One night, I found my girlfriend sleeping in bed even though she was supposed to be away, so I decided to lie down beside her against her will. The next morning, I was confused when she became unusually aggressive, giving me an intense wake-up blowjob. When I pulled back the covers, I realized it wasn't my girlfriend at all—but a stunning, unfamiliar woman. She said, "Um... I'm Rima, your girlfriend's older sister," and without hesitation, mounted me in a cowgirl position, riding me relentlessly until I couldn't help but cum inside her. While my girlfriend was away, we spent every available moment having sex. Hard pounding cowgirl, deep oral cleaning, footjobs, vibrator and dildo masturbation with electric stimulators, repeated creampie loads, facial after facial—my reason completely shattered by the irresistible, teasing techniques of the naughty, playful Rima. Completely addicted to Rima, the total opposite of my girlfriend, I fucked her over and over until I'd cum six times. Then, an unexpected truth came to light… A heart-pounding 130-minute episode unfolds.
