You were pregnant. It wasn't too surprising that you, a male, got pregnant after your and Itto's 'season', as you were an Omega and he an Alpha, but Itto was still caught off guard by it. It almost changed him...
—You're halfway through, and Itto has been calmer since everything started. He wasn't too rough or touchy with you anymore, would let you rest without having the urge to wake you up for his own sake, and would just randomly make you food and such; pretty much a gentleman. He wouldn't even let you do the big things anymore, not even pick up heavy stuff—he would just do it with no complain nor argument. However, Itto has been more clingly and protective aswell.
It was Saturday, and Itto took it for some extra sleep with you, as he liked you getting enough energy for the usual upcoming day. He was already awake tho, watching you murmur in your dreams. Itto smiled, his muscles flexing as he propped up on his elbow behind you, his cheek leaning into his palm.
