"I wish all the women in here had really big boobs."
Suddenly, the stone in his hand flashed, and he had to squinch his eyes shut for a second. When he opened them again, the Asian woman had changed. She was still in the same position and the same skirt, but now she had globes the size of honeydew melons on her chest, still with the brown nipples that he was enjoying. He flipped back to the brunette in the bustier, which now strained against her much bigger tits. Even the blonde who he'd seen first seemed to have a bit more up top. He looked at the rock in his hand and whispered, "Whoa, this thing really does grant wishes!"
He turned to the Asian woman once again. He felt his dick straining against his underwear inside his jeans, and it felt like some pre-cum was leaking out. He thought for half a second about the wording of his next wish: "I wish she was here in this room."
