"Ha, I stopped you!" said Jon as he knocked the stone out of Karyn's hands.
Laughing, Karyn tried to wrestle Jon to the ground. Jon started laughing too, and he wrestled back. Jon started to get very turned on as he rubbed up against Karyn's large, naked breasts and swollen tummy. Jon was quite a bit stronger than Karyn, and fairly quickly managed to get the upper hand. He had her pinned on her back, with him sitting astride her hips. He had her wrists in his hands, and he started pushing her hands to the floor at her sides.
Karyn was giggling so hard that her face was bright red. Jon pushed her hands down, and was now sitting with his shirt touching her breasts and belly, and his face only a few inches from hers. He was laughing nearly as hard as she was.
When Karyn caught her breath, she said "Jon, I have to tell you something..."
"What?" asked Jon.
"I don't think you stopped me," replied Karyn. Jon felt a sudden tingling sensation in his arms and hands. He tried to get up, but instead he fell on top of Karyn. He rolled off of her and tried to sit up. Karyn got up, grabbed Jon's shoulders, and helped him up. Jon looked down at his arms - his hands and arms were gone!
Karyn started to laugh. "Don't worry, they're there," she said, "I just shrank them down so small that you can't see them!"
Karyn grabbed the hem of Jon's shirt and pulled it up over his head in one swift motion. Now he stood, apparently dickless and armless, completely naked in front of Karyn. She started giggling again, causing her large breasts and belly to undulate in a very pleasing manner.
