YSN-481 My sister-in-law is a delivery health worker Kanna Shinazaki

A man who hadn't called a delivery health service to his home in a while. He felt like he had seen her somewhere but couldn't quite remember. 'She looks like my real brother's fiancée,' he thought, and then, thinking 'no way,' asked for her photo... Sure enough, this delivery health worker was his brother's fiancée and was scheduled to get married next month. The perverted, sadistic younger brother gloated and used this as a reason to blackmail her, playing with the woman who would soon be his sister-in-law like a toy, thoroughly enjoying impregnation sex.
