The older brother took a young wife, while the younger brother was shown his sister-in-law's fair skin and large breasts. The sister-in-law was dissatisfied with sex with her husband, creating an opportunity for the younger brother to take advantage. When the older brother was not around, he forcefully approached her. Though she resisted, the sister-in-law had a masochistic personality and the younger brother could no longer hold back, thrusting his erect penis inside and raping her relentlessly. Despite being raped, the sister-in-law felt intense pleasure in her beautiful body.
