That was only the first period

It took Anna a few minutes to come to her senses again, remaning rather disoriented. With sluggish movements she sat up on her pillows, and surveyed the scene to get a sense of the situation again.

The classroom was currently empty, save for Mr. Jones, who seemed to be reading something on a tablet computer he held in his hands, as the teacher's desk was currently occupied by Anna. She looked down at it. The stirrups were still fixed to the edge, and the camera with the display was lying to the side. The surface was a sticky mess, even though the juices had begun to dry. It was the same with her thighs, while her pussy was still very much moist.

The context was slowly coming back to her, and with her constant, immense arousal resolved for the moment, there was nothing distracting Anna from the magnitude of the things that she experienced in the last 45 minutes.

Naked and dripping before the class. Stared at. Fondled. Her most intimate parts examined and explained in detail, and touched while she moaned with pleasure. Fingered. Discussions about her arousal. Questions about very intimate topics. And, finally... fucked with a dildo to a thunderous orgasm.

All of this, in front a sex ed class, and in part done by students of that class. They had seen everything of her.

Anna tried to steady her breathing. It was over now, right? And nobody had taken pictures. At worst, there would be rumors. Suddenly feeling a little cold, she drew her legs against her body and curled up into a ball. She needed cover.

"...so, Mr. Jones? We're done now, right? I can get my clothes and... get dressed again?"

For a moment, it seemed as if he was ignoring her, then his head suddenly snapped in her direction.

"What? Done? No, why would we? It's not the time to get dressed, that would just waste time."

"But... huh? The lesson is over. Why would I not...?"

"It's just the break. The second period starts in a few minutes, and everyone will be back on time, I hope. Then we can finish up the remaining activities."

Bewildered, the girl just stared at him. With every second, her eyes seemed to be going wider, and her jaw was nearing the ground. "S...S-second p-p-period...?", she stammered. Was this real? Or some orgasm-induced hallucination?

"Yes. This was always going to be a double lesson. Has to be, with how rare it is to get a naked model. Lesson plan says to make the most out of the situation, and since it will be suspicious if I make an exception for you... Just focus on the positives. Like, not being expelled."

"I-I just got done getting screwed with a dildo! Having an orgasm in front of... everyone..."

"Oh, don't worry, you won't have to resume action immediately. You will get an additional ten minutes of downtime, if you need it. There isn't that much left to do..." He was scrolling through some kind of check-list on the tablet.

Did he really not understand what she was incredulous about? For one, she couldn't possibly imagine what was still left to do. Unless he demanded repeat performances of her. That would be more than humiliating enough.

"...what... what will that second lesson include, exactly?"

"Sorry. I would tell you, but the model isn't supposed to know the plan beforehand, so that the reactions of her body are genuine."

What kind of stupid rule was that? What difference did that make for sexual education? There was a lot that Anna didn't understand about this, but she was too tired too argue. And now too nervous, too. Her ordeal wasn't over after all. She would be seen more, and there was more humiliation to come, she was sure of it.

Her attempts to relax on the pillows were ineffective. Without her arousal, Anna was hyper-aware of her nudity, and the stickyness, and the lewd smell. At least the residual tingling in her nether regions seized, the echoes of her orgasm finally coming to an end.

After the bell rang again, it took more than five minutes for the students to find their way into the room again. No doubt many of them had ran off to the toilet to take care of some personal business. How she envied them for their privacy.

Confronted with the ogling eyes again, her body being no less interesting than before, Anna had to suppress the urge to cover up. She knew that the lesson was about to resume, and with that her humiliation. But there was something even worse. In anticipation of this, she felt her body react. Her nipples remained hard, her pussy heated up again. In spite of everything, she was going back to being aroused, and couldn't do anything against it.
