In 'Papa datte, Shitai', lonely single father Keiichi Naruse hires college student Koya Asumi as a housekeeper, unwittingly inviting a torrent of pent-up lust into his home. Koya, immediately infatuated with his handsome, stressed-out employer, discovers Keiichi's hidden stash of porn and seizes the opportunity. What begins as a bold, nonconsensual advance on a sleeping Keiichi quickly spirals into a raw, secret affair. Their relationship is built on stolen moments of intense fucking; Koya relentlessly tops Keiichi, using his mouth, hands, and cock to provide the 'sexual relief' the desperate father craves. The series chronicles their journey from a purely physical arrangement, filled with hard, explicit encounters in every room of the house, to a complicated romance where cock-sucking blowjobs and ass-pounding sessions become their primary form of communication and affection.
