The older brother is successful while the younger one (Yuuya) is less than his older brother. Yuuya goes out at night to have sex and after some time he stopped having sex with women. He goes to a shop called hole in the wall. The receivers ass is displayed through the wall so that the customer can have sex with it as they like. The receivers face is not shown. Anyway, one day Yuuya notices while thrusting into a ass that the mole on this persons wrist is similar to him older brothers.
