KSBJ-360 Mature Woman's Repayment of Favor Chisato Shoda

A man finds a woman who seems to be unwell in a park during the day. The man gives her water and looks after her, and when she feels better she wants to thank him. He is hesitant at first, but gives in to pressure and ends up being entertained at the woman's house. Unable to comprehend the situation, the man is led to a bath to wash off his sweat, but when he starts washing his back, the woman comes in and gives him a blow job. The woman's desire to "repay the favor" escalates even further.
