A girl with a severe rubber fetish always desired full-body rubber play, but couldn't bring herself to confess her kink to her normal boyfriend. Unable to suppress her desires any longer, she devised a plan: to restrict her boyfriend in a specific way, dress him in the rubber suit she had prepared, bind him so he couldn't move, and enjoy rubber play while he was completely restrained. This plan, aimed at making her boyfriend obsessed with rubber, became a crucial step toward fulfilling her deepest wish.
