Chapter 10 by Willbot Willbot

Which thermometer does she get?

Amanda's choice. (Big Rectal)

“No no,” the nurse waved at her dismissively, and then winked. “Your choice, hon.” She then resumed attending to the scale on which I stood, still totally nude, still totally erect. A bead of precum sat on my penis’s tip, which without warning, Nurse Olivia scooped up with the tip of her finger, and then lapped up casually, not even sparing me a glance, as if it were the most normal thing in the world. She wrote down my weight just as Amanda returned from the back carrying what looked like a thick glass tube, perhaps an inch or an inch and a half in diameter. She held it up for us to see.

“I got the big rectal one,” She explained, cheerfully.

What!?” I nearly swallowed my tongue, “That’s a thermometer?!

Mrs. Olivia merely nodded at my inquiry, and turned back to Amanda, “I thought so, you naughty minx… make sure to not skimp on the Vaseline, now.” She led me by hand to where Amanda was sitting down, holding the ridiculously large rectal thermometer and a jar of Vaseline.

That won’t fit in my... my...!” I attempted to argue.

Amanda shook her head, “No, it will… trust me…” She opened a jar of Vaseline and stirred the tube around in it until it had a thick coating of it. “You just have to lube it up real good and…” She glanced around for something on witch she could demonstrate this, eventually realizing she herself wore no pants. She jammed it up her own butt in one smooth motion, obviously no stranger to its girth.

SeeeEE!? Oh… OH!” She pulled it out again, panting. “Not a bad feeling, once you get used to it… Feels good, even.” Mrs. Olivia was pleasantly giggling at her assistant's lustful antics. “Oh, come on, Mrs. O, you know it does…” She stirred it in the Vaseline again, until the coating had thickened back up again. “Alright, bend over my lap.”

I hesitated, not knowing exactly how she wanted me. "Over your lap?"

"Come on, didn't you ever get spanked as a kid? Face down, bottom up. Assume the position."

I did, and I could feel the very tip of my dick pressed up against her pubes, practically pulsating with involuntary horniness. This position had me exposed to the world in such a way that simply being naked had not. Mrs. Olivia affectionately stroked my butt, then when I was relaxed, gently spread my legs even wider until she was able to lightly stroke my asshole with a single fingertip.

"You ready for your spanking?" Amanda asked jokingly, receiving only silence in return. "Oh come on, lighten up people. Alright, John, on the count of three..."

“One… two… THREE!” Amanda stuck the whole length of the thermometer into my ass all at once.

Unggth!

Wow! Now that’s a tight squeeze!” Amanda said, delighted, before both her and the nurse broke into a giggle fit. “Anyway, John, this thing takes maybe ten minutes to register its temperature if you just leave it alone, I guess due to its being a little larger than most thermometers." That last part was a pretty big understatement, I thought, being keenly aware of the foreign object in my rectum. Amanda glanced at the clock on the wall above the seating area of the waiting room. "You might have to skip homeroom though..."

Does she leave it alone?
