After finishing lunch with Kevin-Dean-Allan at Scott's house, Mark-Max-Zack-Luke decided to go back to Luke's own house to check on his dad and theirs. Their five feet shuffled them out the door and across the lawn, then across the street to Luke's house. They walked inside, but could not see Ethan or Scott. Then Mark noticed light coming from the door to the basement, but when they tried the door it was locked. Fortunately, Luke knew where to find the key to the door, and after the four body bros got it they opened the door and walked down the stairs.
In the basement, they saw Ethan and Scott's fused clothes lying on the floor and couch, including a trio of boxers. Then Max noticed the fogged-up door to the steam room--it didn't take long for the teens to figure out that their dads were in there.
As Ethan-Scott relaxed from their conjoined self-pleasure, they heard a knock on the door. They were nervous at first, worried that it might be someone who didn't know about their fusion abilities. But when they saw the silhouette of the figure behind the door, they became much more at ease when they could tell that the figure had four heads.
"Just a sec!" Ethan called as he and Scott draped one of the towels over their packages and middle leg.
"Come in!" Scott called.
The four teens opened the door and greeted the conjoined men.
"Hey, Ethan," said Mark.
"Hiya, dad," said Max.
"How's it going?" asked Zack.
"Pretty good, son," Scott replied to Zack.
"Mind if we sit in here for a while?" Luke asked.
"Go ahead," Ethan replied.
The teens shut the door for a second to strip. The first thing to go was the Hawaiian hoodie, then the shirt, then the sweatpants, then the socks. This left the quin of underwear, the fused boxers and briefs, which the quad were able to remove without much difficulty. Piling their clothes next to the door, they took a couple towels and wrapped them around their shared waist to cover their four cocks. They went back into the steam room, shut the door, and sat down on one of the benches near Ethan and Scott.
"Hey, dad," Luke asked Ethan, "what time does Evan's flight get to the airport?"
"Probably...about half an hour from now," Ethan realized, "which means I better get going to pick him up."
"Does that mean our time together has to be put on hold for a while?" Scott asked.
"Guess so," Ethan replied. "We agreed we have to this a secret from Evan for the time being."
Ethan and Scott turned their heads to Mark-Max-Zack-Luke.
"And boys, while I pick up Evan, you four and Scott have to stay and undo all of this fusion, including our clothes," Ethan told them. "We can't take any chances yet."
"Why should we?" Mark asked. "I get that we can't let Evan know yet, but I don't know if we wanna spend too much time without being fused to someone. Besides, maybe we could just keep the fused clothes as they are for now. We could wear them to simulate our conjoined bodies and pass them off to Evan as costumes."
"Mark," Ethan replied, "I am fused with Scott. That means I'm your dad now, and Max's, and Zack's. That means all four of you have to do what the two of us say. And we say to hide all of it. End of discussion."
With that, the two-headed dad(s) stood up and walked out of the room, their towel still wrapped around their waist. In the other room, they slipped their clothes back on--the boxers, the pants, the shirt, and the jacket. Once they were dressed, Ethan and Scott unfused from each other, turning back into two one-headed forty-year-olds. Their clothes unfused as well: Ethan was once again wearing a white shirt under a Hawaiian shirt with gray sweatpants, and Scott was once again wearing a red shirt under a black jacket with jeans. Before they went to the stairs to leave the basement, the dads looked back at their conjoined sons in the open steam room.
"You guys can have ten minutes in there," Scott told them, "then start unfusing everything."
"And that includes you," Ethan added. "I don't want to see you four fused together when I get home with Evan."
With that, the two dads walked up the stairs. Ethan got his keys and shoes and went out to his car, then drove off to the airport to pick up Luke's fifteen-year-old cousin. Meanwhile, Scott went back across the street to his own house--since he had fusion powers as well, he thought he'd do a little cleaning in his own house, to separate any clothes left there that might be fused together.
