"May I try it?" Karyn asked.
"Sure!" said Jon, excited to see what she was going to do.
Karyn took the funnel, and set it beside her. She reached her right arm inside her shirt and pulled her bra strap over her arm, then put her arm back out her sleeve. She repeated this with her left arm, then reached her hands under her shirt and twisted the bra around so that the clasps were at the front. The. She undid the bra and pulled it out under her shirt.
Jon tried not to stare, but he kept finding his eyes drawn back to Karyn's chest as she wrote on the funnel and adjusted the switches. He could see her nipples poking through her shirt, and was surprised to see that her large breasts had very little droop or sag to them. For their size, they were extremely perky. Karyn noticed Jon's wandering eyes, but she just smiled slightly and said nothing. In fact, she may have set her shoulders just a little further back to make her tits stand out even more.
Karyn finished adjusting the funnel, and dropped her bra through the top. Nothing came out the bottom, but the funnel was empty.
"Who did you give it to?" Jon asked, but he knew the answer before he was done speaking. He felt a sudden weight on his chest and the pull of straps on his shoulders and back.
"Karyn!" exclaimed Jon as he looked down. Two large, soft mounds stuck out under his shirt, held in place by the 34E bra that Karyn had dropped in the funnel. She held the funnel up, laughing, showing him where she had written his name on the side.
Jon grabbed his new tits. He was surprised at their weight - they were soft but firm, and hung heavily on his chest. The straps dug painfully into shoulders that had not had time to become accustomed to wearing a bra.
"Give me the funnel!" Jon demanded. Karyn was laughing too hard to answer, but waved her hand in a gesture that showed she wasn't about to hand it over. Jon turned and touched the stone.
"I wish that I had another device, identical to the one Karyn is holding!" he said. Another funnel appeared in his hand. Jon started writing his own name on the funnel.
Karyn got hold of herself, reached over, touched the stone and said "I wish that the funnels cannot be used to change yourself. I also wish that this stone won't grant any more wishes until this time tomorrow!"
Jon groaned. "Karyn, come on! You can't leave me with these!" he said, gesturing at the boobs tenting out his shirt. They were so big that they lifted his shirt and showed the sparse hair on his stomach. "They're so heavy they hurt!"
"Don't complain to me about how they feel," Karyn said, "I know EXACTLY what they're like. You might be a bit more comfortable if you take the bra off though. Mine feel better this way, at least as long as I'm not walking or running around."
Jon tried to take the bra off as Karyn had, but he couldn't manage it. He was going to have to remove his shirt first.
"I can give you a hand," Karyn offered, but Jon refused.
"What?" Karyn said, "it's not like you have something I haven't seen before..."
"Please," said Jon, "if you won't let me fix this, at least give me some privacy for a few seconds."
Karyn said, "Okay, I need to use the bathroom anyway." She walked out of the room and closed the door, leaving her funnel behind.
As soon as the door was closed, Jon pulled off his shirt and removed the bra. He stared down at his new breasts, with their surprisingly prominent nipples. He stared at them for a minute until he heard the toilet flush. Then he leapt to his side table. He opened a drawer and started digging. He pulled out a package of condoms, wrote Karyn's name on the funnel, and dropped them in. Almost immediately, he heard a shriek from the bathroom, followed by rapid footsteps towards his door.
Jon covered his tits with his hands as Karyn burst in, pants still undone, with one hand inside her panties holding her crotch. Her face was red with shock and embarrassment.
"Jon, how could you?!?" she exclaimed. Jon started to laugh, and Karyn grabbed something out of her purse. She dropped it in her funnel before Jon could see what it was.
"What was that?" Jon asked.
"Let's see if you can figure it out," said Karyn. She turned her back to Jon and tried to do up her pants, but seemed to be struggling with something.
Jon's jaw dropped as he realized Karyn's problem. "Karyn, do you have an erection?"
"That's not a very polite question to ask a girl," Karyn said, smirking, "but yes, that seems to be the problem."
"May... may I see?" Jon asked hesitantly.
"I'll show you mine if you show me yours," Karyn said. Reluctantly, Jon let his hands drop, and allowed his big tits to bounce forward in their glory.
Karyn turned around and lowered her pants, showing a large boner sheathed in a latex condom jutting proudly from above the slit of her pussy.
"Here's mine, but I wasn't talking about your boobs," said Karyn.
Jon gasped, and he stood and pulled his pants and underwear down. His cock and balls were gone, replaced with a very cute, if somewhat hairy, vulva with a tampon string hanging out of it.
"Holy shit," Jon and Karyn said together.
