I request a story with Sakura Matou from Fate/Stay Night.

She's been captured by an enemy master or servant and, for whatever reason (maybe a grudge, or just sadism), they decide to torture and rape her. I'd like lots of pain and sexual humiliation, but no scat or heavy mutilation (such as the removal of limbs, eyes etc.), and I'd prefer if it she managed to get free in the end.
