Miss Nagai, self-conscious about her plump figure, decides to hit the gym to start a diet. She begins with stretches, but her curvy body draws close stares from other members. Aroused and soaked between her legs, she strikes a wide-legged pose, her deepest parts meticulously inspected, making her squirt. Later, during workouts, things get even wilder. The trainer grabs her head and fucks her mouth hard, unloading deep in her throat. On the exercise machine, Nagai, legs splayed like a frog, takes a thick, raw cock deep inside her. Though she tries to keep her composure at first, her reason crumbles under raw desire. Unable to resist, she not only welcomes the creampie but begs for it, getting flooded with a huge load of cum.
