I was an average male health teacher. My students could do what they wished most the time. I was more of a counselor than a teacher. One day John came to me because he was worried his experiment to get into a megacorp pharmaceutical company I didn't recognize the name of wouldn't work because he needed a human test subject. I decided I'd be the test subject so I took the pill home. After work I drove home without incident, I ate dinner took the pill and took a shower. My body began changing while I showered the fat on my stomach vanished becoming flat. I yelped as I shrunk 6 inches to a diminutive 5'4. My face softened turning into that of beautiful women in her mid 20's. My hair grew out and became blonde tumbling infront of my face as screamed my voice raised up a few octaves. My arms and legs thinned becoming delicate and lithe. I buckled over as my waist constricted becoming thinner giving me a defined hourglass figure. My hips widened while my butt inflated like a balloon but when touched it would feel like a soft pillow. My chest became sensitive and bloomed out from under my hands to DD-cup breasts. Finally as I reached for the last vestige of my previous self it began shrinking and sliding inside me forming ovaries with eggs from my testicles, and a clit from my dick leaving a burning hot wet slit where my dick was. The hot water flowed down my body hugging my curves touching my body just right I massaged my new breast while rubbing my clit I collapsed to my knees as I sprayeda mist into the air. Turning off the shower afterwards collapsing in my tub. I went to my class to teach about sex ed up close.

I walked in the door in a blue button up and kaki's with white lacy underwear. my first class was all boys including John, most where surprised at my new form. I explained the process of reproduction at the end of which I asked John to come forward for a demonstration. I told him to begin stripping as I removed my pants and button up revealing my white panties which were soaked with my anticipation. "You all can join in whenever." I said as I sat on my desk and spread my legs for him to thrust in. His dick spread my lips apart as my legs wrapped around him. His thrusts hit my body in various spots. "As you can see ugh ugh he is using his dick to ugh hit me in various spots that cause me pleasure." I said 1 other student got up and placed himself behind me and thrust into my ass widening it painfully. "Something you all should know is anal is not always pleasureful ugh for girls do to the fact they lack th-." They began playing with my boobs while the sped up their thrusting quiteing me. "Anal gland men ugh have." I got through those words through the numbing pleasure as I came tightening my body causing them to cum into me. "Let's do this every morning guys." I said while I cleaned myself up putting back on my clothes.
