Femdom training - vastpinnen is mijn cardio

Miss Wildfire's workout continues, and she is going to put her subs arse to use as she gets her cardio workout. With the sub knelt on the floor, Miss Wildfire slips in her large strap on. She starts slow and teasing, but then points out it wouldn't be much of a workout if she went slow, now, would it? She gets harder deeper and faster as she fucks the sub until he is flat on the floor, used and ruined!
