Oh wow okay you tapped right into the glove kink a fic gave me a while back
Here's some sleep deprived thoughts its 1 am
So I'm thinking it's mnho handling over all control to Jsng-making jsng wear gloves while mnho gives him the best head of all time, make it so difficult for jisung to not grab mnho and fuck him senseless
Jsng just leaning back on the couch or bed flexing his latex gloved fingers and getting used to having them on. It's a new feeling with it being banned in their little household due to Mnho's allergy.
Mnho kneeling between jsng's legs, innocent face and all, reminding him again that one slip up and Mnho could end up hospitalised.
Jsng is confident at first, that nothing would go wrong. That he has complete control. That he will be careful with Mnho. But that confidence starts fo waver when Mnho's warm and wet mouth finds his dick. Jsng can tell that Mnho is putting extra effort into it, taking him deep from the get go, letting out little moans, running his tongue on the vein on the underside of Jsng's dick.
It starts getting tougher for him to not grab Mnho by his hair, to not grab Mnho's head and push it down and hold him there so he chokes and stops letting out those moans that are driving him insane, to not brush away the tears that are forming on the corner of Mnho's eyes. He really wants to do all that. No, needs to do that. But the damn gloves. He promised to not take them off until after he cums.
But he also can't deny that a part of him is in love with the idea of the shared control. So he just leans back, his nails digging into those gloves harshly, says encouraging words to mnho instead, if he can't physically hold onto him, he will do so with his words
And all this while, Mnho has never been more turned on, it's incredibly hot seeing jsng's jaw clench on a particular bob of his head, noticing his fingers twitching, the look in his eyes. He loves the idea of handing over control while still having control, loves walking tbe fine line between safety and danger.
..fast forward jsng cums so much that it spills out and then mnho cums in his pants because he is a loser like that and jsng burns the gloves and cuddles mnho to sleep after washing his hands too many times. He says that he will never agree to this again but he knows its a lie
