The bell rang and all the boys and girls started to get up and take their books to leave the class. Nevertheless, Natasha was very annoyed by the behaviour of one of her students. He had been very impertinent with her in the last days and all the class was beginning to go away of her hands. The teacher was intended on ending it in a way where both get understood.

"Hey you! The boy in the last row, I want to talk you now privately" Told the teacher

"Ok!" Told the guy in an arrogant vein

Natasha got even hungrier with his answer. She was ready to use an old secret serum that some friends of her talked about. It seems that it’s called: the final cum serum. It would be the first time that she was going to taste it so she was very excited.

When everybody went out and there were only the student and her on the class, Natasha though that he was ready for her. She got up from the teacher’s chair and walked to the door to lock it. When she turned over, the student felt a strange look in her teacher She looked at him in a lewd and annoyance way.

"Sit down." Ordered her

"Yes" Answered him

"I want to talk about your behaviour in class. You’ve been distracting the class in the last few months and as you can understand, I can’t let you do it" Introduced Natasha

"Yes but…" Started him when the teacher interrupted him

"No! shut up, now I’m going to punish you for what you’ve done. It’s decided and you could say nothing" Told Natasha

Then she walked to her table and opened a drawer to take a syringe full of final-cum serum. She placed her hands on her back so the boy couldn’t see her intentions and walked toward him very sensually. The young boy was sit down and Natasha was getting close to him with an extremely sensual walk. She wore a white satin blouse with very hot tight black trousers. Her foot were covered by sexy high heels black shoes. Natasha was very fiery, her face was second by second a best reflex of her sexual intentions. She was blue eyed, her red lips were very fine and brilliant, her beautiful smile made of her pale skin a sexy woman. Her black hair was in a nice ponytail. Natasha was a slim but curvy woman, she had an incredible cleavage over her blouse that hardly could hide her big breasts. The student could see a black bra under it. He was getting hot so. Natasha got behind him.

"C’mon, get up from your sit and say nothing, your punishment have to start" Ordered her in a hot vein "Don’t say anything and shut up ok?"

"Yes miss Natasha" Answered him troubled

Few seconds later, Natasha took one of her student arms and slowly introduced the syringe inside him. She slowly introduced all the serum inside him getting horny. Natasha was very excited, in a few minutes he will be totally hers.

"What are you doing miss Natasha?" Asked the boy undecided about saying it.

"That’s a part of your punishment. I’ve told you to say anything! Now you’re mine" Told Natasha

When she had finished Natasha felt wet. She decided to humiliate him with some cfnm stuff while the serum was doing its paralyzing effect.

"That’s it. You just have to obey me now" Said Natasha "Get up and undress right now"

"Ok, miss Natasha" He get up and begun to strip himself.

Natasha looked at him while he was undressing. She thought he was very well-built but too distracted in class so he was going to receive his detention punishment. Little by little he was getting close to the first step. When he took off his boxers Natasha looked at his soft cock and said:

"Uuhuh! Very good"

"I’ve finished Miss Natasha, I’m nude" Said the boy

Natasha got up from the teacher’s sit and got off all the papers over her desk. She got close the boy, she cuffed him in his ass

"Stretch you over my desk" Ordered her "As a part of your detention, I’ll handcuff your wrists and ankles while you’re getting quiet"

"Yes miss Natasha" Accepted him.

The teacher was very hot, she was only thinking in making him cum but she wanted to do it very slow and pleasurable. Natasha waited for the guy to get totally stretched over her desk and took of the four leopard furry handcuffs. Natasha walked around the desk caressing the punished boy with her pink perfect nails. She carefully took his first arm and handcuffed it in one corner, then the other one and finally his ankles. The guy was afraid and couldn’t understand what Natasha was going to do.

The boy was now in total submission for Natasha. Totally handcuffed, Natasha was ready to get on the table. She got on the table then she crouched down to unleash her high heels.

"I’ll explain you the game, what I’ve putted inside you is not only a tranquilizer to punish you, it’s a femdom serum that you would appreciate a lot" Said Natasha

"What is it about, what are you going to do?" Asked him

"In a few minutes, you’ll be unable to make any movement, I’ve handcuffed you to avoid that you escape from this room and because I like you like that. When you’ll get totally paralyzed your vital energy will be in your nuts, and then, the game begins" Said Natasha

"What game, Miss Natasha?" Asked the guy

"Once your energy is in the nuts, I’ll make you hot and hot, so you cock get hard for me. When you’ll reach the maximum erection, the serum will make your energy pass from nuts to your sperm, so I will make you cum and punish you!." Said her in a sexy voice

Natasha didn’t let him say anything, she took a pantyhose from her desk and tied it over his mouth. He begun to shake all his body trying to escape but I was impossible, Natasha had attached him very hard. She finally left her high heels and got up on the table. She was ready to get him hard. She begun to move her ass, each leg by the boy’s side, her devil’s dance was very hot. One by one she undo her white blouse buttons Once she finished, her round tits got obvious. She wore a black lace bra but her breasts were bursting over the taut bra. The boy was looking at her stunning teacher when she begun to caress her ass, her sexy sides and finally reached her breasts. Natasha played a few seconds with her tits and got her nipples hard, her black bra seemed to explode.

Natasha felt to boy clam down, the serum was doing his effect, he was nearly unable to move. She looked at him and saw his soft cock, he was almost ready to get hard. So she continued slowly moving her ass and touched her tight pants. She slowly slide down the pants and throw them over the char. Natasha was performing an incredible strip-tease so the boy could see an incredible female dancing and stripping on him. Natasha finally felt how he stopped all his movements.

"Now you’re mine slave. I’ll punish you so you could have your last pleasure" Said the teacher.

Natasha continued playing with herself rubbing caressing her ass rubbing her tits and bra and slowly get her hand inside her black lace panties. She started rubbing her clit and got visibly hot. The student was getting aroused and felt he won’t hold soft. His teacher was on him moving sensually and getting hot.

He tried to think in others things when he felt Natasha’s foot slowly rubbing his cock. The student love girl’s feet and his teacher was playing with her foot and his cock. Natasha caressed with her toe and toenail his dick. A few seconds later she felt a little twitch. She smiled since he would get hard in a few minutes. Natasha was now caressing his cock with her feet and done it for a while. She climbed off the desk and stand by his side. His cock was getting hard but still not enough.

"You’ll wish to come for me" Said Natasha

She put her hand on his chest, slowly descent to his belly, even slower she got the navel and the pubis. She massaged his cock and began to jerk it. The student felt the soft hand over his dick and couldn’t resist and let himself carried along.

Natasha felt his cock getting hard, totally hard and continued jerking, she felt wet knowing that his sperm was now full of his vital energy. She tossed off his cock a few minutes. Up and down, up and down, she wanted to make him beg for cum even knowing he will finish then. The student was totally excited, Natasha’s hand were very nice, the feeling of being handcuffed and jerked by an incredible woman made him forgot he was close to his last orgasm. Natasha smiled him and get even closer Her tits were rubbing his leg. She got off the pantyhose from her student and asked him:

"It’s not necessary cos you’re paralyzed but if I take the handcuffs off, what would you like to do?" Said Natasha while both jerking and caressing his cock.

He hesitated a few seconds and said: "Let me out…"

"Are you sure?" asked again Natasha. Then she licked his cockhead, she squeezed the cock harder and then kissed his ear.

"Mrs. Natasha You’ve turned me on I can’t resist you I would fuck you" Said him

"Fuck me until what?" Asked Natasha with a extremely sensual voice

"Mrs. Natasha make me cum please I’m too horny" Finally said him

"That’s very good, good boy" Said the teacher.

Natasha got up and the student could see how she undressed her panties with an extreme sensuality. She looked him with her panties on her hand and with a malicious smile.

"Want to suck them while I ride you? They’re wet and still hot" Said her

The boy agreed and Natasha put the panties over his face. She took care of putting the wet part in his mouth. He was super hard, his cock was very erected and Natasha very hot. The boy asked her to take off her bra and so did Natasha. She took off the handcuffs and took and placed on if his hands on his left big tit. Natasha wanted to make him enjoy as much as he could.

She loved the sensation of being sat down on his dick, moving her ass and feeling his cock stuck inside her giving pleasure and pleasure. She continued as far as she got another orgasm. Her moans were very sexy and the boy felt the first tickle over his body.

"Miss, I feel I’m getting close" Announced the boy

"OK, let’s do it slower Don’t want you to come still" Told Natasha

She wanted to have another orgasm. She waited a few seconds looking at him, letting him recover so he could hold for her. Natasha then, turned over the cock without taking it out from her cunt and got ready to begin a reverse ride. Natasha reclined behind with one arm and took the boy’s hand with the other one to make him caress her tits. She made him squeeze her nipples and started her movements. The boy felt how her tits were bouncing and held one of them. He was full of pleasure and wanted to cum as he was looking at his teacher’s pony tail waving and rubbing his lips. Natasha’s hair was very nice.

The teacher was bouncing on him and now he was seeing her ass squashing over his belly, an incredible ass was riding his cock. Little by little Natasha felt close to the orgasm and accelerated. When she was close, she stopped, turned over the cock again and continued
