While cohabiting with my girlfriend, I went back to her parents' place for two nights and three days. What was waiting for me was a sister with a plump, massive ass! Even though I felt bad about my girlfriend, I couldn't resist the temptation of the giant ass and ended up continuously pounding and ejaculating inside... She kept pressing against me like a pile driver, so I grabbed that massive ass and fucked her hard, ejaculating inside! Her sister's libido seemed to be malfunctioning; her plump, massive ass was about to crush me as she went into heat!
