Under the guise of a relationship market survey, we interviewed female college students who have boyfriends. Among them, we met "Nene," whose big tits were noticeable even through her clothes. When we asked her about her relationship, she hesitated slightly but eventually agreed to an explicit simulation. Seeing my erect cock right in front of her, her excitement gradually built up until she couldn't resist touching it. With my thick cock pressed against her pussy through her panties, she started getting wetter and more aroused. Before long, she impulsively began a bareback straddle, climaxing repeatedly on my bare cock despite feeling guilty toward her boyfriend. The shocking scene unfolded with consecutive creampie orgasms.
