Apparently this appears 15 times in my current (unpublished) WIP, and I’m actually surprised it’s that low a figure lol. But here’s a couple of instances:

If he lost Rob, there’d be fuck all else to stay alive for. 

“Fuck,” he mutters eventually. “We’re going to have to go.”

“Let’s just… fuck off, y’know? Just you and me.”

Also, seeing as we mentioned it the other day, here’s a couple from the currently dormant sex worker AU (which, perhaps surprisingly, has roughly the same number of usages of the word ‘fuck’ and is only a little bit shorter):

Felipe looks him up and down, and to be fair to him the way he grins, the way he’s almost leering, looks like any other guy Rob might’ve picked up in a bar, horny and eager and wanting to fuck. 

Or he can own up, tell Jenson he caved to an attractive young guy and paid a lot of money to fuck him.
