How to respond?

My boyfriend and I have been together a little over 7 months and don’t get me wrong, we have sex alllll the time, but neither of us are into dirty talk or anything but I’m at work right now and he texted me

“You should hurry home so I can fuck your brains out”

And I don’t know how to respond!!! I have 3 hours left on my shift. I’m kinda new to relationships and sex, he’s the only person I’ve been with romantically and physically.
