"You're not so shabby yourself." John's reflection winked back.
John stumbled back from the mirror, his reflection no longer copying his movements. "What the fuck?"
The 'Mirror John' just stood there and laughed.
"Hey, relax. A minute ago it looked like you were ready to start making out with me." Mirror John chuckled.
"Well, erm..." John blushed.
"Like I said, relax. I'm you, remember?" His reflection smiled comfortingly.
"Yeah. I suppose you are," John nodded "Hey, how can you talk?"
"Haven't you every watched a cartoon before? This shit happens all the time." Mirror John smirked.
"Heh, guess I forgot. Still gettin’ used to the whole ToonWorld thing. Hey, can you come over, like out of the mirror?" He asked.
"Only if you invite me." Mirror John replied, looking slightly hopeful.
"Well, consider yourself invited." John's reflection smiled, and walked towards the mirror. As he placed his hand on the glass, it began to ripple like water. Slowly he pushed his hand through, which was followed by his large gut. John's bloated image was almost through when he stopped suddenly, stuck in the frame. John burst out laughing.
"Hey," his mirror image looked slightly annoyed "stop yukking it up over there and give me a hand." John moved over to the mirror and began to pull john's arm.
"Man you're really stuck there aren't you?"
"Just keep on trying." With one mighty pull, John freed his reflection, who managed to use John to cushion the fall.
"Jesus, your heavy." John said as Mirror-John rolled off of him.
"Yeah, well I seem to remember you doing this." Mirror-John said as he slapped his huge gut.
"I suppose you right. Sorry about that." John looked slightly sheepish as he apologised.
"No biggie. 'Cept for me that is." The mirror image joked and rose, helping John to his feet also.
"Hey, since I pulled you, now you can do the same for me. Pull my finger." Laughing, Mirror-John complied and pulled the offered digit. John made a long and echoing fart, causing them both to laugh again. The laughing stopped however when loud grumbles came from both Johns.
"Man, I feel bloated." Said Mirror-John. A slight hissing sound could be heard, and John looked around for what it could be. Turning to his reflection, he saw it was coming form him! John looked at his larger double and the two watched as he inflated. Slowly, his already bloated gut grew bigger and bigger. His ass becoming more bulbous and his thighs and arms more chunky. It stopped after a few seconds but the change was very noticeable. Mirror John looked like a small human parade balloon! His rounded form preventing his arms from resting flush against his sides, he looked like he'd been blown up with a mixture of gas and lard.
John walked over to the fat-ass in front of him. He pressed into his gut and found that while it looked firm, felt like fat.
"Hey, knock it off." His mirror image tried to swat him with his hand but failed miserably.
"So when I have gas, you blow up?" John asked as he circled like a vulture.
"Looks like it." Mirror John said as he turned to face him.
"Heh, looks like we can have a bit of fun, eh porky?" John said as he slapped Mirror-John's gut, the action causing the reflection to burp. As John continued to inspect his double, he didn't notice the changes happening to him. Slowly his belly lost its definition and rose to form a small dome of fatty gut. It wasn't overly obvious, but enough for Mirror-John to see.
'Well, it looks like this goes both ways. Maybe I should stick around for a while.' Mirror-John thought to himself.
