Title: Strict personal trainer.

He walked into the room. Laying on the bed was a boy, hands bound behind his back in loose cuffs. He was covered from neck to foot in a shiny plastic suit and on his head was a thick black plastic blindfold, tied tightly over his eyes. Covering his whole head was a loose clear plastic bag, now fogged with sweat and condensation. The only other thing he had on was under the suit, a full steel chastity cage, the front of which covered all of his privates in a shiny cup which had held his balls and penis locked in place for over a month now.

The boy had been in the plastic suit bound up for an hour, sweating and generally being uncomfortable. But that was the point of the training, he was there to get used to being uncomfortable and bound. Train hard, fight easy they say. Well this boy hadn't been hard for a while but the training was certainly rigorous. He hadn't felt cotton in weeks, all of his outfits bieng plastic or rubber so that he sweated constantly. His body had been toned by a strict liquid diet, force fed to him via an inflatable gag and by hours of forced exercise under threat of beating and punishment, a strict altitude training mask attached as he ran for miles, breathing in half the oxygen he needed.

Quite why he was there, well his temporatu master was a personal trainer. He was just a little more personal than many others. Forget a 6 month program to lose 20lbs, he would take 8 weeks and you'd loose 100. You wouldn't like it, but sure as shit you'd look amazing at the end of it. And you'd pick up a few “skills” along the way, gain a surprisingly high tolerance to heat and sweat, be able to sleep completely restrained and pick up a fetish for heavy unbreathable materials….

Today's lesson for the boy on the bed was to please another man. The trainer slowly unzipped his fly and walked towards the bed, unfolding himself from his pants. He was going to get a handjob from the bound boy, and if it wasn't good, the boy was going to suffer until he learned to get it right.

If he didn't seem to be learning, the punishment would get harder and harder until he got the idea.

The trainer slid onto the bed behind the boy, his cock lining up with the boys cuffed palms. “Please me” said the trainer. For a few seconds the boy did nothing but make a confused “huh” noise. The trainer grasped the base of the bag and wrapped it tight around the boys neck cutting off any fresh air. As the bag tightened against the boys face the trainers cock got hard in the boys hand and the boy seemed to get the idea, slowly he started working the cock awkwardly in his bound hands.

Just as the boy started to struggle a little with the lack of air, he stopped stroking. The trainer he'd the bag firmly. “I didn't say stop boy. If this isn't fun for me your not gonna breath”.

The boy whined but diligently resumed the stroking, really struggling now as the bag vacuum formed over his face. The handjob was still poor, but they would get to that. The trainer released the bag and let the boy breath, and the boy gasped and sucked air in fast. He also forgot what he was doing, and stopped stroking. After half a gasp, the bag was sealed again “fuck sake boy, remember your place” The hands started working again, but the boy hadn't got enough air and in 20 seconds in the bag was tight against his face again. The trainer let the bag go, and the boy sucked air in again, almost panicked, and skipped half a beat of a stroke.

The bag closed off again. The trainer didn't do half measures. This boy would learn to keep going until he passed out if he had to. Another 20 seconds and the bag was almost sealed against the boys face again, but he hadn't learned last time. So it stayed on, until the boy was struggling hard, the stroking still going though, and this time, when the bag came off… it continued. Not skipping a beat.

But that isn't training, training takes endurance, repeatability. So after a few deep lungfuls, the bag was closed off again, and again, and again, until 5 times in a row, when the boy got air back, he just carried on jerking away.

“Good boy, now, let's improve your technique a bit shall we. Slow the strokes down and make them deeper, all the way up and down. And use that other hand to stroke my balls”

The boy blindly fumbled for the balls, catching them roughly and hard. The bag snapped shut as the trainer winced. “Your fucking paying for that” holding the bag with one hand the trainer reached for a thick leather strap, it was an old school tawse and it weighed a ton. The boy clearly hated it whenever it was used, but with no way of seeing what was about to happen, he couldn't tense or dodge. The strap came down hard on his backside causing him to yelp and falter in his strokes.

That earned him another whack, and another, and another. The bag was flapping wildly now and the boy was heaving, struggling and whining in pain, crinkling all over as he struggled in the suit.

The trainer released the bag, giving the boy another whack with the tawse as he tried to inhale, making him cry out with air he didn't have. The boy was sobbing, choking and generally being fussy. But he was trying still with the handjob, and he was now working those balls well.

He got a light reprieve from behind choked until he stopped bitching and struggling, and then the bag closed again and the strap came down. This was training, and even if it was unfair that a blind and cuffed boy was being punished for messing up something anyone could have done, he had to learn.

Another 20 strikes of the strap and 2 minutes and the bag was sealed tight again, this time the boy was whining and thrashing about when the bag was undone. He looked like he would beg soon to be let out. But that wouldn't happen, and he knew the punishment for talking.

For a third time, when the boy had settled down, the bag sealed and the strap came down. It didn't even seem like a surprise to the boy this time, he knew he had messed up and was in for a rough time. Through all this though, that handjob was getting pretty good, precum was oozing out of the trainer and lubricating him up, making it even more enjoyable. The trainer didn't know what was doing it for him, the struggling whining boy or his hands, but it wasn't half bad. But the boy had to learn, and damn that thrashing seemed to be doing the job.

This time the trainer got 30 strikes of the strap in before the boy was convulsing. Best stop that, the trainer could feel and see the welts through the plastic. This little fucker was gonna be sore for a few hours, and sitting down would be hard. Shame his workout tonight was going to be a 100km bike ride on that sore ass.

“Start working the tip” immediately the boys hand on the shaft moved up, found the slick tip and started to caress it carefully, causing a big spurt of precum to pool around the trainers tip. He was so close, what he needed was just to see the boys face sucked against that bag a bit more. Reaching down beside the bed, the trainer pulled out a collar and snapped it closed around the bag, sealing it tight to the boys neck. As the bag started to seal against the boys face more precum oozed out of the trainers cock, until eventually he couldn't hold it and he shot all over the boys plastic coated ass.

After a few seconds of squirting and enjoying the orgasm the trainer said “slow, slow… stop” the boy obliged, now still except for the slowly increasing expanding and contractions of the bag, each breath getting strained as the air got thinner.

As a reward the trainer removed the collar before the air ran out. The inside of the bag was now slick with sweat and slobber from the boys choking and sobbing. It clung to his face even when it wasn't closed. The trainer pulled the bag off and saw relief on the boys face. It was going to be short lived as he used the bag to wipe the cum off of the boy, binned it and picked up a smaller black bag, tugging it roughly over the boys head and blindfold.

He then reached into the boys plastic outfit, feeling around the piss hole on the chastity device. It was slick with precum.

“Well done boy. You can have an hour there, then I'll get you fed and you can begin your exercise. Oh and that pre-cum you leaked there, that counts as an unauthorized orgasm. You'll be punished for that later ”

The boy wined and struggled against his cuffs a little as the trainer closed the door, leaving the trainee to his suffering.
