[M] Full Marks (1/1)

[[As a request. Leeteuk is female in this story.]] Heechul was sitting in the classroom late. His teacher had asked him to stay behind to talk about his marks. If it had been anyone but his homeroom teacher, he would have said ‘fuck off’ and gone home. But his homeroom teacher was a babe. She was only in her early thirties and Heechul found that sexy as hell. He had trouble keeping his teen body from pumping blood down to his groin, leaving him hard every time she wore a pencil skirt and loose blouse. Heechul liked her in white the most, when the bright overhead lights showed off just enough of her bra to turn him on.Almost everything about her turned him on. Heechul liked to watch when her back was turned to the class, writing on the blackboard. He’d imagine walking in behind her, lifting her skirt and getting inside her while massaging her small tits. His friends had gotten sick of listening to him talk about her, so he’d kept his thoughts to himself until he was alone at night, overusing tissues.Confusion had taken over when Heechul had learned Park seonsangnim’s first name was Jungsu. It sounded too masculine for such a pretty face, topping a petite and tight body. A body Heechul wanted, needed, to see naked at some point. Since the name didn’t fit his fantasies, Heechul had come up with Leeteuk for her nickname, Teukie for short.The door to the classroom opened and Heechul watched as she walked in carrying a file against her chest. Her small breasts were squeezed against the file and catching Heechul’s attention more than the long legs inviting him to look up her body. Heechul had hit his growth spurt early and so even though Park seonsangnim was older than him he was already taller than her, if only by a few centimeters.Setting the file down on her desk, his teacher regarded him and Heechul tried, sincerely tried to keep his eyes on hers, but they kept sliding down to look at the lace pattern of her bra, showing through her white shirt.“Kim-ssi,” she addressed Heechul in her sexily soft voice, but he stopped paying attention after that, shifting his legs to hide the fact that he was now sporting a boner. Damn this woman for having so much power over him.Standing from her chair, his teacher came around her desk to sit on the front of it. Her small, soft hands were clasping the edges and Heechul couldn’t stop staring at them. “You haven’t been listening have you?” Park-ssi asked him. Heechul could only shake his head as he watched, his eyes slowly following her hands as they moved to her chest, holding the necklace that draped over her breasts. “What am I going to do with you?” She asked, smiling softly.Fuck me Heechul thought, grinning. “I’ll try harder?” He said as he leaned back in his chair, spreading his legs. The desk would hide his otherwise noticeable bulge.“Is that a promise?” Teukie asked, getting off her desk only to sit on the edge of his. “Because I’m not sure I can believe you.”Heechul had no idea why his teacher was so close to him now and he really wished he could pay attention to what she was saying, but he could only think of being inside her. Giving up holding back, Heechul lifted a hand and placed it on her stocking covered knee. “I can make you.” Heechul whispered.“What are you doing?” Teukie asked with a smile. She didn’t push Heechul away, instead leaning back on his desk and spreading her legs just slightly.“Applying myself?” Heechul grinned, sliding his hand up her inner thigh more, into her skirt.Leeteuk pushed his hand away and moved on the desk so she was facing him, a heeled foot on either side of his legs on his chair. “You think you can handle me?” She asked, leaning forward so her skirt rode up enough he could see to her panties.“I think I want to try,” Heechul looked between her legs, not caring that she watched him. He sat up more in his chair sliding both hands over her inner thighs toward her panties. His eyes flashed to hers as she clamped her legs down on his hands before he could touch her. The question about why she’d stopped him never got answered because Heechul didn’t get a chance to ask it, finding his teacher’s lips pressed against his own.Standing out of his chair as he kissed her eagerly, Heechul’s hands found their way to her chest. He squeezed her breasts the way he’d seen it done in every porn he’d watched and got harder when she moaned.Everything turned frantic then. Leeteuk got to Heechul’s pants, opening them quickly and Heechul tore at her blouse, popping buttons that landed on other desks in his desire for her tits. He cupped the small weight of one in his hand, jiggling it gently before leaning in to suck her nipple hard, flicking his tongue over it. Leeteuk gasped and slid her hand into his underwear, rubbing him slowly.Shuddering, Heechul couldn’t wait around with more foreplay. He tugged her by her arms to stand up, finding the zipper for her skirt. After it fell, he ripped at her stockings, tearing them on accident. She moaned and grabbed his head, kissing him hard. Heechul moaned as he yanked down her panties, forcing a hand between her legs to rub over her already wet clit. He’d never felt a girl as wet as she was and it turned him on as he slid a finger into her.Leeteuk moaned and clung to him, her legs shaking as he fingered her, his thumb pressed hard against her clit, rubbing. Licking her palm, Leeteuk rubbed over Heechul’s teenage erection again, needing him.Heechul quit feeling her insides and pushed her hand away from his penis. Kissing her deeply, he laid her down on the desk and shoved himself inside her, rocking his hips greedily. Leeteuk tucked her legs around his hips and pulled him in, wanting his aggressive and possessive, need fueled fuck. She moved with him, tightening her muscles around his erection as he rammed her.Inexperienced as he was, Heechul managed to last a few more minutes. He squeezed her breasts as she scratched patterns into his back. Sucking her nipples, he was so sure she’d cum and she gasped and shivered under him. Her thighs proved stronger than they looked as she clenched around him, forcing him to stay deep.Not able to keep up with her, Heechul came suddenly, gasping as his whole body tensed with the force of it.“Keep moving,” Leeteuk demanded near his ear and Heechul nodded, fucking her harder. He’d never felt a vaginal orgasm before and it was a whole lot better than he had expected. Warmth flooded over his erection completed with tightened muscles that clenched and unclenched so quickly he almost came in her again.They were breathing hard as Heechul pulled out, his cum following behind in a wet, white, trail on the desk between her legs. She stayed laying there, breasts out from a shirt half on her shoulders, stockings and panties hanging awkwardly off her ankles. Heechul wished he could take a picture, but he knew he’d keep the mental image forever.“Looks like I handled you,” Heechul said softly, pulling his pants back on.Leeteuk laughed softly as she finally sat up, putting her clothes back on. “Full marks.”
