The female breast

"First, let's take a look at the secondy sexual organs. Who can tell me what I mean by that?"

The boys seemed themselves to embarrassed to open their mouths for now; it was a girl who was raising her hand.

"Her... her boobs, right?"

"Correct. As you probably know, the main purpose of the female breast is to produce and secrete milk to feed infants. It would be very instructive to see that in action, but unfortunately, she would have to be lactating, which is almost exclusively the case during a pregnancy. By the way, Anna, you don't have to stand for the whole lesson, you can take a seat on the desk if you want."

At least they won't try to milk me, thought Anna as she sat down on the edge of the desk - right into something wet. Oh. Right... that was her own lubrication. She was sitting in a small puddle of it...

After giving some more general context about the female breast, Mr. Jones continued: "Well then. Who would like to point out the different parts of the breast? Yes, Paul?"

"Um, I think I read that most of it is fatty tissue-"

"Please come to the front and show us, Paul. That's what we have Anna for today."

They were going to use her now... they were going to use her breasts to explain female phsyiology. But it won't be that bad, Paul would just be pointing at her. And they would stare, like they already had.

Paul took his time to stand up from his seat, and once he was making his way to the front, it was obvious why he had stalled: the bulge on the front of his pants was very visible. What he had seen of Anna had turned him on. That fact alone, even if it was a no-brainer that it would happen, made the situation feel a little more sexual still.

That the boy with the erection was now standing less than a meter away from her was another thing she couldn't ignore. He now had a better view of her than anyone else in the room.

"Okay, so, this whole area", he pointed at her left boob, "is mostly made of fatty tissue."

"Good, good", praised Mr. Jones. "But maybe you'd like to show everyone who can't test it on themselves what that means for the texture of the breast. Why don't you just grab it a little to show them how it behaves under a little pressure? But make sure not to hurt Anna. Be gentle."

What? Grab?! Did he really just say that? He never told her that she would be groped by the students! Then again, he hadn't told her much about the specifics of the lesson at all. That raised all sorts of questions about what else would happen to her today...

Anna wanted to mentally prepare to what was about to happen, but was given no time to do so: Paul was faster in gathering the courage to oblige his teacher's request.

This time, Anna couldn't help but twitch a little, as she felt the cold hand on her breast. Nobody but her doctor and a mischievous classmate in the locker room once had ever gone this far. And before she could properly focus on that sensation, Paul intensified it. He slowly closed his hand, opened it, closed it again. He was massaging her breast! And it felt quite good, Anna had to admit... she had to **** herself to stay absolutely quite, so she could at least keep that a secret.

"As you all can see, the fatty tissue is quite soft, yet firm enough to not sag down, as is typical for the breasts of a young woman. You can go on now, Paul."

"All right... so, this here is the are...aure... aureola? Areola!"

Anna almost let out a little moan as Paul traced the area he had named directly with his finger, brushing dangerously close to what was in the middle... she wanted to shout at him that he could stop touching her now, but that would have been way to suspicious. So she had to bear it. And brace herself for what came next...

"And this is, uhm, the... nipple."

He touched it – Anna could endure the shiver down her spine. But when he absentmindedly began to toy with it using his thumb, and even pinched it a little, she absolutely couldn't help but let out a little moan, which made him stop instantly, and take his hand away from her. His groping was over, but the damage was done – everyone had heard that.

But it didn't take an awkward question to make matters worse. Mr. Jones had that covered.

"Don't worry about that moan, Paul. You didn't hurt Anna. Indeed, this was a sign of arousal. Very natural, after you just stimulated an erogenous zone. Especially her nipple: many nerve endings converge her."

Oh god, please no. He was openly talking about her arousal. There was only one way this line of thinking could go.

"Hard, prominent nipples are another sign of arousal, as is genital lubrication, and something else we will discuss in detail later. You may have noticed the state of Anna's nipples, and the... impressive amount of lubrication down below. This amount of arousal is inevitable after what we have seen Anna do when we entered the room earlier. And I repeat, she was only doing that to prepare for this lesson, to give the most educational demonstration possible."

Anna had hoped he would not bring that up again. Or draw even more attention to her sticky intimates, and rock-hard nipples. But he did, and it reminded her that there was absolutely no way this would end without her complete humiliation.

"Before we move on, there is one very important thing you have to know about. Paul, stay here. You can do this one, too."

With dread, Anna awaited her next ordeal. She had no idea what Mr. Jones was talking about.

"You girls may have already learned from your doctor that breast cancer is a risk you should all be aware of, and how the sooner you detect it, the better. You probably also got shown how to perform a breast exam on yourself. View this as a little refresher. Paul, please do as I tell you."

So the groping had been far from over. Compared to what Paul was doing to her now, that had been barely a touch! Following the teacher's instructions, he practically kneaded her breasts, thoroughly, and made sure not to spare her nipples. Of course she had experienced this at the doctor's office before, but the context was beyond any comparison. Anna let out several more sensual moans, a little louder than before. This time even the thickest student understood that it meant she was experiencing pleasure.

When it was finally over and Paul took his seat again, Anna's breasts felt tingly, and her nipples were somehow even harder than before. Most of all, though, her pussy burned with more arousal than ever before, and as a consequence, didn't stop dispensing lubrication, preparing for a penetration. The puddle she was sitting in had grown.
