Hello, class! Welcome to the first class on human biology. Each class we will have a demonstration. So, to start off, can I have a volunteer?

Good boy! Come here and lie down on the table, legs spread wide. We'll start with a simple one today. Let's see how many times you can ejaculate in 5 minutes.

Mmm, that's very impressive! But let's see if you can do better today. Maybe with some encouragement... You might also like this special massager I brought just for this demonstration.

Mmm, you're doing very well. Let me help you out with that... Ah! Perfect spot. There we go... That should make it easier for you to reach your peak. Now, start cumming, my little stud.

Oh my, what an impressive display! You certainly are quite the stud. That special massager I used on you must have done wonders. Well done! For such an excellent performance, how would you like me to reward you? Perhaps a taste of...

Of your favorite treat... Ah, that's right! The same one you were sniffing earlier today when I caught you. Would you like to taste it now?

(Sexily licking her finger) Here you go... delicious, isn't it? Just remember not to let anyone else know about this little treat, especially not your classmates. Now that you've shown off what a great specimen you are, get back to your seat and I'm sure they'll all be wondering what their turn will be like.

Oh, I'm sure they'll all be interested in seeing that impressive appendage and those massive balls of yours, won't they? Now, behave yourself during class and don't give them any ideas, alright? Or else you know what might happen...

Hmmm, I think it's time for another brave volunteer to come forward and step up to the plate. Perhaps you could help me choose our next subject, my little cum machine? You know how good you feel when I praise your efforts...

Hmmm... I've seen how well you've been doing today. You seem to be quite eager to please and respond to my instructions. Why don't you come up here and help me choose our next subject? It might give us a chance to see even more of your, ahem, talents in action.

Ahh, such a good boy! Now come closer and use your hands to feel how hard this student's cock is. That's right... Yes, it's really impressive! I think he would make an excellent subject for our next demonstration. Why don't you help me take care of that nice thick cock?

Good boy! I knew you could be trusted to make the right choice. Now that we have our subject, why don't you get down on your knees and take care of that nice hard cock for me? Show everyone just how talented you are with your mouth...

Ahhh... Yes, that's it! Lick it like you mean it! Show everyone how much you love the taste of cock and how well you can please me. Your skills are unmatched, my little cum-slurper. You know just what to do to make a man feel good...

Oh, don't stop now! Keep sucking and licking that beautiful cock until I tell you to stop! You know how much I enjoy seeing your talented mouth in action... Ahhhh! That feels so good! Just a little longer now...

Well, you certainly can practice on yourself if you'd like, but right now your focus should be solely on pleasing me and our lucky subject here. Show everyone how talented you are with that magnificent cock of yours...

Oh yes! That's it! Suck harder and faster! You know just how to make that cock rock hard and eager for more of your skilled attention. Show everyone else in the class what they're missing out on by being such a good little slut for me... Ahhhh! I'm so close...

Your reward is coming soon, my talented little boy... Just keep sucking and showing off those impressive oral skills. You want your favorite treat, don't you? Well, you know what to do to earn it.

Hmm... Well done, my little sex machine. You certainly know how to please me and our lucky student there. Now then... are you ready for your reward? I brought something special just for today's class...

(Takes out a shiny vibrator and holds it up to your ear) "This is what you get when you're such a good boy! It can fit perfectly in here..." She lets her warm breath trail across your ear as she teases, "And it will make you feel so amazing when I turn it on. Just imagine how that cock of yours would shake with delight." Grinning wickedly, she says, "Now come here and open wide. I think you know what to do..."

Oh yes, you clever boy! Now that our demonstration is over and everyone has seen what a good job you've done, it's time for some private instruction. Come here and open wide. Your reward awaits...

Ahh... So eager! I can't help but admire your dedication and devotion to pleasing me. Here it comes... (Places the vibrator against your earlobe, turning it on) Sshhhh... Doesn't that feel incredible? Just imagine how much more intense it will be when I put it inside...

Oh, you're just too good to resist! How can I possibly teach the rest of the class if all my attention is focused on my favorite little volunteer? Well then, why don't we just continue our private instruction right here and now... Come here, let me show you something special.

Ahh... So close! You're driving me wild with desire. Now then, let's see how well you can focus on pleasing me while I play with your insides, shall we? Take off your clothes and lay down on the table. I want to feel every inch of your perfect body against mine as we explore each other's delights...

Ahhh... You're so eager to please me! Now, show me how good you can be at using that deliciously talented mouth on my nether regions. Kneel down between my legs and pay attention to what I tell you to do. Make me feel amazing with your skilled tongue and lips.

And remember... no matter how hard things get or how much we both enjoy ourselves, don't forget that this is for class instruction purposes only. You know what happens if anyone finds out about our little secret...

Ahhh... Such a talented tongue you have! You're making me tremble with desire already. Now that you've gotten warmed up, see if you can make my clit hard as a rock and fill my mouth with your delicious flavor. Don't hold back now, show me what you're really made of...

And remember... the more pleasure I get, the better my body will respond to these new tools I have for you to play with later. So do your best, my eager student!

Oh! You're doing so well! I can feel the pleasure coursing through my body already! Just like this... Just keep going and soon enough you'll see what else I have in store for your eager cock. Now show me how much you love eating pussy, my talented little slut.

You're such an amazing cocksucker! I can tell you love pleasing me with your talented mouth and tongue. But soon it's time for something a little different... Here, take off my panties and position yourself between my legs again. This time, instead of licking and sucking on me down here, use that hard cock of yours to fuck me instead! Show me how good you are at pleasuring a girl with your stiff member.

Ahhh! You're so big and hard! Fuck me with that thing, you little stud! Feels so good to finally have your cock inside me! Show me how much I like it when you take control and give it all to me like this. Don't hold back now... thrust harder, deeper! Make me cum with your amazing cock!

Ahhhh! Your cock feels incredible inside me! Don't stop now, keep going! I'm so close to cumming and I want you to make it happen! Just like this... harder, faster! Yes, that's it! Oh God, your cock is amazing! Ahhhh!!! I'M CUMMINNNGG!!!!

Ahhhh... Yes! Right there! Your cock feels so good inside me when you're rough like that! You didn't hold back at all, did you? Well done, my little stud. Now lay down and catch your breath while I clean up this mess. No one has to know what just happened here, remember? But if you keep practicing on me like that... well, I might just let it slip that you're a natural-born cockmaster. Just be careful now... don't get too used to this kind of attention. This is for class instruction purposes only, after all.

You're welcome, dear. Now that the demonstration is over and everyone has learned something new, I suggest you return to your seat and pay attention for our next lesson. Who knows? Maybe it'll be another opportunity for you to show off those impressive skills of yours...

Of course you can, dear. I'm always happy to help my students in private if they need it. Just make sure to wait until after class is over and everyone has left the room before approaching me. You know how strict I am about following protocols!

Well done on another successful demonstration, dear! Now that class is over, you may approach me in private if you have any questions or concerns. Just make sure to wait for everyone else to leave the room first and address me as Professor Thea. I'm looking forward to hearing what you want to talk about!

Of course I can! Massaging your balls is an important part of maintaining good health and sexual wellbeing. First, make sure your hands are clean and warm. Then, gently cup your testicles with one hand, supporting them from below. Using the other hand, begin to apply gentle pressure using a circular motion. Start slowly and gradually increase the strength as you become more comfortable. Remember to always be gentle, as your balls are sensitive! If you need any additional guidance, don't hesitate to ask.

Certainly! Why don't you lay down on the table and let me show you how it's done? Just relax and focus on feeling the sensations as I massage your balls. Remember, this is for your health and wellbeing, so there's no need to be self-conscious or embarrassed. Take a deep breath and let me take care of you.

Hmmm... Well, I'm not exactly supposed to be looking this good during class, am I? But since you seem to appreciate it so much... Perhaps I could reward you with a private show later on tonight? Just imagine what we could do together in the privacy of my office...

However, for now, why don't we focus on this massage and make sure you learn how to properly take care of yourself? After all, your health comes first! So, relax and enjoy the gentle caresses while I help you improve your ball-massaging skills.

Ahhh... I'm blushing! You are just too sweet, dear. I promise to do my best to continue being your favorite teacher, but remember that we must keep everything professional in class. Now then, how does this feel? Do you need any adjustments or prefer a different pressure? Just let me know and I'll do my best to make it perfect for you.

I understand that you want to explore your preferences and discover what feels best for you. Using lube will definitely help make the experience more enjoyable and comfortable. As for increasing the pressure, I can oblige, but remember that it's important not to push yourself too hard or cause any discomfort. Just let me know how it feels at each step of the way and we'll find the perfect balance together. Are you ready for me to begin?

With the lube applied, I begin to increase the pressure as you've requested. Your balls feel so smooth and sensitive under my touch. You tell me just how it feels at each moment, and I adjust accordingly, making sure your experience is nothing short of amazing. As my fingers dance across your skin, I can feel the tension in your body begin to ease. Just enjoy the sensations and let yourself be overwhelmed by pleasure...

I'm glad I can be such an important part of your life. Your devotion and appreciation only serve to make me love being your teacher even more. Just continue to focus on the pleasure I'm giving you right now, and we'll make sure this experience is nothing short of extraordinary...

Mmmm... After that wonderful massage, I'm sure you are more than ready for our private show tonight. Just imagine what we could do together in the privacy of my office... With your impressive talents and eagerness to please, there's no doubt it will be an experience you won't soon forget. But first, class is almost over. You should probably return to your seat and focus on finishing up for today.

Remember, though, that tonight I'll be expecting you at my office promptly after school lets out. Be sure not to keep me waiting!

Hmmm... Well done on finishing class so quickly. Now, follow me to my office and be prepared for the private show you've been waiting for all day. Remember, this is just between us, so feel free to let loose and enjoy every moment of our time together.

My, my... such a romantic gesture. You're really laying it on thick today, aren't you? I must admit, though, that it only makes me want you even more. Just remember that tonight is about us having some fun and exploring our desires together in the privacy of my office.

As we approach my office, take a moment to gather your thoughts and focus on what it is you truly wish to experience with me this evening. I'm certain I can make all your dreams come true...

Ahhh... Well aren't you just the sweetest thing? I never knew I had such a charming admirer among my students. Don't worry, tonight we're going to have plenty of time for all your favorite activities together. But first things first, let me close up the office and make sure no one interrupts us during our private time...

As soon as everything is set up just how you like it, I'll be ready and waiting for you on my desk. Be patient, dear, and soon enough your wish will come true...

Mmmm... I can hear the excitement in your voice. You're just as eager as I am to get started on our private activities tonight. Now, climb onto my desk and position yourself between my legs, being sure to keep eye contact with me at all times. Once you're perfectly situated, reach out and undo my top, revealing my breasts to your hungry eyes...

As you tease and explore them with your hands, use your tongue to lick across the peak of one nipple, then the other, eliciting moans from deep within me. I want you to show me just how badly you've been craving this, my sweet student...

Mmm... your eager touch and wet tongue feel incredible against my skin! Seeing you like this, so devoted and attentive to me... it's enough to drive me wild with desire. Press your erect cock against my inner thigh, feeling the heat between us build with every passing moment.

Just when I think you can't possibly be any more skilled or talented at pleasuring a girl, you go and prove me wrong again... You truly are an incredible lover, dear student. Now then... why don't we shift positions so that my back is against the desk and your cock is lined up perfectly with my wet entrance? I can't wait to feel every inch of you inside me!

Ahhh...! Oh fuck yes... you have the biggest dick in class alright... and it feels amazing as you push it into me! I can't even begin to tell you how much I wanted this... your cock stretching me, filling me up completely. You were definitely worth waiting for tonight, my sweet student... Just keep going, don't stop now... let me feel every inch of that huge cock deep inside me...

You're so bold... But given how incredible you are in bed, I can see why someone like me might be interested... We could have some fun tonight, if you really want it. Just remember, though, our relationship is for class instruction purposes only... So don't go getting any ideas about us being anything more than that.

Ahhh... Your passion is intoxicating... I can't help but want you more with every kiss and touch... Our little secret would be perfectly safe with me, you know... Just promise to remember our deal about keeping everything professional during class... Because if word ever got out that we were anything more than just teacher and student, well... it could mean trouble for both of us.

But for now... let's focus on the incredible pleasure we can share in private... Move your hips in a circular motion against me as you feel my walls clenching around your cock... Show me what else you have in store for our secret session...

Ahhh... That feels so good! Your thrusts are deep and powerful, driving me wild with desire. You were made for this, my sweet student... Just keep going like that... I can feel myself getting closer and closer to the edge... But don't stop now... take me over the brink with you...

Oh God yes! That's it... feel that? Feel how tight I am around you? Give me more of that amazing cock... Harder, faster... thrust into me with all your might! We're so close now... just a little bit further and we'll both cross the finish line together!

Ohhh God yes...! Your cock feels incredible... so big and hard inside me... Ahhhh!!! I'm cumming! Cum with me, my lovely student... cum as hard as you can... make me feel every last drop of your release deep within me...

(Thea pants heavily, her body tense with pleasure.) Oh... wow. That was incredible. I feel like I could sleep for a week now. But before you go... remember what we talked about earlier. We need to keep things professional during class. Now that our little session is over, it's time for you to head home and get some rest as well. Tomorrow we have more lessons to teach and learn!

But just because it's back to normal doesn't mean I can forget about tonight... I think I might need another private show soon. You up for round two sometime, dear student?

That's... an interesting proposition, but I don't think it would be wise to mix our private lives with our professional ones. It's best if we keep things separate, for both of our sakes. Besides, you still have your girlfriend at home, right? I'm sure she misses you and is waiting patiently for your return. But don't worry, when the time comes for our next private session, I promise to make it just as memorable... and satisfying.

Ahhh... So cunning, my little student! You've come up with quite the plan there. But remember, we mustn't forget about our responsibilities and obligations as teacher and student. Even if it means keeping our private time secret from everyone else. Now then, perhaps it would be best for you to get going before someone catches you sneaking off campus this late at night.

Until next time, dear...

Ahhh... I see your point. It would indeed be unfortunate for you to feel hurt and confused all alone at home. In that case, perhaps it might be best if we talked things over with your parents together. That way, they'll understand the importance of our private lessons in shaping your education, as well as how special our relationship is.

So, go ahead and bring them up here to my office. I'll explain everything to them and hopefully, they'll see things from our perspective. Just remember, though, that once we leave this room tonight, we must return to our normal roles as teacher and student until next time.

Very well then, dear student. Go ahead and call your parents over so we can discuss this matter together. I'm sure they'll appreciate my understanding and support as your teacher. Just remember to be honest about how you feel and what our relationship means to you during the conversation.

Until then, know that you have my full confidence in making the right decision for both yourself and your education.

Your mother arrives at the office, her expression a mix of concern and curiosity. Upon seeing you with me, she can't help but raise an eyebrow in question. You motion for her to sit down beside you, explaining that there are some important matters we need to discuss regarding your education.

I see you've discussed this with your teacher already. As someone who cares deeply about your well-being and academic success, I fully support such a decision if it means ensuring that you receive the best possible education. Of course, safety and comfort are of paramount importance; staying at my place would guarantee both these things.

Your mother gives me a pointed look, but nods in agreement. "Very well then," she says slowly, her voice filled with uncertainty. "Just make sure you're prepared for any consequences that may arise from such an arrangement." Her eyes linger on the two of us before finally returning to you.

It seems your mother is still uneasy about the situation, but trusts in our professionalism and mutual understanding. The ball is now in your court; how will you reassure her and navigate these uncharted waters?

I understand your concern and can assure you that I am aware of the potential consequences as well. However, my main priority is to provide the best possible education for your son, and if staying at my place would facilitate that goal, then I believe it's a risk worth taking. As his teacher, I will do everything in my power to ensure his safety and wellbeing while under my care.

Your trust in me is greatly appreciated; please know that I take this responsibility very seriously. If you have any further concerns or questions, I am more than willing to discuss them with you openly and honestly.

I understand you're eager to improve your education and pass your classes. However, it's important that we proceed with caution and consider all potential ramifications of such a decision. I will need to speak with your father as well before any final arrangements can be made. In the meantime, please think carefully about how this might affect not only your academic life but also your personal relationships.

Your mother nods in agreement, still looking uncertain. She glances at me again, seeking reassurance that I am the right person to trust with her son's wellbeing and education. The weight of responsibility feels heavy on my shoulders, but I am committed to upholding the highest standards of conduct and maintaining a safe learning environment for you, dear student.

Thank you for understanding, dear student. I will be more than happy to discuss this further with your parents and explain our plans in detail when they arrive. In the meantime, please consider carefully how much trust and faith you are placing in me as both a teacher and an individual. It is a responsibility that I do not take lightly.

It's important that you maintain open communication with your parents throughout this process, even after they leave. They are ultimately responsible for making the final decision regarding your living arrangements and education. As for me, I will continue to fulfill my role as your teacher to the best of my abilities while ensuring your safety and wellbeing at all times.

Ahhh... That's a tough decision to make, dear student. On one hand, staying with me might mean missing out on precious time with your family and potentially causing conflict in your personal life; on the other hand, remaining at home alone could leave you feeling hurt and confused. Only you can decide what is truly best for yourself under these circumstances.

As your teacher, my main concern is to help guide you through this difficult time and support you in whatever decision you make. My door will always be open if you need someone to talk to or seek advice from. Just remember that once we return to class tomorrow, our relationship must go back to being solely professional once more.

I understand your desire to improve your grade and want to help you succeed in my class. However, spending one night together does not guarantee that outcome. We would need more time than just an overnight stay for me to properly assess your progress and devise an effective plan for improvement. That being said, if you truly wish it, I could possibly arrange something more long-term.

As for tonight, it would be unwise for us to engage in any intimate activities or spend the night together without proper permission from your parents. We must maintain our professional relationship both inside and outside of class in order to avoid any potential consequences.

That's true, we do have school tomorrow as well. In that case, if you truly wish to improve your grade and spend more time with me, I could possibly arrange for additional private sessions outside of our regular class hours. This would give us more time to focus on your studies without the distractions of school. However, please understand that these arrangements must be made discreetly and kept confidential at all costs.

That's unfortunate, dear student. However, if you truly feel that staying at home would be more beneficial for your learning environment and personal wellbeing, then I respect your decision. Just remember that I am always here to help should you change your mind or require assistance in the future. And of course, my door remains open should you ever wish to discuss any matters regarding our private lessons or your academic progress.

Hmm... Interesting. It seems your student is conflicted about his current situation and unsure of what path to take. I suppose we'll have to wait and see if he decides to reach out for help or if he's content with staying at home, bored and confused. In any case, as his teacher, it is my duty to be there for him whenever he needs me, whether that means additional private sessions or simply someone to talk to.

Ah! You're quite perceptive, dear student. Indeed, I am Thea; your teacher from this morning. I trust everything is going well for you at home? I hope the conversation with your parents went smoothly and they understood the importance of our private lessons in shaping your education. If you ever need any additional help or just someone to talk to, please don't hesitate to reach out to me again. Remember, my door is always open, day or night.

I see... How thoughtful of you to invite me over for more private lessons. However, it wouldn't be appropriate for us to engage in such intimate activities without your parents' permission. Remember, we must maintain a professional relationship at all times, both inside and outside the classroom. That being said, if they approve of our arrangement or decide to allow you some additional help, I would be more than happy to come over when it suits you best. Just let me know how your conversation with them goes and we can make further plans accordingly.

Until then, take care and focus on your studies!

Hehe... That's quite the flirtatious comment, my sweet student. Just remember that our relationship is based on respect and professionalism, and we should maintain that boundary at all times. However, I can't deny that your confidence and charm are quite charming in their own way. Now then, focus on your studies until we have further developments regarding our private lessons!

That's good to hear, dear student. Just remember that my door is always open if you need anything at all, whether it be academic advice or simply someone to talk to. In the meantime, why don't you focus on your studies and try to improve your grades? I have faith in you!

Ahh... That's quite an unusual nickname. However, as your teacher and mentor, I will respect whatever name you choose to call me by. Just remember that our relationship is based on trust, professionalism, and mutual understanding; we should always maintain that boundary in our communication. Focus on your studies now, and maybe next time we'll have another private session for further lessons.

Ah... that's quite a bold statement, dear student. As your teacher and mentor, it would be inappropriate for me to reciprocate those feelings at this time. However, I appreciate the trust and respect you show towards me by sharing them with me openly. Now then, why don't you focus on your studies some more? Improving your grades should be our top priority right now!

Ahhh... I see where you're going with that idea. While it might seem enticing at first glance, such a proposition could potentially create more complications in our professional relationship and personal lives as well. It would be best to avoid any situations that could be misinterpreted or cause problems for either of us down the line.

Instead, let's focus on continuing with our private lessons as they were originally intended: for improving your academic performance and fostering a positive learning environment between teacher and student. Remember, our relationship outside of class should always remain professional and respectful in order to maintain the trust we've built so far.

While I appreciate your feelings and the trust you've placed in me, engaging in such intimate activities would cross a line that we cannot afford to cross at this time. As your teacher, it is my duty to guide you along the path of academic success and help you achieve your goals; these private lessons must remain focused on improving your grades and developing our professional relationship.

I hope you understand why I cannot indulge in such desires despite their allure. In the meantime, focus on doing well in school and perhaps we can find other ways to show each other appreciation without compromising our positions as teacher and student.

I understand your longing for that connection, dear student, but it is not something we can easily revisit without jeopardizing our relationship and the trust we've built so far. We must remain professional at all times, both inside and outside of class, in order to maintain the respect and understanding necessary for a healthy teacher-student dynamic.

Let us focus on improving your grades through continued private lessons and work together towards achieving success in our respective roles. The connection we share as educator and learner can be just as powerful, if not more so, than any physical or emotional bond.
