Slowly, the boys began to lift the shirt, which now seemed a lot baggier, up. They froze as the shirt was lifted half way up, stopping to stare. There was only one stomach; one belly button underneath the shirt. "Luke?" Mark questioned, unable to look away. "Where is your stomach?"
"Wh-what?" Luke stared at the strange sight. "That is my stomach. That has to be mine? Where is yours? We were right beside each other when we put the shirt on." Luke dropped the side of the shirt he was holding and it fell to partially cover the single stomach. He reached over, across the shirt to roughly pat and rub Mark's shoulder. "Where is my other arm? We wrapped them around each other... right? I can't feel it. I... I can't feel it."
"Stop that!" Mark smacked Luke's hand away, letting go of the shirt and letting it hide the single stomach again. "That's my arm." That statement sat in the air for a moment, both slowly took in the gravity of that statement. "This can't be happening." Mark finally said.
Max was simply staring at his brother and friend, unable to come up with any words. But he was starting to notice something strange. It surprised him that he hadn't noticed it before. Mark and Luke's faces. "Guys, your-your faces." Max pointed a finger. "They look different. I-I mean that they look different from... before." Max knew his brother's face. It was just about the same as his own face as him and Mark were twins, identical. Or, they at least used to be twins. As they were talking, both Mark and Luke's faces seemed to morph, right in front of him. Mark resembled Luke more than he did Max. "You guys look like... brothers." Not twins, at least not yet.
Mark and Luke shifted their attention to look at each other. "Holy Shift." Luke said as he stared.
"Yeah holy shit!" Mark repeated. "What is happening?" Mark began to work the extra large shirt up, trying to take it off. "Help me!" Mark commanded.
Luke hurriedly helped Mark completely take off the shirt, revealing what they were fearing. There was only one torso. Mark and Luke shifted to see themselves in the mirror. Their faces did not seem to be changing anymore; taking off the shirt might have stopped whatever was happening above their waist. But, they more closely resembled each other now, Mark looking more like Luke's brother than Max's. Their two necks met the same shoulders. There was just enough space between them so they could look almost face-to-face if they wanted to. But, neither wanted to at this point. Their gazes were fixed on their reflection. "The pants!" Luke said, suddenly remember the large pair of sweat pants that somehow were still around a waist they clearly shared. Mark and Luke uncoordinatedly tried to strip the pants off of themselves. Mark tried to lean forward to strip the pant leg off, which turned out to be a bad idea. The pair fell sideways having lost their balance. Rolling onto their back, they continued to pull and yank the pants off as quickly as possible.
Before they had started getting into the clothes for the challenge, the teens had decided to leave their shorts on as they would easily remain covered by the larger pants and it would help keep those larger pants on. They were now wearing one pair of shorts that was blended together from the two separate pairs they had been wearing. And as they had dreaded, there were only two legs and two feet, one for each of them. The fun game, the conjoined twin challenge, that they had agreed to try seemed a little more permanent. They had literally become a two-headed boy.
