Everyone in this story is over the age of 18.
***
For years, this was her fantasy. Mellie, now 18, first discovered it at 2 am on one of her late night explorations through the internet and it turned her on more than anything she'd ever come across—or ever would. But as a minor, it seemed incredibly stupid to act out on it. Now that she'd grown up, it was still incredibly stupid, just slightly more legal.
So there she stood, looking at her small and slender frame in the mirror, nerves buzzing. She slowly went down her body, starting with her auburn hair—the top pulled back into a braid, the rest laying on her shoulders—then moving to her freckled cheeks and green eyes, a nervous half-smile showing her white teeth and melding in with her pale face. Shifting from foot to foot, she saw her green cardigan covering her shoulders, matched up with a white tanktop. Her boobs weren't anything special, barely graduating into b cups, but what stood out in her excited state were the prominent nipples. Anyone glancing at her would be able to see her nipples, and thinking about it there brought Mellie's hand closer to her crotch, but she managed to hold off as her eyes moved past those prominent buttons to her slender waist and the nice green skirt with flowers embroidered in gold across it. It hung loosely to her, just enough to capture her hips as it went down to her ankles.
The outfit wasn't all too special for Mellie, she'd gained a reputation for looking like a 1950s nurse, but it was what she lacked underneath it that brought her so much excitement. With no bra, warning lights would signal for anyone who passed her, but that was just the beginning of the story. She wasn't wearing any panties, which shouldn't be a problem thanks to the long skirt, but she also wore her buttplug, it's bejeweled bottom sparkling when Mellie lifted her skirt to check out her ass one last time.
The buttplug wasn't new, she'd worn it at home now for years after she discovered anal. She'd even worn it to sleep, her record for length was 16 hours, but was new—like the rest—was wearing it out in public.
One last smile, one last look at her new look, she shrugged and grabbed her backpack. It was going to be a fun day and when she was done, she'd masturbate to the biggest orgasm she'd ever had. Her mom wasn't in the kitchen when she marched down the stairs, her shift at the hospital always saw to that. Patting her golden retriever on the head, she walked over to her pickup and climbed in, feeling the buttplug press against her insides and the wetness that came from pussy stick her thighs together.
Walking to her first class of the day was an entirely different story than walking out of her house. From the second she got out of her pickup, eyes were on her. Boys adjusted their pants and girls murmured, but all through it Mellie held her head high as her arousal skyrocketed. Going through the front doors, the teacher on duty—Mr. Jordan—cleared his throat. So did Sam, the 18 year old boy she sat next to for her first class of the day, chemistry.
Everything was going perfect for Mellie on her expedition, and even as her cheeks turned the same color as her hair from the mixture of arousal and embarrassment she smiled through it all.
"Alright students, we're doing a lab today," Mrs. Kortman started the class with. "Work with your partner, I'll pass out the lab guide and resources. If you have any questions, feel free to ask. Remember to wear lab goggles."
Mellie and Sam got up and Sam reached out to read the lab guide first, leaving Mellie having to lean up close to him to read the report, her right boob pressing up against his ribs. She was confident he could feel her hard nipple mixed in with the softness of her tit and her confidence was rewarded when she saw him move a hand off the report and down to adjust his pants.
"So what materials do we need?" Mellie said, taking the prerogative to go and get things started.
"Um, we'll need a beaker and a hot plate, along with some of the chemicals that Mrs. Kortman has up there," Sam said, nodding towards the throng of students at the back of the classroom.
Mellie thought for a second, her adrenaline rushing after her first contact of the day, and did something bold that she'd never thought of doing before, "I'll stay here while everyone's all grouped together up there and wait for it to be less crowded. Here, though, let me see that paper." She reached across with her right hand, making sure to bring it up across the front of his body and having her forearm brush past his crotch. She wasn't that surprised to feel a hard-ish knob down there, but she was surprised at how horny the thought of it made her.
Sam was an attractive guy, he had nice hair and a sturdy frame, his strong chin matched his bright blue eyes. He was about 12 inches taller than her 5-feet and always found himself staring down at her while she had to look up at him, which as she thought about the connotations of that in terms of sex turned her on even more. Her mind ran away with the image of her, on her knees, looking up into those steely eyes, her mouth around that hard bulge he hid in his pants.
"Are you going to get the supplies?" Sam asked, breaking Mellie out of her routine.
The rest of the class was a flirtatious blur as the two acted in ways they never had before. Mellie started out by finding any reason to make contact with her lab partner—grabbing his arm, pressing into his back to watch the experiment—and soon Sam caught on, returning the favor.
As the class was coming to a close, Sam made his final play. Mellie was holding a crystal in her tongs over a beaker filled with acid, and asked, "What does the lab say I do with this?"
Sam moved from reading the lab and placed himself behind Mellie, his crotch matching up perfectly with Mellie's ass, and leaned over, pressing himself into her as he said, "I think you're supposed to insert it."
Mellie let out a slight moan as she followed his direction, his still-hard cock had pressed right into her buttplug as he said that, giving a faint feeling of him inserting himself in her ass. Sam, meanwhile, had a different thought going through his head—what was that hard thing he felt in her ass?
After packing things up and "accidentally" bumping into each other a couple more times, Sam told her before heading out, "I think I'm going to need help with this lab report, we should probably meet sometime to go through it."
"Yeah for sure, here's my number," Mellie said as she took his phone, "Text me if you need anything."
Going to her next class, Mellie came down from the high of what just happened. What did just happen? Mellie had flirted with Sam. Sam, the baseball player. The cool kid, the jock. And now he had her number. Just in time, her phone buzzed with a message, "Hey, this is Sam. Just so you have my number."
"Ughhh, what now!" she mumbled out loud, to no one in particular.
The rest of her morning went as she had expected, with no more flirtatious encounters with boys she'd never flirted with before. Eyes were on her, but her mind was elsewhere, not because of her tits being out or the buttplug in her ass but because of Sam. Because of goddamn Sam.
When she walked into the cafeteria, she saw him across the room. Even worse, they made eye contact, forcing an awkward smile and wave from both parties. Less than a minute later, she got a text from him, "Hey, I'm going to the chem lab to work on chemistry again if you want to help."
Shit shit, fuck shit fuck, Mellie grabbed her tray and made excuses to her friends, "I've gotta work on my chem lab with my partner... I know, I know, I'm sorry... We'll talk after school... Bye bye."
It was just the two of them in the chem room when she got there and seeing Sam, his laptop open and papers around him as he worked on chem had a weird and new effect on her. There were butterflies in her stomach and she nearly fainted when he looked up and smiled at her. Here she was: her tits out and a buttplug in her underwear-less ass, falling hard for this man who isn't even close to her same friend circle, who she'd never even though of sexually before now.
"Thanks for coming," he said with a smile.
"I needed to help your sorry soul, couldn't watch you suffer through this alone," she replied, having no idea where her coyness came from. "How much have you done without me?"
"Not too much, I've been distracted a lot."
"Oh, damn. Well maybe I can help you focus," Mellie said, thinking he was still serious about doing chemistry homework. By now, she'd set her stuff down next to him, sitting closer than usual—a slight nudge out by her right hand and she'd be holding his hand.
There were 50 minutes during lunch period and while Mellie's head was in the clouds, Sam had a plan. "Well you see," he said getting up and moving towards the door. "You're the thing that's got me distracted."
Sam locked the door. Having read through stories online and watched hundreds of hours of porno, Mellie's switch finally turned in her brain. She'd been turned on all day parading around, and now here she was locked in a school room with a boy 12 inches taller than her who could easily over power her.
She stayed in her seat, hesitating on how to play this, as he moved back towards where they were sitting. He walked around behind her, his hand going through her hair, and Mellie went into autopilot as he lingered for half a second too long next to her chair. She rocketed up, pressing herself against him and reaching up with her hands to his face on her toes.
Sam leaned down to meet her, his arm helping to lift her up with the small of her back while the other embraced her face. The two kissed for the first time, and that kissed slowly became something more passionate. Tongues started entwining and hands started moving until Sam couldn't take leaning down to kiss her anymore. He lifted her up by her hips while their mouths still embraced and placed her on the table, evening the pair's height.
Mellie responded by wrapping her legs around his waist and squeezing him to come as close as possible to him. Her hands, meanwhile, reached down underneath his shirt and paraded across his bare back, eventually breaking the kiss for the first time to pull it off. What she saw took her breath away, his body was toned and bronzed, slightly glimmering from the sweat gathered while making out.
Sam smiled and discarded her cardigan, leaving her in just a white spaghetti strap tank top—for half a second. The straps came off and her shirt was pulled down just past her bare tits. He, for the first time, saw that the freckles on Mellie's chest didn't end where the clothes began, and leaned down to take one of her bared breasts into her mouth as she arched her back. When his tongue first circled her nipple she let out a slight moan, which quickly turned into constant moaning.
This position only lasted a few minutes before Mellie broke it off, pushing him away from the counter so she could get off and drop to her knees. His belt was quickly undone, so too was his zipper, and out sprung the hard knob that started this whole thing. It wasn't small, either. At 7.5" it was bigger than either of the two she'd sucked before, but that didn't stop her from grabbing the balls and licking up and down his shaft. With it finally hardened and the shaft properly lubed, she took the tip into her mouth, leaving her left hand to play with the balls while her right stroked the shaft.
Trying to be a gentleman while getting his dick sucked, Sam grabbed up Mellie's excess hair to keep it away from her mouth. He watched as the pale face bobbed up and down his circumcised shaft and smiled, this was not how he envisioned his day going. And then he heard the doorknob rattle and panic spread through him before he remembered the door was locked.
