This one maybe?
unfortunately it's not but ty :')
not sure if it was a oneshot or not but i remember the seme and uke being sex buddies(? maybe boyfriends? idk) and having sex outside constantly.
i don't remember who was the one who was bothered by this but the reason why they only fucked outside was because one of them didn't want to wake up to an empty bed after spending the night with each other. after talking it out, they finally fucked at one of their places (i think) and woke up next to each other the next morning
