A friend who came up to Tokyo from the countryside brought his girlfriend and her sister. The man saw his friend pursuing his girlfriend in a bedroom where four of them were sleeping at night. However, after ejaculating, the friend ignored the frustrated girlfriend and fell asleep. Unable to hold back any longer, the man waited until the boyfriend had fallen asleep and then made advances on the girlfriend and her sister, who had woken up and was watching from beside him. This time, he thoroughly enjoys a double sister serving with continuous internal ejaculation.
