One day, I was drunk and sneaked into her bed to have sex with her. I felt something was off but continued, but it turned out to be her sister Sora! I mistook her for her and tried to stop her, but it was too late... "It's too late now, isn't it?" I said and inserted myself in the cowgirl position! With her seductive mouth and her skillful hip movements... Sora's beauty and figure are the polar opposite of my girlfriend, and I got a full erection without any hesitation! Cowgirl position, body-washing slut handjob, creampie sex... a total of 4 shots. 140 minutes at the mercy of my girlfriend's overly erotic sister.
