You were a bit nervous as you walked to Ms. Shelby’s class, having secured a job as her assistant. Though normally a member of the student body would act as her assistant, her position as the school’s Anatomy class required her to source outside help, someone who wasn’t “easily flustered” or “apprehensive” regarding the subject. The position apparently also had a high turnover rate, something that confused you when reading through the application, but the salary was great. Given it was an all-boys school she taught at, you imagined it wasn’t exactly easy to instruct a bunch of teenagers, but somehow her students were also some of the highest-scoring in the entire school. Something about it didn’t seem to make sense, but you certainly weren’t going to look a gift horse in the mouth. Walking into the room, you were instantly shocked by just how beautiful Ms. Shelby was when you finally saw her. She was a textbook example of drop dead gorgeous, and you couldn’t believe a hottie like her was teaching a class like this. She eyed you from head to toe, looking nonplussed, before you realized you had been staring at her breasts. You quickly averted your eyes.
“Ah, good. You’re here.” She greeted unceremoniously, drinking from her paper coffee cup before gesturing towards a chair. “Sit. Class starts soon, and I need to go over the basics.”
You silently did as she asked, sitting down across from her. Though you were still enraptured by her beauty, those feelings were now tempered by her commanding tone and serious expression.
“Now then, I assume you’ve signed all the documents in their entirety?” She asked, pointing at a copy of your application on the desk. You nodded, keeping your fists balled up on your lap as a bead of sweat ran down your forehead. “Good. Understand, this is a comprehensive course. I require you to act as a model for my classes, and that includes being in the nude. Understand?”
Though the thought of being naked in front of a bunch of other guys bothered you, you couldn’t say no to the job. Not to the job, its pay, or the beautiful woman offering it to you right now.
“Excellent. Drink this tea, all of it, then undress in the back. Once you’re fully unclothed, return to the front and sit next to my desk.” She ordered, pushing a cup of normal-looking green tea towards you. Part of you was curious about the darker color, but not wanting to disappoint your new boss, you downed it all in one go, walking into the class’s side room. Feeling a somewhat warm feeling in your belly, you forced yourself to relax as you took off all your clothes, carefully folding them up and placing them on a shelf. You couldn’t believe you were actually doing this. You walked back out, covering your crotch with one of your hands. Before she had even fully looked at your naked form, she struck your hand with her extendable pointer, getting a quick, sharp yelp out of you.
“None of that. You won’t make for a very good model if you’re covering yourself up.” She ordered, pressing the pointer against the underside of your chin. The warmth in your belly got stronger as she met your eyes. “From this point onwards, you are to follow each of my commands to the letter. That means no covering yourself, no arguing, and no touching. Understood?”
You meekly nodded, nursing the minor throb that now came from your hand. You sat on the cold chair, completely exposed, as the bell rang. Over the next several minutes, her students filed into the classroom, doing their best not to look at you, focusing on their gorgeous teacher. You wanted to squirm, but you knew better than to do that with Ms. Shelby keenly watching you.
“Quiet in the classroom!” She shouted with surprising ferocity, getting the few students who had been talking to each other to immediately shut up. “Now then, as you are all aware, today I have brought my new assistant here to act as my model. We’ll be going over male and female anatomy in full detail, and I expect you all to take notes and not gawk. Now then…”
She walked around you, extending her pointer again as she ordered you to spread your legs. You slowly did as she instructed, revealing your flaccid dick to each of the men in the classroom. As you felt your face go red, the heat in your belly went crazy, spreading throughout your whole body. You broke into an intense sweat, but Ms. Shelby paid it no mind. “Obviously you all know what this is. The male phallus, or penis. Though my assistant here appears to be… smaller than average, that will soon be irrelevant as we move onto the next part of the demonstration.”
You felt a brief “tightening” of sorts around your crotch as you looked down to see your dick actually shrinking in size. You couldn’t believe your eyes! “Pay attention! Watch as his penis shrinks, most of the body, or "shaft" as most call it, begins to invert, becoming the new walls of the vaginal canal. The gland, or "head" of the penis, will become a clitoris shortly.”
There was a sharp pulse that shot from your crotch to your brain, causing an equally sharp moan to suddenly escape from your lips. To your horror, you now sounded like a woman too, and the changes were only speeding up. “As you can see, my assistant has become quite wet. When aroused to a great degree, most women will "self-lubricate" in preparation for sexual activities.”
You began to pant as the heat continued to build. In the absence of your penis, you furiously wanted to rub your new crotch, but the tap of Ms. Shelby’s pointer stopped you in your tracks. Instead, you were overwhelmed by the loud pops that came from your bones shifting, giving you wide hips and a perfect pear-shaped bottom. “Women possess wider hips to assist them in childbirth, as well as wider and shorter pelvis bones, with a shallower pelvic cavity. Typically they also have more narrow shoulders compared to men, as well as an oblique slant to their femur bones.”
As you legs finished smoothing out, somehow still retaining their previous length, a pressure began building on your chest. Your panting became far more shallow and labored as two breasts began to push their way out, leaving you with a pair of heavy, D-cup tits. “A woman’s mammary glands are far more pronounced than a males, and genetics are the primary determining factor behind their shape and size. Though “aesthetically pleasing” to most men such as yourselves, they’re important for feeding newborns, producing highly-nutritional milk during pregnancy.”
As if on queue, you could feel an additional level of pleasure in your new breasts. You were immediately shocked by Ms. Shelby grabbing one of your breasts, squeezing your nipples quite hard. A small stream of breast milk shot out of your nipple as you moaned again, nearly spraying one of the students in the front row as she nodded to you, seemingly satisfied with the results.
“Finally, the face and head.” She refocused as the last of the warmth could be felt on your blushing face. You couldn’t see what was happening to your face at this point, but after everything else that had happened to you, it was easy enough to guess for yourself what it was. “Women’s faces tend to be more rounded than a man’s. Noses are smaller and more narrow, and chins are typically smaller and have more of a point to them with a V-shaped jawline. Though usually up to personal preference, most women also tend to keep their hair longer than men do.”
Black hair tumbled from your scalp to neck length, naturally curling itself. You were unable to focus on much as the eyes of all these teenagers practically danced all over your naked body. The feeling of being watched like this, like some piece of meat, was as clear as day. You didn’t want to admit it, but you seemed to be enjoying the attention they were giving you.
“Now, clothing. Up up.” Ms. Shelby suddenly instructed, getting you to suddenly stand up. Your new center-of-balance felt very off, especially with your new breasts hanging off of you, but you knew better than to disobey Ms. Shelby, especially after everything she had done to you. Without missing a beat, Ms. Shelby suddenly began helping you into “your” new clothes, obviously having been picked out by her to offer the most “enticing” view of you possible… while still clothed, of course. It wasn’t like these men hadn’t seen everything intimately at this point anyways. You found the clothes on your new body to be tight, but in a very pleasurable way, especially the underwear and stockings. You actually caught a glimpse of yourself in the mirror near the back of class, seeing you were just as gorgeous as Ms. Shelby now. Every part of your new appearance oozed seduction and sexuality. You pulled back on the edge of the shirt, seeing your pink bra strap as clear as day.
“Now, that concludes the physical presentation.” Ms. Shelby suddenly announced, causing you to slip out of your haze somewhat. “Now then, we’ll be having a test on all of this tomorrow! Those who score a 100% on it, including the bonus questions, will be given an extra credit course with my assistant here! I expect you all to do well on this tomorrow, so study!”
Your face suddenly went cold as you realized exactly what she was suggesting. Was she actually planning on… pimping you out to her highest scoring students? You quickly realized this must have been why her students did so well, but as you looked at all their horny faces, something in your brain began scratching at your virgin vagina. You realized they were turning you on too. You knew they all wanted you, desired you, and your new instincts were going wild, especially with their smell now noticeable in the air around you and Ms. Shelby. You wondered if she felt the same way…
