HMN-396 I accidentally saw my sister-in-law, who is in a dull period with her husband, masturbating in the shower... She was soaked from head to toe and we fucked like crazy!! Endoh Jun

For the university entrance exam, I went to Tokyo and stayed at my brother's house. My brother and his wife Jun seemed to have a good relationship, but lately, my brother has been coming home late, making Jun unhappy. 'In the beginning of our marriage, he used to say let's take a bath together every day.' One day, I saw Jun looking lonely while masturbating in the bathroom, and excited, I couldn't hold back as my dick stood at attention and I charged into the bathroom! From that day on, we had sex multiple times, soaked wet, with me ejaculating inside her.
