So me and my best friend decided to throw a little Halloween party in the backyard of my parents house
this weekend while they were out of town in Austin. Well I guess my Little step-sister caught wind of it
and told me that she would tell our parents what I was doing unless I let her and her best friend come to
the costume party. I agreed but begrudgingly. Everything was going good and quite a few people showed
up. It was a sick rager, even my step-sis and her friend Mindy seemed to be having fun. Later on in the night her best friend, cornered me by the keg and started mugging down with me outside. Then she took my hand and slid it up her Wonder woman costume and told me to feel how wet her pussy was. It was on like donkey kong and I was just about to take her to my room for a little boom boom. Well I guess Gabbie saw the whole thing and freaked the fuck out. She called her besty a slut and me an asshole then she ran inside the house where nobody was. Mindy told me to leave her alone and fuck her on the side of the house but I didn’t want Gabbie to do something crazy like call our parents. So I went in the house and there she was sitting on the couch completely upset. I asked her why she was so upset and after minute or so she confessed that she had a huge crush on me and her best friend knew it. Gabbie then proceeded to tell me that she masturbated to thought of me fucking her all the time. I though t it was hot and I told her not to be ashamed. I admitted to her that I saw her in the shower a few weeks back then I went and
jerked off to the thought of her. Gabbie liked what she heard and she made a pass at me. I tried to stop
her and tell her that it was wrong. But she was persistent. I couldn’t resist her charm and I ended up have hot nasty sex with my Stepsister. She came on my cock several times then I shot my load all over her beautiful tits. It was the best Halloween ever.
