Timing Isn't Always The Best

                                    

                                          
The first few hours of labor, you were the calmest amongst everyone there. With Bulma already having a designated spot for this 'at home delivery', you were really just enjoying a cup of crushed ice. Zamasu was being calm for your sake, but apparently the birth of twin 'gods and/or goddesses', was something to not take lightly. At all. 
Why?
The apparent amount of hypothetical destruction that was to probably happen. Considering your strength from just the contractions alone, actual labor may mean the end of the world. Even Beerus was overly nervous.
The second your labor pains actually kick in, is when you realize that you(or rather the others) might be in for a long night of trying not to accidentally kill everyone. Whis promised to use the temporal rewind power that he had in case it did indeed get that bad, but only if it was really needed.
It might be needed, though.
After a full ten hours, and only minimal damage done to the surrounding room (no actual damage to the people allowed in the room during this either), the house was almost quiet. 
There was actually plenty of buzzing and bubbling excitement, outside of the designated delivery room, but Bulma had to tell the group that you and Zamasu needed this time to get personally bonded with your newborn children.
Zamasu was overwhelmed as he looked at his newborn twins, a boy and a girl. He couldn't believe he was now a father, no matter how prepared that he thought he was. As they rested against your upper chest, while you held them carefully, you couldn't help but to chuckle softly. 
Both children were a beautiful shade of green like their father, but both had full heads of dark hair. Their ears weren't as pointed either, being slightly curled at the tips.
The emotions he felt were indescribable, but the happiness he experienced was the most prominent. He delicately touched their tiny hands, afraid of causing them any harm.
However, your tired smile reassured him that they were not as fragile as he thought. "They need to hear your voice too, Zamasu," you said, your voice filled with love and exhaustion.
"Hello, (B/N), (G/N).. it's wonderful to finally meet you," Zamasu whispered, still cautious of their delicate ears.
As the newborn children stirred from hearing their father speaking to them, their innocent and large doe eyes met those of their father's sharper eyes. It was both strange and beautifully divine to see the colors of their irises. Heterochromia, what they called it. (B/N)'s right eye was grey, and his left your eye color. And it was the same for (G/N)'s, but in the opposite order.
Zamasu felt a huge rush of pride swell up in his heart, as the strong sense of love and protection went through him like the largest bolt of energy. The connection between father and children was undeniable, as their eyes locked in a moment of pure connection and understanding. It was a beautiful sight to behold, filled with immense joy and optimism for the future.
Tears prickled at the corners of Zamasu's eyes, before he looked up at you, resting his hand over your free one gently. 
"This feels like a dream..." He whispered softly, the kai's voice breaking openly as you gently entwined your fingers with his. You nod softly, feeling your own tears welling up as you smile at him.
Zamasu gently rests his forehead against yours for a moment before he gently presses light kisses to each of the children's temples, an undeniable look of happiness on his face.
*****
After a good month of staying on earth and letting everyone get acquainted with the newborns (and with you recovering, and Zamasu getting used to his new role of father to make sure everything was done correctly in caring for the twins), your new family returned back to Universe 10.
