last month," she said. "Oh God."She groaned as his hands once again squeezed her breasts."Yeah, you're a nice piece of jail bait." He laughed. "How big are these beauties?"He turned her slightly so that the camera could catch her profile."I-I'm 34D," she stuttered."Fucking lovely," he sighed squeezing her hard.In the mirror she could see him standing behind her half naked figure. He was old, almost as old as her Father, but somehow that didn't matter. She. Mom said, "Would you like to know which one of you is mine by blood as well as by love?"I found my tongue, finally. "It doesn't matter. You will always be mom and dad will always be dad. We both love you." Io nodded as she slipped into my lap. She reached over and pulled mom beside us on the sofa. We all hugged, kissed, and cried. Tears were of joy and for a set of parents we had never known.Mom said, "I think you should know. I believe that it doesn't matter to the two of you except to know. Can you make yourself cum doing it like this?” “Yes.” “Take your finger s away now I just want to see what your cock looks like now.” I was throbbing now with my cock twitching as I took my fingers away so she could see. I was a deep crimson color and the head was bulging. “I want you to do something else for me now, O.K.?” “What do you want? She hesitated and then said, “I want you to stop touching your self…..can you do that?” “Yes I can ….. but…..” “Yes please …….. I just want to.
