A perverted boss targets a shy, huge-breasted office worker with humiliating sexual harassment. He mocks her erotic breasts, squeezes them hard, and toys with her stiff, hypersensitive nipples. Watching her twitch and struggle to endure it drives him out of control, so he keeps twisting and training them until nipple stimulation alone makes her cum. Oil, slippery rubbing, and sex toys push her sensitivity over the edge until she orgasms and urinates. He then drives a thick cock into her while stimulating both penetration and nipples, overwhelming her reason with pleasure until she submits and begs to be used as her manager's personal nipple toy.
