God, if only it wasn’t so wrong. If only it wasn’t so fun. Sunoo would have ditched a long time ago. But it is wrong and it is fun. Sunoo never really valued the concept of a loyal friendship, they’re just acquaintances to get you through life without being depressed anyway. 

So this is easy. Wonyoung is easy to fool, Sunghoon is easy to fuck. It’s perfect. They’re the perfect dysfunctional couple. And it isn’t until Sunoo is guiding Sunghoon through the process of fingering a boy that he realizes this. 

Watching Sunghoon’s facial expressions as he stares down at the fingers currently thrusting into his ass. Sunoo bites back a moan, his breathing becoming staggered as Sunghoon begins to experiment and curves his fingers upward inside of him. 

“Fuck, that’s good. That’s-“ Sunoo cuts himself off with a high pitched moan. “That’s so good.” He sighs. 

Sunghoon leans over Sunoo to kiss him full on the lips, muffling a bit of his moaning. As they’re kissing, Sunghoon adds a fourth and final finger- making Sunoo break the kiss and toss his head back with a slutty whine. 

Sunghoon doesn’t know how he got to this point. How he went from being bored at a party to preparing his girlfriends best friend to have sex. He doesn’t know anything about Sunoo, yet can’t seem to get enough. He doesn’t know what will happen afterwards, if Sunoo will leave or if he’ll stay. He knows this is wrong, that he’s effectively cheating on his girlfriend of 3 years. That he’s already cheated several times. 

But right now, right here, he doesn’t care. Hell he’s not even thinking of her, he’s thinking about how much he loves the way Sunoo’s expressions twist as he pumps his fingers in and out of his hole. He’s thinking about how his cock is going to feel inside of him, how good it’s going to feel when he cums for the second time tonight. 

“I’m ready, please- fuck.” Sunoo whimpers, his fingernails digging into the skin of Sunghoon’s shoulders. 

“What is it, baby? What do you want?” Sunghoon asks. 

“Fuck me, please. I just-“ Sunoo cuts himself off with a sob, barely able to control himself as he feels the slightly burning stretch in his ass. “Need you.” 

Sunghoon smiles triumphantly to himself and pulls out his fingers. He hears a quiet whine when he does, implying Sunoo wants to feel full. 

And who is he to deny this precious boy's wishes? 

So he gets into a comfortable position, and lines up his cock with Sunoo’s entrance. He feels Sunoo’s sharp fingernails raking up and down his back as he slowly starts easing himself in. And my god, he’s never felt anything like this. 

Sunoo is just sucking him in, welcoming him with a steady pulse. He feels the way the rim starts clenching around him, nearly squeezing the cum right out of him. 

“Oh, fuck.” Sunghoon moans quietly. “Does it always feel this fucking amazing?” 

Sunoo doesn’t hear the question, his brain is mush, eyes misty as he feels Sunghoon burying his cock to the hilt. All he can hear is the ringing in his ears. 

Once Sunghoon is balls deep he pauses, as instructed earlier by Sunoo. 

“Sex is never gonna feel the same again.” Sunghoon says out of breath. 

“Stick with me and it always will.” Sunoo whispered hotly into Sunghoon’s ear. “You can move.” 

Sunghoon slowly pulls out until nothing but the head is left inside, and half a second later he’s thrusting inside. He repeats this motion over and over and over until Sunoo is practically gurgling his words, shameless moans and whines and sobs pouring out of his mouth like profanity. 

The air around them gets warmer and damper as the intercourse continues. 

“Faster, faster, please.” Sunoo begs, wrapping his legs around Sunghoon’s waist and locking his ankles at the base of his spine. 

Sunghoon grants Sunoo’s wish and starts moving faster, hips snapping back and forth faster than before. Sunghoon is groaning and grunting above Sunoo, taking pleasure in the way Sunoo’s walls suction on his cock. It’s hot, it’s wet, it’s warm- and it is so fucking sexy. 

He feels Sunoo’s walls sucking him back in every time he thrusts in, and it feels so good. He listens to the squelching noises from his precum leaking into Sunoo and his brain goes haywire. 

Sunoo cries out a wonton moan, noises released directly into Sunghoon’s ears. 

Sunghoon latches his lips onto the soft skin of Sunoo’s neck and sinks his teeth. He alternates between licking and sucking, and he repeats this until Sunoo’s neck is littered in love bites. 

He leaves open mouth kisses across his collarbone, pulling on the fabric of his shirt to reveal more soft milky skin. 

Sunoo bites on his bottom lip to suppress some of his moans and tangled his fingers through Sunghoon’s back sweaty hair. At this point they’re both sweaty, but right now Sunoo couldn’t find it in him to care. Not when Sunghoon’s cock was ramming into him at a godly pace. 

He feels every vein and curve of Sunghoon’s cock engraving in his walls, like they were made for each other. He’s loving every bit of Sunghoon on top of and inside of him, Sunghoon is nearly laying on top of him- and they’re so close, Sunghoon’s face is buried in the crook of Sunoo’s neck with one hand has an iron grip on his thigh and the other is balled in a fist next to Sunoo’s head. 

Sunoo wraps his arms around Sunghoon’s shoulders, just to keep them closer. He tosses his head back when Sunghoon slightly changes angles, the hand on his thigh circling around his waist to slightly lift him off the bed. This new angle gives Sunghoon direct access to Sunoo’s prostate, and when he finally reaches the rough bundle of nerves Sunoo absolutely loses his mind. 

“Oh my god, fuck, fuck, that’s so good, fuck that’s- ahh” Sunoo cuts himself off with a whoreish moan, head thrashing about, somehow not able to process the pleasure. He starts rolling his hips in a rhythm with Sunghoon’s thrusts. 

Sunghoon uses his free hand to slip his hand under Sunoo’s shirt and pushes it up so it sits on his chest just above his nipples. Then something glimmers in his eye, something shiny. When he finds the source he almost cums right then and there. 

“Holy shit.” He pants, hips suddenly picking up the pace. 

“You like?” Sunoo asks in between moans with a cheeky smile. 

Sunoo has a belly ring. It has pink and white rhinestones and a tiny silver heart between the gems. It’s so hot. 

“I thought…thought you said piercings- shit - weren’t your th-thing.” Sunghoon tries to say, he’s barely able to. 

“Thought I’d try something new.” Sunoo replies. 

Sunghoon leans down to leave wet, open-mouthed kisses on Sunoo’s chest and tummy. He trails his kisses back up and seals his lips over one nipple, flicking his tongue over the hard pink bud. 

Sunoo’s back arches off the bed, practically feeding Sunghoon. The feeling of Sunghoon’s tongue on his nipple and his fingers rubbing circles on the other amplified the pleasure by a million. 

Sunoo notices that Sunghoon’s hips begin to falter and he’s breathing much harder than before. 

He’s tired, cute . Sunoo giggled to himself. He firmly placed the palm of his hand on Sunghoon’s chest and pushed until they flipped and Sunoo was now on top. 

“Relax, baby. It’s my turn.” Sunoo leans down and whispers into Sunghoon’s ear. 

Sunghoon’s jaw fell wide open, dwelling in the new sensation as Sunoo fucked himself on his cock. 

Now that he’s sitting on top Sunghoon’s cock stabs deeper into him, and he starts moving his hips. Sunghoon’s hands fly up to grope at Sunoo’s thin waist, knees bending to support Sunoo’s back. 

Sunoo starts bouncing, and his head falls back. He’s releasing moans and whines Sunghoon has never heard before, and it’s all going to his cock- just further pushing him to his limit. 

Sunghoon thrusts his hips up, earning a near scream from Sunoo. 

“Fuck, fuck, God I love your cock.” Sunoo whines, trying to bounce faster, albeit a little harder with shaky thighs. So he starts moving his hips in circles, his hands planted on Sunghoon’s abdomen to keep himself up straight. 

Sunghoon groans deeply, hips randomly snapping upwards, the sound of Sunoo moaning and crying out ringing in his ears and it’s all he can hear at this point. 

With one particular thrust Sunoo nearly falls forward, he catches himself and now his hands are on the mattress on either side of Sunghoon’s head. Sunghoon perches a hand on the small of Sunoo’s back and pulls him closer, the other hand wraps around to hug Sunoo’s waist. 

Sunghoon lifts his head to press loving, wet kisses to the smaller boys shoulder. 

The sounds coming out of Sunoo’s mouth are so erratic and mixed that Sunghoon can’t tell if he’s moaning or just straight up crying. 

Sunghoon reaches up to move the damp hair away from Sunoo’s face and tucks it behind his ear. Sunoo turns his head and locks their lips in a messy, salivating kiss. 

“I’m close.” Sunoo whimpers in between kisses. 

Sunghoon also feels a pit of warmth building up in his stomach. So he fucks into Sunoo faster and harder, the friction between their bodies effectively rubbing Sunoo’s cock- literally jerking him off. 

“Me too.” Sunghoon pants. 

“Cum inside me.” Sunoo whispers, pushing Sunghoon over the edge. 

This comment sets Sunghoon off and his hips start stuttering, and suddenly he’s releasing into Sunoo’s ass. The warm and sticky fluid fills Sunoo to the brim. 

Sunoo follows not long after, the feeling of Sunghoon’s cum filling him up flipping the final switch and he’s cumming, ropes of misty white squirting out of his cock. 

Sunghoon slows down his thrusts until he’s eventually milked dry. 

They lay in their position for a minute, both just catching their breaths. Eventually Sunghoon rolls them over and pulls out of Sunoo, the rim of his hole pulsating around nothing. 

Sunghoon doesn’t really know what to do now, so he just sits on his knees awkwardly and asks. 

“What now?” 

Sunoo just wears a lopsided grin. 

“Now, we shower. I am not going to sleep covered in my own cum.” Sunoo replies. 

Sunghoon nods. Then pauses. 

“Wait, you’re staying for the night?” He asks. 

“Well I can’t go home. I told Wonyoung I’d be out all night.” 

So not long after Sunghoon is helping Sunoo to his feet and walks them both slowly to the bathroom. Sunghoon didn’t know Sunoo would have so much trouble walking. 

He sits Sunoo on the toilet while he sets the water temperature. 

“I didn’t…hurt you, did I?” Sunghoon asks, genuinely concerned. 

Sunoo just shakes his head. 

“It’s normal, it happens all the time.” 

Sunghoon nods, secretly relieved. 

They get into the shower, and Sunoo is still practically hanging off of Sunghoon. 

They’re both aware of how close they are, they even shared a few kisses while Sunghoon helped Sunoo with the body wash. 

But then, as Sunghoon was lathering the shampoo into Sunoo’s hair, the energy between them was different. Sunghoon was so focused on Sunoo’s hair that he didn’t realize Sunoo had been staring at him until they locked eyes. 

And suddenly he couldn’t look away. He had never quite realized how…how pretty Sunoo was. He had a fox’s eyes, they were fierce but his cute plump cheeks evened out his features. 

Sunoo was starting to see what Wonyoung saw in her boyfriend. Sunghoon is caring, a man of detail. Maybe not the most loyal man in the world, but he sees it. 

It takes a lot for Sunghoon to break eye contact, but he manages to do so and begins rinsing Sunoo’s hair. 

Sunoo’s hands reach up to touch either side of Sunghoon’s face and pull him in for a kiss. And it’s different. It felt like the kiss they shared on Wonyoung’s bed. It’s slower, and deeper. No intentions to go further than kissing. 

They just stand under the warm water, kissing softly. They both completely forget where they are until the water begins to get colder. 

“I’d love to keep this going but we’re going to run out of hot water pretty soon and I need to clean myself off.” Sunghoon says quietly with their lips still really close. 

Sunoo breaks into a fit of giggles and steps around Sunghoon to let him do what he needs to do. 

They finish showering and Sunghoon lets Sunoo borrow some clothes while his are thrown into the washing machine. 

Sunoo’s sitting on the edge of the bed, waiting for Sunghoon so they could sleep. To his surprise, Sunghoon returns with soap, water, cotton, and sterile saline. Why the hell Sunghoon has sterile saline was beyond him. 

“What’s that for?” Sunoo asks. 

“You got the piercing recently right?” Sunghoon asks, getting on his knees in front of Sunoo. 

Sunoo nods, his eyebrows screwed together in confusion. 

“With a new piercing you should clean it daily for about four weeks, and getting cum on it can’t be good for it. So I’ll clean it, just to be safe.” 

Oh. 

Oh .
