Jennifer can't wait to test it.

You look to Dr Marcos and raise an eyebrow. In truth there is no shortage of test subjects and the scientist's move to volunteer herself to assist in the test is unnecessary. However with the research conducted at the Chyoo labs the staff recruited tend to take a more active role in research than is normal in other fields.

"If you'll excuse me Dr John?" Marcos asks, and you nod and give her a smile in response.

Dr Marcos hurries from the observation room and a couple of minutes later enters the room to join Jennifer, who has been gently wanking the latex cock with a lascivious grin on her face whilst she waited for the Doctor. The athletic student looks Dr Marcos up and down when she arrives and her filthy grin widens and you note that the speed with which she is caressing the artificial prick increases.

"Sweet!" Jennifer murmers once she has checked out the scientist. "I don't usually go all the way on first dates Doctor, but in the cause of science..."

"Yes quite." Marcos responds, attempting to keep a semblance of professional reserve. "You are to follow my instructions. After we'll require you to record the feelings, both physical and emotional as part of our research data."

Jennifer simply nods, grinning at Dr Marcos in anticipation as the scientist begins to undress. Beneath her labcoat she wears a straight black, kneelength skirt and white blouse. She takes off the blouse to reveal a shear, lacy black bra. Her breasts are quite small, but high and perky. Through the thin black lace you see her nipples are erect and long in comparison to the size of her tits. She reaches behind her back to unhook the bra and her little breasts pop free. Each is barely a handful, but they jut jauntily forward with engorged dark nipples.

"MMM!" Jennifer reacts to the sight of the Doctors sweet little cones of girlflesh.

The tight black skirt slips down Marcos's slim legs and she steps out of it and folds it neatly. Her panties match her bra, but these are quickly removed. The Doctor is clean shaven or perhaps waxed, her sex dark in contrast to her pale skin. You see a tiny butterfly tattoo just above and to the right of her hairless mons and catch the glint of shiny metal in her clitoral hood. You peer closely through the mirror and see a piercing shaped roughly like a dumbell threading horizonally through the crinkled folds that cover her clitoris.

Dressed only in her short heeled pumps the Doctor lifts her tight little butt onto a table and raises and spreads her shapely legs, hooking her heels onto the tables edge.

"Now, if you could..." Marcos begins to say.

Jennifer though doesn't seem able to wait and as soon as the Doctor has spread her legs she moves forward, pushing Dr Marcos's legs wider as her hips push between the spread thighs. The scientist looks surprised and opens her mouth, but whatever protest or rebuke she planned to make is lost in a loud gasp as Jennifer without pause guides the rubber cock to the thin dark pussylips and pushes her hips forward. The black rubber shaft sinks several inches into the offered quim of Dr Marcos and Jennifer lets out a loud contented sigh as the black rod disappears up the cunt of the scientist.

"Oh fuck! That's just fucking awesome." Jennifer exclaims as she impales the nanoprobe laced dildo. "I can actually feel the heat and wetness of your pussy doc. This thing feels as real as if it was part of me."

"Very good, now I'd like you to move your hips backwards and forwards." The Doctor says, trying to regain her composure and reassert control over the test. Her words though are punctuated by low moans and gasps that betray her interest to be less than clinical detachment.

"No shit huh!" Jennifer laughs. "Doc I've used a strapon on girlfriends plenty of times. You just relax and let me handle the fucking."
