"Stamina," she decided. Immediately she felt her body grow cool as her skin began to harden all over her body. An ache in her tailbone warned her that she was about to gain an extra appendage, and she frantically undid her dress, leaving her clad in her underwear, which she immediately tried to pull off as black scales began to cover her arms and legs. Her fingers went slightly numb, but remained, and her canines ached and extended as her skull grew flatter and her chin disappeared, leaving her new fangs to protrude past her bottom lip.
Millicent finally succeeded in pulling her bra off - Jack whistled at the sight of her naked breasts, but sighed as they rapidly began to flatten out. Millicent felt her tongue tear in two, becoming forked, as a long scaly tail emerged from her posterior and her eyes became yellow slits. She carefully inspected herself, noticing that even though she was obviously a black anthropomorphic snake, she had retained her legs and instead developed a tail. "Where'd your boobs go?" Jack moaned. "Snakes are reptiles. They don't have breasts," Trixie snorted.
"We should probably all undress," the snake girl recommended. "Whatever this is, it's serious and doesn't care about modesty,"
"No way," Nick frowned. "I'm with the geek," Trixie nodded, but blinked in surprise at the fact that Kasey was already pulling her pants off. "Okay," she innocently smiled, and Jack grinned. Trixie facepalmed as Millicent handed Jack the dice. "All yours, lover boy,"
Still staring at Kasey's bra, which she was in the middle of unwrapping, Jack absent-mindedly rolled the dice.
