As Coach Marlin looked at the naked girl in front of him, he began once again to think of her as a student. He was getting ready, for the first time, to violate the cardinal rule of teaching. He knew there was no stopping now and rationalized that, after all, she had been the seductress. But her small, 26 inch waste, her little developing titties, all made her look so young. Hell at thirteen, she was young. Brittany turned to the window now to see Justin and Todd, both fully clothed, comb their hair and adjust their clothing in front of the mirror. It was if they were looking straight at her, naked and everything. She was hoping in her mind that the coach was serious about arranging for Todd to fuck her. As she stood facing the window, the coach positioned himself behind her. She put her hands on the window sill, leaning into it, her face now only inches from the boys grooming on the other side ofthe glass. Behind them, more boys were drying off. The coach used one leg to move her feet apart and then gripped his stiff monster cock with one hand, guiding it to the slippery hole that he had fingered moments before. Brittany felt the head of it as it completely covered her hole and even expanded beyond the lips of her cunt. It took several stabs, but the prelubricated cunt made way for the massive cock. After the huge head had popped inside, the thick shaft followed more easily. Soon Brittany was full as she had never been before. Todd turned to leave. Another boy, a seventh-grade brother of one of her friends, took his place and began drying with a towel. That was all it took to make her cum again as the coach now steadily drove his adult sized cock up her little girl sized cunt. The increased fluid now made it easier for the cock to fulfil it's mission and the coach dutifully fucked the little girl. He looked down in lust at her bare white ass which was now squashed up against his hairy stomach. Her legs had went numb when she started to cum and the man was now holding her off the floor as he held onto the window sill. "Fuck me good, screw me, oh I'm cumming again, please get Todd to fuck me too! Ohhhhhhhhh! Ungh. Ungh." Brittany began a series of obscene grunts as the coach repeatedly drove his cock deep into her, impacting the back wall of her cunt with regular precision. He vulgar words and obscene grunts took their toll and he felt the familiar rising of the orgasm in his balls. It had been at least two weeks since he had cum and he new there was plenty of sperm built up in his balls. he also came to his senses long enough to to realize that it would be very easy to get this 13 year old student pregnant if he uploaded it all inside of her. It took all the discipline that he had, but he did it. Brittany, still breathless from her most recent orgasm, panted, "What's wrong, Mr. Marlin? "Nothing, dear. Come here," he replied. He picked the girl up with both hands and set her on the desk. Gently, he laid her down on her back. He placed one hand over her sloppy twat and sank a finger deep inside her. With the other, he stroked his cock in a familiar method that he knew would cause him to erupt. He looked down a Brittany, her smooth, flat stomach adorned by her perfect little navel; her little titties flat against her chest. She smiled as she reached up and gently caressed his balls while he jacked of, just as she did for her brother on many occasions. The orgasm caught the coach by surprise. His first slippery wad impacted her cunt and she immediately started rubbing it in. The next made a river across her stomach and yet another across her tits. Still holding his balls, Brittany gently guided him so that the next several wads impacted her face, sticking in her hair, across her eyes, and finally in her mouth. She continued to kneadhis balls as the gooey mess dripped down her face. She looked up at him and gave him a sexy smile through her sperm covered lips. His cock, now empty was still half hard. He pulled her around so that her ass was off the desk and took her legs straight up with one tennis shoe on each shoulder. He literally stuffed his half hard prick into her wet, slippery hole and began pumping. As Brittany licked her sperm covered lips, he chanted softly "Cum again, you little slut. Fuck me, you jizzy little teenaged whore." To his surprise, his own words and the sight of Brittany's pretty little teenage face covered with his dripping semen caused him to get completely hard again. Brittany went into yet another orgasm but this time used a trick that had seemed to work on her brother. She lubricated one finger and pushed it into the man's as. As she spasamed in orgasm, she forcefully massaged his prostrate. The coach unleashed another load of hot sperm in the only place on her body he hadn't already covered -- inside her cunt. The feeling of filling the child with his stuff again made the coach forget the consequences and he continued to pound the little girl mercilessly as she milked his cock with her pussy. She pulled her finger out of his ass as he continued to cum which even intensified the sensation more. Brittany continued to look up at him, beaming her sexy smile as his cock, once again emptied, began to go limp. As he pulled it out of her, a wad of his semen gushed out too. It dripped down the crack of her tiny white ass and formed a pool on the desk top. A plopping noise accompanied the exit of the head of his cock from her cum soaked hole. "Brittany," he said to her as he caught his breath, "you are by far the very best fuck I have ever had in my entire life. You're Great!" "You are good too, Mr. Marlin. I would like to do this again." "Me too, but we've really gotta be careful. You understand why, don't you?" he asked. "Yes. I do. And I won't tell anyone. I promise." Reaching for a stack of towels on top of a book shelf in the office, he tossed her one. "Shower up, young lady," he told her. Brittany looked quizzically at the window where the last of the boys were getting dressed and back at him. "You can shower with the boys if you really want to, Miss Kramer, but I would suggest my private shower over there," he said, pointing to a small door. As she turned to go wash the sticky goo off of her body, he grabbed her gently by the arm and looked her lovingly in the eye. "I mean it, you were great!"
