I met up with my girlfriend after her workout. Her flushed, sweaty skin that hasn't cooled down yet, and her hair that faintly smells of shampoo every time it sways in the wind, stir a man's desires and make the brakes fail. I pound her exhausted pussy with my overly energetic muscular dick, and she cums so hard she almost loses consciousness—it's adorable. Since this (sex) burns more calories, she's enjoying it too.
