I, Nanami Hinata, have a secret hobby... which is to masturbate on the washing machine on my balcony! One day, while I was enjoying its perfect vibrations, the washing machine broke... I had a repairman come immediately, but it was my ex! In order to masturbate on the washing machine again, I had no choice but to ask him to repair it... But during the repair, the washing machine goes haywire! The corner of the washing machine digs into Nanami's vagina more intensely than usual, making her drenched. Her pleasure was noticed by her ex, and the ex started to touch her body... The ex, who knows every inch of her, fondles her everywhere, even touching her insides, making Nanami reach her limits... "Stop it! We've already broken up...!"
