"That's cool" the now conjoined twins said in unison "But we can't stay like this forever, right?"
As Luke said nothing, the twins moved their arms a bit, in search of a way to separate. This made Luke juggle a bit.
"I'll show you!" And as the kid said the words he went behind the merged boys's suit and pulled down a zipper. In a flinch the suit fell off, leaving two naked kids next one another.
"That's amazing!" Mark said.
"What should we try now?" Max said. "It was actually amazing what it felt like inside there."
"Really?" Luke was actually missing a bit trying the experience of merging with someone, but he didn't want to leave anyone unmerged were he to merge with one of the two brothers. "Guys, we have a problem. How can we all have fun? If two of us merge one is going to be left out, but I'd like to try the suit as well."
"Hmm." Mark said. "That is actually a problem."
"Ooh! I know what to do!" Max said to his brother and Luke. "Let's try to use the suit all three of us together!"
"What?" Mark and Luke said together, and Luke continued: "That cannot work. The suit is made for two people. Not three.".
And then Mark realized: "Even though it IS built for two people, no one told us we can't do that. Yes, it will be tight, but we can try, no one is stopping us."
And so it was: the three kids were going to wear the two-people suit together.
"How.... How do we address this?" One of the kids said, and they started talking.
"Well, for starters you should get rid of your clothes" The other said looking at Luke.
"Seems fair" the kid replied, and got immediately off all of his clothes. And as such the three kids were there, naked, near the suit tailored for only two.
"And now?"
"Let's start with what we have" Mark said. "Two of us go in, and the third joins in last."
"Agreed" the others said.
"I'll be the last" Luke said, raising his hand. "Come on, guys. Go in the suit."
"The two brothers went in the two-headed suit, with Max being on the right. The suit was already tight with only two people.
Luke went behind the not yet merged people, and inserted his right foot in the suit, on Max's side.
"Are we really doing this?"
"Hey, it's fine if you don't want to do it, but I bet it's so fun...."
"ALRIGHT. I'M DOING THIS. But wait, whose side should I join?"
Max then said:"What about both? Put your other leg in Mark's side."
"Clever" he replied "But there are only two head holes."
"We'll figure that out later. Let's get started." He slid his feet in both sides and lift up the zipper up all the way to the waist. He couldn't lift up the zipper anymore: it was too tight.
"I know what to do with the head holes!" Max then said. "Mark, help me out! We can stretch the head holes to intersect each other! Luke can fit in both maybe!"
"That's a genius idea!" Max and Luke said. "Let's do this." Luke fit in the bootleg hole made from the intersection of the two head holes, and tried again to pull up the zipper, in vain. "Guys, we need to be closer together, I can't close the zipper. I'll put my arms over your shoulders, and pull us together. You guys will have to pull the zipper though." "This will work!" The others said, while their naked bodies were being pulled closer together by Luke. All three kids were excited and getting harder because of this, and in the end they closed the zipper. They felt so tight and cozy with the body head the three were making together in the suit when it happened: they were pushed the closest possible to each other, and then somehow even more. Their bodies started melding together, the kids's shoulders merged and got closer, making their heads more close to each other. Their legs merged from six to two, with two legs for each teen except Luke's legs, of which there was one in each side. Even their crotches merged and the genitals merged in Luke's position, summing up their original sizes. Luke's arms, which were pulling closer Mark and Max, were merged into the backs of the two kids. And in the end, the suit tightened the most possible, and took the place of the skins of the teenagers.
