Incest: A mother who climaxed 73 times in 24 hours

Susumu, who has left his mother Reiko and lives in a shared house in Tokyo, has been waiting for next week's "long holiday" to be held. The reason for this was that during the long holiday, his roommate invited Reiko to his home in an attempt to make the moment he left the house... On the day of the meeting, Reiko arrives at the share house where Susumu lives. Reiko and Sumu open the entrance and silently overlap each other's lips. From that moment onwards, the two of them cum and incest began until the moment Reiko left 24 hours later.
