Performed by adults in a family role-play. After missing the last train, my drunk adult stepsister arrives at my tiny apartment with her female friend, and the three of us sleep side by side. Her friend’s clothes fall open, giving me a clear view of her breasts and panties until I can no longer resist touching her. Instead of getting angry when she notices my erection, she welcomes it and starts having sex with me beside my stepsister. The commotion wakes my stepsister, who gets horny, masturbates, and finally joins us for an all-night threesome.
