The uncle Suzuna once admired loses his business and his marriage, then withdraws into a trash-filled home. Hoping to help him recover, she devotedly cleans and cares for him, but he exploits her kindness by asking for a handjob. After hesitating, she agrees because she wants to see him regain his energy. His demands soon escalate into requests to lick her body, lick hers in return, and see her in a school-swimsuit-inspired adult costume. As his libido recovers, Suzuna keeps providing sexual relief with a smile, convincing herself that his improvement makes it worthwhile—until his requests lead them even further.
