“Good morning class. We have a full schedule today, so let's get started.”

“Everyone, take off your pants and underwear, get your penises hard, and sit down.”

The class stripped from the waist down. A few guys were already erect, the others played with their penises until they were hard.

''Class, this morning, you are going to learn the art of fellatio, also known as, how to give a blow job. This afternoon, you will learn the art of but fucking.”

Every penis flexed at hearing this.

“Pair-up, one of each pair will suck the other's penis until it cums. Then you will trade places.”

”Be sure to lick the coronal area, that's where the head joins the shaft, and be sure to stick your tongue in the pee hole.”

The guys getting blown started moaning and bucking their hips as soon as lips touched their penises. It was their first blow jobs. The guys traded blow-jobs all morning. Each penis came four times that morning. Lunchtime came and the guys found-out that they couldn't wear pants until after their penectomies, even at home or with family.

Professor Johns was visited by his colleague, Professor Mia Lane, who teaches the sex class for the newly penectomized students. She was clearly in a bad mood.

“Professor Johns, will you please explain why you insist on having your students experience sex before their penectomies! It just makes it harder for them to accept the penectomy, and it makes my class harder to teach. Aren‘t you supposed to make it easier for them? Aren‘t you supposed to make it a positive experience?”

“Professor Lane, you misunderstand the purpose of my class. It isn't to make it easier for them. It‘s to make it harder for them to accept. The goal is to make their lives a living hell. My life hasn‘t been easy since my penectomy. No man is ever happy after his penectomy, but the law requires every eighteen year old guy to take my class and then have his penis removed. That‘s also why penectomies are always done without anesthesia or pain killers.”

After lunch, Professor Johns introduced the class to ass fucking.

“Class, since your penises are erect, you will now learn the art of but fucking. You start by spreading his ass and licking and fingering the hole. Once he loosens up, take your penis, place your pee hole against his ass hole, and thrust your hips forward to insert the full length of your penis in his hole. Pull out and repeatedly thrust until your penis cums.”

The students took turn fucking each other. Every penis came four times that afternoon.

Sucking and fucking continued for two weeks. When the students weren‘t in class, they fucked and were sucked by dickless men who saw their penises. Then the big-day came.

“Class, today is the day you've been preparing for. Today you become men. Today you finally get your penectomies! Then you will no longer be boys, you will be men!'' said Professor Johns.

Some guys started crying. Others started jerking-off. A few started to both jerk off and cry. Soon the entire class was sobbing as they stroked their erect penises.

Men, cutters, came into the room. There were two men for each student. The men took off their shirts and pants. The students got to see a close-up view of a penis-less crotch. The men took advantage of the real penises and sucked them and were fucked by a real penis.

The cutters tied the students down and began the penectomies. The cutters started by taking a knife and cut around the base of the penis, just through the skin, but not into the shaft. The students screamed, and rags were stuffed in their mouths. The skin was pulled forward, as tears flowed down their faces. The cutters started cutting into the shafts, locating the arteries and veins supplying the penis with blood. The veins were tied off and the penis swelled to its biggest and hardest erection possible, then the arteries were tied off and the cutters started to inject a plastic polymer into the arteries. The polymer contained a special, government-mandated, chemical. The only purpose of the chemical was to inflict extreme pain on the penis. The veins were cut and the blood started to flow out of the penis, being replaced by the polymer. The students were screaming through the gags, their bodies tense, trying to break the bonds that held them. When the polymer had completely saturated the penis, it was slowly cut off. The polymer quickly hardened and plasticized the penis.

It took an hour to do the penectomies. The students were no longer boys, they became men.

The newly penectomized men were forced to suck on their former penises.
