Also, check the tag https://www.mangago.zone/tag/Sexual%20tension/
Neighbors stories are often has this trope of hearing the other fuck or something so I also rec checking out that tag

Ohh yeah didnt think of that thanks!!
Can someone recommend me manga with this very specific plot of something sexual happening between the MCs (not sex) so then they end up thinking about eachother, I know it's vague as hell but lol it's literally my favourite plotline for example I'm thinking something like my favs (Jackass!, Fukutsu no Zono, Pink Heart Jam, Minami-kun wants to be teased by that voice, and recently I read The stranger in the hoarding house which was great too)
