"Oh my god. What have we done?" Melanie said to her new body partner. "We've made everyone into boy-girl pairs of circus freaks. I didn't mean for this to happen." She said, throwing all four arms onto her face in a fit of tears.
"It's okay, Melanie. Now, everyone can have a relationship like ours. Always together forever and ever." Jon said, romantically but Melanie still didn't like any of this.
"But how can you be so calm in all of this?" Melanie asked him. "I forced you to fuse together with me against your will." Jon took his two hands and held Melanie's pair.
"Babe, I love you. Fusing together with you was simply the next step, or at least it would have been had that even been a possibility." Jon said to her, comfortingly. "I remember hearing an old Greek story about how humans were originally made with two heads, four arms, four legs and both sex characteristics. Zeus didn't like that the humans were so happy so he split them in two. Maybe this is me finding my other half in you. And now, everyone is with their other half." Jon said. What Jon said was true. After the people of the world had gotten over the fact that they were now sharing a body with one other person, they loved their other half immensely.
Melanie and Jon wished that the people could welcome more people into their body at will and entire families were born and fused to each other. Melanie and Jon even had children who would fuse with them and their children would separate and fuse together and everyone was happy.
But what happens after so long, living in the world of fusion and multiple bodied people...
