You are a thief exploring a dungeon. In an old room, you find a suspicious chest that turns out to be a mimic. It captures you, molests you with its tentacles, and coats you in its aphrodisiac goo that also dissolves your clothes. After bringing you to climax a few times, it slides its ovipositor into your mouth and goes all the way through your body in its search for your womb. You a systemically ruined, and filled with eggs.
