Stepsister entices me to give oral to her boyfriend as he observes

My stepsis lured me to service her boyfriend. She's a pro, and he's an eager observer. It's a steamy amateur exchange with a cum-filled climax.

My stepsis is a total vixen, always up for kinky fun. When her boyfriend came over, she had a wicked idea. She wanted me to service him, a young stud who loves his pussy. I'm not into dudes, but anything for my stepsis. I got down on my knees, unzipping his pants, revealing his hard cock. I took it in my mouth, sucking and stroking, making sure to please my stepsis's man. Her moans echoed in the room as she watched me work. I didn't mind, I was just doing it for her. After a while, her boyfriend was close to coming. He pulled my head off, spraying his load all over my face. I swallowed every drop, not wanting to waste a single drop. My stepsis was thrilled, her eyes lit up with pleasure. It was a wild ride, but totally worth it.
