Option #5 (Just Add Anon)

When Night Light heard a grunt from the pillow beside his own, he woke up with a start.

A flat green face met Night Light's eyes. But thank Celestia, at least its own eyes were closed.

No, Night Light thought. This can't be happening. There's no possible way--

The green creature's eyes opened. "Hello, sunshine! What a beautiful morning!"

Night Light looked around the room. He saw dark suit trousers, draped over a lampshade. A matching jacket lay across the floor. A tie and white dress shirt festooned a chair and a light fixture.

"No," Night Light said. "I can't believe it."

"Believe it, babe!" The green creature sat up, the sheet sliding down off its chest.

Night Light stared. On the creature's chest, a pair of pasties supported one tassel each. The creature flexed its chest muscles. "Admiring my little decorations? You sure seemed fascinated by them last night." It grinned.

"How could I possibly have done...what it seems I did?"

The creature gently patted Night Light through the sheets. "Ever since I started Human Stripper Service, a LOT of ponies have been doing what you did."

Night Light grimaced. Then he had a thought. "Names."

"What?"

"Names. Who are these ponies?"

"Why? Do you want to find other ponies as freaky as you are?"

"I just...want to know." He remembered something the creature had said, yesterday evening, before Night Light offered to pay it fifty bits, before Night Light humiliated and degraded himself. "Did Twilight Velvet really hire you to strip for her? Did you really sleep with her? Did she really say you were the best in bed of anypony she'd ever had?"

The creature put a hand on its chin. "Twilight Velvet...Twilight Velvet. No."

"What? What do you mean, no?"

"No. They say in my home world, 'fake it to make it.' So I faked it. I told you an Equestrian Princess had paid me to strip for her, and paid me to have sex with her. I thought if I said that, ponies would hire me. And it worked, didn't it?" The creature smiled proudly. "See? Humans are clever. You ponies could learn a lot from us."

Night Light replied, "You utter dingus. You nincompoop. Last night, you said you'd worked for Twilight VELVET. If you'd meant to say you'd been hired by a PRINCESS, you got her name wrong. Twilight SPARKLE is a princess. Twilight VELVET is my WIFE."

"Oh. I said I'd had sex with your wife? Sorry about that. I didn't mean to make you mad."

Night Light sighed. His horn lit up, and a soft glow of magic wreathed the room's window latch. The window opened. "I have an idea," Night Light said. "This hotel room has a great view. You want to see it? No point in wasting any of the room's amenties."

The creature tossed its covering bedsheets aside. Night Light looked at what had been exposed, and shook his head. He thought, I can't believe I slept with THAT. How drunk did I have to get myself, to go through with it? How desperate did I have to feel, hoping that WEIRD CREATURE could show me how to get my wife excited in the bedroom again? He snarled. But that creature's story was just a LIE!

The unicorn's horn glowed more brightly, and the green, mostly naked bipedal creature rose into the air.

Its green lips opened. "Hey, Night Bright or whatever your name is? I can walk on my own. You don't have to help me--"

Night Light's magic levitation tossed the creature out the window.

Blearily, the unicorn slid out of bed. He shuffled to the window.

Tenth story room, he thought. When I checked in, the deskpony said it has a great view.

Night Light looked down at the street, far below.

He nodded with satisfaction. Sometimes, a hotel amenity is worth every bit and more.

Addendum

One day a world-weary horsewords writer remarked

Night Light calling an escort service only to have Twilight showing up at his hotel room. i have heard this story in so many different forms

I started making jokes like

Night Light calling an escort service only to have Twilight Velvet showing up at his hotel room.
Talk about complicated couple roleplay 🙂
