Stop it!" Tom frantically reached back grabbing for Karen'shand. That was a mistake."Tom!" Jen's voice was sharp. "Let go of my sister."Tom realized w...hat he'd done and immediately dropped Karen's wrist. He'dgrabbed her purely out of instinct. Now he wished he hadn't. Oh pleasedon't spank me! Please!Luckily his quiet pleas were answered. Unfortunately they were answeredbecause Jen had another idea in mind."Tom," she said. "I expect you to behave. That means not grabbing at mysister. Or me. Do. At the time of senior year I had just turned 18 and Mrs. Jaymes was 36. I was on the high school baseball team and I was in pretty good shape. Not extremely built, but toned and a pretty good looking face. I had my fair share of girlfriends, but I had never actually had sex yet. The one thing that kept my confidence up, though, was my penis. I had measured it once, though I knew it was big I was curious to know how much bigger than the average size it was. At 18, I measured at 9 inches long. I sucked both her nipples and stroked er clit till she got close to cumming. Then stopped.'Baby noooo!''Patience honey. Patience'I started kissing down her belly. Soft quick kisses. I then moved over her pussy. Kissing it very gently. I opened my mouth and let my tongue take in her taste. Taking in her wetness. I sucked her juices as my fingers pulled on her nipples and squeezed her ass. I started licking her really fast. Upwards then downwards and sideways. Making sure I hit every part of. " As I approached, I could distinguish it better. She was saying "My arse, My arse!"I didn't go in. They were obviously screwing to the music, her and her new friends. Now and then I heard the blokes grunting appreciatively. It's hard to say how I felt. Her friends all knew too. I got very aroused, it was sick but horny. Somehow animal like in a strange way. Very rude, obscene even but earthy and sexual. I could hear the biggest guy with the shaved head, who had taken the mickey out of me when.
