Karyn in Jon's body held up the piece of paper Jon had written before. It read: 'I wish Karyn's breasts would gradually get bigger.'
Karyn was still laughing; the laugh sounded so strange coming from his own body. "I guess you'll get what you wanted. Let's see how big they'll get."
Jon almost said 'gumdrop' immediately, but he didn't want to give Karyn the satisfaction of winning that fast. "Aren't you embarrassed by having me in your body?" Jon started to play with her breasts, causing him to blush. "I can do whatever I want."
"Oh, I knew that when I made the wish," Karyn said. "Just know, I can do the same thing to you." She put her hand in her pocket with a sly grin. "Besides, I think you're more embarrassed than me right now. Oh, I think they are getting bigger."
Jon looked down. He felt something warm flow into his breasts. They began to press against his bra. It was impossible to feel pain because of the rules on the stone, but pleasure was a different matter. He felt chemicals in his body stir his emotions as his breasts grew bigger. A gasp escaped his mouth.
"Oh," Karyn said. "So that's what it feels like." Jon looked at Karyn; her smile was gone, but her hand was still in the pocket. Her eyes were glued on Jon.
"Don't tell me . . ." Jon started, but another warm sensation ran through his chest. His breasts began to swell and more chemicals ran through his body. Then, it happened again, and again. Each time, Jon couldn't prevent a subtle moan escape his mouth.
"I, uh, I need to go," Karyn said. She ran out of the room to the nearest bathroom. Jon barely noticed she left.
Jon tried to get himself to say the word; he had lost completely. However, the warm sensation returned with more swelling to his breasts. It felt so good; he couldn't say the word. Each time, the pleasure increased, being more sweet than the last. His breasts were pushing tightly against his bra; he didn't feel pain, but he did feel the pressure. He reached behind him unclip the bra. Sweet release.
His breasts were the size of his head and still growing. He had to lay down on his stomach to ease the weight. It felt like two warm pillows underneath him. He wondered how much more of this he could take.
