Ignis is pregnant with his and Gladio's first child, a son, Gladio's Amicitia heir. Ignis is naturally maternal and loves being pregnant, can't wait till he can mother his baby. Gladio just loves how happy and beautiful Ignis is while pregnant with his child. Cue Gladio being the ever doting dad to be. He makes sure Ignis is always comfortable, forces him to take it easy, pampers the hell out of his sore body...etc. Then Ignis goes into labor.

+Ignis gives birth with Gladio by his side. Even in labor, Ignis is quiet and proper. He makes little to no noise to Gladios shock.
++Gladio comforts his husband/lover during labor, feeding him ice chips, rubbing his stomach, whispering sweet encouragements...etc.

I just want domestic and sweet fluff. I'mma sucker for mpreg fluffy fics.
