It's been a long time since Masao's mother let him go on a trip. Accompanying the mother and child was his cousin, Eimi. Due to an emergency, the two sisters arrived at their destination first and Masao's mother arrived the next day. So he got to play with his sister Eimi all day today. Because he was careless, he spilled his drink into his pants. Eimi quickly took him to his room and took off his pants so he wouldn't catch a cold. When he took off Masao's pants, Eimi was very surprised, his cock was extremely large and erect, standing straight forward. Since she hadn't had sex for a long time, it was impossible to leave Masao like that, so Eimi made a bold decision, which was to let Masao have sex with her!!! And then throughout that day, the two always stuck their bodies together, made love and let Masao release all that "bad stuff" inside Eimi.
Good movie here:
