So. Male!Hungary and fem!Prussia have been friends forever. Of course, "friends" here entails that they shared their first kiss, their virginity, and whatever else you want, even though they never dated each other or saw themselves as romantic. The reasoning behind sharing all their first sexual encounters was because they trusted each other c:

After an unprecedented amount of time where both Gari and fem!Prussia are single, they decide that they really need to get laid... and what better way to fix that than by becoming sex buddies?

Roll with it, anons. ;)

Bonus: Angstttt. Like, idek, A falling in love with B but B rejecting them? Whatever.
Bonus2: male!Prussia.
