[Kirisaki Byakko] Echidna-sama no Himatsubushi 2 Ch. 4 (COMIC Reboot Vol. 31) [Tigoris Translates]

A bored dungeon ruler lounges at the heart of her lair while a witch adventurer ventures below, only to be swallowed, melted, and remade into a slime girl through gooey, absorbing corruption. Transformed but not lost, she returns home to her sickly shota brother, trading what she lost in the depths for a new body whose healing powers come with a hunger only family can satisfy. What follows blends slime transformation and incestuous treatment into one indulgent, tenderly wicked sibling affair.
