I couldn't help it, I let out a scream as a very intense orgasm took me by storm, almost making me lose consciousness. To top it off I could feel a ho... jet of cream squirt inside me as he to came with a caveman type grunt, himself unable to hold back. “Lie down on the bed on your back Jan with your legs apart” I was instructed by Zak. As I did so I could see out of the corner of my eye that Natalie was attaching a strap-on to her self. Zak then manoeuvred into position to capture for all of. .. my son’s cock. It’s so wrong, but I can’t stop it. The fact that you came out of this pussy over eighteen years ago makes it so much more exciting. That is crazy I know.”I opened my mouth but nothing came out. There was nothing left to say. I watched as my mother slowly lowered her hips until the head of my cock was touching her already wet pussy. Then she moved lower, taking the head into her. Her mouth opened as she stared into my eyes.“Oh, Mom,” I gasped as she pushed lower. Inch by inch. I must admit i was in the moment and didn't hear Tayna call from up stairs but certainly heard her when she gasped ' Oh Ben what are you doing love'. In a bit of a panic and embarrassment i dropped her panties back into the basket and pushed my raging hard cock back into my jeans. 'Well ?' Tanya asked quite strenly. I looked @ her and replied ' i couldn't help myself Tanya, i noticed your panties before moving stuff around and was i perving on you when you where down here before.' 'I noticed. As she teeters back and forth, raising one foot then the other exposing the heels of her feet, still tender without any sign of the grainy calluses a girl older than her may have. Flowing smoothly into ankles her calves are quite balanced. The muscles are there but undetectable in there uniform elegance. Her knees, only a girl of her age can have such a refined look to them. But her thighs, they impress, compelling but gracious. She is one of few that need not wear nylons to hide any.
