Biology Class [m/f]

> One of the first stories I wrote. Bit clunky but I think it’s OK, would love some feedback…

The bell rang out over the yard, and we all started to trek back into school after lunch. Damn, I hated biology lessons, and we had double biology all afternoon. Still, at least in biology I got to sit next to Lucy. Fuck, but Lucy was dangerously hot – cute little blonde with sapphire-blue eyes that could make you weak at the knees from the other side of the room. The way she wore her uniform was almost criminal – little pleated skirt that swirled out every time she turned, every time threatening to flash a little knicker, but never quite delivering. Tight little white shirt on top, which her pert young breasts were constantly straining against. Honestly, the girl was a danger to my heart – my blood pressure, especially in one part of me, went through the roof every time she walked into the room.

Walking into the room was just what she was doing. Strolling lightly over to me with her usual fuck-me grin on her face. If you looked up ‘cocktease’ in a dictionary, there’d be a picture of Lucy right there – probably biting her lower lip in that way she always did when she looked over at you.

“Hiya,” she breezed, pulling up a chair and sitting down next to me, her delicious scent wafting into me and making my heart beat a little faster. Boy, had I lucked out when they did the seating for this class – back row, by the window, two-person table with the fittest girl in the year. Almost made biology bearable!

“Quiet please, settle down now,” Mrs Gladstone walked in and so the two hours of boredom began.. “Turn your textbooks to page 76 please,” she intoned in her monotone voice. We obliged, looking down at a page of diagrams of cells with a sinking heart. Just as I was wondering how I was going to keep my eyes open for the next hour, Lucy tugged at my sleeve..

“Hey, look at this,” she whispered, and pointed at her textbook. It was open at the ‘Human Reproduction’ page, complete with photos – here a naked girl, there an erect penis, on the other page, a couple having quite clinical-looking sex. “I wish we were studying this!”, Lucy whispered into my ear as I felt her hand slip onto my thigh. Fuck, what was she doing – sure, these science lab benches had cupboards on one side, so nobody could see, but what was such a gorgeous girl doing touching my leg!

“I bet the practical lessons would be fun,” Lucy said, and moved her hand up towards my crotch. I was getting excited now, my cock getting hard inside my pants, and Lucy was nearly close enough to feel that. I jerked up in my seat as her hand slid over my growing erection, and an electric shock ran up my spine in response. With surprising dexterity, Lucy unzipped my regulation black school trousers, and reached in to pull my tight white boxers aside. My now hard cock sprang out, glad to be relieved from the pressure of underwear. Her eyes gleamed as she wrapped her hand around me, “nice cock you’ve got here” she said quietly, grinning. I was rendered silent from a combination of surprise and pleasure, and she started to slide her hand up and down my shaft.

To outside appearance, Lucy appeared to be paying attention to Mrs Gladstone, while under the table she was stroking up and down my throbbing shaft, running her fingers over me, wanking me like a pro. I looked over at her, and could see she was getting horny too – her nipples were starting to push against her little white shirt, and her face was getting a little flushed too. I looked down, and she’d parted her legs a little – I was sure I could smell the sweet musky smell of a wet pussy too. All this just made me hornier, and made it harder and harder to keep myself from crying out as Lucy’s hand carried on wanking my cock, her small, perfect hand gripping me just hard enough to make me almost cum right away.

Lucy leaned over again, her wet, red lips next to my ear – “I want you to cum for me,” she whispered into my ear, “I want to feel your cum running over my hands.”

This was just too much, as her hand moved faster and faster, I stifled a moan as best I could as I started to cum, shooting my load under the table in a class full of people. I’m sure someone must have heard me, but nobody turned around. Lucy grinned that grin that in years to come would get her all the free drinks she wanted, and pulled her hand out from under the table. Looking into my eyes the whole time, she slowly sucked each finger clean before reaching over and taking my hand, guiding it under the table and up under her tiny skirt where I could feel her panties were soaking wet. “Time for you to return the favour,” she said.

I placed my hand flat against the damp cotton for a moment, curling my fingers around to cover as much of her as I could, feeling the heat of her against my palm and heard Lucy gasp a little at my touch. I looked around to make sure nobody could see me, and started to slowly and gently rub my hand over her tight white panties. Lucy rocked her hips to push herself harder against me and whispered, “I want your fingers inside me.”

Moving my hand up and reaching down under the band around the top of those painfully sexy knickers, I pushed them down Lucy’s thighs a little way and I slid my fingers over her pussy, feeling slick, smooth skin as I did so. Lucy’s wetness covered my fingers, hot and wet and slippery and wonderful. Guiding my finger down between her pussy lips, I felt her clit hard beneath my fingertips, and stopped to linger there for a while, circling my finger around and hearing the sharp intake of breath next to me as I did so. Glancing over I could see her beautiful face slightly flushed, biting her lower lip as she tried to not make a sound while I massaged her in the busy classroom.

Looking down, I could see that under Lucy’s close-fitting white shirt her nipples were starting to push forward, creating incredibly erotic dark shadows against the smooth cotton – at that sight, and the sensation of her shaved pussy, wet around my fingers, I could feel my cock starting to get hard again under the table all over again.

Pushing my hand down from Lucy’s hard clit, I curled one of my fingers around to slip it slowly into her pussy, tight and wet and hot and exciting around me. Lucy leaned forward a little to take hold of the table’s edge, her knuckles white as she grasped hard and clenched her teeth at the pleasure running through her. First one finger, then another, then a third I pushed inside her, my palm still stimulating her clit as I probed deep inside her. Lucy’s slightly breathless whisper came again in my ear – “Fuuucck that’s so good, keep doing that, I’m going to cum any minute…”

I drove my fingers into her faster and harder, sure that the wet sounds coming from under Lucy’s tiny skirt were loud enough to be heard by the rest of the class, sure that her quiet but insistent panting was going to give us away – her with my hand in her soaking wet panties, me with my cock out, it’s rock hard length bobbing around under the table, cum still dripping. The idea of getting caught set my heart racing even faster – what if the girls on the table in front turned around? They’d see everything! What if the teacher caught us and made us stand up in front of everyone – Lucy with her panties halfway down her legs, my hard cock out there for everyone to see.. God, it made me so hard it almost hurt.

All the while thinking this, I kept pleasuring Lucy, who was clearly on the edge of a huge orgasm. She could barely contain a cry of ecstasy as her hot pussy began to pulse around my hand. “GNnnnnnnnnnaaaaaaaaaahhhh,” she exclaimed as quietly as she could, her hand reaching over to grab at my thigh as she shook in her chair, my hand and her white cotton panties drenched as she came, hard.

“Jesus that’s good,” she whispered to me as I withdrew my fingers from her, lifting my hand to my mouth so I could suck the delicious taste of her from me. She watched for a moment, smiling, until – with an incredibly sexy wiggle of her hip – she pushed her knickers the rest of the way down her legs. She picked them up and slipped the damp white cotton into my pocket, “Present for you,” she whispered, “to remind you of me.”

Before I could reply I heard the bell ring and Lucy jumped up along with the rest of the class, grabbing her bag and winking at me as she did – “See you next time”, that filthy, knowing grin of hers getting another outing and causing my cock to twitch again with desire as she wandered jauntily away, whispering and giggling with her friends as she did.

I started to put my cock back in my trousers – easier said than done because it was still so hard, desperate for attention after what had just happened – I was going straight to the toilets for some “me time” after this lesson, that was for sure. Looking up I spotted one of the girls on the table in front of us was still there, putting her books away. She wasn’t one of the “cool” crowd but a quiet, faintly mousey girl who I’d always secretly thought was pretty hot. She had a nervous grin on her face, flushed a little red with what I assumed was embarrassment as she stood up and looked over at me. “I heard all of that. Can I sit on yours and Lucy’s table next week?”
