Yuki walked into a classroom the next day, where many students were standing around a long bench in wait for the model to arrive, since the news of a live model leaked out earlier, over half of the attendance was comprised of horny male students, but the one that caught Yuki's eye was Trisha and her gand, who were sitting at the front row, obviously here to witness the utter humiliation of Yuki on this day.
"Hello Yuki, I'm so glad you made it, I just want to tell you what a noble and brave thing you will be doing" Ms. McIntyre, the biology teacher, welcomed Yuki in, almost as if she was afraid Yuki was going to bolt any minute now, and to be fair, Yuki had half a mind to do just that, Ms. McIntyre inched in to whisper one more thing "And I would like to assure you that your grades in my class will be quite excellent."
If not for the whole thing sending Yuki's stomach churning, she would have felt almost dirty at the awkward attempt of compensation, but she didn't have time to feel awkward before Ms.McIntyre launched into a pre-amble on the female reproductive system, and once she was done, she instructed Yuki to begin disrobing and lie down on the bench.
Yuki began removing her clothes, a knot forming in her throat as little by little, Yuki's modesty was stripped away along with her clothes until she stood completely naked in front of an entire class of students, she walked up to the bench and lay down on the cold, hard surface, as the teacher once again began explaining the details of the female anatomy, worst of all is the physical implementation as she explained the concept of female arousal by pinching away at Yuki's stiff nipples, pointing out her erect clitoris poking out of its hood, and showcasing the full body blush that, the teacher said for some reason, Yuki was now developing, the comment was meant as a joke by her, to which many of the students found chuckle-worthy, although Yuki certainly didn't, it only further developed said blush.
"Now Yuki, if you may please spread your legs." The comment came rather gingerly from Ms.McIntyre, but it hit Yuki like a ton of bricks, she was this close to crying, but after a few seconds, Yuki slowly complied.
The teacher once again began describing the details of the reproductive system using Yuki's own pussy in great specificity, the teacher even spread her lips open to show the rest of the students what the insides look like, Yuki raised her hands to cover her face in shame, not that anyone noticed with a much more critical area revealed, not to mention the fact that all the poking and prodding at her genitals was getting her rather hot and bothered.
Yuki did not know whether to consider the next part a salvation or a further humiliation, or perhaps even both, but by then her judgement was clouded by her own arousal and horniness, Ms. McIntyre announced one more thing:
"Now Yuki, this will be the last thing in today's class," She began "Class, Yuki will be showing us..."
