Overview

After recovering her breasts, Ouka goes to a hot spring to relax and play with her newly found bosom. However, she gets caught by Kagefusa and Kaede, who blackmail her into capturing Chifusa and hold her in place so that Kaede and Kagefusa can suckle on her breasts in an attempt to suckle her milk which, according to the Manyuu Scroll, would enlarge their own breasts.
