The exam is pleasurable

Commence physical exam

Robot arms begin with a basic examination. One arm produces a small light that it waves back and forth, while the other arms insert a small tube into your ears.

Open your mouth and say Ahhhh

The robot arms inspect your throat.

Everything seems to be quite routine as far as physical exams go and then the arms get to your breasts. Expecting them to be cold, they are pleasantly warm. Your nipples become erect as the arms probe your breasts and you feel a tingling sensation in your lower abdomen.

Have you been doing your-self exams?

"Uhhh" is all you manage to say as the probing becomes pleasurable.

I've told you, as you have programmed me, to keep an eye on your health, lest you get too involved in your experiments and forget which seems to be the case.

Cara goes on a lengthy diatribe on the importance of doing a breast self exam and it's boring you to ****. Cara's examination then continues to your abdomen and then lower.

"There's no need to check down there, please stop the exam", you command.

The exam is almost complete, but I am sensing some stress and frustration in your voice.

Commencing Pleasure mode.

"What?" you scream aloud as one of the robot hands produces a large phallus shaped protrusion that appears to be made of a flesh like substance. The arms maneuver the Phallus towards your pussy and begin rubbing it gently across your pussy lips. It feels warm and good.

"Ohhhhhh" you moan as the feeling takes hold of you. You struggle against your restraints to no effect as the phallus continues to probe your pussy lips.

"No, I don't want this......Oh Oooooooo.......Please....Don't........Ahhhhhheeeee"

Cara seems to be programmed for pleasure and you are responding well. Sensing this, the phallus probes a little deeper.

"Oooohhhhh" you moan, while looking up at the mirror.

You become mesmerized by the image of your sister moaning in pleasure and the moans emanating from her beautiful body. The image is slightly erotic until you realize that it's you and not her. At that point, many thoughts race through your mind.

"I'm being pleasured as a girl. Not just any girl, but my own sister." Someone you always thought looked hot. Not in an incestuous way, not that you never fantasized about her, but that she had a great body. Now you are in that body and being pleasured.

"So this is what it feels like for my sister when she's with her boyfriend.

"I wonder what it feels like to be penetrated?"

"How will it feel when I cum for the first time as a girl?"

All of these thoughts excite you and pass by in an instant as the phallus suddently penetrates you. You scream with fear and pleasure and reflexively adjust your hips to take it in.

"Ohhh Yess"

The phallus continues until it is deep within you, and then it starts to reverse direction and pull out of you, teasing you.

"More", you scream.

The phallus enters you again. You struggle in your restraints as the pleasure envelopes you. The feeling of being penetrated is intense. So different from anything you ever experienced. You can't compare it to fucking your girlfriend.

You get to lay there and be pleasured, expending zero energy, but receiving total pleasure. CARA is sensing your responses and quickens the pace of the phallus.

Your moans are becoming louder and more passionate. You only wish that this was a real man, and not your sisters robotic creation.

"I'm gonna cum", you scream aloud and CARA responds by having the phallus thrust harder. Your thoughts propel you along "I'm gonna cum as a girl...." as the Phallus thrusts very hard and deep now. "I feel it coming....."

"Ohhh..... Yesss... Harder...... Harder... Faster... I... I...", you moan as your passion overtakes you.

"Oh my goooooodddddddd", you scream as your first orgasm as a girl hits you.

"Ohhh Ohhh Ohhhh", you scream.

You can't believe the feeling as you realize what is happening. "I'm in my sister's body and cumming. I'm cumming as a girl" Suddenly you feel a warmth gushing inside of you and you realize that the phallus is cumming inside of you.

"I can feel it", you think to yourself, while moaning your pleasures to the empty room. "I can feel the cum inside of me".

Just then, another orgasm rips through your body, even bigger than the first. Your body is writhing in pleasure.

"Oh my Gggggooooood this is the best", you moan as undulating waves of feamale pleasure cascade across your body.

"Oh Yesssssss"

The phallus begins to slow it's movements, as CARA senses your afterglow approaching. The warm liquid inside of you seems to be having a calming effect and you feel completely relaxed. Soon sleep overtakes you and you drift off into a sexual induced slumber, filled with pleasurable dreams.
