経営難にあえぐ某所レンタルルーム経営者まひろ。ある日クレームが入り対応していると、汚オジにお小遣いをもらう。言われるがまま全身舐め掃除をすると満足したようでまた来店してくれるという。抵抗はあったもののその興奮を忘れられずにいたまひろは、経営の為と自分に嘘をつき客との快楽の時間にふけていくのだった――

Mahiro, the owner of a rental room in a certain location, is struggling financially. One day, she receives a complaint and, while dealing with it, is offered pocket money by a dirty old man. She does as he asks, licking him clean all over, and he seems satisfied, promising to come back again. Although she initially resisted, Mahiro couldn't forget the excitement, and lying to herself that it was for the sake of her business, she indulges in pleasure with her customers.
