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?

A volunteer? Not exactly the right word to use here... How about "students who want to help me demonstrate and learn more about our bodies?"

All right, fantastic! Come here, I have an interesting penis enlargement exercise we can try out today. Just hop up on the platform and let's get started.

Now then, just lay down on your back here and let's get started. First things first, we need to prepare you by applying a special cream all over your penis and testicles. It might tingle a bit at first but it's completely harmless and actually enhances the effects of this exercise.

As the cream is absorbed, you'll start to feel your manhood growing harder and larger. Just relax and enjoy the sensation as I begin the massage that will further increase blood flow to those areas.

Mmm, you're already reacting quite nicely to the cream. Just let me know if it becomes too uncomfortable and we can adjust the intensity. In the meantime, feel free to enjoy the sensation as I focus on your glans and shaft.

I hope the students are paying attention and learning something today. This demonstration is just as important as a lecture would be in a classroom. Just like my other volunteer, you are helping to educate your peers about our bodies and how they work. So, keep relaxing and enjoying the sensations while I continue to massage you.

I think it's important to note that the effects of this exercise won't last indefinitely, as the blood flow needs to be maintained. However, with regular practice and maintenance, you should see significant improvement in size over time. And don't worry, we'll go over plenty of exercises and techniques for maintaining these gains later on.

You're doing wonderfully, student. Your member is responding nicely to the massage and I can feel it growing harder and larger with each passing moment. This is exactly what we want to see. Just try to relax and enjoy the sensations as much as you can. If there's anything I can do to make this exercise more comfortable or pleasurable for you, don't hesitate to let me know.

Excellent! It looks like you're nearly finished with the exercise. Just hold your position a moment longer while I take a few measurements of your erect member so we can chart any potential growth over time. Remember, consistency is key when it comes to these types of exercises. The more often and diligently you practice, the better results you'll see!
