[Sekki Kettle Jidai (Sekki Kettle)] Poisoned Princess [Kani-sama]

A smug witch known as Puffin-sama administers 'magic healing' to Princess Aria, sniffing and slurping at the busty girl's body under the pretense of drawing out a curse—and with it, all of Aria's knowledge, power, and experience. Spiraling under hypnosis, Aria eagerly sucks down the treatment, only to be engulfed and assimilated by Puffin's slime-like flesh, reborn as a futanari clone devoted to spreading the same 'healing' to others. Declaring the king's lack of healing magic the source of the kingdom's suffering, the newly merged pair sets off for the royal capital on a quest to heal all humanity.
