I gasped in surprise and delight at the size of it! I slowly rubbedthe outline as his tongue continued to explore my mouth. Unable towait, I was soo... unbuckling his belt and unzipping his pants. I fishedaround inside of his pants and pulled out his fully erect penis,savoring the musky, male scent that arose from him. His cock was veryfat, my shiny red fingernail just barely touching my shiny redthumbnail. We watched the movie together, my head on his shoulder as Islowly jacked off his cock. Clark stepped in front of me with his erection pointed at me, pulled my towel open then pushed me back so I was lying with my ass on the edge of the cushion. I looked up at him as he put his hands on my knees and pushed them apart. No girl in high school hasn’t some knowledge or education about sex. Most of it comes from friends, movies, the street or gossip. but we all know something about the who, what, where and why of the facts of life. I wasn't completely naive about boys and girls so. "I could not hide the blush that coloured my face but I hoped that the swelling of my hard young cock, as I remembered watching her, was hidden by the shadow of the desk. The biscuit I had just bitten fell apart, showering my lap with crumbs. Mum tutted and leaned forward to brush the crumbs away with her hand. As she brushed, her hand pressed against the hardness of my young cock and she squeezed gently, feeling the outline through my jeans. All of the crumbs had been swept from my lap, but. So I slapped her harder."Yes, yes," she grunted, "across my tits too."She had never called her breasts tits before; I slapped her hard across her pert tits. Her hips took off, grinding themselves against me."Oh my god yes," she cried, so I hit her again.Her orgasm hit her hard then and it was the biggest I had ever seen her have."Oh my, she sighed, "that was nice."She opened her big blue eyes and smiled down at me. In all the confusion I hadn't actually come myself yet so she slid off my lap.
