Ana still has some surprises for him

Ana smiling theatrically bowed to her audience while other girls ran into the classroom having hear what was going on.

With the room full of girls Ana turned around and proved another 9 times that her first knee had not been a lucky one-off.

After the third knee, he closed his eyes in desperation. Ana paused and very calmly told him "Look me in the eyes or I'll rip them off. You know I will at most get a week's suspension."

He knew she was right so with supreme effort **** himself to open his eyes and fix them on hers. All he could see were her spectacular green eyes and the genuine smile that showed how much she was enjoying it.

Ana found him totally hot and wanted him to be her boyfriend but at the same time her education and conditioning made her 10 times more excited with the domineering position she was taking over him. She had decided they were going to be together but first he had to understand who was in command and what was at stake for him.

After the tenth knee she stopped. He was in a way getting used to it and it was time to try something else. She turned towards the girls and asked them what they thought she should do next. Every girl had an opinion and she got a zillion answers, front kick, back kick, punches, shin kicks, squeezes and even bites. She was probably going to do all that but decided that punches were next.

She gave him 5 minutes to recover, at least partially, and went to work.

Jake was brought back to his hard reality by her voice calling him but more so by the faint feeling of her breath in his sac. He looked down and saw Ana kneeling at his feet, so close that her face was only a couple of inches from his hanging manhood.

"Were you ever punched down here?" She asked casually.

"No, never" He managed to answer before a hard uppercut sent his balls flying up as high as his navel would be. He groaned in pain and she coldly told him "No, ma'am to you boy. Let's try again."

"No, ma'am. Never, ma'am" he quickly replied.

"That's better. Well I love boxing so let's fixed that".

She had only kneed for effect. Somehow she found the apparently subservient pose while at the same time he was totally at her mercy amusing. Standing up but bending as an experienced boxer would and then springing up she used all her body's strength to launch her right fist into his nuts. Her left quickly followed and the one-two sequence repeated over and over. After the tenth combination, he was already screaming but she was becoming really turned on by all this and kept going. After giving him another 20 she stopped.

"My fists are starting to hurt a little, I wonder how it must be on your side." She didn't sound truthfully worried but mocking. I should wear gloves but feeling your meaty testicles squashing against my knuckles is something I would never miss so let's continue.

"Please stop" he managed to say.

"Not yet Jake, I still have to do my speed bag routine" she answered.

Only those with some boxing knowledge understood her intentions but it all became clear when she lulled a lever that spread his feet apart even more and knelt again. Considering his size and the extra elevation of the device, his scrotum hung right in front of her face. With several inches of stretched skin separating his huge balls from his body, he was perfect for what she wanted. The first frontal punch sent his nuts flying back through his legs as much as they could go but they sprung back to their original position right in time for her other fist to find them. She clearly knew what she was doing and managed to make her fists execute a perfect frontal collision with his returning organs every time.

The girls were mesmerized by his swinging manhood and her ruthless display.

When Ana felt her fists really needed a break she stopped went to get a glass of water.
