The birth of his long-awaited first child should make him happy, but his wife becomes cold during a postpartum slump, criticizes him daily, and refuses sex. When she hires Ichika as a sitter before returning to work, the maternal, busty woman pulls the exhausted husband against her breasts and comforts him. He knows it is wrong but gives in, fucks her bareback, and creampies her. Every time his wife spends 15 minutes breastfeeding, the pair sneak away for another rushed breeding session until he forgets his wife and loses himself in Ichika.
