Thankfully for Alice, it's brief

Alice couldn't believe that there was a boy who had his tongue inside her pussy! She watched as Dane pursed his lips, and sucked up her juices, then moved his tongue up to play with her overstimulated clitoris some more. Just as Dane was starting to get a rhythm going, the bell rang.

Mr. Humphry jerked in surprise, and looked down at his watch. "Well now, it seems that we've let time get away from us.", he declared. "Thank you for your participation today, everyone. I think we've made really good progress towards a better understanding of sex for you all." The students grumbled in disappointment that class was over, and began filing out. As they left, some brazenly copped a feel of Alice's breasts once again. Alice grew worried, as Mr. Humphry didn't say anything to these boys, even though, technically, class was over. Did that mean that they were allowed to touch Alice even outside of the confines of the lesson?!

Dane licked one final lick, as Humphry approached and shooed him away. Alice was finally able to close her legs, and she began rubbing them, as they were sore from being held apart for so long.

"That was one of my best classes yet, Alice!", Mr. Humphry said with a smile on his face. "The students were engaged, and I think they really benefitted from the hands-on experience that you provided!"

"I guess so...", Alice mumbled

"So, that being the case," Humphry continued, "I'll be speaking directly to Principal Davies to see if we can get an extension for this experiment that you and Mrs. Sylvia have cooked up! I'd love to have you as a nude, practical model for tomorrow as well. We can work on oral sex, mutual oral stimulation, and even vaginal penetration with the penis!"

"What!", Alice yelled. "Mr. Humphry, what do you mean!? V...vaginal p....penetration? But...you don't mean that...you would let the boys put their penises in me, do you?"

"I don't see why not!", Mr. Humphry continued. "It will be valuable firsthand experience for everyone involved!"

Alice's blood turned cold as she realized that Mr. Humphry planned on letting the boys in her sex ed class literally have sex with her!

"Ummm....but it's important for us to learn about proper protection, like condoms and birth control too, right?", Alice asked, hopefully. "B...because I don't want one of the boys to get me pregnant tomorrow!"

"Well yes, of course, Alice. All of the proper protections....", Mr. Humphry trailed off, as he furrowed his brow in thought. "Actually....actually, yes, that might work. We could have the boys ejaculate inside of you without any protection instead. If all of them manage to do so, it will be incredibly likely that you'll become pregnant with the child of one of your classmates. That way, we can follow your pregnancy through all of the stages! You would be the ultimate practical sex-ed model!"

"Anyway, Alice, you have other classes to get to. I'll see you tomorrow, and we can talk about what you should do in order to prepare for your pregnancy then."

Her teacher ushered her out of the classroom and closed the door behind her, leaving her to stare in shock as she considered the fact that her teacher might be forcing her to get pregnant tomorrow!
