I hired a freelance personal trainer to tighten up my slack physique. The one who came was the cool 'Erika' sensei with her super plump and shapely ass! She noticed me staring at her overly sexy body and told me to focus, but then tempted me with a promise of a reward if I did well, showing off her beautiful ass... Touching her waist, riding her, and getting close to me, my rationality completely collapsed! A full course of 6 shots, including workout nymphomaniac sex, oil-slicked ass pounding, exhibition vibrator masturbation, and nymphomaniac cowgirl position... I was completely dominated by Erika Ozaki, the beautiful and voluptuous personal trainer, for 130 minutes of perverted workout enhancement.
