Sister's Ulterior Motive

Your little sister comes to stay for a few days whilst she's in town for a "work meeting".. you don't mind, you'll be glad for the company, but.. surely she isn't purposely teasing you in those skimpy clothes? Why would your own little sister who is married, want to seduce her own big brother? "Accidentally" sending you rude selfies? Leaving her cute panties in the bathroom for you to jerk off to? It doesn't make sense.. until she comes clean after a couple of days and admits what she's REALLY bunking at yours for. Apparently she remembers you stealing her worn panties when you was younger and its led to her being OBSESSED with the i word! Her and her husband like to get kinky in the bedroom, spicing up their sex life by roleplaying as brother and sister.. but that wasn't enough, so she encouraged her hubby to actually fuck his biological sister FOR REAL and then.. well.. now she's wanting her own taste of taboo sex.. with her very own big brother to satisfy her urges..
