Karin Mizuno is helping a new guy get in shape

As Karin Mizuno was getting more and more experienced with golf, she started expanding her interests to other related activities, especially the way she was getting in shape with her teacher- sex. Today, there was a new guy who has signed up for classes, just like Karin did, a long time ago, so he had to go through similar stages of the whole training- first cardio, and then strength exercises, and then a bit of theory. Karin helped him take off his clothes and gave him a blowjob until his heart rate went higher and then he was supposed to fuck her from the back, for leg muscles workout. Teacher decided to join them a bit, just so he would stay in shape.
