Games had always been a core part of Mark’s life. He enjoyed all kinds of games and was often the first to suggest one when hanging out with friends. Over time, the love of games progressed into an outright obsession. It didn't matter if it was sports, board games, card games, or video games; Mark was interested and wanted to participate. This obsession began to push away friends and family who wanted to just hang out and relax instead of constantly learning about or playing some game when Mark was around. The further he followed his obsession, the more alone he became. 

One day, while walking home and playing with a Tamagotchi, a man stepped out from an alleyway before him. 

“Would you like to play a little game?” he asked with a smile.

“Yeah, sure!” Mark replied without even hesitating.

“Excellent, right this way,” said the man, beckoning him into a side door in the alley. The room that Mark was led into appeared to be a studio apartment with various pieces of furniture placed haphazardly about the place. “The rules are simple,” said the man. “You’ll be playing the floor is lava. You must move once every 10 seconds, or you lose. You also lose if you touch the floor. Be careful though; there are consequences for losing.”

“What kind of consequences?” asked Mark.

“Oh, I’m sure you’ll find out,” replied the man with a wink.

Mark got set up on top of a sofa, and the man began a complex timer on the wall. It had an overall countdown for the length of the game as well as a ten-second timer that reset with each piece of furniture Mark was able to move onto. Mark began to move from object to object, but almost immediately he stepped on a table that was more wobbly than it looked and fell to the floor. The man stopped the timer as Mark stood up. As he grabbed the edge of the table for support, he noticed that his fingernails were now somehow painted bright red. Was that the punishment for losing?

“Again!” said the man forcefully.

Mark, wanting to prove he was better than the performance he had just displayed, got back into position, and the timer was started again. Mark began again, making it to 15 consecutive moves before a pillow he landed on slid out from underneath him and left him lying on his back. He had to brush his now long red hair out of his eyes in order to see to get back up, which also revealed a pair of A-cup breasts that had formed on his chest. Mark was starting to get the picture of what was going on here. Every time he fell, he was being progressively turned into a woman. This just made Mark more determined to win.

He got set up and going, making it all the way to move 33 before mistepping and landing one foot fully on the floor. The second his heel touched the carpet, his pants disappeared off of his body, and his cock winked out of existence. The game continued for three more rounds; each time, Mark would get further but ultimately make a mistake, resulting in further changes. After the last round, Mark found that she was now sporting rather large tits compared to the ones she had started out with, and her ass had done some growing as well. She got onto a chair, positioning herself to start another round, but when she looked up, the man was gone. The door to leave hadn’t opened, and there was nowhere to hide in the small room. The man had simply vanished, leaving Mark behind in a new body with no clothes. Maybe she would just play a few rounds by herself, she thought. A little practice couldn't hurt.
