An adult sibling role-play confession. There is nowhere left to relax in this house. My adult sister told me she had a boyfriend but knew nothing about sex, so I jokingly offered to teach her. Now she secretly drains my semen even when our parents are home. Not even the bathroom is safe, and lately I can barely get a decent night’s sleep. Today she even brought restraints. At this rate, she is going to drain me completely dry. Someone, please save me.
