"...reading spot!"

"Okay...?" Sarah says, acting quite shocked. "So... Umm... Where, more exactly...?"

"Well... The most accurate place to take one's temperature, would actually be... inside one's rectum..." You tell her, hesitantly but truthfully.

"Oh...?!" She gasps, not just playing this time, while staring at your thick index finger. "O... Okay...?"

"So... I understand if you'd not be willing to try that..." You tell her, giving her an understanding smile while mentally slapping yourself in the face for trying something stupid like that.

"No, no...! That's fine...!" She interrupts you, looking a little stressed but at the same time starting to get that amused look back in her eyes. "I mean... You did say I could be close to dying, right...?"

"Well... Yeah..." You admit, trying to search her big brown eyes for clues to whether she's messing with you or not.

"So... I suppose I'll just have to trust your expertise, Dr.Doe...?" She mumbles, biting her lip a little while looking back at you.

Swallowing deeply, you nod vigorously while looking her incredible body up and down. "Well then, Sarah... If you'd please get over here, and kneel down on the couch...?"

"Okay..." She replies, smiling shyly at you while passing you and standing in front of the couch. "But... Shouldn't I remove my jeans first...?"

"Well, yeah...! That could help, I guess...!" You answer, your eyes locked on her tight ass while she unbuttons her pants and slowly wriggles them off of her hips and down her slender legs! Thinking your brain is about to explode, you watch her bend over, with her beautiful behind completely bared before your eyes, except for that tiny little g-string, then step out of her jeans and climb up onto the couch, leaning herself over it's back.

Looking back at you over her shoulder, she gives you another shy smile while slowly moving her legs apart, giving you the most beautiful view of a string-clad piece of ass that you've ever seen! Barely able to breathe, you step closer and shakily reach out to gently place your palm on one of her wonderful buttocks, letting it rest there for a while to savor the feeling of her hot, firm and naked flesh!

Still holding onto Sarah's butt, you put one knee on the couch to give you support while leaning down to get a better look at her most intimate parts. Then you hook your finger under her g-string and follow the thin garment downwards while pulling it out of her asscrack, and eventually out of her well-shaved little pussy as well! Staring in disbelief right at her steaming wet slit, you lose hold of her slippery string and let it smack in place just a little to the left of it's previous location, making Sarah yelp in surprise while leaving her genitals exposed...!

"Sorry for that..." You mumble, still staring. "Umm... Well... You look just fine down here... So... I guess we could go on with the... temperature reading...?"

"O... Okay..." She replies, quite nervously. "But... Don't you need some... Lubricant...?"

"Yeah, of course... I was just about to get some, but I see that we already have quite a lot right here..." You tell her, gently placing your fingertip at the top of her snatch and then slide it slowly downwards along her dripping wet slit!

"Oh!" She gasps, wriggling her hips and clenching her buttocks as you keep running your finger up and down her soft pussy-lips.

"Stop that!" You tell her, giving her a playful slap on her ass. "You must be able to relax, Sarah! Here! Put your hands down here, and then just lean forward and relax while holding your buttocks apart, okay...?"

"O... Okay..." She says, looking back at you over her shoulder. She's clearly nervous about the whole thing, but as you look up into her eyes with a reassuring smile, she smiles back at you and then follows your instructions. Grabbing onto her own firm buttcheeks, she lets her body relax and rests her weight against the back of the couch while pulling them apart, exposing herself completely to your probing fingers!

"Good girl!" You tell her, staring right at her puckered sphincter while resuming your gathering of lubrication, hearing her groan slightly in response as you "accidently" rub your finger against the most sensitive part of her delicate pussy! Not able to pass up on the opportunity, you then place your finger right at the opening of her love-channel and slowly but firmly push your way inside!

"Hey...?!" She gasps, bucking her hips forwards, but without letting go of her ass-cheeks. "Isn't that the wrong place...?!"

"Yeah, of course!" You reply patiently while following up on her movements and eventually pinning her against the back of the couch with your whole finger buried inside her velvet pussy! "But I still need a little more lubrication, and this should be the best way to get it..."

"Oh...! O... Okay...!" You hear her grunt in reply, a hint of pleased amusement in her voice while you make sure that your finger will come out covered in her juices by gently twisting it around inside of her!

Now it seems like you have two things to chose from, both sitting right in front of you. The question is, which one of them do you pick...?
