The first son, Shijuji no Tsugumi's mother, Tatsuo TOKUNOMITSU, who was thirsty for his son-in-law and starved for love, but only his husband didn't know about him; a family member of the hole, Ikariko.
The man he loved was a man with two big sons. She became a new family in a difficult position as her stepmother. The sons, who are still in the process of talking to their sons while feeling a subtle distance from them, gradually open up their minds and have an forbidden physical relationship with their family members. A thick and sluggish meat stick that does not fit in the mouth penetrates a ripe butcher into the mouth and exchanges hot mouthing, an forbidden thick sex child cries out with a sweet voice.
