Yes

I dashed to the Med Room and pretend I had just gotten there, while looking through the drawers. I found a few more Dildos; each a different size, and one had an Endoscope attached inside. Next to those was a Pocket Watch of some kind. It had a large red button on the top...

I did have time to look at it more because Becky came in. "Becky, what's up?"

"I feel...strange." She said.

"Oh? How 'strange'?"

Becky untied her hair. "My whole body is throbbing...my head's spinning..."

I tell her to sit on the exam table before grabbing the Thermometer and Stethoscope. "Do you feel pain anywhere?"

"No. But my throat feels scratchy." Becky admitted.

"Hmm...let's take your temp." My sister puts it under her tongue, and I place the end of the Stethoscope below her collarbone. Her heart is calm now, and steady. I put the Stethoscope around my neck when the Thermometer beeps, and I check the reading. "Seems normal...I should have a look at you-"

"Mike, I don't think-""

"Unless you have a better idea?" I ask. "If I see something wrong I call for help. Okay?"

There's a moment of silence before Becky nods, and removes her robe. I slip on some gloves, and turn on the overhead light.

"Open up, Bec."

She does and sticks out her tongue.

"Open wider...wider...good. Let's see here...hmm...throat seems dry." I put two fingers on her tongue. "Say 'ahh'."

"Ahh~"

"Cough."

"*cough*"

"Hmm...I'll need a closer look." I tell her, while removing my fingers.

"Huh?"

I show her the Endoscope, with turning on the monitor. "With this, I'll see the back of your throat. And I'll also see if there's something there that's hurting you."

She reluctantly agreed, and opened her mouth again.

I slid the Endoscope Dildo inside, gently, and look at the screen. the camera showed her palette, tongue, uvula, teeth and tonsils. Going a bit further, I see the back of her throat. It had some saliva there. "Seems alright." I remove the tool from my sister's Oral Cavity. "Just dry."

then I had Becky put her feet in the stir-ups, before I inserted two fingers and felt around. "Any pain?"

"No, b-but my head is spinning."

"You're awfully tense, Becky." I tell her. "Relax."

I stick in a third finger, and moved them in and out of Becky's pussy. "How 'bout now?"

"N-No. Feel-Feels nice actually..."

A few minutes pass, before I stop and open her up with the Speculum. "This looks ok, too. Maybe you're just stressed."

"Maybe..."

I remove the tool and feel inside her again, she bit her lip as I did. "I can't find anything wrong, but you just need a good rest." I remove my hand and bring her some Strong Sleeping Pills. "Take these..."
