Because she has been so busy lately, Yui Nagase hasn't had the chance to make love to her lover. After much begging, she finally agreed, saying that when work eases up, she will indulge him.

When he got home from work, Yui Nagase saw someone lying on the couch, her T-back panties hanging out. Thinking that her lover was about to "indulge" him, Yui Nagase couldn't hold back anymore and rushed to fuck her! After a while, he realized that this wasn't his girlfriend but Yui Nagase, her older sister!!! It turned out that Yui Nagase was arguing with her lover so she came to stay at their house.

A moment later, when Yui Nagase went to the living room, she saw a naked person wrapped in only a towel, showing her pussy to him! Thinking that it must be her lover, Yui Nagase immediately rushed to fuck her. But he was wrong again, this was still Himari who had just finished bathing.

However, Yui Nagase couldn't stop and poured all the sperm he had accumulated over the years into Yui Nagase. While he was thinking about how to solve this, Yui Nagase approached him, seducing him, wanting him to ejaculate inside her even more...
