“Hi, nice to see you. Would you like a drink (or would you like water?). Have a seat.“
Pour water into the glass- take a minute. Carry it over.
“Ah. Refreshing. So, how was your day? You’re a... (job)? That‘s so interesting, I’ve always wondered (any damned thing you can think of related to that job. Even something stupid and wrong because they’ll think it‘s cute and still get to explain something. Men love that.). Other solid options are “Are you originally from here?” or “What’s the last great trip you took?”
While he’s talking, tell him “Please, go on, but why don’t I rub your shoulders/give you a little massage while we chat.”
Talk until there’s a significant lull. Then either invite him to shower or to get comfortable.
Then do whatever you already do.
Afterwards, don’t ask, just straight up tell him to lay down so you can rub his back. Make a positive comment about his body (even the most sloppy obese person probably has great calves. Or looks like they used to play football. Whatever- just positive and true.)
Ask if he’d like to shower before leaving. Get yourself dressed regardless so he knows it’s time to go.
And THAT is how you provide a lovely hour even if the guy has zero stamina.
Done.
