My adult sister role-play character is a messy shut-in with no job, poor eyesight from reading erotic comics, and the same unfashionable T-shirt she has worn since middle school. I never saw her sexually because she was my sister—until I caught her masturbating with total abandon. In that instant, my morals, ethics, and reason collapse, turning me into a lust-driven monster obsessed with her. Her neglected body awakens too, and I keep pounding deep into her pussy and creampie her again and again, too far gone to notice how many times she cums.
