Hmm just the other day I was thinking what about a mnsng au where both of them are virgins lol. But Jsng assumed since his hyung is so put together & knows everything. He must have had his first time already. He even assumed him a bit of playboy because of all the girls and guys that flock around him & different dates he goes every other week. But Jsng is so so wrong. Mnho is a simple devoted man towards his Jsng. Though he did try to go out on dates with multiple people to try get over his feelings for Jsng. It ofc didn't work & he decided to confess his feelings under a lot of pressure from their common friends. Ofc Jsng said yes & mnho feel stupid for being so silly to not see the depth of their connection. Skip skip to their first make out session where things get heated & Jsng decided to confess that he's never done this before. And mnho tried to assure him & confess that he's the same. But got interrupted by Jsng saying that he trust mnho on this since he's already experienced & responsible lol. Now poor mnho is so much in pressure to make their first time perfect & does in depth research. Only to end up being awkward & fumbling around once he is in b/w naked Jsng legs for the first time. He is shaking more than Jsng when he's starts to rim his hole & finally ends up confessing about his zero sex game. And ofc Jsng finds it funny. Endearingly funny about his cool hyung. He giggles & they have very clumsy sex after apologizing for assuming. Months later after learning from experience & their friends tips(mostly fel!x) they are experts in bed. But Jsng still sometimes ends up laughing remembering their first time when his hyung pretend to be the bad guy during their smexy time. The end
