After a while, the two-headed family members began to feel a little bored. They had each fused with most of the guys in the room at least once, and they began to wonder if there was any way to shake things up anymore. When the door opened, they realized that they could still shake--or rather merge-- things up.
A whole range of the boys' friends walked in: Kevin, Dean, Allan, Brian, and Nick. Each had been a conjoined twin with one or two of the others, and all were beginning to miss having more than one head and sharing a body with someone. This was perfect, and it did not take long for all eleven heads to begin planning how each person would be conjoined and to whom.
There were some bumps in the planning. Luke was surprised that Max wanted to separate from him, but realized that it might be better if Max was conjoined with his own brothers. Kevin and Dean hoped to be conjoined again, and this time wanted to bring Allan into their form, seeing as how Allan was relatively new to the conjoining business. Allan was a bit upset about Max accidentally fusing with him earlier, but had forgiven him, and wanted to get closer with his own friends. Brian and Nick were Max's friends, but they were also Luke's; with Max wanting some time with his true brothers, Nick and Brian agreed to join with Luke. Ethan and Scott, being the dads of the group, decided that they would be perfectly happy staying the two-headed man they were. As for Mark and Zack, they looked forward to staying body bros, as well as welcoming Max--seeing as how he was Mark's identical twin before all of this began.
Next came the truly complicated business: the conjoining itself. Luke and Max both pulled away from each other, infusing themselves in the process. The two then used their fusing powers to work with the others. Luke pushed Kevin into Allan's right side, and Max pushed Dean into Allan's left side. Using their powers, Luke and Max successfully fused Kevin, Allan, and Dean. Their body was pretty much normal from the shoulders down--two arms, two legs, one torso--except that the torso, waist and shoulders were fifty-four inches across. On the shoulders, all three heads were spaced evenly apart, with Kevin's on their right-hand side, Dean's on their left, and Allan's in the middle. Fortunately, their clothes had all merged perfectly--one large pair of jeans, an oversized pair of shoes, and a large green shirt with three head holes.
Next, Luke and Max were to fuse with the others. Luke stood between Brian and Nick, and told both of them to push their sides against his own. Just like with Kevin-Allan-Dean, they merged into a two-armed, two-legged, three-headed body--Brian's head on their right-hand side, Nick's on the left, and Luke's between theirs. Their clothes matched their friends' as well, except their newly merged shirt was red.
All that remained was Max and his brothers. Since Mark and Zack were already joined, Max simply backed up into them. Their body was exactly like their friends' new bodies--Mark's head was on the left-hand side, Zack's on the right, Max's in between. Their clothes matched as well, except for Mark-Max-Zack's blue shirt.
Every head was amazed at what he saw: a two-headed man and three three-headed boys. Every group of body bros was perfectly coordinated with two arms and two legs, and began to feel perfectly content as a conjoined sibling. None of them wanted to change back--at least, not until they had to leave or until they got sick of it.
The only thing awkward was the family relationships: as conjoined fathers, Ethan and Scott could understand raising Mark,Max,Zack and Luke, but felt a little confused as to whether of not they were now Brian and Nick's dads. And what about Kevin, Allan, and Dean? None of them were related to the dads, so how would that work?
After a while, they decided to brush off the family tree question and enjoy themselves.
