Kiss of Sin: Rewinding Flame

A swordswoman who hates weakness gets her hands on a ring that rewinds time, which sounds useful until you learn what it eats. Every reversal costs sexual energy, and every shortcut she takes now makes the next one pricier.

The setup is a debt spiral dressed as a second chance: she keeps buying her way out of mistakes with a currency that compounds against her. That's the whole hook, and the source doesn't dress it up further.

Play moves through a sandbox structure, letting her cross paths with women and monster girls alike while the rewind mechanic sits underneath every decision, quietly raising the price of pulling it again. There's no pretending the choices are free; the game just waits to show you the bill.
