Your parents' elongated, serpentine bodies wrapped around each other, each of their 16 legs wrapped around the other. They squeezed as your fathers' genetic material was transplanted into your mothers.
While they squeezed, their long bodies were fusing into one giving them a conjoined body. Eventually, they had 8 heads and 32 legs.
"We-I-uh... I am a god among dragons." All your parents voices said in unison, their minds were now fused as one. They were indistinguishable from each other and started to lay their eggs.
They layed 4 eggs and within ten seconds, they all hatched revealing 4 headed dragons. They instantly grew to mature age. They see their parents (or rather parent) and wish to be more like them. You tell them to conjoin with you to form the Master Dragon.
They walked towards you and fused with you. Your body elongated to accomodate the extra 48 legs. The base of your necks was somewhat crowded. You now had 16 pairs of wings, 64 legs, and 16 heads.
"I am the Master Dragon!" All of your heads roared in unison.
"Join with me if you wish. If not, you will be my mate. Take your pick." You bellow out, strongly.
"I will join you, my lord." Their inferior 8 heads said as one. They walked into you and their mind became yours. You now had 24 sets of wings, 24 heads and 80 legs. You decide that each head should regain its individuality.
"We are the Master Dragon!" All of your heads roared together, though their minds unified no longer.
"Lets bring all dragons to our cause. Unity is the only way." Several, but not all, of your heads said.
What happens next?
