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?

You volunteered to be the first guinea pig today, hm? Come up here then. (The other students chuckle.) Now, let's see... I want to know if we can make a man's penis larger. So, take off your pants and underwear.

Mmmh... quite impressive already! Alright, now lie down on the table. (To the other students) Everyone watch closely, this is how we'll be starting our lessons today!

Mmmm... I see you have quite the package there! Now, let's see if we can make it even more impressive. (To a female student in the back) Amelia, come here and help me. First, apply this gel to his penis, being careful not to get it on other areas.

Don't worry, this is all part of the lesson. I promise not to do anything inappropriate. Now, Amelia, help me get him nice and covered with that gel.

Mmmh...I see you're enjoying this already. That's a good sign! Just relax and let us take care of the rest. Amelia, continue to cover his penis with the gel. (To the students) As you can see from his reaction, it appears this method works quite well. Now we just need to wait for it to activate...

Don't worry, it should start to work soon and your penis will become noticeably larger. Just relax and enjoy the process!

(To the class) As I said, he's responding quite well to the treatment. It won't be long now until he experiences its full effects. Class, pay close attention and you'll all learn a lot from this demonstration.

Ah! You're getting excited already, aren't you? That's to be expected with this treatment. Just relax and let it happen. The full effect should be felt shortly... (To Amelia) Did the gel have any effect on his orgasmic response?

Fascinating! His erection is even stronger now, and it looks like he's about to cum again. Well, well...this is certainly an interesting observation for our class today. Everyone take note of this change in his reaction to the gel.

Excellent! Now we'll see if we can bring him back down again. (To a different male student) You, come over here and help me with this part of the demonstration. While I work on reversing the effects of the gel, you should focus on maintaining his erection.

Of course, I understand. There is another volunteer right here who'd be happy to help you out with that. (The other student blushes but agrees.) Excellent! Now we can continue the demonstration as planned.

Hmm... He seems to be responding quite well to your touch. That's interesting, I wonder if we can use that information in other contexts as well. As you continue, pay attention to how his body reacts and adjust accordingly. This is a valuable learning experience for all of us today!

Mmmm... I see you two are getting along quite well. That's another interesting observation for our class! Your kissing is certainly making this demonstration more enjoyable, both for us and for the student being tested. Please continue as long as you like, but remember to focus on what we're here to learn today.

I understand that you're enjoying the demonstration as well, which is excellent. Remember though, this class isn't just about pleasure; it's also about learning and discovering new things about human biology. Please keep both goals in mind while participating today!

I suppose it wouldn't hurt to demonstrate that information as well... very well then. opens mouth slightly My tongue is extended; feel free to touch or play with it while we continue with the demonstration. But remember, students, focus on the learning!

Ah! Well, isn't that an interesting result as well? Your cum tastes delicious! It seems like our little demonstration has turned out to be quite the sensual experience for everyone involved. Remember class, as you observe these reactions and experiences, think about what they might teach us about human biology and sexuality. Now, why don't we clean up a bit before continuing with the next part of our lesson?

In that case, I'm sure there are other interesting demonstrations we can do to further explore human biology and sexuality. Perhaps something involving the male ejaculate? Or maybe we could focus on female pleasure today? Let me think of a suitable activity...
