Luke and Max were still making out, forgetting that they were also conjoined with their fathers. At first, Ethan and Scott tried to distance themselves, not sure what to think, do, or say. But they could both feel what their sons were feeling for each other thanks to all four of them being connected by one big chest. Ethan couldn't help it, his hand slipped down into his and Luke's pants, putting his fingers around their cock once again.
Luke's head jerked back as he felt his hand around his cock and start rubbing it by itself. He instantly remembered his dad and wiped his head around staring right in Ethan's face. Ethan had a silly grin on his face and continued to beat away.
Max too had realized that Scott's head was just to the right of his. Max glanced over, worried and afraid, but he saw his dad holding back from laughing. When Max and Luke looked back at each other, they turned equal shades of red, making their chest burn on the inside. Ethan could feel his and Luke's cock going limp, "Oh come on. You guys are stopping?"
"Looks like it." Scott sighed, "Guess they're embarrassed now."
"Ug, that sucks..." Ethan pulled his hand up and sighed, "I was just getting into it too..."
"Ya!" Scott exclaimed, looking over to his left at Max and Luke, "This might sounds weird, but I was enjoying that feeling you guys were sharing."
"Really?" Max sheepishly asked.
"Yah!" Ethan and Scott cheered. Ethan leaned his head against Luke's, "Why don't you guys keep going, me and Scott don't mind. We might even help!"
Luke and Max stared intently at each other, as though they were reading each others thoughts, before turning in unison to their own dad, "Ok..." Luke and Max once again started off slow and easy, while Ethan and Scott managed their legs and got them to the bed. Scott and Max lay on top of Ethan and Luke as the two of them really started going at it. The two shared cocks were rock hard and throbbing against each other, Ethan and Scott took hold of the one they were sharing with their own son, rubbing fast and hard.
Luke and Max had stopped kissing, and now had their faces rubbing together as Max and Scott arched their back, pulling Luke and Ethan off the bed slightly. Their breathing was heavy as their hearts raced to keep up with their huge sweet soaked chest. It wasn't long before each pair shot a load of cum out of the cock they were sharing, straight into the bottom of where all four of them merged.
Ethan and Luke stretched out their body, as did Scott and Max, each pair trying to cool off. Max was resting his head on Luke's as both of them watched their fathers. Scott and Ethan were staring at each other with giant grins, feeling the pleasure wash over each and everyone of them. They glanced over at Max and Luke, and then all four of them started to laugh.
"That was amazing!" Max shouted, "I've been dying to do that all day with ya Luke."
"Ya! Me too!" Luke agreed.
"Ya, that was pretty good!" Scott shifted around getting more comfortable.
"Mmhmm. We should definitely do that again some time!" Ethan suggested, and Scott agreed. Max and Luke looked at each other, than back to their second heads, nodding in agreement. The four of them continued to lay there, enjoying each others company, and the feel of being so close.
