Deer

"...A Deer. I've always loved them."

I quickly glance at the shelf and find a bottle labeled 'Deer', carefully I take out a pill and have her swallow it.

My sister falls onto the exam table and cries out in pain, as her legs become the hind legs of a deer. Fur covers her back, ending at the small tail she now receives. Ears point up and stick out on either side of her head...

Becky pants heavily as I help her sit up; completely struck dumb by her beauty.

"You ok?"

"Sore...but...ok."

We then begin the exam and I took notes on what was different: reflexes were quicker, teeth were now that of a herbivore, blood pressure slower, and lastly her hearing was sharper. After using the ultra sound, I had my sister spread her legs. I slipped on gloves before feeling her outer lips.

She trembled a bit, then calmed and allowed me to continue. I spread her lips apart to see her Urethra and her Vagina...taking it all in, before inserting two fingers. My sister moans softly; clearly liking the massage. She plays with her breasts as I put in a third finger, back arching...

A gasp escapes Becky when I hit her G-Spot, and I feel her getting hot. I withdraw my fingers and insert the medium sized Speculum; opening it all the way. Her womb entrance is open slightly, and swab it with a Q-Tip. Then I close her up and help Becky down, before having her bend over the table.

I enter her, enjoying the warmth of her Vagina as it clenched around me. "You feel so good, Bec."

"Hah!...Th-Thank you, Doctor. AH!"

"I love examining you, Becky..."

Becky moaned. "Then please...examine me as much as you want!"

"I will!"

I cummed on my sister's back, then had her clean me with her tongue. The pill would last another two hours, so I hooked her up to the EKG and took more notes as she gave a blow job. Then I took her anally, which I cummed into her intestines.

Once everything was cleaned up, I took Becky to her room. But making her remember her promise to examine her whenever I wanted.
