*Flashback Cont.*

You set the bag on the table and check her pulse; finding it steady, you grab the Stethoscope to listen to her heart beats. They were normal, and you pried open Darcy's eyes to check the pupil reaction before looking closer with the Eye Viewer. They were so pretty...even when she wasn't awake.

Satisfied, you move on to her mouth. Opening it wide, you shine a light inside to examine her maw...fascinated by her large throat. You make her tongue poke out of her mouth, letting it hang over her bottom teeth. You measure it to be at least as long as a humans. Placing it back, you lay your pulsing rod on her tongue before moving in and out of her mouth. Darcy's velvet tongue excites your pleasure and you go deeper...the tip touching the back of her throat. She gives a cough, but doesn't wake. You push a bit more, and the head of your rod is in her esophagus. Picking up speed, you ram her throat over and over until you cum right in her mouth. Darcy swallows out of instinct and you pull out of her Oral Cavity. "That was great, Darcy." You tell her, while pinching your hybrid sister's erect nipples. "I should have you give me a bj more often."

Moving on, you rub her firm belly and use the Stethoscope to listen to the sounds her stomach was making. Then moving lower, you hear the pulse just above her vagina. Putting the tool around your neck, you take out the beak-like object. Research told you it was called a Speculum; a device that allowed Doctors to view the insides of women. First through, Darcy had to be in a better position. So you made the chair recline, propping her feet up, before spreading her legs. A wet patch is seen on her bikini bottoms, and you untie them before casting the piece of cloth aside.

Darcy's vagina is revealed; free from it's protective covering, pink and throbbing. Adorning gloves again, you play with the clitoris which makes her slightly pant. After that, you spread her outer lips and see her Urethra and vaginal entrance. Then, you insert three fingers and move them in and out of her. Her panting starts to quicken and you withdraw your fingers to see them coated with her natural lubricant. changing the glove, you then stick the Speculum all the way in before opening her up. Her vagina muscles squeeze against the tool and you're given a good view of her Cervix. It's slightly open, and you can't help but touch it. A spasm rockets through Darcy and a moan escapes her. It makes you harden up from just hearing it.

Leaving the Speculum in, you pick up the other tool. You had found out that it was an Endoscope; a camera that allowed veiwers to see down drains and such. But in the Medical Field; they were used to see the inside of stomachs, intestines, etc. It had a screen hooked up to it, and you turned it on. When it was ready, you slowly inserted it into Darcy's Cervix...revealing her womb. It was so large...to think she'd have eggs in there one day boggled your mind! Once the Endoscope was removed and turned off, you slip a condom over your rod and enter Darcy. the Speculum was still in place, so you were able to hit her Womb Entrance clearly.

"I'm gonna examine you every chance I get, Dar!" You say, gripping her hips. "You'll be my female anatomy doll...I'll be good doctor thanks to you!"

You cum in the condom and clean up your sister, before dressing her again. She wakes up after an hour, and you tell her she got overheated from being outside too long. Darcy accepts your tale, and goes to change. Not knowing that you had many more plans in store...
