I'm looking for a prompt that (to my knowledge) was never filled. I remember that the tags on pinboard are wrong, and so it always took me forever to find it, and then I never bothered to contact one of the GKM mods to let them know about the error. And this time I can't find it at all, so shame on me. What I remember is under a cut, for trigger purposes.
Anyway, I remember bp!kurt is a virgin, and he gets raped in the locker room, and it says something about how he was saving it (his virginity), and now he's a gaping mess with come seeping out of him all over the place. I think the perps are the football team, but it might have been the hockey team or just some unnamed jocks. Thanks to everyone who helps me find it!
Note to mod: I used the genderbender theme tag to denote that it's boypussy fic, but I'm not sure if that's what you wanted because this isn't gender-altered kurt, rather it's (biological) sex-altered kurt, and to me the distinction between gender and sex is extremely important. But a lot of people group them together, so I tried to do what I thought you wanted. If I should have used the "other" theme tag instead, please let me know. Thanks!
