A 'practical' rule

The class was only teorical in nature, so you decided that a practical lesson wouln't do any bad.

Old rule: Biology class involving the sexual response of femboys will be prectical, only if harm isn't meant.

"Ok, class enough reading, i need a femboy to make a demonstration, who wants to come here" overcomed with excitement, you raised your hand. "Alex, ok then, come here and bent over my desk".

While going to the desk you remind your teacher your new name as he must have slip up, he only rolled his eyes slightly and told you to get your shorts and panties off, getting you half naked in front of the classroom, with only your semi-hard dick going through the fishnet and your blouse.

"We'll start with the stimulation, Alexa bend over, please" doing so, leaved your ass exposed to the whole class and the expert hands of Mr. Santiago. "As you can see, Alexa here, already is quite prepared" he said, rubbing his finger in your already wet vagina. "But it may happen that a femboy, much like a woman, needs to be prepared with some kind of foreplay, be it dirty talk or humilliation, this is to make the asshole of a femboy wet enough to make the insertion of the genitalia easier." He inserted one finger inside your vagina, making you leave a moan"Any questions so far?... yes, Sofia?

"Why are we having a class where a femboy is being sexually stimulated and not a woman or a man?"

"That's because the femboys mutation was and is still recent, just 21 years ago femboys didn't exist, your generation wasn't educated on how the femboys worked, or did you?" asked Mr. Santiago.

"No i didn't, but still, he's getting all the fun for himself!" Protested Sofia.

"That's because in this class i am going to show you how to sexually stimulate a femboy, and in the next one you and the rest of the class will do it to the other femboys in the class" when Mr. Santiago finished explaining, cheers filled the classroom until he shut them up.

"Now we see insert the finger to search for the prostate or the g-spot whatever you want to call it, for the g-spot is pretty easy you just have to push your finger to the direction of his dick until you find it, and you will know it's his g-spot when-"

Aaahh

You mouth let out a loud moan when Mr. Santiago pushed your prostate, feeling your legs tremble and your dick dripping precum.

"That happens". He said as he took his fingers out of your vagina

"Mr could you finish it, please?" You ask

"Unfortunately class is over, Alexa" as he finished talking the bell ringed. "Put your clothes back on and get back to your seat". He got close to your ear and whispered "i will show you biology in detention you Slut".
