The unemployed niece, Xia Yun, falls on hard times and is lured back home by her brother-in-law with a deceitful plan. He pretends to help her, but instead, he ravages her intimate areas with his massive penis, breaking through her tight vaginal walls. Xia Yun's initial shame and struggle soon turn into lustful cries for mercy as she is pounded relentlessly. Her buttocks shake wildly in response, and her nipples are pinched, causing her to ejaculate milk. Her brother-in-law continues to ravage her three orifices until he collapses, exhausted. The unemployment crisis has turned Xia Yun into a sex slave, and her vagina is now exclusively reserved for her brother-in-law's pleasure. This is a story of a deceitful and lustful tale of internal ejaculation.
