An office lady staying at a business hotel due to work lies down on the bed in her pantyhose and calls her boyfriend. What starts as casual conversation gradually grows more intimate, eventually turning into phone sex. The distance between them seems to heighten the erotic tension, as she rubs her crotch through the pantyhose, creating the atmosphere of having sex across the phone line. Her excitement builds uncontrollably, producing clear sounds of arousal and moans. She becomes increasingly passionate, so overwhelmed by desire that she worries her colleague in the next room might hear her.
