Her colleague "moonaka" was someone she knew well from work. She seemed like a normal girl but had a secret side; she loved teasing men and being a sadistic dominatrix! Today, while at work, she was called to the bathroom where she was mercilessly teased until she couldn't take it anymore, resulting in a massive orgasm from simultaneous blowjobs and anal play. What surprised him even more was that she had been keeping her boss as a pet all along!
