The birth of his first child should leave him overjoyed, but his wife becomes cold during a postpartum rough patch, constantly criticizing him and refusing sex. When she hires Ichika as a sitter before returning to work, the maternal, busty woman comforts the exhausted husband against her breasts. He knows it is wrong, yet gives in and creampies her. Every time his wife spends 15 minutes breastfeeding, the pair sneak away for another rushed, unprotected breeding session until he forgets his wife and loses himself in Ichika.
