My girlfriend and I have been living together for a while. Tomorrow she will be traveling with her family for four days. My girlfriend has an older sister named Saeko, and she came to play with us today. Because she was busy at work, Ms. Saeko could not accompany the whole family. But that night, I was sleeping when I was woken up by... Saeko sister is sucking my cock! And the next day, when my girlfriend and Saeko left, I was at home lazily lying on a chair when someone rang the bell. And indeed Saeko. Unable to resist her beauty and invitation, I frantically fucked her exactly what she wanted! And during the four days my girlfriend was away from home, she and I were like a couple in love, all day after eating and fucking, I was also allowed by her to cum in her uterus. And I thought this relationship would end after my girlfriend came back, but no, she came forward and kissed me on the lips, as if to say, our relationship will continue...
