Andrew felt the same transformational liquidy feeling in his face. As he was about to mention this to Candy, he found he couldn't open his mouth! His lips were fused together, and he could feel the inside of his mouth melting and contracting, changing into something else. Candy looked on in terror, past her newly udderlike breasts. He really hoped his suspicions were wrong, but the look on her face told him otherwise.
His teeth, tongue, and most of his jaw liquefied and transformed into tightly wrapped muscle, squeezing instinctively as he tried to scream. His nose also melted and joined the swirl of transformation. Finally his skin parted again, but vertically. Where his nose had been a sensitive fleshy nub grew in, and overwhelming sensations blasted through Andy's face until it was covered by a neat hood of skin. his former mouth didn't quite gape, but he could feel it slightly open as his new lips formed. He took a few ragged breaths, realizing he'd been holding it, and noted with dismay that the air passed through a hole at the base of neck-- a stoma.
Candy spoke up in wonder and shock. "That's my... my pussy. It even has my clit-ring." Andy did notice a curved barbel passing under the sensitive nub, and trying to move his mouth sent shivers all through him.
Suddenly, their discarded clothes decided to return, Candy's familiar halter top and short leather jacket re-clothing her and Andy's t-shirt and hoodie doing the same. Both her pants and his skirt vanished, but her sexy red panties flew and Andrew's face. As he thrashed around to get it off it reconfigured into a sort of panty-mask with straps behind his head.
As the changes finished, there was a slight clatter as a wheelchair appeared in the corner of the room, with sort of a footrest sling that would support Andrew's armless body.
