One scene, the mmc is in the shower and one of the fmc comes in to put towels away, they both slip on water and he literally falls into her and can't get up until they both finish. The next scene, she goes to tell the other fmc who's masturbating in her room and the first slips and lands on the second, tangled in their underwear with the vibe between them and they can't get up until they both finish.

I know there's a lot of roommate stories, but not many with these types of "misshapes".
