의붓어머니!!! 우리가 하는 일은 틀리지 않습니다. 아빠에게 말하지 않으면 아무것도 알아내지 못할 겁니다.

It became convenient to have sex in the middle of the living room, with your own stepfather's wife (Stepmother), right after your afternoon bath, and even knowing that your stepfather is at home. The boy asks if that isn't wrong, she replies that no one will know if he doesn't tell her.
