"Fuck," she whispered. "Okay. Uh, I guess I'll pick up a red card, a blue card and a yellow card."
She flipped over the red card first. "Snake girl/lamia." She writhed in pain as her spine began to lengthen, her legs fusing into one powerful, long muscle. It grew longer and longer, a fleshy extension of herself that wrapped around the entire group twice before coiling under her and keeping her upright. Hailey groaned as a layer of red scales, complementing her red hair, covered her whole eight-foot tail. She ran a hand through her sweaty hair.
"Okay, that was... a lot. Blue next."
She held her breath as the blue card was flipped.
"Double arms? What does that mean?" she asked, oblivious to the slowly swelling bumps under each of her arms. She crossed all four of her arms over her chest, startling as she felt the sensations from all of them. "Oh shit, that's weird."
She started experimenting with them, moving each one independently. Using one of her new appendages, she flipped over her final card. The yellow one.
"Double muscle, double height." With a groan, her whole body began to stretch and contort. Her tail coiled another three times as it became sixteen feet long. It began to bulge grotesquely in places as it grew thicker and stronger, and Hailey involuntarily flexed from the pleasure. Her three-foot torso became an athletic, proportioned six foot torso. If Hailey had still been human, she would have towered over her friends at a massive ten feet, but she supposed that she could still tower over them with her huge coils.
Speaking of, she slithered around a little, settling herself in a more comfortable position, Jen pressed up against her side. Her tail, thicker than Jen's leg even at its end, wrapped around her new shaft and then back down, prodding at her opening. Hailey smiled devilishly as she used her impeccable control to massage the new member with her fantastic muscles. Jen bit her lip to stop herself crying out, but it seemed her girlfriend wouldn't relent.
Hailey lowered herself to Jen's level and pressed her lips firmly against hers. She could feel Jen moaning into her mouth as her flexes grew faster and more intense around her new cock. Feeling her little girl come to the brink, Hailey made a last assault by plunging her tail deep into Jen's pussy. With a barely-contained groan, she came from both genitals at once and fell into the dazed stupor of the afterglow.
Satisfied, Hailey released her and sat back.
