Maina Miku lives with her mother and starts a part-time job assisting their wheelchair-bound landlord when her mother falls ill. However, the lustful landlord begins making unreasonable demands, eventually forcing her to handle his underwear and other intimate tasks. Unable to refuse, Miku is coerced into giving handjobs, titty fucks, and deep-throat blowjobs, and ultimately raped with creampie sex. As the landlord's depraved acts escalate, Miku, who initially resisted, gradually succumbs and accepts her role as his sex slave, cumdump, and obedient servant.
