The girlfriend's best friend, a naughty teen with a penchant for danger, sneaks into the bathroom, locking the door behind her. She's dressed to entice, her tiny skirt riding up as she straddles her friend's boyfriend. "I know you're not supposed to," she purrs, grinding against his growing bulge, "but I can't help myself. I've seen the way you look at me." She pulls down her top, revealing perky breasts, and guides his hand to her wet pussy. "Just a quickie," she promises, "before she gets here."
