i thought about this question long and hard and dare i say everyone makes him cry during sex because wiju is just a crybaby when he feels good. now lets say who has him sobbing so hard that he passes out as soon as things are over... which would have to be a few people instead of just one but for different reasons.

if euijoo gets fucked by fuma, euijoo is probably crying from, yes how good he's getting railed, but also just from the relief of getting to stop being a leader. i wouldn't say that fuma tries to be a dirty talker but the few things he does say hits euijoo so hard that it makes him choke up, especially with his prostate getting pounded so nicely. wiju cries while holding onto fuma too, hiding his face into his neck and hiccuping his moans and sobs. wiju would try to stay awake after being brought to tears but he feels so safe with fuma that his body and brain just gives in...

now if we're talking about who fucks euijoo so good that he's convulsing... im actually going to have to say its Maki. are we joking... maki is obsessed with his wiju hyung, he cant contain his carnal desire,, especially if euijoo is beneath him looking up with his wide eyes, plump lips, and slutty ass body. maki tries to be gentle at first but i like to think he gets carried away when euijoo is already near tears... he cant contain his excitement and then when hes really fucking.. he's gonna lose focus on his own pleasure to focus on euijoo's, sharpening his thrusts, grunting with force, scrunching his face to see what exact thrust has euijoo bursting into tears. once maki gets to that point, he's going haywire, he kinda blacks out, euijoo cant get him to slow down at all so he's drooling and his eyes are rolling back into his head. euijoo has his nails digging into maki's skin, he's sweating so much too, his hair sticking to his forehead and if maki were in control of his sex-crazed brain he would comb it away. i think euijoo would also cum quickly too, getting overstimulated because of course maki wont stop until he's reached his own high, so that adds to the tears. euijoo probably doesnt even remember how the sex ends either, because once he's came for the last time of that night he's waking up in the morning with his body aching. his cheeks are tearstained, maki didnt wipe it away during aftercare because he thinks his hyung looks beautiful with the tear streaks and his puffy post sobbing face in the morning... he'll probably even try to make wiju cry again as soon as he sees him awake.
