Keep playing doctor

"Hmm... We really should take your temperature though..." You tell Sarah, making her jump slightly as you abruptly break the silence.

"Without a thermometer?" She asks weakly, touching her cheek and grimacing a little as she realises how hot she really is.

"Well, yeah... I know a few ways... Though you might find them a little odd." You tell her, trying to sound both convincing and just enough embarrassed as you hold up your index finger before her.

"What...? With that...?" She wonders, staring at your finger with expected suspicion in her voice.

"Well... Yeah! I actually studied medicine when I was just a little older than you." You lie, smiling reassuringly at the girl in front of you.

She stares at you for a few moments, and you grimace slightly as you silently curse yourself for even trying something as stupid as this! Then, to your amazement, you see a small smile start to form on her lips, making cute little dimples appear at the corners of her mouth.

"Wow! Really...?" She finally says, adding a girlishly innocent tone to her voice, while her big brown eyes literally sparkle in amusement. Her nervousness suddenly seems to have vanished alltogether! "I didn't know that!"

"Well, I never graduated." You admit, continuing your silly little tale. "But I'm pretty sure I can still get your temperature!"

"Okay...?" She says, still smiling while glancing at your finger again. "So... What do you want me to do?"

"Oh, it's quite simple... You just need to open your mouth, like this..." You instruct, parting your lips and sticking out your tongue a little while thinking that there's just no fucking way in the world that you'll get through with this! "Then I'll just... put my finger in, and leave it there for a few moments, until I can estimate your temperature... If you're okay with that...?"

There are a few moments' silence while you just look at each other, both of you smiling while trying to read the other's feelings and intentions. Sarah still has that amused look on her face, and you wonder how far she'll play along with your little game...

"Well...?" You ask her as she slowly turns and put her empty wine-glass down on the table.

"Oh, I'm fully confident in your abilities, Dr.Doe!" She finally replies, still smiling and using that girlish voice while standing in front of you again, and you barely believe your eyes as she parts her lips and slowly sticks out her small, pink tongue for you!

"Thank you, Sarah." You reply, trying to hold both your voice and arm steady as you take a step closer and gently put your index finger on her tongue! After a final glance up at you, that is far from as innocent as her voice, she closes her eyes and allow you to slowly slide your finger into her waiting mouth!

Just feeling Sarah's soft, luscious lips close around your finger nearly makes your cock burst through the front of your pants, and it takes quite some self-control to keep from groaning as she, seemingly unconsciously, starts to suck on it while slowly bobbing her head back and forth!

Breathing heavily while fighting your sexual urges, you wait for two full minutes before reluctantly pulling your finger back, making an audible popping sound as it leaves her wonderful lips!

"Done already...?" She wonders, smiling innocently at you while wetting her lips with her tongue.

"Well... Yeah..." You say, glancing at your saliva-coated finger as if trying to read the results from it. "But this can't be right! You'd already be dead, or close to dying, if this was correct!"

"Oh, really?" She asks, acting worried while leaning a little closer to look at the finger from the same side as you do. "Did we do something wrong then...?"

"Well... I guess I didn't count upon your... natural hotness..." You tell her, glancing right down her generous cleavage.

"Oh!" She gasps, obviously trying hard to hold back from giggling at your awfully silly comment. "So, we'll have to try again?"

"Well, it's a little more complicated if the patient has passed the limits of hotness by as much as you have." You tell her, also having a hard time to keep sounding serious. The humor is low, but Sarah seems to enjoy it that way, so there's no reason to stop now!

"Okay, Dr.Doe, what can we do to get a better reading then?" She queries, the mischievous look in her eyes contradicting the sweet innocence in her voice.

"Well, we'll simply have to change to another..."
