Dildo demonstration

Anna was very thankful that Mr. Jones released her out of the stirrups before he went to get the box with the last bit of lesson material. Finally, she could close her legs, and try to get her breathing to normalize a little.

Now that her senses were freed up a bit, nothing could shield her from the intensive aroma in the air. The smell of her own arousal. It was bound to be strong, as the teacher's desk was covered in her juices, thickly at some places, and she herself of course as well. All the students that were sitting in the half circle less than two meters away from her could smell it as well, and forever remember it. The open windows weren't doing much to mitigate it - they were probably even carrying the odours to students outside, or in other classrooms!

"One of these should be much more adequate to test out the dimensions of Anna's vagina", Mr. Jones said, putting the box down on the floor. It was still absolutely jarring how he was talking so casually about her intimates, and what was going to happen to them. How could he even keep his composure like that?

"But first, you all have to learn how to properly apply protection. Condoms are only one method, but one you don't want to miss. Anna already expertly applied one to the rubber facsimile she was using before. Now please organize yourselves in pairs, each pair grabbing one dildo and a condom."

This was the sex ed Anna was familiar with. Learning how to use condoms on rubber penises. Except that these students weren't embarrassed at handling them. They had seen so much more today already. Mr. Jones looked at their work, corrected where necessary, and praised jobs well done. He took the dildo that had the condom wrapped over it the most neatly, and glanced at his watch.

"Seven minutes till break... but I think, Anna, you've received enough stimulation to make it in time, right?"

She nodded weakly. It was true that it wouldn't take much more to bring her over the edge. But why had Mr. Jones said 'seven minutes 'till break' and not 'seven minutes 'till the next period'? ...probably not an important detail. Functionally the same, really.

Anyways, this was not the time for Anna to think about semantics. She was handed the dildo, and as she was assuming the position in which she was caught more than half an hour before, the sex ed teacher narrated what was going to happen now:

"More effective and satisfying than masturbation with a finger can be usage of a toy, like one of these dildos. It's also a demonstration for you of what vaginal sex could look like, at least vaginal sex with one inactive, but well-endowed partner with unlimited stamina. Anna will now proceed to masturbate herself to an orgasm using this dildo."

Anna had already lowered herself on the tip before Mr. Jones had stopped speaking, her horny sighs filling the room. Under the watchful eyes of the fascinated students, she was slowly shoving the rubber penis up her vagina, stretching herself, and groaning and moaning along the way. The lubrication couldn't be any better; she was making progress quicker than before. About three fourths down, she had to stop a little, to appreciate the ecstatic feeling of fullness. Somehow she was happy that she could finally let go; the situation truly couldn't get worse any longer, and indulging herself was even expected of her.

"Try to take as much in as possible, Anna. But don't hurt yourself."

She didn't need more encouragment than that. She slipped down further, getting filled up completely. Her bent knees had to shift position so she could lay them down on the desk surface. Her hands, too, had to touch down, to support her upper body.

Anna had the whole thing inside her now, up to the base. It seemed paradoxical, but she had never felt more comfortable in her life. For a moment, she could forget the circumstances, and just enjoy the moment.
