It was my birthday and things were about to get crazy. My cheerleader stepsister Kait had been teasing me for months. She was always walking around the house in tiny outfits, showing off her tight body. I wanted her so bad, but I thought she was just promiscuous and I didn’t want to be just another guy on her list. That night, my stepsis Kait threw me a surprise birthday party. After everyone left, only me, Kait, and her hot friend Haley Reed remained. Kait looked at me with a naughty smile and said, “I’ve got a special present for you, big brother.” She pushed me onto the couch and started kissing me passionately. Soon Haley joined in. The two girls made out in front of me, their tongues dancing. Kait pulled her top down, revealing her perky tits while Haley licked them. Kait got on her back and spread her legs. I buried my face in her shaved pussy, eating her out while she moaned loudly. Haley sat on Kait’s face, getting her pussy licked. Then I stood up and slid my hard cock into Kait’s tight pussy in missionary. She wrapped her legs around me as I fucked her deep. We switched positions constantly. I took Kait in doggy style while she ate Haley’s pussy. Then Kait rode me in reverse cowgirl, her perfect ass bouncing on my cock. Finally, she switched to cowgirl, riding me hard while Haley kissed her. At the end, both girls got on their knees in front of me. They took turns deepthroating my cock, looking up at me with hungry eyes. I couldn’t hold back anymore. I exploded, shooting thick ropes of cum all over their tongues and pretty faces. The girls kissed each other, swapping my cum. Best birthday ever.
