Hello, there are no games like true husband, seduction, sex education guidance, sex science popularization for less experienced girls. Especially in which he has sex with his wife, and his daughter watches and learns to develop a relationship

She is not his daughter but his wife's daughter, with her being over the age of 18 she is not even his step-daughter.
If she was living with her mom at the time they got married then you can count her as a step-daughter.

They love each other and enjoy life together. But everything changes when a young girl appears on the main character's doorstep, who appears to be his wife's daughter.

For me I do not count this as incest.
