Kids Are Tiring... (Sasuke X Naruto)
First Book: I'm In Heat! (Sasuke X Naruto)
Second Book: You are here!
One kid is hard. Two kids is harder. Two kids who happened to be twins is harder. And very tiring. Waking up in the middle of the night to their crying, feeding them, changing their diapers. Even without training, me and Sasuke are worn out by the end of the day.
But, I wouldn't change it for the world.
