After finishing their conjoined arm wrestling, Luke and Ethan walked into their kitchen to get some breakfast. It was easy for them to walk as one since they had three legs and were able to coordinate easily. Breakfast was simple: toast and jam with coffee for Ethan, pancakes and hash browns for Luke. They did not need to have much else to be satisfied, since they only had the one stomach between them. After breakfast came something else, something that the pair had done before: they were going to take another shower together.
Their legs moved in unison up the stairs: their two unshared legs, then the shared middle leg, and repeat. At the top, they moved towards Ethan's bedroom and dumped their clothes in the hamper. They entered the master bathroom, but did not close the door--they had the house to themselves, after all. They noticed that they were still wearing their shared underwear, which they had put back on before fusing for their arm wrestling. It was now an unusual "trio" of underwear, and not just because the three legs: Ethan's side was briefs, while Luke's was boxers. It would be unusual to own such underwear, but the two decided to just take them off and worry about unfusing them later--maybe they could try putting them on again when they still had three legs and try unfusing back to normal.
Regardless, they each grabbed their own side of the underwear and pulled it down to their ankles. As they pulled their feet out, they noticed that they each had their own packages--one less thing to worry about in the shower.
"You've still got a nice package, dad," Luke smiled at Ethan.
"Runs in the family, son," Ethan smiled as he gestured towards Luke's. Normally, the pair would have been grossed out with any conversation concerning their endowments; with all this fusing, their father-son relationship was now more of a relationship between two frat boys or two homosexuals, both of the same age. There was no awkwardness this morning.
Ethan turned the handle and started the water, and the pair stepped inside, leaving the shower curtain open. They each took their own brush and washcloth in with them, since they were going to scrub their respective half of the body. It was an incredible feeling: two men scrubbing their shared body as though they had been joined all their lives, as though they were born this way and the same age.
After five minutes of warm suds, during which there were a few minutes of pleasure and stiffness, Ethan and Luke stepped out of the shower and started drying themselves off. Once they finished, they picked up their shared underwear, tossed it in Ethan's hamper, and opened his closet to find some clothes to wear. They unfused their shared leg for a moment to properly put on their own pairs of underwear and jeans, and then fused back into three legs, included their clothes. They now wore a large white shirt with one neck hole, a blue-green unbuttoned Hawaiian shirt over it, a trio of boxers, a trio of black socks, and gray sweatpants that now had three legs.
