She was about thirty-something but looked much younger. She had a cheerleader-like body, standing about five foot two and weighing a tad over one hund...ed. She is what we call a “spinner”- that type of girl that gets on top of a guy and simply spins around in ecstasy and pure sexual pleasure.For the most part, Nikki, Greg and I had a very platonic relationship. I had caught Nikki staring at me during a summer pool party, and I teasingly told her that if Greg ever decided to dump her, I’d be her. Nope. Not one day. Thankfully, the next day was a blur. Helping customers load huge television sets and costly computer set ups into their enormous cars and SUVs, settling complaints from lippy college girls who acted as if they totally understood all the fine points of gadgets when he knew they’d be back in an hour with questions, or placating disgruntled grandparents concerning the incorrect game they’d purchased for their spoiled grandchildren. By the time lunch rolled around on that. 'That was it' I thought, 4A boys were due there first period and the caretaker was locking the door to the girl's changing room. I guessed that he had to go there in the middle of each unoccupied period and lock / unlock the appropriate shower room doors. 'Yes' I thought, 'I'm coming back at lunchtime.'The corridors were deserted and I easily managed to get to the bike sheds and leave by the side entrance. As I pedalled home, standing on the pedals, I wished that Jon hadn't bought me the. Or so I was expecting… Instead, I heard the door tap against its frame softly. Today I could hear her sighs as she undressed herself. My eyes closed as I pictured her soft hands unclasping her lace decorated bra from her milk-white breasts, caressing the swells as the cloth fell away from them. Her hands teasing her pink nipples were like a video playing on the backs of my eyelids. I didnt have to open my eyes to see that my cock had begun to harden. The sharp gasp I heard from down the hall.
