The Umbra Witch is an adult transformation comic by KannelArt (Patreon.com/KannelArt) — a shady amulet promises magic powers, and instead turns two guy friends into two seriously hot witches.

Story: A guy shows off a strange amulet a "shady guy" sold him, hoping it will actually give him magic powers. He is the one who paid for it and risks touching it first, expecting nothing to happen — but it is his bespectacled friend standing next to him who ends up wrapped in living black tendrils a second later. Freaked out and thrilled in equal measure, the friend transforms into a towering, curvy Bayonetta-style witch, complete with a hair-woven battle dress and heels, and a much sexier voice to go with the new body.

Hoping to undo it, she grabs the amulet again — instead of reversing the spell, it strips away the witch form and leaves her a completely naked, human-shaped girl, powers and all. Between the panic, the nosebleeds, and a very reluctant search for spare clothes, she cannot help getting distracted feeling herself up, admitting the first pair of tits she ever got to see turned out to be her own. When her friend barges back in without knocking, having grabbed the amulet himself out of curiosity, it turns out he did not get away clean either — a second, white-haired girl struts in, more than happy to "join" whatever fun her new friend is having with herself.
