I've finally written it :) Enjoy!
"Hello, little guy", Hisagi whispered to the small pink creature resting on Kira's chest. "Say hi to the happiest daddy in the world!"
"Hi", it was Kira who whispered back harshly. His face was still pale, gleaming with tears, and he had puffy eyes. But his smile was peaceful.
They looked each other in the eyes for a long while.
"It's a boy", Kira finally broke the silence. "We're gonna go fishing together when he grows up, right? And sparring together. And drinking sake together. We're gonna do all those fun things, right?"
"Shh", Hisagi shushed him. Kira's eyes filled with tears once again.
"Sorry, I'm just still a bit... scared", Kira whispered in a very low voice, stroking the baby boy's little hairless head.
"It's only natural", they jumped at Unohana interrupting them. None of them was aware she was still in the room. "But everything will be fine, with such wonderful parents. Besides, everyone here will help you, so stop stressing, my dear Izuru. You and the baby deserve rest right now."
Hisagi lifted his gaze to see Renji waving at them through the glass pane in the door. He laughed at him. The baby stirred on Kira's chest, emitting a squeaking sound.
"He's so cute", Kira chuckled.
"I never thought it would be so...", Hisagi muttered, watching Kira's ministrations with much attention. The baby boy was trying to look at daddy around his own head.
"So what?"
"So sexy."
Kira scolded him with his gaze, but smiled and blushed anyway. The baby finally caught Kira's swollen nipple in his mouth and sucked eagerly.
"It hurts like hell for sure", Kira sighed. "But it's kind of... worth it, actually."
Hisagi laughed and placed little kisses on Kira's and the baby's heads.
"How are we going to name him?", he asked. Kira smiled softly, adjusting his hold on the little creature.
"Can we think about it tomorrow? We have plenty of time..."
