兄嫁セックス ～俺に抱かれるエロい義姉とのエッチ生活～

あらすじ

Minato Kusaka lost his parents at a young age and grew up living with his older brother, Jin. While his life was somewhat lonely, he lived comfortably thanks to the house left behind by their parents and Jin’s support.

Time passed, and Jin entered the workforce and eventually brought home a wife.

Her name was Akari—a bright and kind woman. To Minato, she and his somewhat blunt but hardworking brother seemed like a perfect match.

Minato and Akari eventually became close, maintaining the appropriate boundaries of a sister-in-law and brother-in-law. With Akari in the picture, daily life at the Kusaka household flowed peacefully.

Until he noticed one particular problem.

"You see, I'm feeling... frustrated."

"Because a person's character and good sex are two completely different matters."

...Excuse me?

"So, would you mind helping me out just a little bit? ♪"

Wait, isn't my sister-in-law acting a bit different than usual...?
