We disguised ourselves as a volunteer group and conducted an investigation! We found a woman who was having trouble with her husband's stepchild! We called her stepson on the spot and got her to join us. The situation did not improve through discussion, so we suggested that they have some skinship through sex. The mother was confused, but she started to take off her clothes... In the end, the staff held down the stepson's waist as he tried to ejaculate outside, and made sure he ejaculated inside her.
