1. Slow recovery.

 

Hinata's spirits were higher than when she first emerged from the stables, decked out as a Pony-girl, 24 hours earlier. The bench she was lying on wasn't ideal, but she had just had a good night's sleep and felt alive and refreshed. Distant noises within the stables complex had woken her, but for the time being, she was unable to see what was happening, because of her collar and her position in the stall.

It was the most bizarre sensation to have woken and discovered herself virtually naked and tethered to a padded dais. When she arrived the previous evening, straight after the races, a ring on her collar had been padlocked to the front of the bench anchoring her there.

Miss Peabody hovered while Rina released her arms from the binding, to ease her shoulder pains. The driver then attached her wrists low on the front of the dais. Her legs were parted and strapped to the back of the solid structure, leaving her exposed and vulnerable.

The other six members of the Black team, four boys and two girls watched attentively so that the sports mistress wouldn't have to show them the procedure again. Her bench was positioned so she was facing the back wall and because of the short tether it was almost impossible to look over her shoulder.

She was lying parallel with a Pony-boy, Karl, who was fast asleep and snoring heavily, not six feet away from her dais. His muscular figure dwarfed her, especially when he was off the dais and moving around.

His bench was higher and he was facing in the opposite direction, toward the front of the stall. When Hinata looked sideways she could see his hairy naked ass and a pair of huge balls protruding from the back of his thighs. His penis was out of sight, but a heavy chain wasn't. It looked as though the tech guys had permanently welded the ring it was attached to, round the base of his genitals.

The restraint was having the effect of accentuating and tightening his scrotum, turning his ball sack dark purple. If he turned his head sideways he had an uninterrupted view of her naked ass and pussy, because of the way they had spread her thighs.

Karl was lucky on two counts - he wasn't tethered to his dais and he had about 8 feet of chain, giving him limited movement around the stall. Thankfully, the chain wasn't long enough for him to get behind her and drive his cock into either one of her unprotected orifices.

Hinata was mightily relieved that the chain held him back, but horrified it was long enough for him to take up a position in front of her. It had been a relief to be brought to the stall and laid on a bench for a rest, but it was a huge shock when the mistress showed the trio of girls how to guide the boy's cock through the ring gag.

Then, once he was lined up, the team stood back to watch him aggressively fuck her throat. The lad thrust his hips rapidly, pumping his shaft at an eye watering speed. Rina, Akira and Yuuko stood gaping at the spectacle, no doubt thankful they had avoided the Pony-girl role.

The Pony-boy, apparently, had been behaving badly, but when Miss Peabody told him that he wouldn't be allowed to spear his filly, he quietened down. Hinata was grateful that she had been given fellatio practice before being transformed, but it was nonetheless a humiliating experience in front of an audience of her friends.

Karl had just withdrawn his flaccid cock when Rina asked a question. "What's to stop him from fucking her throat all night, Miss?"

"Well, in the first place, that wouldn't be physically possible, but the main reason is this little device."

Miss Peabody lifted the boy's ball sack to reveal that his cock collar had a large metal protrusion at the back, rather like a padlock.

"Uhhhhh!" the lad complained when she pulled it forward.

Hinata listened, fascinated to hear what was going on with the boy's cock; and she wasn't surprised to see his shaft stiffen as the sports mistress fondled his genitals.

"That ring looks very tight, Miss. Does it hurt him?"

"Yes Rina, now that he's become excited again, but the device helps him to lose his erection."

"How does it work? And what does it do?"

"It's complicated, but the electronic gizmo emits a signal that confuses the lad's nervous system. It interferes with the messages that are sent to his brain. If the signals that arrive are scrambled, the brain doesn't act on them and the penis doesn't fill with blood. It's a simple device that is successful in most cases."

"Most cases?"

"Miss Wainwright was saying that some young men are so virile they can still become excited with the collar switched on. However, we have tested all sixteen of the new intake and all the collars appear to be one hundred percent effective."

"So when are you going to switch them on?" Akira asked.

Miss Peabody went to a shelf at the side of the stall and returned with a remote controller.

"I'm going to switch it on now, but to demonstrate its effectiveness I'd like one of the stable girls to start masturbating him."

"His cock is still sagging," Yuuko pointed out.

"Then get your lips round it girl!"

The teenager's face betrayed her disgust, but she stepped forward and stooped in front of the lad. Like Hinata, the Pony-boy had been in the latex moulding machine and had a curved rubber corset melded to his body, along with knee length boots on his feet and calves. He was forced into a bent stance, so Yuuko had to drop to her knees in order to get her mouth on the end of his cock.

"Oh! That didn't take long!" she exclaimed, when his shaft immediately started to stiffen.

"Uhhhhhh," the lad moaned, probably due to the tight collar gripping his shaft.

"Use your lips and squeeze it firmly girl, like I taught you in the lesson."

Yuuko got to work, lollypopping his crown and pumping his veined shaft. Miss Peabody, who was standing behind the kneeling girl triggered the collar with a simple push of a button. A red light flickered, signalling the device was activated.

"He's still stiff, Miss," Akira said cautiously.

"Akira, bear in mind he has an 18 year old girl's lips wrapped round the end of his cock ... there, look he's losing it."

Hinata stared at the demonstration unfolding right in front of her eyes. Ring gagged and fastened to the dais, she was unable to contribute to the conversation, but she was fascinated. Sure enough Karl's cock lost its rigidity and became floppy. Yuuko dropped it as if it had suddenly turned into a live snake, then watched it shrivel until it was just a couple of inches long.

"Urrrrrrr," moaned Karl, visibly disappointed at the loss of his libido.

The lads remained silent and looked very uncomfortable, but Rina was animated and the most inquisitive of the three girls.

"Is this happening to all the boys at the moment?" She glanced at their pale faces.

"No Rina, they have been fitted with a different model that has similar functions."

"So they can get hard when they want?"

Again the boys looked uncomfortable by the conversation.

"Okay Rina, seeing as you've asked, I'll briefly explain. During your fellatio lesson two days ago I told you that the boys are allowed one minute erections before the collar starts to punish them. Well, on two minutes the technology kicks in and they go flaccid for a set period of time."

"How long Miss?" It was Yuuko asking the question.

"It depends. With each violation the punishment is sharper and the period of flaccidity gets longer. Five violations in any 24 hour period and it shuts the cock down completely. If it reaches that point the boy has to report to the principal with a good explanation."

"Are they punished for excessive use?" Akira asked.

"Yes and resetting their collars can be delayed if they show signs of being habitual masturbators."

"How do you know what they're up to Miss?" Yuuko asked.

"Their cock collars automatically transmit the wearer's behaviour to a central database."

"So they're always switched on?"

"Yes, at certain times of the day, but their behaviour is still monitored. Each year has a different signal, so we can differentiate between the younger and older boys. Second and third year boys like these four ..." She gestured toward Tomoni, Sura, Yasu and Ichiro. "... are allowed a little more freedom than the first year intake, but every boys' behaviour is scrutinized with a fine toothcomb.

Miss Peabody brought the conversation to an end and after they had settled Karl on his bench, the girl's gave them both a feed and then left for the night.

Hinata, staring out of a small window, guessed that it was early - maybe 7, or 8am and hoped she wouldn't be taken out into the damp morning air. Looking around the draughty, open ended stall, made her regret volunteering for the role of Pony-girl. The vile place was only fit for animals, not humans in restraints. Karl was lucky in that he could get to his feet and take a piss, or a shit in the corner at the back of the stall, where a tray of woodchips had been placed.

She on the other hand had to let it just trickle out onto the floor. They had put her on a liquid diet so her bladder needed emptying several times during the night. She lifted her head and listened. Yes, it was definitely the sound she heard earlier, only much closer. Then her heart leapt into her mouth when she heard what she thought was a foot being placed on the wet floor behind her.

"Urrrrr!" she exclaimed, when two warm hands settled on her prominent ass cheeks.

"Shhhhhhh! You'll wake the stallion," the man hissed.

The voice was too distorted to recognise, but she suspected that it was her leader, Tomoni.

"I want to be the first one in your virgin hole, Hinata."

The boy was in a hurry, for only a few seconds passed before she felt his crown prodding her soft entrance. Then he was in her, driving deeper and deeper ...

"Arrrrrrr," she moaned softly, surprised by the breath-taking sensation generated by the lad's thrusting, plunging motion.

Whoever it was had a long cock and he didn't stop until he was nudging her sensitive extremity. Hinata had blown the lad in their room while Miss Peabody looked on, but she couldn't tell if it was the same cock in a different orifice.

"Better that a silicone dildo, hey?" he whispered.

It was a good job the bench was securely anchored to the ground, because the lad started hammering his cock into her at a thunderous rate. Hinata suspected that the boy only had two minutes, before his cock collar kicked in and shut him down.

"Ohhhhh fuuuuuck," he moaned as his and Hinata's orgasm arrived.

She had never experienced anything like it. Being bound and gagged only accentuated the incredible sensation that tore through her entire body, while the lad pumped his jiz into her deepest extremities. She heard a whisper, but only realized that another lad was waiting his turn when a second cock slipped into her gaping portal.

The remnants of her orgasm were still sparkling around her nervous system as the newcomer began pounding her sopping orifice. The second boy though was more adventurous, for after just 30 seconds in one, he slipped out and penetrated her tighter orifice in a quick slippery move. He piston fucked her for a while, but he was taking longer and had the embarrassing experience of losing it before he shot his load.

"Fuck, fuck, fuck," he hissed as he withdrew.

A quick slap on the ass was the only departing gift as the pair slunk off into the grey misty morning.
