Hinata is dreaming about becoming Naruto’s wife, and as a wife you obviously have some duties. Be it cleaning the house, making dinner, or even having sex with your husband. Especially as a new couple you can’t wait to fuck. Well it’s not much different with this amorous couple. Also I wanted to add an important sentence that you might want to remember for RL.
“But while I’m pregnant, you’ll have to use the back door!”
