Custom video. You are working out with me, your step-daughter who is home from college as a Kinetics major. I am helping you get back into shape by showing you some exercises. I take off the sweats at one point when I get too hot, and then notice your boner. Although initially weirded out, I decide to assist you in a different kind of workout. I tease you with my body before getting a shaker bottle for you to ejaculate into in order to save the cum. I tell you that I'll make a shake for you using the protein-rich cum that I didn't want to waste.
