MIDA-600: My colleague at work has a girlfriend... but he really loves my masturbation. When I'm aroused, he secretly lets me penetrate him and ejaculate inside him, so his work efficiency is super high!!

Upon joining the company, Momoka, aided by her superior Atsushi, vowed, "It's my duty to serve this person," accepting Atsushi's unreasonable orders and his penis with a smile. "Senpai, here's a masturbation device that can ejaculate anytime," she said, opening her pink, throbbing vagina. She became a completely convenient woman, using her vagina for intense penetration during work hours and even after overtime, whenever she was aroused! "Of course, since it's a masturbation device, it's cumshot inside..." Even the mouth above her obediently swallowed. Despite having a girlfriend she was about to marry... "Girlfriend? It's okay... because it's a masturbation device, it's not cheating..." Attracted by her natural personality and her sensitive vagina that immediately became wet despite being a masturbation device, she climaxed...!
