They looked in a mirror and were amazed at the sight. Mark was on the left, with Luke to his right.
“Awesome!” Luke shouted, “This is so cool!”
“Wow, I can’t believe that actually worked, we’re conjoined in one body.” Mark was staring into the mirror in disbelieve at the image of the two-headed guy looking back at them.
“Yah I know! So this is what it’s like being stuck together with someone. I can feel everything you feel!” Luke said as he used their left hand to feel around the side that Mark was on. “Haha, that tickles. This is so weird!”
“Hey stop that. I don’t like being tickled.” Mark exclaimed as he smiled holding back laughter. He then tried to move their left hand away from their side, but it started jerking around randomly as Luke was still trying to use it. “Looks like we both share movement, so we can’t use the same limbs at the same time. Otherwise they just jerk around.”
“You mean like this!” Luke proceeded to move the left arm back towards Mark and started tickling him again. “Hehehe, there’s no use trying to fight it! We’re stuck together forever! You can’t get away from me!”
“Hahaha! No… fair… I c…c…can’t stop… you!” Mark would have been rolling on the floor at this point had he not been joined to his friend. “Let’s see… how you… like it!” Mark then took control of the arm on Luke’s side and began tickling him as well. The two of them were laughing so hard that tears began rolling down their cheeks. Soon Mark and Luke fell to the ground after trying to keep balance on only one set of legs.
“Time out, time out! I give!” Mark chuckled wiping away the tears from his face. He was still smiling when he looked down towards their legs, and was shocked at what he saw. During their tickle war, Mark and Luke had given themselves a boner and hadn’t even notice! “Umm Luke? I think you should see this.”
“What is it?” Luke said still fighting the last of his giggles away. He followed Mark’s gaze and looked down. It took Luke a minute to realize that their shared cock was now hard and throbbing with excitement. “Huh, well that’s odd.” He stated as he used their right hand to grip it and begin pumping it up and down. “There’s no point in letting it go to waste. Right?”
“I guess, but doesn’t it seem wrong? I mean, your jacking me off.” Mark’s words were fast and spaced apart as he was starting to take deeper and longer breaths.
“Eh, not really. This is still your hand and your dick. It just so happens that they are also mine. Just imagine it’s you and I’m not here.” Luke barely finished his sentence.
“I guess your right” Mark moaned as Luke began pumping faster and faster…
