I did it for me.

Stan stands on the side of the road outside of his house, shock freezing him in place. He is confused about what just happened. He practically begged his best friend to kiss him. His best friend who’s in love with him. Not just that, he promised to let Kyle go. For a kiss. ‘I’m so pathetic.’ Stan thinks to himself as he walks through his front door.
His mother and father are yelling at each other in the kitchen. Not unusual behaviour from their part. He ignores it and drags himself to his room. He sits on the floor against his bed and takes a deep breath in.
“What the fuck is wrong with me?” He says to himself, reaching under his bed for his secret stash of emergency weed. He rolls himself a generous joint and lights it. He puffs and inhales the smoke, letting himself get lost in the taste. He thinks back to what had happened moments before. He remembers the sensation of kissing his best friend, he's never felt anything like it and it scares him. He promised to let Kyle go but after that kiss, he's not sure if he can. He grabs his hair in a state of frustration and confusion. He liked Wendy not even an hour ago and yet he finds himself thinking about his now ex-best friend.
“Fuck it.” He mumbles before grabbing his phone, taking the napkin out of his pocket and typing in her number.
‘Hey, It's Stan. You free tomorrow night?’ He sends the message.
He throws his phone lightly across the room, making sure not to damage it before taking in another puff on his joint. He’s back to thinking about Kyle. He’s never seen Kyle in this light before. It’s frightening. He looks back on their time together. They’ve changed in front of each other. Kyle has seen his penis. They used to sleep in the same bed together. They used to cuddle in that same bed. How had he not noticed Kyle's feelings before? Best friends didn't do this type of stuff, couples did. He walks to his wardrobe and opens his photo album. It's full of pictures of him and kyle. He reminisces over their tie together, everything becoming more clear as he looks on. He drops the memories on the closet floor, wanting to rid himself of every single one.
Stan puts out his joint and lays in bed, not bothering to get under the covers. He dreamt that night. Dreamt of Kyle. Dreamt of kissing him, touching him, pleasing him. But, of course, it was just a dream.
Kyle walks home in a hurry, upset over what just happened.
‘What is Theo going to say?’ is all Kyle could think as he is greeted by the sight of his house in the near distance. Theo was probably asleep in Kyle's bed right now. A bed that Stan would sleep in on most weekends, the others they spent at Stan’s. He is filled with anxiety as he quietly opens his front door and tip-toes up the stairs and into his room.
He takes his trousers and t-shirt off and slips into bed next to the smaller brunette.
“Sh, it's just me. Go back to sleep.” Kyle murmurs after noticing the bug eyed boy stirring.
“Goodnight, kyle.” Theo says as he turns to face the gingette.
“Goodnight, T.” Kyle smiles as kisses Theo’s nose and closes his eyes. Kyle feels dirty. Like he has already tarnished a relationship that hasn't even started yet. He needs to forget Stan and focus on the beautiful boy led beside him. And he does. He worms one arm underneath the brunette, the other holding his waist, lightly spooning him. Kyle smiles, he feels content. Almost.

Stan wakes up to a text from Wendy.
“Hey, Stan! I’m pretty busy up till 18:00. What were you thinking of doing together? :)”
Stan reads the message, his stomach twisting with excitement. He forgets about his passionate kiss with a familiar redhead and completely focuses on Wendy.
“How does dinner sound? I can get a reservation at Bennigans if you’d like :)”
She responds almost instantly.
“Sure, try and get a time around 19:00, table for two ;)”
Stan hasn't looked forward to a date in a while. Of course he dated in college, but nobody quite made him feel the way Wendy did. Nobody other than Kyle, not that he would ever admit it. He calls and books a reservation for 19:15. The reason being he knows what girls are like when they get all dressed up. He sends one final message to Wendy informing her of the time and leaves for a shower.
He reads the time. 10:38. Only 8 hours and 37 minutes until his date with Wendy. He’s actually excited, he missed when he and Wendy would go out alone. He didn't have to listen to her friends and she didn't have to get insulted by his. It will be just the two of them. Now he starts feeling nervous. He can't remember the last time he and Wendy had a date without someone there. He shakes off his nerves and decides to go for a shower. He takes his phone out and begins to put on some music for himself to jam to whilst in the shower. His mind ponders back to the date he’s going on today. He changes the temperature of the water to cold.
By the time he gets out the clock reads 11:24.
‘That's the longest shower I've had in a while.’ He thinks to himself as he leaves to find some casual clothes to wear. He goes through his wardrobe when he finds a bunch of pictures scattered across his closet floor. He remembers dropping the album last night and comes to the conclusion that some of the pictures must've fallen out.
Still in his towel, he bends down and picks up each picture one by one, stopping when he gets to one in particular. It’s another picture of Kyle. He’s posing by Stark's Pond, his hair wet from swimming in it moments before. Stan's eyes travel down, Kyle’s naked torso also wet. He finds his eyes going further south. He stares at the bulge in Kyle’s swimsuit, feeling his own hardening.
He takes the picture and closes the closet door. Stan walks over to his bed, takes his towel off and throws it on the floor. He has the picture in one hand and his now completely hard dick in the other. He stares at the picture whilst rubbing his thumb lightly on the tip of his penis, he shudders. He then grips his erection and slowly pumps, moaning lightly with every movement.
He closes his eyes and thinks about Kyle. He thinks of the kiss they shared the night before. He thinks of how Kyle held his face as they passionately made out. He thinks of the way Kyle's mouth felt on his and how his mouth would feel wrapped around his uncut cock.
Stan groans as he pumps his dick faster, precum leaking out of his tip. He thinks about how he’d feel inside of Kyle and how Kyle would feel inside of him. The thought alone was enough to send Stan over the edge with a loud moan as he arches his back slightly.
He is led on his bed breathing heavily as he realises what he had just done. He just wanked to his best friend. And he knows he’ll definitely do it again.
