Lara, the stepdaughter of my remarried father, is usually quiet and a very good girl. One day, while her parents were away, Lara caught a cold. I intended to give her cold medicine, but accidentally gave her a secretly used "ultra super erection pill" instead!! Suddenly, she started acting strange... "My body is so hot..." she said, breathing heavily, and then attacked me!! Could it be that the erection pill is taking effect!? In a frenzy, she straddled my penis and began to move her hips wildly, orgasming repeatedly!! Lara's rampage won't stop!
