Josh can be a real dick.

The two teacher began their demonstration. Ms Mulligan laying on the mattress with her legs spread and Mr Wilder mounting her thrusting his bludgeon inside of her.

"You'll see that this is not a very technical position but it is a classic, so you should learn to do it right. " he explained.

Even with all her training and the fact she must be used to it, she was quickly blushing and clenching her fists as the massive dick was ramped into her.

After a few minutes she began to moan and scream of pleasure. Mr Wilder continued and shot his seed into her. As he rose up there was some dripping from his dick.

"It's your turn now. Because it will be your first time for many of you, cumming before she does won't fail you as long as you manage to get hard again and get the job done before the timer buzzes. " he said.

Before continuing Josh thought of something, most girls here were virgins and some of the boys had huge cocks .

There is no such thing as a hymen on virgin girls. The first time is not painful no matter the size of the penis.

the strength of an orgasm during sex is proportional to the size of the penis involved.

He taped enter proud to have avoided a disaster, the last thing he wanted was Kim in pain bleeding all over him on their first time together.

With all that happened before and the recent show, every pussy was wet and nearly every dick was hard. Even if it was not a lot Josh had the memory of having fucked before and used it to be better this time. (he had to take into account his huge cock though.)

The mattresses were put into positions and he ended facing Brian who was trying to make his micro penis hard to fuck Olivia.

Josh was ramming his large member into Kim who was already showing she enjoyed it. He also used the fact that she liked him and kissed her. The thought of what she did with her mouth was a bit off putting but she rinsed it with water between tests. He would have to make a rule to give cum no taste in the future. (giving it a good taste would have too many consequences.)

As he broke his long kiss he taunted Brian. "Hey Brian! You got a problem? Look it isn't that hard. You just put your dick in her and do like Mr Wilder showed us. Do you want me to come fuck her for you when Kim and I are finished? We should have a lot of time to spare."

"Maybe it's just that he isn't properly motivated. I don't know if you would be do good without those to put you in the mood. " said Kim massaging her tits. Olivia was so flat that muscular boys had a bigger chest than her.

She couldn't taunt her further because she was too busy having her mind blown by a massive orgasm. She had nearly passed out.

During the next minutes a few more moans of various intensities could be heard.

Kim and Josh were squatting around Brian and Olivia, with cum dripping from their genitals as they gave advice to the couple knowing full well that they had no chances to succeed.

Finally the buzzer came and most of the formerly popular boys had failed the test.

The teachers picked an item they couldn't wear and everyone was instructed to go take a shower before dressing.

There was a door in this classroom leading to the locker room. the not one like explained before there were not boys and girls segregation in this establishment. The lockers, showers, toilets were all co-ed.

Josh took his time helping Kim get clean and her tits were indeed very clean when he finished. The two dressed in their full uniform and looked as the others dressed.

Most uniforms were skimpier than theirs and a few students were missing one or two items. But there were also the bottom bunch where more skin was exposed than covered and a few students wearing only their shoes. Of course if their were their former selves they would flaunt their perfect bodies and turn this into a show. But the flat chested girls and nearly dickless boys were truly humiliated especially after failing sex ed in front of everyone.

Between the videos, demonstrations and tests, plus the shower and dressing sex ed lasted the whole morning. It was time for a lunch break before the rest of the classes.
