This is probably one of the more straightforward, low character development stories I've written in a while. Despite being in high school, all characters are over 18.
"Fine, I'll go first. Not like you two haven't seen it before."
With that, John's girlfriend Katy stripped off her clothes. Her body was great, without any particular part of her that stuck out. She was trim but not muscular, so everything about her was curves and smooth skin. Her 34B breasts were perky, not even folding at the bottom, with small hard nipples. She rarely bothered to do anything fancy with her dirty blonde hair, which she now had loose hanging down to her shoulders.
John looked over at Noah. They were both in the same friend group at school, firmly entrenched as part of the "harmless geeks;" they liked movies but didn't want to make them, had high-powered gaming computers but couldn't program or hack anything, and good students but not smart enough to be in AP classes. They had some girls in their orbit, mostly from the track and drama crowd. John and Noah weren't close friends, but they were certainly getting closer tonight.
Technically Noah was Katy's ex, but he had broke it off with her after two weeks, claiming she was "too much." She'd moved on to John after a month or so, dropping hints as subtle as a train wreck. Katy was definitely into sex. Kind of wild sex. It had only taken two months of dating her before she started to suggest stuff John had only seen or heard about in porn. Where rumor had him believing most of the girls in his class waited up to two months before sex was on the table, Katy had used it to mark their second date. Her one month anniversary present to him had been her ass. They'd had quickies in every room of the school where it was feasible, and some that were really close calls. She'd given him a blowjob on the 50 yard line. She owned a bunch of silk scarves that spent more time around her bedframe, wrists, and ankles than her neck. Then, more than six months in, she'd come to him and said, "I want to have an orgy."
So there they were, in Noah's parents' pool house, stripping down. His parents' house was large but not overly so, but the in-ground pool and spacious pool house pushed it a step above most other places. Fortunately it also had a high fence. His parents were gone for the weekend on a trip of some kind.
They sat, looking at the table, nursing some beers in plastic cups, and trying to avoid making eye contact while Katy waited by the door. As she'd explained to John several times, a threesome was not an orgy. Her threshold was five. Five would have been easy to hit just asking his guy friends, but she said for it to be an orgy it had to have multiple girls too. He knew it wouldn't take much to convince his guy friends to join in, but he had no idea how you convince high school girls to be in an orgy. His thought at the time was that none of the high school girls he knew would agree to it.
He'd been wrong.
There was a knock on the windowed door of the pool house and Holly was greeted by a fully nude Katy when the door opened. Holly stopped to look at her best friend.
"You going back on your 'no nookie with Katy' idea?" Katy teased after Holly had been looking for a while.
"You wish," Holly said.
"Strip," Katy said.
"What?"
"Everyone kept being paranoid about phones and cameras and shit. So you don't get in unless you're naked. That's the whole point of the night anyway, so may as well start now. Clothes in that bin."
A large plastic trash bin sat next to the door, but it had no bag. Holly peeked in and just saw a pile of clothes, a pale green bra on the top of the pile. Glaring at Katy, she added her own clothes.
John and Noah stared as Holly walked in, naked. She had more weight on her shorter frame, but again thanks to being 18 it was going to all the right places. Her hips flared out from her waist, forming a perfect hourglass above her soft legs. Her breasts outstripped Katy's, still teardrops but swinging pendulously as she walked, the nipples already hard and making the larger aureole tent into cones. She mostly kept her legs together as she walked, but the completely bare skin between her legs still drew their gazes. She had a nervous smile on, but seemed to get a little more confident as the boys stared at her.
"Can I have some of that?" she asked, gesturing to the beer the boys had poured into Solo cups. Both of them nearly knocked it over getting her some. She took it and sat next to John.
Holly was practically virginal compared to Katy, but almost everyone was. She'd only had one steady boyfriend anyone knew of; John's best friend Phil. They'd broke it off amicably without a big blowup or nasty rumors, but Phil had never really told him what killed their relationship. John only got more nervous as she sat next to him; when Katy had approached her, Holly had said she was only going to join in if she didn't have to touch Katy, she got to fuck John first, and she got to borrow John specifically for a week after, whenever she wanted. Katy had thought the idea of "loaning out" her boyfriend was hot. John wasn't so sure.
"Fuck, is this happening?" Noah asked.
"Don't worry Noah," Holly said, "This'll be a night to remember."
Henry and Phil showed up together. Phil, John's best friend, had a thoroughly average body, including his penis. He was a stereotypical "nice geek" who everyone mostly ignored. Henry, on the other hand, had the distinction of being one of the few black students in their school. His build was more athletic; he wasn't sporting a six pack, but when he moved you could see muscles. He also somewhat upheld the stereotypes of porn; while he wasn't packing a monster downstairs, a quick look showed he was above average.
They all heard the exclamations of shock as Katy greeted them nude at the door. They had no objections to stripping and came in quickly. All the guys made sure to hold strict eye contact, though darting glances compared equipment quickly, all of them unremarkable but for Henry's slightly larger unit. Holly seemed to notice that and had no problem considering it for a while, accepting the lingering stares of the guys in return.
"What up, fuckers?" sounded from the doorway a few minutes later as Marissa made her entrance. Her waify body was a stark contrast to Holly's, with subtler curves, visible ribs and hips, and barely-there, conical breasts topped with large pink nipples. She seemed to revel in the guys' stares and sat cross-legged on an ottoman, baring her smooth hairless mound for anyone to see, and then talking to Holly, acting nonchalant about it. Holly's replies were less carefree but she stared down Marissa, recognizing the nervousness in the thinner girl's eyes.
Marissa was the alternative girl who sometimes seemed to be part of their friend group and sometimes hung out with others. Holly had agreed but determined she wasn't going to be the only other girl there; she didn't want to fend off three guys at once while Katy got spitroasted, and she wasn't into multiple guys at once. She'd conned Marissa into showing up by turning it into a dare. Marissa was the type who liked to embarrass popular girls by grilling them in public about their sex lives when they dropped coy hints about their boyfriends. She also claimed to have wide-ranging experience. Holly basically told her to put up or face the wrath of the high school rumor mill when she outed her for backing down. Marissa had other conditions beyond that, though.
What little conversation there was paused when Katy let out an excited squeal from the doorway. A minute later she led in a tall, decently built guy with brown hair and a nervous smile. His gaze skimmed over the guys before locking in on Marissa and Holly.
"Hey everyone, this is Steve. He works with me at the Starbucks," Katy said.
"And how'd he get an invite?" Marissa asked. She sounded put out but her eyes also roamed the fit body of the towering man.
"Because he got us this," Katy said, lofting a bottle of Jose Cuervo.
"Oh fuck yeah, he's in. I'll even do him first just for that," Marissa said, winking at the guy. He smiled but also blushed a bit.
"Cups," Noah said, pulling more out and prompting John to help him.
They all helped in the end, laying the cups out on the low coffee table, until Noah dropped one and said, "Holy fuck." They all turned and stared, even Holly.
