The night before, Kevin, Allan and Dean forced their huge mass into Dean's car and set off to Max and Mark's house. Dean was driving but Allan kept fidgeting in anticipation, so their arms kept twitching around. They eventually reached the house and knocked on the door. No-one answered. They realised that the door was unlocked so they squeezed through the door frame. They ran upstairs and into Max and Mark's room and found the three boys sleeping, conjoined.
"Wake up!" whispered Kevin, gently nudging them.
"Wha..?" mumbled Max quietly as he woke up, followed by Mark:
"Huh..?"
"What're you three doing here?" asked Max, still not completely awake.
"We took off the suit and I was still stuck to them!" exclaimed Allan panicking.
"Shhh!" hissed Mark
"Look, will you just split us?" asked Dean hastily.
"Now?" asked Max.
"Yes!" shouted Allan.
"Will you please?" hissed Mark again, "Fine," he split from Zack (who was still asleep) but not Max and stood their body up. "How we gonna do this?"
"Well," started Max, "If you go between Dean and Allan, I'll go between Allan and Kevin and we'll just push apart."
"Sounds like a plan." said Mark, splitting from Max and walking backwards between Dean and Allan.
"Cool!" said Max, doing the same on the other side. They both merged into their place, making their five-headed body absolutely huge. Their arms looked like they could crush someone's head, they were at least seven or eight feet tall and Max couldn't help looking down at their cock, which was now about one and a half feet long and five inches wide!
"Look at that beast!" he exclaimed, yawning.
"Max... I don't think I have the energy to split us again..." said Mark, drowsily.
"Me-" he yawned, "either..."
"What?!" shouted Allan.
"We'll have to do it tommorow." commented Dean, smugly.
"But I sorta need to 'relax' to get to sleep..." admitted Allan, luckily no-one could look at him with the tight space on their shoulders.
"Same..." admitted Kevin.
"Well I for one could do with a bash on this monster!" said Mark, taking control of their tree-trunk of an arm and giving it a flick, causing it to heavily swing back and forth.
"It'd be a little wierd..." said Allan going red.
"So what?" asked Max, "I'm horny!"
"Fine." said Allan.
"Fine." they all agreed simultaneously, and Dean walked them over to the other bed so they didn't crush Zack. Eack one of their huge footsteps made a huge thump to match. They layed down on the bed and Kevin tried to pump.
"Dean, gimme a hand will ya? My hand won't reach around it!" said Kevin, amazed.
"Sure thing." replied Dean and they locked their fingers around it, causing them to both get horny. They pushed and pulled slowly as the cock was so thick and stiff. They Began to build up momentum and all five boys began moaning and grunting with pleasure. Their combined cock was getting harder, thicker and longer, growing to twice the size. Kevin and Dean's hand only stretched half way around it now. Max and Mark noticed this and just managed to pull two of their arms out of their chest to assist them. All four of their hands were now rubbing and squeezing their huge vainy cock. All five of them were now moaning loudly and carelessly when suddenly a huge thick spray of cum shot straight into Allans open moaning mouth. The fountain lasted for a solid ten seconds. They stopped rubbing their now red raw and throbbing dick which continued to occasionally squirt some jizz onto their six pack (which was now more of a fifteen pack). Allan spat the cum out onto their chest and the five boys passed out
