Nikki Mars, the college girl with an irresistible big ass, is on the phone with her boyfriend, her voice low and sultry as she describes the naughty things she'd like him to do to her. She's spread out on her dorm room bed, fingers tracing circles around her clit, her pussy dripping with anticipation. Her other hand is busy, pushing a thick dildo in and out of her, simulating her boyfriend's cock. The phone sex heats up, Nikki's body writhing, her ass bouncing as she fucks herself harder, her moans echoing through the room.
