Teen girl Melissa Moore begins to receive anonymous phone calls from a stranger, who does nothing but breathe into the phone. At first, she is creeped out by the calls but, as they keep happening, she realizes that it's probably just her boyfriend playing a joke on her. So, she starts to talk back to the 'stranger,' playing along, and threatening to find him and expose him for being a pervert ... referencing the fact that she knows who he is! But, no matter how much she eggs him on, he never speaks or reacts. She begins to anticipate his calls and fantasize about their roleplay ... even masturbating about it. Finally, after her parents have gone to bed, she challenges him to show himself. If he can sneak into her house and confront her then he can do whatever he wants ... even fuck her. When the 'stranger' hangs up abruptly, the girl assumes her boyfriend's game is over. When he sneaks into the house and catches her in her bedroom, she is shocked that he actually showed up (in a mask no less) and she happily submits to him, getting off on the experience and going along with the roleplay. In a very primal sex scene, he takes her from behind and fucks her against the wall, on the stairs, harder than they have ever fucked before, and right under her parent's noses! After an intense orgasm, the masked stranger leaves as abruptly as he came. The exhausted teen can't believe how intense it was, as she lays in her dimly lit room. Her phone rings. It's her boyfriend. 'I can't believe you,' she says. 'That was so hot! How did you come up with that?'
