Stepmom/stepson graduation present

Stepmom's stepson has graduated and she really wanted to get him a new laptop, but just couldn't afford it. She has an idea since she found a mature porn magazine in his room and thinks she should be his first sexual experience. She does a little strip tease then starts her deep throat blowjob before climbing on top cowgirl. She has her orgasm then lets him fuck her doggystyle but he forgets to pull out and cums inside her. Now she is faced with being pregnant as she shows later that she is.
