Personal SEX at a Private Gym

"Is this really... a massage...?" Shoko is tired of her unsatisfying life, so she books a session at a private, members-only gym in order to change herself. And the one who opens the door and greets her with a wide business smile is Ryuto, her new personal trainer. After a short goal-building session, they begin with a massage... except... this doesn't seem like a normal pressure point massage to Shoko... why's he touching her breasts so much... and putting his fingers inside her...? She starts to feel a strange sensation... and suddenly she hears, "That's enough of a warmup. Now it's time for the real workout!" Ryuto takes out his massive, towering shaft and pounds her deep inside...! Shoko's in for the adrenaline-pumping, sexual detox of a lifetime working with a rock-hard muscle she never expected!
