I was wondering if this should be rated M? At the time I didn't think it was necessary so I will just leave the warning again.

WARNING: Boys making out and getting hard 

On days they are allowed a early night in, the two youngest members of NCT 127 could be found on their shared bedroom having some quality boyfriend time. As usual, Donghyuck is straddling Mark’s lap, being thoroughly kissed like it was expected after two long weeks with energy only for a chaste goodnight kiss.

Like it’s natural when young boys make out, hard-ons are to be expected, and although it happens frequently, they never did anything about it. When things start to get too hot, one of them start slowing down until they end up cuddling on the bed, cooling down. It happens that one of them is too pent up to calm down, so he ends up in the bathroom and then comes back for some cuddles (yes, because cuddles are never too much).

But today is different. Since it has been a long time, when they started making out things got hot all too quickly, weeks of pent up frustration all came out now that they were together again. Rough hands palming above the thin clothes with no finesse at all, it shouldn't be that surprising when a hand slipped on sweaty skin making Donghyuck lose balance and instead of hovering, he ended up sitting on Mark's lap, bringing together their, until now neglected, hard-ons. From their joined mouths came a surprised moan and, instantly, Donghyuck tensed pulling away, an apology at the tip of his tongue. But before he could say anything or put more distance between them, Mark grabbed the other's hips securing him in place and kissed him, immediately deepening the kiss.

Confused, Donghyuck kept kissing the older boy but, the feeling of their lower halves touching didn’t let him relax. All the unexplored possibilities were making him slightly nervous.

Feeling his boyfriend still tense, Mark let one of his hand the other’s back, knowing it would calm him down. When he felt said boy loosen up, he let him control the kiss and, when his tongue was on his mouth he it, making the younger groan and his hips hitch and ground on his own. The friction created made both boys pull out of the kiss, panting, and stare into each other eyes. It was obvious that both wanted this, at least physically, but since they never went this far, both wanted to make sure that the other was ok with it.

Seeing the flustered sign of his boyfriend, Mark let a smirk grace his lips if only to see the tan skin of the younger blush even more. “.” ”Brat.”

With a uff, Donghyuck leaned forward and kissed Mark, biting his lip as retaliation for his smug attitude. With a squeeze on his hip as encouragement, he started slowly moving his hips, earning a deep moan from the other and making him now the cocky one. Lifting his hips high enough to stop touching the boy underneath him, he asked with a cheeky grin, “Something wrong, Hyung?”

Mark grabbed Donghyuck’s hips and pushed him down until there was only their sleeping shorts between them, startling a loud moan from the younger that he quickly muffled with his hand while bringing his mouth to his ear saying “Don’t tease Hyuckie.” and started on his neck, knowing that whatever mark he left had to disappear before their schedule tomorrow morning. When he was satisfied with the small pink hickey, he continued his way, leaving little wet kisses until he reached Donghyuck’s lips. But instead of kissing him, he let their foreheads touch, moving away every time the boy on his lap tried to kiss him.

“Now who’s teasing, hum?” Donghyuck pouted.

Chuckling, Mark kissed the other’s pouty mouth, who quickly twisted both hands in the older’s hair afraid he was going to move away, and deepened the kiss. After all the talking and teasing done, both boys wanted nothing more than solve the “problem” both had in their pants.

On the quiet dorm, on the youngest's bedroom, all you could hear were pants, groans and moans, the stray whimper that none would ever admit came from him, and the distinct sound of wet kissing and clothes rustling. Hips stuttering, kisses growing desperate and grips getting too tight, both boys reached their high moments apart and their lover’s whispered name on their lips.

Tired and still panting, both boys collapsed on their back on the ground, looking at the dark ceiling. “Ah~ I’m so sleepy.” Donghyuck said around a yawn, turning on his side and resting his head on Mark’s chest making him grunt. “I don’t really feel like getting up, can we go to sleep now?”

With a horrified look Mark asked, “And you want to wake up tomorrow with your boxers like that? Better, do you want to go to sleep feeling it getting dry and stuck to your-” “Alright! I’m definitely not tired enough to not go to the bathroom.” “Thought so.”

“.” Donghyuck breathed. “Did you said something Hyuckie?” said Mark already standing and offering a hand to help him. Grabbing the offered hand the younger said with a innocent smile, “Nothing.”

And together they stuck their heads out their room, looking in every direction to see if anyone was up and once coast was clear, they ran to the bathroom almost slipping on some forgotten tshirt.
