POV: We're step-brother & step-sister and you've come to visit me in my new house in preparation for my house warming the next evening. We're getting ready for bed and I slip into a babydoll dress, which reminds me of a nightgown I'd bought when I was younger. A gown I'm very surprised our mum let me buy! I reminisce over a time you and I were playing Monopoly and I was wearing said piece of clothing and you were getting distracted... Your gaze made me feel sexy. I coax out of you that you have masturbated over me (I have, too, over you) and we decide to watch each other do it this time... Please note: The name 'Tony' is used.
