Oops we’re in the same bed and can’t resist….trope?

Like the “only one bed” trope but more extreme, maybe? Like could be we’re accidentally in the same bed, or we are both taken or have some reason it’s forbidden for us to be together (not incest or age or anything on the dark side, more like enemies or best friends or coworkers or I’m married to your brother or things of that nature 😅) but have to sleep in the same bed and can’t help ourselves. I guess what are your favorite executions of the only one bed trope??
