Your gym trainer is the only thing that gets yu hotter than the workout itself. She's noticed you admiring her before and decides it would be fun to dfo an unconventional cool off method. With ice she's placed in a bowl, she instructs you to stroke your cock to her crawling all over her weight bench and showing off her sexy body in her workoutclothes. Something about watching the ice melt on your hard cock excites you both as she has you going. Cube after cube melts and the drippier you get for hr incredible idea until it pushes you over the edge. What a nice way to end a sweaty time.
