"Alright," said Jon, still not used to his feminine-sounding voice, "I've had enough. Let's clean up."
"No!" Zoe exclaimed, "I've barely had a chance to play! Let's do a few more turns."
"That's easy for you to say, Zoe," said Karyn, "You've hardly had any changes. Look at your poor brother - he's naked in front of his sister, and he looks and sounds like a girl except for an embarrassingly tiny hard-on. You, on the other hand, are topless with boobs that are rated PG, and otherwise perfectly normal."
Jon glowered at Karyn's comment about his penis, but he could hardly disagree. He didn't know whether it was worse to look like this in front of his sister, or his best friend (who just might be a lesbian).
"Okay," said Zoe, "What if I strip naked and play with my cards face up? Then can we play a few more rounds?"
"I don't want to see you naked!" said Jon, but Karyn interrupted by saying "Alright, how about you do that, and we play two more rounds?"
"Sounds good!" said Zoe, whipping her pants and underwear off in one swift motion. She laid her card in front of her - they said "Pants", "Bra", "Hair", "Pussy" and "Tattoo". "It's your turn, Jon!" she said brightly.
Jon looked at his cards and thought for a moment. Then he played one that said "Eyeglasses".
Neither Karyn nor Zoe could counter it, so they each flipped over a card. Karyn's said "10% Height", and she returned to very nearly her original height. Zoe's said "Tail", and she gasped as a long, smooth tail grew from her tailbone and started to sway back and forth behind her.
Karyn put down a card that said "Body piercings". Again, neither Jon nor Zoe could counter it. Zoe flipped over a card that said "Cat ears", and two twitching cat ears poked through her hair on the top of her head. She reached up and felt the sides of her head, but her regular human ears were completely gone. Jon flipped over a card that said "2 Cup Sizes" and saw his breasts grow to become nearly as large as Karyn's had been when they started playing.
Zoe looked at her cards, and played the one that said "Pussy". Jon couldn't counter it, but Karyn triumphantly threw down a matching card from her hand. Jon felt his vagina vanish, leaving smooth skin where his balls should be. Zoe drew a new card and put it face-up with her hand, and it said "Feathers".
Jon quickly played a card that said "Moustache", and neither of the girls could counter it. Karyn flipped a card that said "2 breasts", and gasped as two breasts sprang forth from her chest underneath her C-cups. The new breasts were slightly smaller, and were topped with small nipples. Zoe flipped a card that said "Fur", and a thin coat of soft brown fur appeared over her entire body, including her face.
"I changed my mind, I don't want to play anymore," said Zoe, looking at her furry body.
"Too bad, we agreed to two more rounds," said Jon. "You and Karyn each have to play one more card."
Karyn laughed, and put down a card that said "Feathers". Zoe countered it, and drew a new card that said "20% Height". Jon couldn't counter it, and flipped over another card. This one said "20 pounds of Belly Fat", and Jon's belly ballooned outwards. His belly stood firmly out from his body, pushing his large breasts up and out. Because he remained thin everywhere else, it made him look like he was pregnant.
"My turn," said Zoe, and played her card that said "20% Height". Karyn and Jon both shrank down to a little over four feet tall.
"And that's the game," chirped Jon, who looked like a tiny woman who was nine months pregnant with twins. He started to pick up the cards, and Karyn and Zoe helped. They put the cards away, but nothing changed!
Jon looked up and saw that Zoe was standing, holding one last card high above her head. "You missed one, shorty!" she said. Jon jumped up and tried to reach the card, but he was too short, and his massive boobs and belly threw him off balance. He fell to the floor, and both Karyn and Zoe laughed and laughed. Finally, Zoe handed the last card to Karyn, who tucked it back into the deck.
Jon and Karyn were suddenly returned to their normal selves. Zoe was normal, too, except that she was standing naked from the waist down. She was halfway down the hall to her room when she came running back to get her pants and panties. Before she left again, she said "Jon, can I borrow that game some time?"
