A small party between my father and grandson was held at Maki Houjyo's house. It wouldn't be worth mentioning if this was just a sweet party, but during the party all three of them invited each other to drink. When they had drunk a few cups, they began to invite each other to play with each other and take off their clothes and of course the aunt lost, so she had to take off her clothes to give the two nephews a stimulating feeling. Unable to control herself, the aunt took the initiative to do it with her two biological grandchildren, the two grandchildren, due to the stimulants in their bodies plus their lustful nature, also indulged their aunt's wishes.
