Knees from behind

Megan's blows were expertly devastating but Mr. Phillips was used to punishment and had received only 2 kicks so he was in better shape than the boys. Megan knew exactly how to even things out.

All girls knew that even professors had lower status than a 19 year old student girl but constant reminders were used to reaffirm the feminism in the girls. As such professors had to endure weekly discipline session from a student, today Megan was going to give Phillips an extra dose. Looking for a candidate she realized the blonde bookish girl filling in for one of the President's daughter had done an excellent job and decided to reward her.

"Anne, come here." She ordered "Mr. Phillips needs another 8 kicks".

Anne seemed to hesitate which irritated Megan -"He is a professor but first he is a man, never forget it."

"Yes, ma'am!" Anne replied and decided she had to show utmost determination at the professor's expense".

The young girl put the professor through hell and Brock could witness now what has been done to him seconds ago. Innocent looking or not, she had no mercy. Her leg was like a whip going up between his legs until her perfect foot blasted against his hanging organs.

When she was done he was bending as low as the rest of the males in the room. Palms against the wall for support, legs obediently apart and the upper body almost horizontal.

Megan made a gesture indicating Anne to go back to Brock and started demonstrating the next move. From behind him she put her hands on the sides of Mr Phillips hips and without even looking sent a solid knee between his legs.Her knee collided with his nuts and then kept going pushing them up until it squashed them against his lower abdomen. He was shaken to the core and screamed in pain.

Anne used this opportunity to get closer to Brock than she has been able to before and lifted her hand scooping his balls from behind.

He felt a soft hand lifting his nuts and for a moment enjoyed it but the hand soon turned into a closed fist trapping his male flesh.

Anne had already seen the magnificent size of his organs but his hot and firm man's meatballs were a pressure to hold.

Brock hear her whispering very close -"Kate sends greetings". When saying Kate she squeeze hard, never letting go. And she added -"She said these are hers and as soon as she finished high school she will come here to take possession". When she said "these" the level of compression in his nuts went up several notches.

Brock could not believe it, his bitch of a half sister from his father's second wife, who at 16 was still in high school had managed to reach him here, and as Anne's feminine hand was reminding him she had him tightly by the balls.

Anne let go of her crushing squeeze only when Megan order them to begin applying the knees.

As soon as Brock felt his balls free and dropping down low, there were 2 small hands resting on his hips. He believed pain could not get any worse but Anne with her knee showed him he was wrong 10 times. With each blow came a word. "imagine", "each", "blow", "as", "coming", "from", "Kate", "my", "girlfriend", "understood?".

Only after the 10 blows Brock could find the strength to answer in a weak murmur -"Yes, mistress" collapsing then to his hands and knees.

It must be said 90% of the men where down after the girls terrible knees.

Megan gave them 5 minutes and not a second more.

"Let's continue! and you stay there Mr Phillips". She had given him only 5 knees but he was one of the males on all fours.

She went to the 2 men still barely standing and kick them from behind. She was perfectly capable of popping a pair of testicles but she kicked them only hard enough to leave them in the same position as the rest.

With all males now ass up and balls hanging she told them what was going to be the next move.
