My beloved wife and I had our first child, and we were so happy... but she suddenly became cold and mean. It was the postpartum slump. She complained every day and refused to have sex with me, and I was at my limit. That's when my wife hired a babysitter, Ichika, to help her return to work. She had a strong maternal instinct and lured me, who was weak, to her big breasts, and healed me. Even though I knew it was wrong, I indulged in her breasts and had creampie sex. After each 15-minute feeding, we hid and breastfed and inseminated each other over and over again. I forgot about my wife and drowned in her.
