Personal trainer Cherie Deville takes her job seriously, so when Ricky Spanish – the pervy son of her client – starts to cause a ruckus as he’s waiting for his mom's workout to finish, Cherie decides to give him a dose of dirty discipline. Unfortunately for Ricky, his mom gives Cherie free reign to put him through her paces as she sees fit. Initially, it seems like Ricky is merely there to get ground down by an intense and humiliating exercise routine, but after Cherie gets him alone and catches a glimpse of his hard cock, she decides to flip the script and guide Ricky through a much raunchier – but equally intense – workout.
