My stepsister thinks I'm gay. I told her I'm not, and that I'm just shy around girls, but she doesn't believe me. Last week, she called me into her room and point-blank asked me if I was into guys. When I told her no, she made me prove it to her by jerking off in front of her while she showed me her body! I have to say, I was definitely turned on... but when she told me that she was going to have her boyfriend come over so she could teach me to suck cock, I totally blew my load. Now I'm not gay, but I have to admit I'm a little curious. I couldn't believe it when she called me back into her room while our parents were away and told me she had a surprise for me. Much to my embarrassment she actually did have her boyfriend come over! She said that her boyfriend is her little bitch, and does whatever she tells him to do. She told me that she was going to jerk him off and wanted me to watch! When she took his cock out of his pants and started stroking him, my cock sprung to attention at the same time. She jerked his pole and told me that she wanted me to clean up all of his cum when she made him pop. She even offered to let me suck it a little. I'm not gay... but I did give it a shot - I mean, hey... it's not like we made eye contact or anything. Finally, as she got close to making him cum, she told me to cum at the exact same time and she would reward me. I timed myself and paid close attention to her boyfriend's cock - and lucky for me I busted a nut at the exact moment that he did! My sister made me clean it all up too, and I had to lick every drop. It's a good thing I'm not gay though, because it would have been totally gross if I was. Now I'm my big sister's bitch too I guess. Starring Cassandra Nix
