Summary

Chika's body starts producing milk. It causes her breasts to swell unnaturally large. The doctors tell her it's nothing of concern but her chest is tight and it hurts. She begs her father for relief. At first he helps his daughter by using his hands to milk her but it's not very effective so he begins sucking her milk directly out of her breasts. Every day feeling her father gently sucking milk from her breasts is too much for Chika to bear. The forbidden desire erupts in both father and daughter.
