Taylor, One of the flat chested girls

"Alright everyone by descending order of grade will now choose a partner for the next part. Remember you cannot refuse more than two offers and the last two will be paired no matter who they are." Said Mr Wilder.

Josh walked in front of the class to make his pick. He could have anyone in the room. He could have changed the rules to get his teacher or his sister. But he really wanted to fuck one of the previously popular girls, Taylor.

"Taylor will be my partner."

A once very well endowed woman, Taylor's breasts were reduced to the size of teabags after the rule change. Serves her right for spending most of class with her eyes glued to her cell phone instead of paying attention to the lesson.

Taylor's face lit up while the rest of the classroom was in shock. The biggest dick was being paired off with one of the smallest pair of boobs. While the two brightest minds of High-school + don't always pair up, it was almost unheard of for someone so big to go for someone so small.

Kim's eyes shot daggers at Josh. "This better not be a regular thing for you. I'd make a better partner and you know it."

All the other students paired up. His sister ended with Fred, a fellow nerd from high school who always had a crush on her and Kim ended up with Derek, the boy with the second largest dick in High-school +.

The formerly popular ended grouped together. People had to be careful that their twin and themselves wouldn't be the last two remaining. Brian and Monica were the last two to pick someone and ended paired with Olivia and Jeremy an other pair of footballer cheerleader siblings.

The two teachers then removed their bathrobes to reveal their perfect bodies and the massive member between Mr Wilder's legs.

"We will now demonstrate the two things you will be graded on later so look closely and take notes if you need to. But first, everyone naked! You will make a chair circle around us with a chair for each team. Once naked the boy will sit on the chair and the girl on his lap. You should get used to this because the bathrooms, restrooms and locker rooms are co-ed at High-school +. " said Ms Mulligan.

Josh undressed without complex knowing that he would have nothing to be ashamed of and sat down in the chair.

Taylor easily removed her bottoms, but hesitated to take off her top. Josh completely forgot that she would be embarrassed by her lack of tits and decided to help her take it off.

Her nipples bounced ever so slightly when Josh released them from her shirt. He tried to make her feel a bit more comfortable by pulling her in and sucking on her perky nipples.

She moaned and Josh's massive cock sprang up and became rock hard. It made sitting down a little awkward since Taylor was so inexperienced with large cocks.

Other were not that lucky as their dicks were so small they either couldn't get erect or didn't reach the girls even with them sitting on their lap. And they had nothing to grab on their partners.

The test would be rather simple. The girls would be graded on the quality of the blowjob they would give their partners. The boys would be graded on their ability to fuck their partners to an orgasm.

Ms Mulligan dropped on her knees and began to give Mr Wilder a very sensual blowjob. She had to use both hands to hold his shaft while she kissed the head. She then began licking the whole length of it while gently playing with his balls.

Finally she put the end of it in her mouth while stroking it slowly. Then doing something that seemed barely feasible given the size of it she proceeded to deep throat him, swallowing the whole length of it and making him fuck her mouth balls deep.

Mr Wilder twitched and after carefully extracting his dick from her throat she locked the last drops of cum from it.

"This was the test for girls. You don't have to deep throat your partner for a passing grade but what I showed you was what you have to do to get a perfect grade. " she explained. Josh had an inkling that Kim with her competitive nature would aim for just that.

" We will now test you on that to let me some time to recover before the next demonstration. " said Mr Wilder.
