ADV-SR0006 - Climax Digest: Perversion Encyclopedia

The cover art is too hot! The face-covering restraint mask is super perverted and hot, and having belts wrapped around her breasts and hanging them with bricks is just too erotic! Also, being restrained in a board that locks the head and arms, like something you'd see at a guillotine, is so hot! It's packed with other extreme highlights too! Seeing three people with their necks locked in a board at the same time was novel and shocking!
