Hi.
I've been with this scene on my head for a few days now, and I can't remember the author or where the story goes or even where it comes from , but I remember a scene where, like on canon, Drew was feeling uncomfortable being undressed and someone, maybe Brian suggested that they got on their underwear too, but Brian wasn't wearing any, and he was ok with that, but someone brought him some boxers or something .
Thanks for the help.
Found! Thanks to
