when i went to my girlfriend's house for the first time, her cute jk stepsister was introduced to me! when i peeked into her room with a bit of a dirty mind, she was moaning and masturbating alone! when she noticed me peeking, she blushed and told me why she was masturbating. she said she wasn't satisfied with sex with her boyfriend... she confided in me about her troubles. to encourage her, we ended up doing mutual masturbation, and on her first public masturbation, she came immediately and i fucked her tight pussy right away!
