Reiko harbored a quiet pleasure between her busy husband and her son Takeshi. It was telephone sex, indulged in whenever Takeshi was away. Today, as usual, she pleasures herself with a vibrator, pretending it's her husband, moaning over the phone. Unaware, Takeshi has been watching her. Pretending the gift is from his father, he presents Reiko with bold lingerie. As she begins masturbating in the new lingerie, Takeshi can no longer hold back. Standing before her, he screams, "It's not your absent husband—it's me who'll make you feel good!!!"
