Ava Sinclaire is at her friends house but she is nowhere to be seen. She was supposed to go shopping with her friend but she ended up at her boyfriend's house. Her friend's brother Nathan, who was working out in the garage, bumped into a heavy bag and asked Ava if she wanted to try it. She didn't know how to throw a good punch, so Nathan told her it was all about the hips and showed her how to do it. It turned Ava on so much that she would rather take his cock in her mouth and fuck her tight little pussy instead.
