Tsubaki spends the night with her husband for the first time in a while. She wanted to do it one more time, but her husband was too tired to go any further. The next day, Tsubaki went to wake up her son. When I turned over, I saw my son's enlarged crotch and swallowed my saliva. That night, Tsubaki smells her son's pants while taking a bath. He masturbates in the fantasy of being attacked by his girlfriend's son. One day, Tsubaki was in the kitchen.
