Let’s play a game

Emma and Charlie had no idea that the old game they found in the closet of their vacation rental was magical. They thought it was just some “adult” game and the bit about swapping body parts was all for fun.
“Okay,” Charlie said, reading one of the game cards. “Which of my body parts do you want to play for?”
“I don’t know,” she rolled her eyes.
“Come on, it’ll be fun.”
“Ok. Whatever. Your dick.”
Emma hadn’t wanted to come to this dump in the first place and now they were stuck in the house while a snowstorm raged outside. They rolled the dice. Emma won.
“Oh boy,” she said sullenly. “I won. Now what? I guess…”
She trailed off. Something was happening beneath her jeans. Things were moving. Something was…growing. Charlie’s face went white. He must be feeling something, too.
Emma’s pants were way too tight now. She zipped them down and screamed in surprise as a cock jumped out. It was warm and firm and connected to her. She could feel each inch of it.
After the initial panic, they decided they had to keep playing to get any chance to return to normal. But things just got more intense. Emma gained Charlie’s sex drive. His love of tits. His dominance.
She stopped the game before it got any worse and locked herself in the bedroom to try to figure things out. But her cock was calling to her. And her tits. She got naked and stared down at herself, stroking her new dick as it grew harder and harder, the desire building in her new balls until she came with a girlish groan, cum erupting down her fingers.
When it was over, she wanted to do it again. With Charlie next time. See how it felt to dominate his little pussy.
