My girlfriend refuses sex unless I wear a condom. I thought our overnight date would finally be different, but she still says no. While I am desperate for raw sex, her older sister flashes her huge tits and seduces me—and even offers to let me cum inside. I love my girlfriend, but right now all I want is bare sex. Once I discover the pleasure of creampieing her sister, I secretly fill her again and again. My girlfriend eventually catches us, but I no longer care. All roles are performed by adults.
