Minami lived with her boyfriend and lived with her boyfriend's younger brother. One day, while her boyfriend was away, she got a girlfriend for the first time from her boyfriend's younger brother. He isn't there either, so I'll go along with him in special training to cure his brother's explosive habit in any way possible. I love my younger brother who works hard, and only while he's away, I'm going to do a special training to improve premature ejaculation using Minami's pussy.
