After a long time of not being able to attend school in person, my first day back to high school was nothing like I had expected it to be. Most of my day had been normal, but I had one class that was the most strange and the most wonderful thing I had ever experienced. Adv. Bio had started off with a rather rough reception from my new classmates, but after a few explanations from a very helpful hippie teacher I was given the most amazing show of my life. My seven incredibly hot classmates had all stripped down to their bras and panties, showing off their fantastic bodies.
The only downside to being able to witness this spectacular show was that I had to undress down to my underwear as well. Unfortunately I had chosen to wear a rather loose pair of boxers, and my arousal from seeing so many sexy girls was quickly apparent from the tent in my underwear. This became an even bigger problem when my excitement caused me to get far too distracted, which earned me the disappointment of my very attractive teacher.
Thankfully my teacher didn't have an issue with my boner, just with my lack of attention to her teaching. She gave me a chance to relax and relieve all the tension my overexcitement had caused. Ms Skye led me into a slightly separate room, and the while she stood behind my back she skillfully coached me through masturbating. The teacher pressed her soft curves against my body and used the most sultry voice to whisper seductively to me, planting lewd ideas into my mind as she encouraged me to jerk off for her. When I spent my load into a cup she took it, though I can't be certain she made it seem like she disposed of my cum by eating every drop.
That was only my very first day in the class, and there was the promise of so much more in the future. Though we didn't get much learning down that first day, I had quickly surmised the goals of the class. Though I had only joined halfway through the class, it was clear the teacher wanted to share her philosophies of hedonistic free love and lack of all inhibitions. The girls of the class had already learned the theories in the first semester, and I had joined just in time to start participating in the practical demonstrations. I was almost certain that I could use these practical demonstrations to have some very lewd and erotic experiences if I was crafty enough. All I had to do was obey the teacher and use her uninhibited ideas to my own advantage.
In order to catch up with the philosophies the girls had already learned and accepted I had to read some fairly dense books on some rather fringe theories. I expected to just read them in order to be able to satisfy Ms Skye, but when I cracked open one of the books after the first day I found that I actually quite enjoyed digging into these new ideas. They definitely were pretty wild, and the things they advocated for were far too lewd for the mainstream to ever accept, but the possibilities they presented were undeniably intriguing. Some of the ideas discussed included the complete abolishment of clothes altogether outside of articles needed for harsh weather and the destigmatizing of public sex in adult only locations. One of the most radical books advocated for the adoption of a free use society for all adults. Most of the policies the books pushed for were the type someone living in a polyamorous nudist commune would enjoy, but the writers of the books presented them with sound logic and reasoning.
When I arrived on my second day of school I was beyond excited to see how we might start doing practical demonstrations of these types of ideas. I got to Adv. Bio class before anyone else. While I waited for my classmates and the teacher to arrive I stripped down to my underwear. Because of the problems with how obvious my erection had been the previous day I wore a pair of much tighter briefs. Since the classroom was a partially remodeled locker room, I put my clothes in one of the remaining lockers.
My classmates came in one by one, and once they arrived they each gave me a wonderful show as they undressed down to their bras and panties. Most of the girls seemed at least somewhat uncomfortable stripping down in front of me, but even the girls who despised my presence the most didn't hesitate. The dress code had been enacted by Ms Skye, and the whole class obeyed her will with an unyielding loyalty. Even if they disliked being half naked around me, no one was willing to risk disappointing their cherished teacher. It was this dedication to obeying the teacher that I hoped to use to my advantage.
Ms Skye arrived at the class shortly after the last of my classmates had come in and undressed. Seeing that we all had changed into the dress code she gave us a warm greeting and then assigned us seats. Instead of normal school desks we were seated in a variety of couches and loveseats and formed a half circle facing the front of the room.
The teacher started the class off with a quick discussion of the reading we had been assigned. I mostly paid attention and engaged in the discussion, but I also made sure to enjoy the view of the incredibly sexy girls around me. There was Artemis the rebel, Brittney the cheerleader, Nancy the nerd, Kennedy the star athlete, Eden the pastor's daughter, Mackenzie the popular mean girl, and Jade the darling of all the arts departments. The girls were all leaders of their respective cliques, and they all had amazingly fantastic bodies on display. I was glad that my underwear was tight enough that it mostly hid my growing erection.
After the discussion Ms Skye announced that we would start the first physical activity of the class. My excitement grew to new heights, and I was eager to see what sort of lewd idea we would put into practice. To my disappointment the activity was far less hands-on than I had expected. After having read sections of the books the class had studied, I had guessed that the practical demonstrations would be fairly intense, but Ms Skye simply led us in some basic yoga poses.
Doing stretches and bending in awkward positions started off as a letdown, but after my initial disappointment faded away I began to appreciate it. The poses Ms Skye instructed us to do gave me some very alluring views of my classmates, providing angles that I hadn't known would be so exciting to see. I wasn't all that flexible, but some of the girls could bend and fold themselves in ways I didn't think were possible. My mind went nearly crazy imagining just what someone could do to have fun with those sorts of poses.
The yoga session took almost the full length of the class. By the end of it I was feeling fairly sore, though also nicely refreshed. I was also somewhat sweaty from the exertion, and so were my classmates. I was now beginning to understand why this class counted as a physical ed credit as well as a biology and philosophy one. Ms Skye noticed her students' sweatiness, and she invited anyone to use the adjoining communal shower if they wished to. I wasn't surprised when no one took up the offer. The girls might have been able to put up with being in their underwear around me, but getting naked and showering was still a step too far. My classmates and I just dealt with the perspiration and dressed in our regular clothes at the end of the class.
My second day of class hadn't been quite as exciting as the first, though I was thankful that I hadn't been called out for my arousal and forced to masturbate. But the lack of the exhilarating new experiences I had expected had disappointed me slightly. I had thought that if we had started off with getting half naked, then we would progress to far more sexually involved activities fairly quickly, especially considering the radically sex positive ideas in our textbooks.
After a little more contemplation I came to the conclusion that I had been far too presumptuous with my predictions. Having the class strip down to their underwear might have been my first day in the class, but it had only happened after a full semester of ruminating on the ideas Ms Skye was teaching. Any further steps forward would probably come at a slow pace as well. I decided that this wasn't all that bad. There were still so many incredible things for me to enjoy about the class already, and there would be plenty of time for me to use the sexually liberal ideas Ms Skye was teaching to my advantage.
The next few classes went by without anything too crazy happening. One day we all gave each other foot massages to encourage empathy and grow more accustomed to providing physical comfort to our peers. Another day we spent coming up with compliments about all of our classmates. Each compliment had to be unique and specific, and they had to be about our physical bodies. That particular class was the source of a lot of blushing, especially with how Ms Skye preferred we use less clinical terms for body parts. Instead of breasts or buttocks she wanted us to say tits and ass, and she heavily encouraged the subject of the compliment to showcase whatever body part was being praised.
As the days went on Adv. Bio was strangely becoming just a normal part of school for me. It was still undoubtedly the most exciting and arousing part of my day, but it had stopped being some erotica fantasy and started to feel more natural. My classmates appeared to feel this as well, as most of them looked far less uncomfortable when they undressed around me. It was a casual thing for them to strip down to their underwear, and I started to even develop friendships with my classmates.
I was able to chat idly with Kennedy or Jade as we got half naked, not caring how much of our bodies we were exposing to each other. I could gossip with Artemis or Brittney about the latest school drama, and the fact that we were in our underwear wasn't an issue. Mackenzie and Nancy remained quickly prickly towards me, Mackenzie especially, but the others had stopped treating my presence in the class as an intrusion. Eden oscillated between being the most friendly towards me and shunning me entirely, though I could tell her hostility was an act she forced herself to perform. But despite how friendly or cold the girls were to me during the class, no one said a single word about what we did outside of the classroom. There was an unspoken agreement that everything that happened in Adv. Bio was secret, kept hidden from anyone not a part of the class.
At the beginning of the second week of classes I thought I knew what to expect out of the strange class. That's why when I entered the classroom I was so surprised to see something new in the middle of the room. The couches and loveseats had been pushed back and in their place were two small beds on wheels, which looked like they had been borrowed from the theater department. About half of my classmates were already in the class and undressed. They were looking at the beds with as much confusion as I felt, so I knew that this was as unexpected for them as it was for me.
The rest of the girls were similarly surprised by the classroom's new features when they arrived. As everyone stripped down to their underwear and waited for Ms Skye's arrival we chatted about what the purpose of the beds might be. No one had any solid clues, so all of our ideas were just wild speculation. But I was happy to hear that some of the girls had predictions that were just as lewd and erotic as some of the things I was imagining. It seemed like I was not the only one who guessed this class might just go down a far more intensely sexual path.
