I need help finding a hentai manga that I read years ago. It's about a boy who's father's truck breaks down at the side of the road, so he goes into a shack to get help. He goes down the stairs into the basement and he finds a small girl. Turns out, the girl's a trap. They fuck, and then the boy turns into a trap, and the trap turns into the boy. The trap goes back upstairs leaving the boy stuck in the basement forever. I've searched everywhere, but have come up short. Any help?
