This is a fictional story about a horny 19 year old, who is turned into a prejac against his will, is held in chastity for days or weeks and only gets a few ruined orgasms and some ballbusting – getting worse and worse.

All Characters are of legal age

Part 1 – the first Week

Luke was 19 when he was conscripted. Since the fertility of males all over the globe dropped drastically, the government organised camps for collecting semen. The few fertile sperm cells a man could produce over months were extracted here. All males of at least 18 years get tested for their sperm quality each year. Now it was Luke's Term to help save humanity. He didn’t know if his sperm quality had increased or if the average quality had dropped further making his sperm valuable now.

He knew he didn’t have a choice but to do his duty now, but he was kind of glad. His financial situation was really bad – something he wouldn’t have to worry about in one of the ‘sperm camps’. He was on the bus to camp right now and would arrive in about 15 minutes. All he knew was there are strict rules and he would donate his cum on a regular basis. His dick stirred when he thought about the donation. He wanted to start with a great performance, so he had saved up his sperm for three days. He usually jerked of at least two times per day, so this was gonna be a massive load. It usually didn’t take much to make him cum and his dick was much more sensitive now. When it reached its full 9 inches and rubbed against his leg he had to bite his lip to suppress a moan.

Luckily Luke got his dick down before arriving, but it got up again in the waiting room… damn. After some waiting a woman in her thirties picked him up and showed him his room. He followed, hiding his boner behind his jacket.

‘This will be your quarters. You will have to do some minor tasks while you are here, but your main objective is to work out, eat healthy, sleep sufficient and therefore produce the highest possible quality of sperm.’ Lukes dick started to get hard again. ‘There are strict rules. You will make a donation once in 10 days. This period of time has shown the best results.’ Now Luke was irritated. He had expected a donation on a daily basis. ‘In between donations no ejaculations are allowed.’ Lukes jaw dropped … ‘If you don’t obey these orders, there will be a punishment. If you spill any sperm in between, your Penis will be locked in a chastity cage for the next 10 days to make sure nothing gets lost. If you spill any drop at the donation the same applies.’

These rules left him speechless, but she continued: ‘Now you know the safety measurements. I will continue with the punishment. For the first three weeks you will be isolated, before you get classified according to your reliability in these matters. If you cooperate, you will join the others and will only be caged for a 10-day period if you should spill any sperm. If you are rated unreliable on the other hand, you will stay isolated and be locked in a chastity cage for 3 months. After that there may be another classification. Of course, you can always get in isolation if you misstep too often.’

By now Lukes boner was gone and he dropped on a chair. What had he gotten himself into? ‘Oh, and don’t try to relieve yourself in secret, we monitor your body punctiliously – so we will know. And be warned: our doors are well guarded and you don’t even want to know the consequences of a desertion attempt.’

After different stages of despair and arousal Luke tried to get the best out of his situation. His quarters offered anything he needed and also some comfort. The first two days he spent exploring the surrounding he could enter and since precum was not prohibited also with edging. A lot of edging.

On day 3 in camp (day 6 without cumshot) it was driving him crazy. Just caressing his dick, he knew he wouldn’t be able to hold back much longer so he stopped touching himself completely. So, seven long days he tried to focus on working out and avoiding any sexual thoughts – more or less successful.

In the morning of day 10 (day 13 without orgasm) Luke was constantly hard and his balls were aching horribly. At 10:00 am he was picked up by another woman – more attractive than the first one. He tried to hide his massive boner, but she didn’t even look at his crotch. Luke entered the donation room for the first time. There was a bed, a mirror and a transparent tube for the donation – at least a little cosier than he had expected.

When he was alone he hastily undressed. By pulling down his pants his raging boner slapped against his belly and sprinkled some precum up to his chest. He watched himself in the mirror. He had always been in good shape, but the first week of working out didn't show much improvement yet. He flexed his sixpack and watched his throbbing 9 inches pointing against the ceiling.

Horny as hell he laid on the bed and intended to take it slow and enjoy. He started by rubbing his chest and gently caressing his cock and balls. The slightest touch made him moan. He grabbed his dick and started to jerk it the first time in 13 days - very slowly. It felt amazing and the precum kept flowing! After less than 30 seconds (about 15 jerks) he was already getting close – way too fast! He stood up and moved to the tube.

There was no way to hold back now! He gave his dick 3 more strokes until his orgasm started. He rammed his dick into the tube right before the first massive shot spilled into it. But now he realised he hadn’t thought things through. He couldn’t touch his dick anymore inside of the tube and now his 13-day orgasm was going to get ruined! Moaning in lust and despair he tried to fuck the tube while his second and third shot burst into the tube – but he didn’t get any friction. Pumping harder he caught his right ball between the tube and his body full force. The pain almost made him stumble – but it also seemed to increase the orgasm and the fourth shot was massive. He kept hammering vigorously against the tube, crushing his right ball four more times until his vision blurred and his orgasm finally subsided. He fell to the floor, panting heavily, the right ball aching extremely and his dick still rock hard.

Seconds later the woman entered and looked him up and down judgingly. ‘Time to get back to your quarters.’ ‘No… wait! I have more to donate! Let me go again!!’ And he started to jerk his dick still lying on the floor. He felt he would cum again in less than a minute. There was so much pressure left.

‘No. The rules are clear. Once in 10 days or you get caged.’ she answered unmoved. ‘No… please! … That’s cruel! I’m still horny as hell!’ he whined. ‘Not my problem’ she answered, taking a metal chastity cage out of a box.

Resigned, frustrated, still rock-hard and with blue balls Luke came back to his quarters. He felt even more horny than before now. The next week was going to be much worse than the first…
