[BF-567] Secretly having an affair with his girlfriend’s sister day and night with no way out

A secret sex movie of Saeko Matsushita My girlfriend and I have been living together for a while. Tomorrow she will go on a family trip for four days. My girlfriend has an older sister named Saeko, and she came to visit us today. Because of work, Saeko couldn’t come with the whole family. But that night, while I was sleeping, I was awakened by… Saeko sucking my cock! And the next day, when my girlfriend and Saeko left, I was lazily lying on the couch at home when someone rang the doorbell. And sure enough, it was Saeko. Unable to resist her beauty and invitation, I fucked her like crazy just like she wanted!

And I thought this relationship would end after my girlfriend returned, but no, she came forward and kissed me on the lips…….
