Miss Nagai, feeling self-conscious about her curvy figure, decides it's time to hit the gym and start a diet. She begins her workout with some stretches, but her voluptuous body quickly catches the eyes of other gym-goers. Feeling a mix of arousal and embarrassment, she finds herself in a wide-legged pose, drawing even more attention as someone closely inspects her most intimate areas, leading to an intense and uncontrollable squirt.

As the session continues, things escalate during her workouts. Her trainer, unable to resist, grabs her head and thrusts into her mouth with force, culminating in a deep release down her throat. Later, while using an exercise machine, Nagai positions herself with her legs spread wide, welcoming a thick, raw cock deep inside her.

Despite her initial attempts to maintain composure, raw desire soon overwhelms her. She not only succumbs to the pleasure but actively craves it, begging for a creampie and ultimately getting flooded with a massive load of cum.
