Deciding she didn't want to risk becoming any more canine, Mary shifted on the couch and grasped the mug with it's sloshing contents. Bringing it to her mouth, she opened her muzzle and tried to tip the liquid into her mouth as she would normally have done. Unfortunately, with her longer jaw and changed tongue, some of the elixir dribbled out the side of her maw, running down her neck and chest.
"Shoot!" she thought, lapping at the last drops inside the mug with her long tongue. "Well, I think I got most of it, other than that little bit." She could already feel her tongue shrinking, and she realized that her muzzle had retreated partway back into her face, growing shorter as her eyes crossed trying to keep her nose in view.
Looking down, she watched as her legs lengthened, her thighs plumping with muscle as they returned to human proportions. As they bulked larger and thicker, confusion spiked when Mary noticed wiry hairs pushing out, until she remembered that she was now male, so her return to humanity would reflect that. Her toes shifted as the arches of her feet shortened, though they remained larger than her previous Woman's Size 7.
A deep giggle escaped her, "I'm gonna need a whole new wardrobe!"
Mary reached up to feel a light stubble on her jaw, all that remained of her furry face. Tracing her fingertips over her features, she felt her wide mouth with its slightly plump lips and her now-fully-human nose with the new arch she'd glimpsed earlier in the mirror. Her brows were definitely more prominent than they'd been when she was female, as well as bushier, and she could feel that her ears had returned to normal on the sides of her head.
Rising, she walked back to her bathroom to view herself (himself?) in the mirror. Mary saw that her hair had grown back out, but had stopped at a short, boyish length. She admired her strong shoulders, flexing a little and marveling at the strange reflection staring back at her.
