Because I've never done an overnight.  First of all, I look scary as shit in the morning and would not inflict that, along with diesel breath, on any woman.  Second, I won't pay anyone to sleep next to me. Third, I don't like "wake-up sex."
Funny story though.

When seeing the provider sans make-up and couture, with tangled hair….

and a trace of drool at the corner of her mouth it was me who "yelled"

Morning sex is the best to wake up to...

unless you're in prison.

Was she a bit zonked out the night before?

Sounds more like the kind of question you get from a civie you hook up with when they call final round at a bar.

I had an exceptionally long Sunday that started with a buddy and me splitting four bottles of Champagne for lunch, continued with four more bottles during the late afternoon NFL games, then graduated to tequila during the evening, how many I don't have even a clue, nor do I really remember much of the evening.

Fast forward to the morning. My eyes didn't even open until somewhere around 10 AM, the first thing I had to do was figure out which country I was in as all hotel rooms start looking alike after a while, as I was getting my bearings and remembering that yes, I was in Panama, in my own room and that all appeared to be ok, I realized that I wasn't alone in bed. I was almost scared to pull back the covers, wondering just what I had dragged home that night, but I sucked it up, pulled back the covers, and much to my surprise and delight, discovered this gorgeous little Colombiana hottie.

Yes, some mornings are better than others. lol

BTW, I did NOT yell "who the fuck are you?" come to think of it, I never even asked her name until well after our wake up sex, and just before I asked her to spend another day with me, a slightly more sober day of course.

Joke. I don't look good in the morning, so I usually have to sneak out of bed and go primp before he gets up and wants a bj.

Forgetting where the hell I am. Luckily, I remember before I scream.

I've only done a couple overnights, with the same client, though, and as terrifying as I may look with no eyebrows (genetics gave me wimpy little brows that are hardly long/thick enough to be expressive), the only screaming involved was in the shower that morning...

I talk in my sleep, squirm around, and now I guess punch 'em in the stomach with my head.

So, no. No long engagements for me over 4 hours anymore, lol.
