My stepsister tricked me into letting her ride my cock

My naughtiest stepsister offered to give me a massage. Little did I know she had other plans. While she was massaging my body, she made me grab her tits. I tried to stop her, but she was unstoppable. She ended up taking out my cock and giving me a blowjob. I thought she was going to stop there, so imagine how I felt when she went on to ride my cock like a cowgirl.
