He was locked up in the bathroom and left alone with his sister-in-law! It was cold so I was soaking in the bathtub together, but couldn't hold it in and fucked her all the way through the morning!

I live at my older brother's house to take the entrance exam for a university in Tokyo. But I can't concentrate on my studies as I want... The cause was known. Because my brother's wife... Nanami has. She's kind, cute and stylish... I was punished because I was thinking about this kind of thing. The bathroom door was poorly built so it didn't open from inside, so I asked Nanami to open it from outside... and Nanami came into the bathroom with too much energy. But we both couldn't leave...
