mean dom jun, degradation, slight choking

the moment gyu starts feeling so fucked out that he starts spreading himself even more, a cold slap to the face strikes him back to reality. he’s in no position to complain about the pain so he just whines out needily and brings his legs back in.
“that’s right, baby. you’re only gonna take what i give you, yeah?”
“but hyung…” yeonjun halts all his movements. poor beomgyu cries out loud when he becomes abruptly empty.
“no complaints or we're done here.” beomgyu looks at yeonjun with those puppy eyes, making yeonjun slap his other cheek. “don't give me that look. i have a better idea.” yeonjun picks gyu up so he's hovering over his lap. “stay still, pup.”
beomgyu sinks down just a bit further to close on the distance and hopefully make it more comfortable for the both of them. yeonjun lies down a little more to plant his feet on the bed to thrust up into him better. he slips the tip in and teases gyu by shallowly thrusting in and pulling all the way out. beomgyu seethes through his teeth and holds onto the headboard for dear life.
“can’t say anything now, huh? beomgyu glares down at yeonjun’s smirk, rolling his eyes. another slap, hard enough for beomgyu to stay staring at that direction to control his bubbling anger. “answer me, pup.” yeonjun grabs beomgyu’s chin to make him keep his eyes locked onto his. no response.
another slap, but this time yeonjun holds his jaw in place, making the impact sting more than it should. a tear threatens to fall from beomgyu’s eyes. he keeps quiet to show yeonjun that he won’t back down.
“what, did i turn you into a pain slut now? you doing all this just because your cock aches a little more when you get hurt?” yeonjun glances down at gyu’s painfully throbbing dick, feeling satisfied that his point is backed up by real evidence. still not a single sound from beomgyu.
oh… yeonjun’s pissed. “oh you thought i was just fucking around about that earlier?” he grabs beomgyu’s neck, squeezing hard enough to make him get choked up. and enough for yeonjun to throw beomgyu off of him and back down onto the bed. he gathers all his clothes and storms off into his room, annoyed that beomgyu’s been keeping him from cumming the whole day.
“hyung, i-” it’s already too late. yeonjun’s slammed his door and slammed the dood of his own room.
(they end up having nasty hate sex after yeonjun got caught moaning like a bitch in his room. and beomgyu slaps him back :])
