Jun lived a quiet life doing beadwork from home as a housewife. But one day, she was attacked by a man named Kitami who came to collect her work, and her anus was forcibly taken. Since then, during times when her husband and daughter were away, Kitami began dominating her anus. She was filled with enema fluid, forced to suck his cock, and had both holes stimulated with vibrators... Awakening to this pleasure, Jun became increasingly dependent on Kitami. Eventually, she was filled with two cocks, one in each hole, completely enveloped in ultimate pleasure.
