this has happened in other stories, and I find it funny how poeple pick and choose when and what makes them uncomfortable. then they turn around and eat up the same scenario in the next story.. talking about "I love a beefy bottom" or whatever, when its obvious the character doesn't want to - they're either forcing themselves, or they're being forced or coerced by the top, etc.
and I'm not pointing at you specifically, just an observation from comments under various stories with a similar situation.

I reaaaalllly don't like the way he's pretty much forcing himself to bottom for the white haired guy, it doesn't feel right at all
