The(O) Condition - Chapter 09

THE(O) CONDITION

Chapter 9: Theo’s Anatomy

“Did you really volunteer to be a model for the anatomy class?”

“Sure did. Why not? Gallan said it could help with our grade, and believe me, I’ll need it.”

“Yes, but aren’t you afraid it’s going to be risky for you?”

It was Monday morning, and Theo and I were walking to the building where classes were held.

He had bust a nut in our bathroom right before we left. The usual.

“Risky? In what way?”

“Gallan explicitly said that this might involve getting naked in front of everyone. Full-frontal nudity, he wrote in his email!”

“Why should I be afraid of that? I have no problem being naked. I don't know if you've noticed, but I have the goods to pull off the birthday-suit look!”

Speaking of which, his junk was already bouncing in his shorts.

“I don’t doubt it, but that’s not the point. Aren’t you worried about getting hard?”

He sighed.

“Yeah, I know. But I have a half-hour break before anatomy, so I’ll have plenty of time to empty my balls fully right before walking into class. Besides, it’s only one hour. I’ll manage.”

“Well, if you're feeling confident about it, I won’t try to change your mind.”

Theo wrapped his arm around my shoulders as we walked.

“You don't have to worry about me all the time, buddy. I know what I’m doing, and you know I’ll ask for your help if I need it.”

“Right. How was the doctor's appointment by the way?”

“It was actually the main reason I went back to my parents’. Dr. Filler has been following me since the very beginning, and we meet every month to assess how things are evolving.”

“I see. And…? How are they evolving?”

“Nothing new under the sun. It was just the same old tests. The O Condition is so rare that I’m basically Filler’s guinea pig.”

“His guinea pig?”

“His test subject if you will. I spend half of the day at the hospital, I masturbate a few times, and the medical team analyzes my semen. Sometimes, other people watch as I jerk off.”

Theo's casualness never ceased to amaze me.

“Really?”

“Yeah. It's all for science, bro. Besides, there’s always sexy nurses around. Not gonna lie, it’s fun giving them a show while I beat my gigantic meat. I can see it in their eyes— they want it so bad.”

“You think everyone’s into you, do you?”

“As if it’s not true? I bet those slutty nurses think about me and my young horny fat cock when they get ploughed by their boring husbands later on. They must be so disappointed with what they have at home and the measly amount of cum their men can produce.”

I rolled my eyes. I had more to say, but we drifted apart shortly after because we were not taking the same morning classes.

I missed Theo during lunchtime, too. Instead, I ate with Foster, Trevor, and Trevor’s roommate whom I had met that day.

His name was Colin. He was a pretty cool guy, originally from the East Coast. Pretty sexy too— tall, with a buzzcut and huge biceps. My type.

He was on the water polo team.

The day was otherwise uneventful and the morning classes felt like they went on for hours and hours, but that might have been because I was counting the minutes until anatomy class in the afternoon.

I was curious, not only about what would happen with Theo potentially being a live-model, but also about seeing Mr. Gallan in another slightly too-small for his size outfit.

Just thinking about it, I popped a boner in my management class after lunch that did not subside until I finally walked into Anatomy 101 around 3 p.m.

As in the previous week, students who were on break prior to the class were in the classroom already, including Kyle and Theo, who were sitting together and horsing around.

Mr. Gallan was there too, setting up slides with diagrams and anatomy illustrations on the screen behind him. He was wearing his slutty black glasses and a tight white shirt.

He was also arching his back slightly as he looked up something on his computer.

That man’s ass was a perfect 10 and I was glad that my professor knew how to make his best asset pop.

Anyway, just like last time, I sat down next to Larry, behind Theo and Kyle.

“How was management?” Larry asked.

“Boring as usual.”

“Bet.”

“You were at break with the others?”

“We took our lunch quite late, but it was fun, we—”

Mr. Gallan started to talk and we shut up.

“Guys, is everyone here? Shall we start?”

I adjusted my pants a little; my dick would not go down.

About thirty students were seated, so Gallan began his class and I started wondering if I had been excited for nothing.

For the first ten minutes, the course was pretty dull.

“For the next few classes, we will focus on the abdominal and gluteal muscles, also known as the 'abs' and 'glutes' when you're working out with your buddies at the gym.” Gallan explained.

On cue, Kyle and Theo both lifted their sleeveless tank tops to show off their abs.

They could not help themselves!

A few other students looked at them, but the teacher did not seem to care. He kept going.

“The abdominal muscles are located in the trunk. Their primary functions include trunk movement, stability, and supporting the internal organs. The gluteal muscles are located in the buttocks. They are primarily responsible for hip extension, abduction, and rotation, as well as stabilizing the pelvis.”

“And we all know how we need a well-stabilized pelvis!” Kyle joked.

The professor ignored him.

“Both muscle groups are crucial components of the body's core; that's why we’ll study them first this semester. They work together to enable coordinated movement, maintain posture, and support the spine. Yes gentlemen, your glutes are connected to your abs! The dichotomy invented by gym rats between chest and leg day doesn't make much sense from an anatomical point of view."

To make his course more interesting, or simply to keep us from falling asleep, Gallan would often use gym lingo.

It worked with our group because most of the men in the room were obsessed with growing their muscles.

After all, we were in a sports college filled with dumb, shameless jocks.

I took notes without much enthusiasm until Gallan transitioned from theory to practice a few minutes later.

“Okay, so I asked if anyone wanted to volunteer to demonstrate how the core muscles work on a real human body, and I believe a few people offered their help.”

My interest was piqued immediately, and Theo sat up straight in his chair in front of me.

This was why I was there, for the live demonstration!

Mr. Gallan looked at his notes with the names of the volunteers. I imagined that Trevor and Kyle had signed up too.

He then looked up at the class as if he were picking the best model.

There was one obvious choice and I would have done the exact same.

“Theo? Would you mind joining me?”

Theo almost jumped out of his chair, too excited to be the center of attention.

“Of course! I'm happy to help the class!” Theo exclaimed.

A few guys chuckled.

“Okay, then come here. Stand next to me.”

The teacher usually stood on an elevated platform, and Theo joined him there.

Even fully dressed up, the pair looked amazing (though Theo was not wearing much to begin with), and I was immediately invested in the class.

“What should I do, sir? Show my abs?”

Theo lifted his tank top again, prompting more laughter in the room.

Gallan indulged him and smiled.

“Here we have a perfect example of very well-defined abdominal muscles, thank you Theo. But let's not jump ahead. First, turn to your side. I'd like to show the class something.”

“Yes, sir.”

Theo turned 90 degrees so that we could see his profile, at which point Gallan grabbed a pencil.

He began tracing Theo’s body with it, over his shorts and sleeveless top, starting from his large thighs and moving up to his lower back.

“See? This entire region is supported by the gluteal and abdominal muscles. Without them, our model could not even stand right. And as you can see from the side, this is not a straight line. The human body has curves to give us balance and mobility. Your buttocks serves an important purpose.”

He turned Theo to face the board and traced the pencil over his tank top on his lower back.

“These areas work together to provide a core structure that allows you to support your spine.”

The pencil continued tracing Theo’s waist and back until it reached his neck.

“Since our model has strong, large muscles, he has better support than someone who might be obese or doesn't have such well-trained muscles. Yet, being that muscular can also have some downsides. Can any of you identify them?”

A round of questions and answers began while Theo remained standing, either facing us or facing the other way.

At one point, and to answer one of Trevor’s questions, Gallan turned around as well and compared his own ass (frustratingly trapped in his tight black pants) to Theo's, showing that gluteal muscles can take different shapes according to various factors like age, genetics or training.

“All muscles serve the same purpose, but there are as many different muscles as there are human beings on this Earth.”

I had never been so attentive in class before.

But this was just the appetizer. 

And the best part was about to begin!

“Now, let's take a closer look at some defined muscles. We're fortunate to have a demonstration model in excellent condition today. Theo, would you mind taking off your tank top?”

He grinned widely.

“Sure, I can do that.”

Kyle cat-called him as Theo stripped down. Gallan was unperturbed; he did not seem to mind the students' reactions.

After all Theo was living for it, and it was well-spirited.

For the next part, Gallan dropped the pencil and directly used his fingers to show the class Theo’s abs.

He drew lines between each muscle, not shying away from complimenting his model.

“I have to say, Theo here has spectacular abdominal muscles. You would generally call it a six-pack, but actually, there are eight squares on his stomach. This is the treasure trail: a line of hair leading to the crotch and pubic area. It's prominent on Theo’s body but it’s present on almost every male specimen.”

Theo contracted his abs so hard to show them off that it was almost funny.

He then explained how he got in shape and the importance of diet and nutrition.

“Of course, nutrition—which is another one of your classes this year—is directly linked to the development of your anatomy. Should we move on to the glutes? May I ask you to strip down to your underwear, Theo?”

For the first time, there seemed to be a problem.

“Huh… Sir… I would but… I'm not wearing any.”

Absolutely no surprise there since we could already see the outline of his flaccid meaty cock through his blue shorts.

Mr. Gallan seemed taken aback, which was strange.

How did he not realize that Theo was going commando, with his cock bouncing so much in his short shorts!?

The whole class certainly knew.

“Oh, I suppose we can find another volunteer. There were a few more names…”

“Personally, I don't care. I’ve already shared a locker room with nearly half of these guys, so, if you don’t mind, sir, I can drop the shorts.” Theo avidly offered.

Gallan looked around.

Had he ever had a student so eager to get naked in the middle of his classroom?

His email did mention the possibility of full-frontal nudity, so we all knew it was a potential outcome.

Maybe he had not expected it to be so soon.

“Well, I certainly don't have an issue with it. We’re all adults, and this is purely academic. Although the study of genital organs was planned for later in the semester… That being said, I suppose that to study the glutes, being nude is much better anyway.”

“Your call, sir.” Theo said, already playing with the hem of his shorts.

Gallan scanned the room.

“There are only men in this class today, so I suppose it can't hurt. We’ve all seen everything just by looking in the mirror.” He smiled mischievously.

Before he could finish his sentence, Theo kicked off his shorts.

The guy was dying to expose himself!

As he stripped down to his sneakers, the students gasped.

I must admit, my jaw dropped as well.

It was one thing to catch a glimpse of the cock I lusted after so badly, but it was another thing entirely to have it displayed on stage in all its glory for thirty of our peers to admire.

Gallan moved aside to let everyone have a good extended look.

In all fairness, our teacher seemed as mesmerized as I was by what was surely the most beautiful uncut cock he had ever seen.

Even flaccid, it was bigger than my own cock when hard—a good six inches, if not more. The girth was equally impressive—like a freaking soda can.

The blue veins were visible even from where I sat, a few rows behind. The foreskin covered the cockhead, leaving a delicious bit of mystery, while the tip already looked a little wet.

I already knew that because of his condition, my roommate was practically leaking 24/7.

I also have to mention the balls. Massive, full, low-hanging, and so fucking hairy. They completed that cock perfectly.

Everything was extra-large sized on Theo—humongous and heavy.

I sort of understood why he was eager to flaunt it.

Hiding this work of art would be like spending hours at the gym building a perfect, chiseled chest and never being able to show it off.

“Bro, you're fucking massive!” Someone sitting in the front row eventually said, after a long moment where everything felt suspended in the air.

“Am I?” Theo replied with a smirk.

He moved his hips left and right, allowing his cock to dangle between his legs.

He knew exactly what he was doing and I was in awe.

His cockiness made him even sexier.

“Please, let's not comment on the model's attributes.” A flustered Gallan said after a while. “This… That is not the subject of this class.”

I distinctly saw him adjust the bulge in his pants.

He was as impressed as the others and certainly as aroused as I was.

Well, I was not sure if anyone could be more turned on than me, though, getting hard and literally leaking in my pants.

Thank goodness I was wearing jeans that day.

“I don't mind comments from my classmates.” Theo said, amused.

Weirdly, I was quite jealous that this show was being shared with the whole class.

Theo had never been so forward with me in the dorm and now I had to share his magnificent cock with everyone else, too.

Gallan was getting a little red.

“That's not the point. Yes, Theo's penis shows incredibly abnormal proportions but there’s no reason to judge or comment on it. At most, we can observe from a scientific standpoint that his penis and testicles are significantly larger than average. We'll discuss this in more detail when we study the genitalia and reproductive system.”

“You think my dick is too big, sir? It’s abnormal? Wouldn’t that be a good illustration for the class?”

Theo was pushing it so far.

There were mixed giggles and whispers in the room.

Foster, who was sitting in the second row on my left, seemed frozen in place. He was staring at the naked student in front of him. His eyes were bulging, his mouth was slightly open, and he was drooling a little.

Was I making the same face?

I became self-aware that Larry was next to me and might be gauging my reactions.

“Your penis is not too big, Theo. Listen to me— everyone— there’s no shame to be had when it comes to anatomy. There are no such things as too little, too tall, or too big. There are averages and statistics, but there have to be people on each end of the spectrum. Micro penises are every bit as valid as humongous ones, such as yours. We can only be grateful for what nature has given us.”

“So, what you’re saying is that I should be grateful for… What did you call it again? My humongous penis?”

He made it bounce again.

Gallan gulped.

I was losing my mind. I could not believe this was really happening.

“Yes, Theo. You… You can be grateful.”

“Do you all think there's a micro-penis in the room?" Kyle asked, joking.

Gallan felt like he was losing control of his class—and seemingly of his erection, which was becoming way too obvious in his tight pants. He walked behind his desk and cleared his throat.

“That’s enough. Gentlemen, we're here to talk about glutes. So, Theo, please turn around and show the class your buttocks.”

“You’re the boss, sir.”

Theo did not lose his cheeky smile as he turned around.

I could not take my eyes off the show for a second but I did briefly glance at the clock.

If Theo remained naked for much longer, he would soon have to show more than a flaccid penis.

He had obviously nutted right before walking to class, but even after only thirty minutes, he would often be struggling with his libido.

An unwanted erection became more and more likely as the class continued.

In any case, I feel it is important to state that Theo was as stunning from the back as he was from the front.

His ass was the definition of juicy.

It was fat but muscular, with two round and equally peachy cheeks, separated by the most tempting, hairiest crack ever.

The hair that grew along this path, from the lower back to his balls on the other side of his perineum, was darker than the rest of his body; a stark contrast to his pale skin.

I was eating up the view (sadly, failing to eat up the bare ass), as Gallan continued his teaching.

From then on, he used a green laser to point at specific areas on Theo’s body.

“The three main gluteal muscles are the gluteus maximus which is the largest, most superficial, the gluteus medius, and the gluteus minimus. These muscles originate on the pelvis and insert on the femur, playing a crucial role in walking, running, and standing upright. If Theo were to jump or stand on one foot, he would have to use all three muscles.”

Theo immediately illustrated this point by jumping twice and then keeping his balance while lifting one leg.

“We also use these muscles to fuck, I mean, to have sex. Right?” Kyle pointed out.

Clearly, he was frustrated by all the attention Theo was getting with his stunning body, so he felt the need to compensate by being outrageous with his interventions.

Gallan had retrieved his composure and answered the question impassively.

“You’re right, Kyle, if you thrust your pelvis to penetrate your partner, you’re using all three gluteal muscles.”

“Of course, I do!”

“In the case of our live-model, it's clear that Theo has developed strong muscles in his entire gluteal region. Depending on the practiced sport though, some parts of the glutes might be more or less developed. Theo has a surprisingly well-developed backside for a diver, which can certainly be explained by the years he spent practicing other sports—like gymnastics, perhaps. Is that what you did, Theo?”

“That's exactly what I did, sir. You're good!”

Gallan chuckled and adjusted his glasses.

I noticed a droplet of sweat sliding down his forehead.

“Thank you, Theo. Once you know the human anatomy, you can usually tell a lot about a person’s history from just looking at their naked body. Now, does anyone want to show the class where each muscle is situated on the body again? Who wants to come up here and show the class exactly where the muscles are on our model?”

I immediately raised my hand like a groupie at a concert.

I did not think it through; the teacher had just offered for someone to inspect Theo's butt, and my hand shot right up.

My body had talked for me.

“Oh, yes. Bastian. Come here. I’ll name a muscle we’ve studied today, and you’ll show the class where it is, using our willing model as a canvas.”

I stood up from my chair, feeling shaky, and hoped no one could see how badly I wanted to get closer to my roommate.

Also, was the precum stain on my underwear visible even through my jeans?

I tried to stop overthinking and act naturally.

“Good luck with the test, roomie.” Theo whispered to me.

Only then did I realize that it was still class, and I was supposed to know how to answer our teacher.

Gallan first questioned me generally about the functions of the core muscles we had gone through that day.

I may have used a few incorrect words, but that was not that difficult. It was the whole purpose of the class and I was not that dumb.

Things got much more interesting shortly after when he asked me to point to the exact area where all the muscles he listed were located.

We started with the glutes.

“Bastian, where is the gluteus maximus on our model?”

This was supposed to be an easy one because it covered basically the entire ass.

I pointed to the region he had shown earlier, but seeing that Gallan expected more, I ended up pushing my index finger against the exact point he had aimed at with his laser.

Believe me, I had been very focused on this part of the class and I knew what I was doing.

“But how far does that large muscle extend? Show us.”

I traced my finger all around Theo’s butt to show the entire muscle. This was surreal.

“Good job, Bastian. Now, where is the gluteus minimus?”

I did not move my finger away from his ass. Instead, I drew a line until I reached a firmer part, right next to the ass crack.

I felt some hair under my finger.

Fuck, I was so close to his pink asshole! If only I could spread his ass cheeks!

Theo had no particular reaction, but I could hear people chatting and laughing behind me.

I was also blushing profusely.

Who would have thought that the first butt I would ever touch in my life would be in the middle of class!?

Despite everything, I enjoyed every second.

“Okay. Let's move on to the abdominal muscles. Theo, would you turn around?”

Since I was practically kneeling to study his bare ass, when Theo turned around, his flopping dick slapped me in the face.

I was shook as I felt the flaccid cock hitting my left cheek!

“Wow, sorry, bro. I didn’t realize you were right there.”

This time, laughter exploded throughout the room.

Everyone had seen it!

“Guys, please. Be serious.” Gallan scolded the agitated class.

I was just speechless as the silence slowly came back.

"Bastian, would you show the class where the rectus abdominis is?"

I was startled, but I vaguely remembered that the rectus abdominis were basically the six-pack, or, when it came to Theo, the eight-pack.

I touched it.

Or caressed it?

What the hell was I doing? I could no longer think straight.

Bastian, get a grip! I thought to myself.

“That’s correct, Bastian. Now, can you point to the pyramidalis?”

“I… I'm not sure where it is.” I blurted out.

It was difficult to even hear what Gallan was talking about now, hypnotized as I was by the long and large dick hanging right before my eyes.

“Just trace it with your finger, search the muscle. I’ll tell you when you've got it. The rest of you sitting behind, help him.”

I moved my finger higher, and some students shouted:

“Nope, you’re getting away.”

I moved it lower.

“Yes, that’s better.”

I was breathing on Theo’s dick, and I could have sworn that it was starting to grow.

I looked up and saw that Theo was not so cocky anymore.

We both knew where this was going, and we needed the class to end soon, before he got an erection while I was inspecting the most sensitive area of his body!

“A little lower, Theo. The pyramidalis is a small muscle in the lower abdomen, below the rectus abdominis.”

“Here?”

“Just follow the treasure trail.” Gallan advised.

What was he playing at?

I was practically brushing Theo’s pubic hair at this point, getting close to the base of his cock. This was just crazy!

The smell from that area was making me dizzy too

“Better?” I asked.

“Yes, pretty much. You're in the zone.”

I was hot and flustered. I must have been sweating a lot.

“Bastian…help…” Theo muttered between his lips.

I was the only one close enough to hear him.

Shit.

His dick was growing even more. I was hiding it from the rest of the class, but Gallan, who was sitting next to us, could see it.

Why was he not stopping the exercise?!

“Okay, on to the next muscle…”

I saw Theo clench his fist, doing his best to control his rising erection.

Was it because I was on my knees in front of him that it was so hard for him to control himself?

I knew that the second I touched his cock, it would rise like a bouncy castle.

What I really wanted to do, though, was wrap my lips around the tip.

Damn.

“Bastian? Where is the Transversus Abdominis?” Gallan asked as if nothing was happening.

“I… I’m not sure.”

“Just explore, dude! Maybe it’s on his dick! You have to grab it!” One student said.

I think it was Kyle, but I am not sure.

“Boys, let's be respectful.” Gallan said.

“Hey, that was a legit suggestion. There’re muscles on the dick, right?”

“On the penis… And as I’ve told you before, the genitals will be studied later on this semester.”

“But we can't see anything, sir. Bastian’s blocking the view anyway!”

I had to block the freaking view!

Theo’s dick kept growing, and believe me, it was difficult to conceal. My body and face were the only things hiding his semi-hard cock from the entire class.

I looked at Gallan, begging him for help with my eyes.

For fuck's sake, the rising monster cock was about to hit my chin!

Finally, our teacher seemed to understand the seriousness of the situation.

“Well, I'm afraid the hour is almost up…” He stated suddenly. "Maybe we should continue the lesson next week. We have much more to learn about our core muscles anyway.”

“But, sir, at least show us the last one.” Larry asked.

“What was it again?” Another student intervened.

“Transversus Abdominis.”

“Yes, that one!”

I had never heard students so adamant to continue a class.

“Show us on Theo!”

I thought we were screwed. Surely, I would have to move and reveal what was truly happening in front of me, but Gallan saved the day.

He stood before the two of us and lifted his shirt, showing the class his own abs.

This move was so unexpected that, for a few seconds, no one cared about Theo hanging there naked. They all looked at their professor stripping and exposing himself.

With another dick-slap on my face as he turned around, Theo took the chance to quickly put his shorts back on.

A few seconds later, the bell rang, ending the class for good.

Phew!

Once again, it was a close call!
