When he opens the door, his girlfriend, a traveling personal trainer, stands there. (It starts like a novel!) She has a calm smile and a sexy, toned body. Her white high-leg leotard is amazing! Any man would be sure to think, “I want to do it!” She glances around the room and immediately seems to have figured out his daily routine. “Your body’s a little stiff,” she says, and begins lightly stretching. Starting with instructions on warm-up exercises, to regulating his breathing and adjusting his posture, every movement is beautiful and efficient. The leotard digs into his crotch, and his nipples are clearly visible. If he doesn’t bend forward, she’ll know he’s erect. But she presses her body against his, supporting his stretches, and pre-cum begins to flow from the tip of his erect penis!!! Soon, sweat begins to trickle down his forehead, and his heart rate increases. As his heart rate increases, his rationality is destroyed… As the training progresses, it becomes clear that this is no ordinary exercise… this is something!! You’ll feel the security of being guided by a professional and feel as if you’re experiencing heaven on earth. Watch the naughty lesson from the famous personal trainer “Rin-san” who will pump up your sexy, cool golden flesh!
