Next, it was Karyn's turn. She played a card that said "10% Height".
"Oh, I have that one!" said Zoe, tossing it into the pile. Jon sighed, and noticed that everything in the room looked a little bigger.
"At least it's only 10%," he said, "That's not too bad."
Zoe looked at him. "How tall are you, Jon?" she asked.
"Five foot ten," he replied in his high, girlish voice.
"Well, that means you're around five foot three now, which makes you about an inch shorter than me," she said, smirking.
Jon glowered, but didn't reply. Zoe looked at her hand, and played a card that said "Underwear".
"Shit!" said Jon and Karyn together, as neither could counter it, and they were both naked already. Karyn flipped over a card that said "20% Butt Size" and she craned her neck back, trying to see her widened rear end. Jon flipped a card that said "2 inches penis length", and Zoe started laughing before he could cover it up.
"Oh my God, Jon," she said, "It's so tiny! It reminds me of when we were little kids and would bathe together!"
Jon felt the tiny, soft nub of a penis under his hand, and it pressed into his clitoris as he covered his crotch. It started to stiffen at the strange, pleasant stimulation.
Karyn and Zoe stared at him, expectantly, and Jon felt his cheeks flushing. "What?" he said, "I don't really want my sister and my girl... I mean, good friend staring at my junk!"
"It's your turn, Jon," said Karyn gently.
"Oh," John said, pointing at the cards lying face down beside him. "Can you just play one of my cards for me?"
"Sure," said Karyn, leaning across him to grab a card. Her nippleless breast brushed against Jon as she leaned, and he saw her big, curvy ass pointing up in the air, and his tiny cock stiffened even more.
Karyn put Jon's card face up between them. It said "Shirt", and Karyn said "Yes, I have that!".
Zoe's t-shirt vanished, leaving her A-cup breasts hanging in the open, since she didn't have a bra. She covered them up reflexively, then dropped her hands. "I guess there's not much to cover up anyway," she said, looking at the small bumps with no visible nipples.
Jon tried not to look. He didn't really want to look at his little sister's boobs, even if they were blank. So, he wasn't watching when Zoe played a card that said "Handcuffs", and his wrist dropped unexpectedly, grazing the headboard.
"Ow!" he said, rubbing his right wrist, finally freed from the padded handcuffs.
"I guess it meant two inches hard," giggled Zoe. Jon quickly covered his crotch again, but he saw that she was right. His erect penis was smaller than his little finger.
