A hopelessly fashion-challenged delinquent sister was asked out on a date by a serious guy and came to me for advice! 'You should wear something cute!' I advised, but she came back with a tight-fitting knit dress! The different atmosphere and her overly erotic figure made me hard, and I lost control and inserted my dick! I thrust vigorously and came inside her. I thought she would blow up... but instead, she begged for it to be released inside her continuously, experiencing multiple intense orgasms!! My delinquent sister turned out to be a tsundere slut!
