One night, my girlfriend was supposed to be out, but she was asleep in my bed, so I slept next to her. The next morning, I was wondering why she was being so aggressive, but she woke me up and gave me a blowjob. When I turned over the covers, I saw that it wasn't her, but a beautiful stranger! I was confused, but she told me, "Um... it's my sister, Rima." And then, Rima got so into it with her cowgirl position that I ended up cumming inside her... And so, we spent the limited time we had until she got home, all having sex... Cowgirl position, intense body-washing blowjob, footjob, electric massager and vibrator masturbation, multiple creampies, facial... Rima's mischievous, slutty techniques completely destroyed my reason. I was hooked on Rima, who was the complete opposite of my girlfriend, and we fucked so hard that I cum a total of six times! And then, I discovered something unexpected... 130 heart-pounding minutes.
