"I'm really sorry, Kev! Derek stopped by the office to surprise me with a night out, and I totally spaced on our plans."
Kevin was disappointed, but honestly, he had seen it coming. He and Emily had been best friends ever since they met in freshman year of high school. They bonded quickly over their shared love of cheesy sci-fi shows and point-and-click adventure games, and had been pretty much inseparable from that point on. They had even chosen to go to the same college, and stayed best friends all throughout.
They spent so much time together that all their other friends pretty much assumed they were dating, even though they never did. Kevin did ask her out once, a couple of years into their friendship, only to be rejected.
Not that he minded too much. The sting of rejection hurt but the friendship was too important to him to lose, so he decided to do his best to move past it. And he managed to, mostly. But there were still times, like when she laughed particularly hard at one of his jokes, or when she would hug him just a bit tighter than usual after they hadn't seen each other for a while, that he would feel that attraction pull at him once more.
But over the last few years, they had started to drift apart. There was no big fight or anything, they just started spending less and less time together in the way that people do sometimes as they get older.
Emily's job kept her particularly busy. Her background was in chemistry, and she worked in R&D for a big booze company, trying to come up with the next big trendy alcoholic beverage. Kevin knew that her latest project had to do with creating some kind of compound that would give people more energy or something like that, so they would be able to stay out partying and drinking for longer.
He had heard more than a few of her rants about unsuccessful tests and weird responses from their rat tests, and how she had to spend a ton of sleepless nights at the office trying to perfect the formula. Unbeknownst to Kevin, she had even started taking some of her work home with her, so she could keep fiddling and running tests out of the office.
When she first started working there, Kevin almost swore off drinking entirely when she would tell him about all the weird shit they put in alcohol sometimes. Preservatives made from fish goo, and that kind of thing. But a few free samples and early test bottles put a stop to that quickly.
This is why Kevin was really excited when she wanted to hang out on one of her rare nights off. They made plans to watch a movie on Netflix, the latest in one of their favorite sci-fi series that they were too busy to watch when it was out in theaters. And why he was just as bummed now that she had canceled on him.
Still, Kevin could tell that she did really feel bad about leaving him out in the cold. Plus, he knew how hard a time Emily had had with dating recently, and wanted her to have the best chance she could finding someone good, so he couldn't find it in himself to stay mad at her for long.
"Alright, Em. Don't worry about it," he said "I should be able to make the next train home anyway."
"Train?" Emily asked. "Oh shoot, are you already at my place?"
"I mean we agreed to meet there like half an hour ago so..."
"Crap. You're right, I'm really sorry again. Tell you what. Drink my booze, raid my fridge, just chill for a bit. There's a key under the mat, just chill at my place for a bit before you head back. You can even watch the movie without me. I don't think I'll be back at my place anytime soon."
"So you abandon me
and
you're the only one of us that gets to have sex tonight?" Kevin said, already unlocking the door with Emily's spare key.
Kevin loved that Emily was comfortable enough with him that she didn't shy away from talking about her sex life. But imagining him longtime best friend and secret crush getting fucked by some confident, muscled-up alpha male hurt just a bit.
That was always Emily's type, and Derek fit that to a tee. Kevin wondered. If he could have just been more like Derek: more confident, more assertive; could he be the one out with Emily tonight? The one who would get to go home with her, to get to have sex with her?
"Hey man, the night is young. Just don't let any randos into my place," she said.
"Fine, but don't expect any of your fancy liquor to be left," Kevin replied.
"Hah, fair enough. Thanks, for being so cool about this, Kev. I owe you one."
"No worries, Em. Have a good night."
Kevin hung up and headed straight for the fridge. Opening it, he found a shelf full of beers he had never seen in his life, each with its own fancy label. Some didn't even have actual labels, just strips of tape written on with marker.
"Oh yeah, it's early access beer time," Kevin said. Emily had let him taste some of these test beers before, even if she wasn't technically allowed to at work. Usually, they weren't that great just yet but he loved being able to say he tried the next big trendy beer before anyone else. But Kevin took a sip bottle labeled "TEST 1" and found it was the best beer he had ever tasted.
He was just going to nurse it while he looked for something to eat, but before he knew it, he had downed the whole bottle. There was just a hint of some kind of spicy flavor that he couldn't get enough of.
"Damn," Kevin said to himself. "Gotta tell Emily that one's a winner."
Having finished his first drink so quickly, Kevin decided to sit down and figure out what he would have for dinner before opening another. Walking over to the couch and TV, he started to feel a bit warm. That was weird, since it was a pretty cold night and Emily generally liked to keep her apartment a bit chilly, but he figured it was just the alcohol.
Settling into Emily's couch, Kevin noticed something on the coffee table that hadn't been there the last time he was over: A picture of Derek and Emily on a hike.
"They've been dating for like a month, and he's already in a framed picture? Guess they're pretty serious," Kevin thought out loud. Then again, he could see why. He was jacked, successful, and a little bit cocky, just like Emily liked. A lot of the time, this ended up with her dating some asshole jock for a few weeks then dumping him when the excitement wore off.
But the one time they had met, Kevin learned Derek was also pretty smart, and seemed to be a genuinely nice guy. He was glad Emily could finally find someone up to her standards, but he couldn't help being just a little jealous.
And he wasn't just jealous of him dating Emily. Even in the little picture, Derek's physique was obvious. He towered over Emily--just like he had over Kevin that first time they met--and his muscles were apparent, with his massive arms straining the fabric of his hiking shirt. The sex he must be able to have with that body. He must just be able to toss her around like nothing.
And though he tried to stop himself from thinking about it, he couldn't help but slide into a fantasy he had more than a few times:
Emily was staring deep into his eyes, her eyes filled not only with love, but with desire for him as well.
"I've wanted you so bad, Kev," she said. "All these years, I've always wished you would just bend me over and fuck me like the horny slut I am."
Kevin felt himself start to get hard. As wrong as it felt to jerk off on his best friend's couch, he was already too horny to stop himself from rubbing his cock through his jeans.
He imagined Emily taking off her shirt, imagined what her breasts would look like. In his fantasy she was completely naked now, with one hand reaching between her legs.
Kevin got even harder. He was sweating now, despite it being a particularly cold night. His head was... so fuzzy. It was getting hard to think. Getting hard to remember where he was, what he was doing. Getting so hard. He knew he had to strip. Had to get naked. Had to jerk off.
Before he knew it, his clothes were off and he was slowly stroking his throbbing cock. It felt so wrong to do this in his best friend's apartment, but he was too horny to care.
And then the fantasy shifted. Emily wasn't looking at him anymore. She was looking at Derek.
Worshiping his body, running her hands all over his massive frame. Making him moan as she licked his nipples. Getting on her knees. Pulling down his shorts. Revealing his massive cock. It must be huge. So big, hard, and imposing. A perfect cock for a perfect body. Sucking his cock, doing her best to take the entire thing down her throat. Derek moaning in pleasure, playing with his own pecs, his own nipples. Using his other hand to force his dick further into Emily's mouth. Then, Derek bending her over. Slowly sliding his dick into her. Fucking her. Faster. Harder.
Kevin was stroking his own cock even faster now. He couldn't believe he was imagining his best friend fucking her boyfriend, while he masturbated on her couch. But he was too lost in his own fantasy: her bent over, nothing but sex on her mind while Derek pumped his big cock in and out of her. Both of them moaning in pleasure as Kevin watched and stroked. He wanted it so bad. Needed it.
And suddenly, Emily stared right at him.
Her eyes weren't the caring eyes of his best friend, or even the lustful stare of the Emily from his usual fantasies. They were red, and glowing, and irresistible.
"See? This is what you could have had. What you still can have. Don't you want it? The power? The confidence? OH FUCK YES!"
The warmth blazed in his head now, his eyes went wide as it started to take over his mind, making it hard to think straight. He could only focus on her eyes, and the pleasure he felt.
"I want... No, what's happening?" he stammered.
"Don't you want me to be yours?" she asked, her voice dripping with sex, trying to draw him further into the warm haze.
"I... want... you..."
"Don't you want to fuck me whenever you want?"
"Fuck you..."
"Don't you want to treat me the way I deserve? Like a slut."
"Slut..."
Kevin was stroking his cock as hard as he ever had before. His arousal continued to build. He felt like his body was on fire, like steam should be coming out of his nostrils with each ragged breath.
