You look at your body-bros and see your short necks that young dragons have. You feel four heads were how you were always meant to be. You also feel that 16 legs aren't too many to handle. Soon enough, you forget you life as a human altogether.
It seems like you and your brothers are becoming truly one. You start to feel their brains as your and they feel yours as theirs. You soon think you are 1 4-headed dragon instead of 4 1-headed dragons.
"My brethren... We must conjoin like our wives before us, so we can live a truly unified life. We will mate with our conjoined wives to form a new race of superdragons." Your father said. Your soon-to-be fathers all walked towards one another and where they met they fused into a single being. Your fathers had long necks, developed wings and mature bodies that came with adulthood.
"Come my mate. We must give birth to the next generation." Your mothers said in unison, their minds finally melding.
You wish that you were an adult like they were. Suddenly, your body starts to grow as do your necks. Your wings grow out and you now have 4 pairs of them. You now resemble your parents in almost every way.
What happens next?
