Because he's been so busy lately, Masaru hasn't had the chance to make love with his lover. After much begging, she agreed, and when her work was less, she would indulge him. When he got home from work, Masaru saw someone lying on the chair, hanging out his T-back underwear. Thinking that his lover was about to pamper him, Masaru couldn't control himself anymore and rushed to fuck her. After a while, he realized that this was not his girlfriend but Himari, her older sister!!! It turned out that Himari was arguing with her lover, so she came to stay at their house. A moment later, when Masaru went out to the living room, he met a naked person wrapped only in a towel, showing her butt towards him! Thinking that it must be his lover, Masaru immediately jumped in and fucked her. But he was wrong again, this was still Himari who had just finished bathing! Even so, Masaru couldn't stop and poured all the sperm he had accumulated for so long into Himari. While thinking about how to solve this problem, Himari approached him, seducing him, wanting him to ejaculate inside her even more.
