Doble problema estilo hermanastra (Vanessa Cage, Elaina Raye) paja tabú

I got all caught up in the moment when my girlfriend's younger step-sister was telling me what a good guy I am. I couldn't help but reach out and touch her silky hair as she was paying me compliments and saying how she wishes she could find a guy as good as me. I can't help it if my hand dropped a little and found her tiny tit. It felt good from what I could tell. She didn't let me linger there at all but instead quickly excused herself to go study. I just let it drop and figured I would hang in the room until maybe she got curious about just what a good guy I really am and came back for more. I did not expect what came next! She apparently went to my girlfriend and complained that I got creepy. Next thing I know I am getting yelled at for hitting on her 18 year old step-sister. Hey, she is legal. I didn't think I was being a creep about anything. She called me a good guy! All I know is my girlfriend is surprisingly angry at me for something I didn't even do.
