In the thick of an intense training session, M-kun's personal trainer Ayumi can't resist the temptation to offer a unique mid-workout release. She drops to her knees, engulfing his throbbing cock in her full, sweat-slicked breasts, milking him with expert precision. Her nipples harden, leaking a trickle of warm, sweet milk onto his shaft as she works him into a frenzy. Ayumi's eyes gleam with lust, her voice husky as she urges him to cum, and cum he does, erupting in a torrent of pent-up passion.
