One day, Karen was suddenly abducted and taken to a place that outwardly operated as a restaurant called "Chon no Ma". She was subjected to nipple training to become their star attraction and keep making money. Despite her dwindling mental state, her sensitivity increased day after day through relentless nightly training, ultimately leading Karen to become a nipple slave at Chon no Ma. Word of mouth spread, drawing men to the red-light district, where they lined up to exploit her now-clitoris-like nipples, relentlessly fucking her at a high rate! Just when she thought she was done, more men would join the queue, re-inserting and creampieing her again and again!
