Megan Vaughn & Jack Lawrence in Naughty Athletics

Jack is training Megan in preparation for her bicycle ride from San Francisco to Los Angeles.

Titties a-bouncin', Megan's rising heart rate revs her engine enough to where she steps off the treadmill and takes control of the situation and shows her trainer what a real workout is.
