Sapnap and Karl were never alike. Sapnap was the typical skater boy, never paying attention in class, ripped jeans, band shirts, popular. Karl however was a teacher's pet, good grades, not many friends, always reading, a good example. Yet somehow they got along like there was no difference. No one ever questioned why they were so close, they just thought it was some sort of family friend type of thing. Little did they know the real truth.

They met when Karl transferred from a different state, and Sapnap was asked to show Karl around the school. They quickly developed a bond after that. A bond that quickly sparked into feelings for each other, and then lead to them dating. They never showed affection in public though, they decided to keep it on the low and away from other people's business. Along with the lack of affection, it was hard for Sapnap and Karl to find anywhere alone in the school since there were so many people crowding Sapnap at a time. Most of the popular girls Sapnap would hang about with wanted to get with him too, so they would constantly push Karl away from Sapnap, along with sly comments of 'Why be that close to an idiot like him when you can be with me?' Sapnap always pushed them away and left again with Karl.

The pair were now in Karl's dorm, talking about random things or just enjoying each other's company whilst doing their own thing. Recently, Sapnap had been thinking a lot about going to the next step of his and Karl's relationship, but he had never voiced this. Well, not until that day. Karl was laying with his head in Sapnap's lap whilst they watched something on Karl's TV. Sapnap sat the other up, kissing him softly. Karl smiled and wrapped his arms around Sapnap's shoulders. "What's up?" Karl asked, leaning his head down to be resting on Sapnap's shoulder.

"Have you ever thought about going further Karl?" Sapnap sighed, running his hand through the soft brown hair of the other.

"What do you mean?"

"You know, like-" Sapnap took a deep breath and decided to just say it, "Have sex?"

Karl's face went bright red making Sapnap panic thinking he did something wrong. Before he could say anything, Karl's lip were pushed against his, only this time less soft than the last time. Their tongues fought for dominance, Sapnap eventually gaining dominance over the other and pulling him to straddle him. "Are you sure your okay with this?" Sapnap whispered. Karl nodded in response, kissing Sapnap again. Sapnap pulled away to quickly pull his and Karl's shirts off, the brunette's hands immediately moving to Sapnap's belt, both of them panting. His belt was undone and taken off, quickly being discarded off into an unknown corner of the room. Karl's trousers were next followed closely by his own, Karl now lying on the bed in just boxers, Sapnap hovering over his in the same amount of clothing.

Karl was clearly nervous. His legs were pressed together, hands on Sapnap's arms. Sapnap could tell this so he leaned down and started kissing Karl's neck. "It's okay, I'll be gentle. Are you sure you definitely want to do this?" Karl nodded slowly, relaxing and letting his legs fall apart slightly. Sapnap smiled and looked around the room, "Do you have any lube?"

Karl pointed to the drawers next to the bed, "The top one." Sapnap opened the draw and there it was. He grabbed the small bottle and coated three of his fingers in the liquid. He pulled Karl's boxers down with his other hand and pressed one of his fingers against his ass. He looked up at Karl, "Safe word is red, if you want me to stop either safe word or pinch my arm. If you want me to slow down,  yellow and if you're okay and want to keep going, green okay?" Karl nodded, "Do I have your consent?" Karl nodded before saying a quick yes, leaning his head back and resting against his headboard. Sapnap pushed one of his fingers in, causing the other to start squirming. "Are you okay?" Sapnap asked, getting a nod from Karl in response. He started moving his finger slowly, adding another after a while, getting a gasp from Karl in response. He stopped looking up at Karl. The younger was bright red and panting a the other started to move his fingers. He let out small gasps and whimpers every time Sapnap would push them further. He started to scissor them, spreading Karl further. The other was squirming a lot more now, wrapping his arms around Sapnap and pulling him closer to him. "It's okay, you're doing so well, it'll feel so much better soon." Sapnap kept whispering reassuring words into Karl's ear as he added another finger, not stopping this time, continuing at the same pace. Karl started to moan, a noise that Sapnap couldn't resist. He pulled his fingers out when he thought Karl was stretched enough, pulling down his boxers and using some extra lube, smothered his dick in the liquid.

"You ready?" Sapnap whispered whilst kissing Karl's neck, comforting the other whilst lining himself up.

Karl softly nodded and pulled his arms closer around Sapnap. The raven haired slowly started to push his dick into Karl's ass, making the other choke out a moan. The brunette tensed, clawing at Sapnap's back. He stopped thrusting and let Karl adjust. He waited for a few moments before looking to Karl. "What colour?"

The other hesitated for a moment before finally saying his answer, "Green." Sapnap nodded and slowly started to push more of himself in. Only stopping if Karl asked him to, continuing when he was ready. Eventually, Sapnap was fully in Karl, kissing his neck softly to decrease the amount of pain his lover felt. Karl moved his hips slightly, moaning when he did. "Okay, you can move now." Karl whimpered. Sapnap raised himself to be hovering over Karl and started to move. He wasn't going too fast or slow, but he was going fast enough for the brunette to start moaning loudly.

Sapnap increased speed every minute or two, making the brunette moan louder. Sapnap kept going faster and harder. Karl was screaming in pleasure now, leaving painful red marks over Sapnap's back. Nothing could be heard over Karl's moans and screams. "I-I'm cumming Sapnap!" Karl moaned, his back arching, his eyes rolling back and his tongue lolling out. "Me too Karl, just hold on a little longer okay." Sapnap looked down at Karl, admiring the way he looked, tear stained cheeks, deep blush and sweat rolling off him. Then with a loud moan Karl came, getting his cum all over his stomach and Sapnap's chest. After a few more sloppy thrusts, Sapnap came inside of Karl, groaning as he did. He pulled out of the younger and kissed him gently, standing after and dressing himself. He went into the bathroom and started to run a bath for him and Karl. He added bubbles and let the bath fill.

The bath filled fairly quick, so Sapnap turned off the water and went to get Karl. He picked up the brunette bridal style and placed him in the bath, undressing himself again and slipping into the bath, pulling Karl to lay on top of him. They stayed like that for a while, Sapnap cleaning Karl and himself before lifting himself up and out of the tub, wrapping a towel around his waist before helping the other to stand. Once in the bedroom, Sapnap slipped one of his shirts and a pair of boxers onto Karl, before getting his own boxers on. When Sapnap laid down, Karl was already asleep. The people in the dorms next to them had definitely heard them, but he didn't care, he would deal with that later. For now he stayed with Karl, together in their bed with no one to interfere.
