[Manga] Ore ga Mita Koto no Nai Kanojo

A guy brings home a girl who has a hidden past, which, by coincidence, is well known to the guy's father. And he is not going to miss the opportunity to use this information, because once the dad used the services of his son's new girlfriend, and now he is not averse to reliving the old days, this time without paying for services.
