I work as a personal trainer. In addition to regular gym workouts, I offer a special private service that's become increasingly popular among clients, helping me gain repeat customers. Today's client is Ms. Sato, a voluptuous woman looking to lose weight. I have her change into tight training gear—her skin-tight bra and panties accentuate her curves, making it hard to look away. Her busty, shapely figure becomes even more alluring during exercise. We start with stretching, confirming her flexibility as she easily touches her toes. Next, we move to push-ups, where I guide her to focus on her chest muscles while casually groping her bare breasts. She seems uncomfortable but endures it. During squats, her sheer panties highlight her round hips, making my cock bulge noticeably. While doing abdominal exercises on the machine, I assist her closely, bringing my cock near her face for added stimulation. Drenched in sweat, Ms. Sato remains flustered but compliant. I gradually escalate things—holding her inner thighs, touching her pussy—steering the session into increasingly erotic territory. During abs training, I make her grip my bare cock, pretending to correct her form while deepening the contact. I tease her nipples and grope her big tits, pushing her limits as she struggles to resist. Then, for inner thigh massage, I drape her legs over my shoulders, spread her thighs, and rub her wet pussy firmly. She moans involuntarily, but I convince her it's okay since we're in a private room, allowing me to intensify the stimulation. Using a balance ball for massage, I pull down her tight pants and knead her large ass, her sweating body now responding more intensely. I lift her legs and start standing doggy-style sex, gripping her pussy tightly and pounding her relentlessly until she climaxes repeatedly. Then, sitting on a chair, I take her from behind, thrusting hard while her big tits bounce with each movement. Next, I make her crawl onto the mat and enter her from behind, thrusting vigorously. Her big ass slams against me, milking my cock as she loses control and bucks back fiercely. Finally, I flip her onto her back and fuck her in missionary position, making her orgasm over and over before cumming deep inside her convulsing pussy with a creampie. The training session ends here, and she books her next appointment. Another satisfied repeat customer secured.
