The sun was shining, and a pleasant breeze was making the long grass wave idly in the fields. Liam was enjoying the day. He was walking with Sofia at his side, holding her hand. Sofia swung her arm forward, giving him a little bump with her hip while his hand was out of the way. He bumped her back with his shoulder.

Sofia was dressed in her customary bikini top and harem pants. They were blue today, with matching toenails, peeking out of her sandals. They made their way past a fallow field. Summer flowers were mixed with long grass, gone to seed. A pair of first year trainers were having a collar pet duel in the field. Two sabre hounds snapped at each other as their masters fumbled with their wristbands trying to control the animals. Blood was flowing as one of the hounds tore into the shoulder of the other. Liam and Sofia ignored the duel as unimportant.

“We’ll be graduating soon,” Sofia said, bumping him with her hip again, “We can get away from this place and find our adventure.”

“We have to pass the final exam first,” Liam replied.

“Shouldn’t be a problem,” she said, “We’re both ready.”

“Yeah, fair enough. Weird thing is, from what I’ve heard, a lot of students quit a week before the exam. The week we’re in now.”

“Quit? Why?” she asked.

“I have no idea,” he replied, “But apparently it’s a thing.”

They arrived at their destination. It wasn’t much, just some benches set up at the edge of the field. It was a common spot for student trainers to congregate and practise with their collar pets. Sandra was waiting for them, sitting on a bench.

Sandra was Sofia’s friend from childhood. They joined the trainer program together and often helped each other study. She was friendly with Liam, but she could be a bit prickly at times. He wasn’t complaining though. Sandra was fiercely loyal to Sofia, and she was easy on the eyes.

She was wearing hiking boots, short shorts, and a crop top. The outfit showed a lot of smooth leg, and she had wide hips which gave her a shapely butt. The crop top and a push up bra helped to accentuate her small breasts. Her toned waist was accented by a gold belly button piercing. Her lips were a wine red, presumably from lipstick, and she was wearing a little bit too much eyeliner. The heavy makeup obscured her eyes, but Liam knew that they were almond shaped and slanted upwards at the outer corners. She was of mixed heritage, one of her parents was born off world.

Her hair was under a nondescript ball cap, kept in a low ponytail that reached down to her mid back. It was lavender in color with darker highlights. Up until recently, he assumed that she dyed her hair, but Sofia set him straight on the subject. It was her natural hair color. An odd aspect of her mixed heritage.

“Hey there princess,” Sofia said, drawing a scowl from Sandra.

“Yeah, keep calling me that, see what happens,” Sandra said, standing up.

They hugged each other in greeting. Sofia made a show of it, bouncing on her toes to press her breasts into her friend’s smaller chest. Sandra just shook her head in resignation, hugging her back. As they released each other, she made eye contact with Liam and smiled at him. She had green eyes that contrasted nicely with her lavender hair. He nodded back.

“I guess this is where we separate,” he said to Sofia.

That drew a reaction from her. She released her friend and turned back to him. Pressing into him for a goodbye kiss. Her soft lips opened and her tongue darted out to taste his. Her eyes were open as they kissed, full of promises for later.

“Ugh!” Sandra exclaimed, “You can have her later. She’s mine for now.”

They broke the kiss and Sofia bounced back to stand with Sandra. They linked hands and started walking away together. Liam watched them go for a moment and then started on his way as well. Within moments, he realized that all three of them were going in the same direction.

“Ummm, this is awkward,” he said as they looked back at him.

“We’re supposed to have separate classes today,” Sandra said. As they walked, there were more students, members of the same class walking in the same direction. At a glance, all of the students were female.

“Yeah, the message I received from professor Brevifolia was to go to Camsel Gym,” Liam replied. More of their classmates joined them as they drew closer to the building containing Camsel Gym. All of the classmates were women. Some of them were giving him weird looks. He was beginning to feel distinctly unwelcome.

“Ummm Liam, that’s the same place we’re going,” Sofia said.

“Maybe Brevifolia thinks he’s a girl,” Sandra said.

“Maybe he really is a girl,” a woman’s voice called out from behind them.

He looked back to see Evelynn. She was a short woman who had her hair up in pigtails. Her clothing was very childlike, a schoolgirl style dress with long knee socks and a tie. It looked like a school uniform, but there was no school uniform for trainers. Her face showed the artificial youth of a regeneration treatment, which put her at thirty-five years of age at a minimum, and probably a lot older. Every time Liam saw her, she was dressed in a similar way. She seemed to have a weird fixation with dressing like a child.

“I can assure you from personal experience that he isn’t a girl,” Sofia said.

“Ewww,” Evelynn replied.

“I think professor Brevifolia gave you the wrong location,” Sandra said.

Camsel gym was easy enough to find, they’d all been there dozens of times. Sandra opened the door and they went inside as a group. The gym consisted of a walking track around the outside of the room, surrounding an area with a padded floor in the middle. The padded floor was large enough for two trainers to work with collar pets simultaneously without getting in each other’s way. There was seating on one side, enough for a couple dozen people to watch a demonstration in the padded area. A large folding table was set up off to the side.

Professor Brevifolia was in the gym, standing near the chairs. He was wearing his customary plaid brown suit, custom fit to his small frame. He was talking with Priestess Josephine and a female police officer. Priestess Josephine’s tall frame made her look like she was towering over the smaller man. She was wearing a thin robe overtop of a non-descript tight bodysuit. An errant breeze plucked at her hair and made the hem of her robe dance. Liam was expecting both of them for today’s class, but the police officer was a surprise. She was in uniform, of course, including a plasma pistol on her hip, and a truncheon on the opposite side. He wasn’t sure why she would be needed for the class, but he also didn’t know why trainers quit during this test. He wasn’t entirely sure what was going on.

Liam made his way towards the center of the gym. It was all women in the room, with the exception of Professor Brevifolia. Liam was the only male student. He was about to ask what was going on, but Evelynn beat him to it.

“Professor why is Liam here?” she asked.

“Yeah, I don’t want to strip in front of him,” another girl called out.

“Do you want to field this mister Smyth?” Professor Brevifolia asked, using Liam’s last name.

“Ummm, I don’t know why I’m here,” Liam replied, “Did you invite me to the wrong class?”

“It’s Liam C Smyth, correct?” the professor asked, consulting his tablet.

“Yes.”

“You don’t know?” the professor asked.

“Know what, sir?”

Professor Brevifolia turned to the priestess and showed her something on his tablet. She looked at it and they started talking to each other in low voices. Liam couldn’t hear what they were saying.

“Maybe you really are a girl,” Evelynn said.

“Okay, mister Smyth. This is not how you should be learning about this. Your parents should have told you, but we are on a tight schedule, so I’ll make it a teaching moment,” Professor Brevifolia said, projecting his voice so that everyone in the room could hear him.

Liam flinched at the mention of his parents. There were a lot of things they should have done for him. Apparently, there was a new way in which they chose to screw him over. Sofia stepped over to his side and took his hand in both of hers, silently offering her support. She knew his family history.

“Miss Grace,” the professor said, speaking to Evelynn, “Can you tell me what percentage of female sabre hounds can be captured using a standard collar?”

“Ummm, seventy-five percent?” Evelynn asked after thinking for a moment.

“That’s correct. Similarly, what percentage of male sabre hounds can be captured by the same standard collar?” Professor Brevifolia pressed. Evelynn looked blank. She didn’t know the answer.

“That’s easy, its twenty-five percent,” another student called out.

“Oh, I get it, holy shit!” Sandra said, looking at Liam.

“What?” Liam asked. He didn’t understand what this had to do with him. Sofia squeezed his hand, comforting him.

“I still don’t get it,” Evelynn said.

“Let’s walk through it then. What percentage of human females can be captured with a standard collar?” Professor Brevifolia asked, pointing at Sandra for the answer.

“Ninety-nine percent,” she replied confidently. Everyone knew that answer.

“And thus, what percentage of human males can be captured by a standard collar without any special preparations,” he asked.

“One percent,” Sandra replied looking straight at Liam.

“Wait, what?” Liam asked as the meaning of what they were saying started to sink in.

“You can be captured just like any of the women in this room,” Brevifolia explained, “It was in your medical file when you joined the trainer program. You should have known. Your parents should have told you when you were a child. You don’t need a Tiresias stone or infusions of Salmacis. A capture device will work on you directly. It’s actually considered to be an advantage by many people.”

“Does that mean he’s really a girl?” Evelynn asked with an evil smile. Liam lifted a hand towards her, extending his middle finger.

“No, it doesn’t mean he’s a girl, or gay, or anything else,” Professor Brevifolia said, “It’s just a quirk of his physiology. There’s nothing visibly or psychologically different about him. It’s just random chance.”

“What you call random, we call a blessing from the goddess,” Priestess Josephine said, stepping into the conversation, “Do you have a priestess who is helping to guide you through your life path?”

“Ummm, what? No, that’s for...” his voice trailed off. He was going to say that was for girls, but then he remembered how it worked. The priestesses would only start providing guidance for girls when they turned eighteen and could be captured by a collar. Sofia squeezed his hand, this time with excitement.

“I knew there was a reason I liked you,” she said bouncing on the balls of her feet and giving him another squeeze.

“Let’s talk later,” Priestess Josephine said, “But for now, we should move on.”

“Right,” Professor Brevifolia said, “The purpose of today’s activity is to give each of you the experience of what it feels like to be captured and wear a collar. This is a mandatory requirement in order to graduate. I don’t want to hear any complaints. This was in the curriculum when you signed up for the program two years ago.”

Some of the women in the room looked unhappy, but nobody was complaining. The professor was right. They walked into the room knowing they would be captured today.

“This will help you to become better trainers. After this, you’ll have more empathy towards your collar pets. You’ll have some idea of what they are experiencing,” Brevifolia continued, “Officer Watson is here as a witness. She will not be interacting with you unless one of you panics and uses the failsafe.”

Officer Watson gave a little wave as the class turned to look at her. That was all the explanation given or needed for her presence. It also helped to explain why some people didn’t make it past this class. Either they used the failsafe, or they chickened out and refused to be captured.

“To be clear,” Brevifolia said, “Using the failsafe will be grounds for immediate expulsion from the program. If you want out of the collar, then all you have to do is ask. There will be no collar girl abuse today, thus there will be no need to use the failsafe.”

“Okay ladies,” Priestess Josephine said, “I know some of you have tried this before. Please put your hand up if you’ve been captured.”

Sofia proudly raised her hand. She had no shame and almost seemed proud of it. A couple of other hands went up around the room. Sandra tentatively raised her hand as well.

“Wow, really?” Liam asked.

“Shut up!” she said, her cheeks going red.

“Great! That’s wonderful,” Josephine said, “Now, I need one of you, who has her hand up, to volunteer to go first.”

Sandra dropped her hand, as did most of the other women in the room. Sofia’s hand was the only one still in the air.

“All right hun, looks like you’re up,” Josephine said.

Sofia gave Liam’s hand one last squeeze and then she went to join the priestess in the center of the gym. She looked proud to be there, happy to be the first one up. Priestess Josephine pulled a capture device out of one of her pouches. It was the standard model, a wristband connected by a short post to an open collar. Somehow, it looked more menacing now that he knew it could be used on him. Josephine twisted the handle, extending the connecting rod. With a second twist she set it so that it was ready to capture a person.

“A careful trainer will make sure that the capture device is properly lined up in order to minimize discomfort,” Priestess Josephine said.

Sofia smiled at her and lifted her chin, presenting her neck. Josephine positioned the capture device in front of her neck so that the post was in line with her chin. It was the perfect alignment. Josephine smiled and then intentionally twisted the device to the side so that she was at a forty-five-degree angle before pressing it into Sofia’s neck.

Sofia gasped in alarm and tried to pull away, but she was too late. The collar snapped shut like a spring-loaded trap. She squirmed as the collar held her neck in an iron grip. It slowly rotated on her neck, lining itself up into the proper position. Sofia started turning red, her mouth opening and closing as she tried to breathe but couldn’t.

“Today, we’re here to learn what it’s like to be captured. This isn’t a game or some sort of overly complicated foreplay. This is surrender. This is losing your freedom. I am going to dominate you. I will make you do things you don’t want to do. I will force you to submit to me,” Priestess Josephine said to the class as Sofia struggled, “I know what some of you are thinking. You figure that you’ll just follow my orders without surrendering inside your mind. That’s not how the collar works. In moments, the payload of nanofibers is going to deploy into her brain. The collar will be inside her mind. She will submit to me, and when the collar is in your mind, you will submit to me as well.”

Sofia stopped struggling. Her eyes went out of focus and one of her legs started twitching. She would have fallen over if it wasn’t for the rod connecting her neck to the priestess’s wrist. As Josephine predicted, the collar was deploying its nanofibers in her brain. She was completely out of it, apparently unaware of her surroundings as the collar did its work. It didn’t take long. In less than a minute the rod dissolved into a leash made of red light and Sofia took a stumbling step. Her eyes refocused.

“Oww,” she complained touching her throat.

“Listen to me, all of you,” Josephine said to the class, “I know you’ve heard this before, but it bears repeating. Always remember that consent is of paramount importance. It is the cornerstone on which the collar girl to master relationship is based. A collar girl can never be captured without consent, no exceptions.”

Her voice was strict and stern, but the warning was unnecessary. Everyone in the room knew that a collar girl couldn’t be captured or kept without consent. It was part of their lessons as trainers from day one.

“Do I have your consent?” Priestess Josephine asked Sofia.

“Of course, priestess, I acknowledge...” her voice trailed off as the collar activated before she finished her sentence. Her eyes went out of focus again. The collar was inside her mind, making the changes necessary to turn her into a collar girl.

It didn’t take long for Sofia’s eyes to come back into focus. She blinked a few times and then she looked at Priestess Josephine. Liam recognised the expression on her face. It was the same devotion that she gave him when he captured her. The priestess was now the most important person in Sofia’s world.

Sofia carelessly started stripping. She wasn’t trying to put on a show, it was just the efficient removal of clothing. She undid the drawstring on her pants, pulling them down along with her panties. She stepped out of her sandals while pulling her bikini top off over her head. Her earrings were next, pulling them out, and dropping them in the pile of clothing. She stood naked in front of the class, wearing nothing but the silver collar around her neck.

Sofia’s tanned skin contrasted nicely with the silver of the collar. Her long blonde hair hung down, covering the nipple of one of her full and perky breasts. She was gazing at the priestess with a devoted expression on her face. She would do anything for her master.

“Professor? Do we need to take our clothes off?” Evelynn asked.

“Nobody is going to force you to strip,” Brevifolia replied, “But once the collar goes on, you will want to be naked. It’s part of being a collar girl. Don’t worry, the collar will prevent you from feeling any shame.”

“That sucks,” Evelynn replied.

“It’s partially for your own safety. Your nudity helps to communicate that you’re vulnerable and in need of protection,” Professor Brevifolia explained.

“The other part is that worshippers of the goddess like to have naked women around. Nudity leads to sex and sex is one of the fun parts of the goddess’s domain,” Sandra commented. Professor Brevifolia smiled at her comment. He didn’t deny the truth of her words.

Sudden laughter from Priestess Josephine caught Liam’s attention. She had her tablet out, and she was laughing at what she was seeing on the screen. With an idle hand she was stroking Sofia’s shoulder while she worked her tablet. For Sofia’s part, she was focused on the priestess with an expression of pleasure on her face.

“Someone has a dirty sense of humor,” Josephine said, “Who gave you this name hun?”

“That was my boyfriend Liam,” Sofia said, pointing shamelessly at Liam. He gave them a little wave.

“Well then,” Josephine replied with a laugh, “I’ll have to find an equally fitting name for him when it’s his turn.”

“Dianthus Stigma follow!” Priestess Josephine ordered, using the collar girl name Liam had given her.

The red line of the leash reappeared, connecting her wrist with Sofia’s neck. Josephine started walking, leading Sofia around the track that circled the room. Sofia had her head bowed submissively as she was pulled by the leash. She tried to fight the leash for a moment, pulling back against it, but her struggles were hopeless. The collar kept moving despite her efforts, taking her neck with it, and forcing her to stumble along. She looked like a fresh collar pet being trained by its master.

Priestess Josephine stopped and spoke quietly to Sofia while stroking her arm. The rest of the class wasn’t really involved in this part. Most of them were watching, while others chatted nervously. As the priestess went back to walking Sofia around the track, Liam felt a hand on his elbow. He turned to see Sandra.

“How are you doing?” she asked.

“I’m okay, I guess. I never really thought about being captured. Capture devices were always something I would use, not something that was going to be used on me. It’s just not something I ever really worried about. This is going to take some adjusting.”

“If it makes you feel better,” Professor Brevifolia said, walking over to them, “The rest of the male students are being captured today as well. They’ll have a miserable time with a Tiresias stone or Salmacis infusion. Let me tell you, neither one is pleasant. The Tiresias stone makes you nauseous for hours before and after capture, while the infusion of Salmacis has a brutal hangover. Josephine and I are going to deal with them when we’re done here.”

“I know this came as a shock,” he continued, “I’m sorry about that. If I had known that you didn’t know, well, I would have told you earlier.”

“Professor Brevifolia,” Evelynn said, “I don’t want to be captured in front of Liam.”

“Me neither,” another girl said. There was a small group of them, nodding their heads.

“Yeah, I thought this was going to be a girls only thing. I can understand you being here professor, but does Liam have to be here. I mean, can’t he do this with the other men?”

The professor looked unsure of himself in the face of the united female students. For her part, Sandra rested her hand on Liam’s shoulder, quietly offering him her support.

“Ummm, this is a new situation,” Brevifolia said, “We don’t normally have someone like mister Smyth in our program. I felt it would be better if he was with the women.”

That was beginning to look like a mistake. Most of the class seemed to be agreeing with Evelynn. They didn’t want him here. To be honest, he didn’t particularly want to be with them either. There was an easy solution to the problem.

“I can go next, I guess. If that helps,” he said. Professor Brevifolia looked relieved. A few of the girls seemed happy with the idea.

“Yeah, that works,” Evelynn said.

Josephine brought Sofia back to the front of the class. She wasn’t fighting the leash anymore, following docilely behind the priestess with her head bowed submissively. On closer glance, Liam could see that the collar was tilted from the ‘follow’ command. Sofia had no choice but to bow her head. The collar was forcing her to do it.

Priestess Josephine still had her hand in the air, held at shoulder height. As she arrived in front of the class she lowered her arm to waist level. The leash went down with her hand and pulled the collar along with it. Sofia was dragged downwards. She tried to fight it, her legs and back shaking with strain, but it was hopeless. The collar dragged her downwards without showing any sign that her efforts were having an effect. She was left on her hands and knees with her head tilted so that she was staring at her own navel. Josephine leaned over her, stroking her back, and speaking quietly into her ear.

A few moments later, she started walking, and the leash began pulling Sofia along behind her. Josephine stayed close, keeping her new collar girl on a short leash. Sofia tried to pull against the leash, but it dragged her on her knees across the padded floor. After a few seconds of being dragged, she started crawling, apparently giving up on the fight. The entire time, her head was bowed with her hair hanging down and dragging on the floor. Her face was hidden by her hair.

“Dianthus Stigma, stop!” Priestess Josephine commanded.

A mote of light erupted from her wristband and raced towards Sofia’s throat. When it struck, she stopped moving. She was on her knees, with her head bowed, her face obscured by her hair. Josephine walked away from her, towards the table at the edge of the presentation area. Sofia tried to follow, her legs sliding on the ground, but she couldn’t move. The collar around her neck was stationary. It wouldn’t budge, and because it was a part of her neck, she couldn’t move either. The collar could hold a four-thousand-kilogram rhinoceros stationary, there was no hope for Sofia to be able to move it.

“Dianthus Stigma return!” Priestess Josephine commanded, pressing a button on her wristband.

There was a shocked intake of breath from one of the girls in the class. The mote of command raced down the leash from Josephine’s wrist towards Sofia’s throat. It struck her collar and she was momentarily outlined in light. Her body shattered into thousands of embers which were then sucked into the collar. A sprinkle of ash was all that was left of her. The collar flew through the air to the priestess’s waiting hand. She took off her wristband and attached it to the collar, putting it down on the table. There were nine more capture devices on the table. One for each of the remaining students.

“Wait!” Evelynn yelled, “Why did you put her in storage? I don’t want to go in storage!” Her voice went shrill as she yelled at the priestess. Her eyes were wide. She was panicking.

“Everybody goes into storage. It’s a mandatory part of the collar girl experience. This...” Priestess Josephine started explaining.

“No! Fuck no! I’m not going in storage. You can’t make me,” Evelynn interrupted.

“If you want your license...” Josephine started.

“Fuck that shit! A license isn’t worth dying over,” Evelynn yelled. She grabbed her bag and began storming towards the exit.

“Miss Grace, come back here!” Professor Brevifolia called out. He started to follow her, but Josephine held out her hand, stopping him.

“Let her go,” she said.

“She has spent the better part of two years learning to be a trainer. I can’t just let her throw that away,” Brevifolia said.

“You heard her,” Josephine replied, “She thinks that going into storage is the same as being killed. In the last two years how many times has she put collar pets in storage? How many times has she seen collar girls put in storage? In her mind, she’s killing her collar pets. She has no objections to other girls being killed, but when it’s her own neck on the line, she says no. Her morals are bent Joshua. I don’t want her as a licensed trainer, and I speak for the church.”

The door slammed as Evelynn exited the gym. An awkward silence descended on the room. Everyone was trying to avoid looking at the priestess and the collars on her table. A few of the women looked a little freaked out.

“Well, I guess I’m up next,” Liam said, breaking the silence.

Priestess Josephine smiled at him gratefully. He grabbed his backpack and went to join her in the center of the gym, but he noticed Sofia’s bag abandoned on the floor where she left it. He grabbed her bag as well and carried both to the table.

At a gesture from the priestess, Liam put his bag next to the table. He quickly gathered Sofia’s clothing off the floor and put them in her bag, taking the time to put her discarded earrings and necklace in the pouch where she liked to keep them. Looking at his own bag, he stopped for a moment to open it and clear space for his own clothing. Priestess Josephine cleared her throat, and a gentle breeze ruffled his hair. He realized he was stalling. He straightened and stepped towards her.

Priestess Josephine picked up one of the capture devices. With a twist of the handle, she extended it so that it was about a meter in length. A second twist and it was ready to go. The device suddenly looked very threatening. They never seemed threatening to him before, but now Liam couldn’t help but see it as a weapon.

“Are you nervous?” she asked.

“Yeah, a little,” he replied with a laugh. The laughter sounded forced, even to his own ears.

“This is your first time, so that’s normal,” she said, “Lets start out with some tidal breathing.”

“Ummm, what?”

“Take a deep breath in,” she said, “Imagine a wave washing across the beach. The wave is the air filling your lungs. Count to five in your head as you breathe in. Now, hold it for five seconds. Imagine the water on the beach. It’s in motion, changing directions, but constantly covering the same sand. Now, breathe out for five seconds. That’s the water flowing back into the ocean as the air leaves your lungs. Now, hold for five as the wet sand sits waiting for the next wave.”

Liam followed her instructions as she talked him through it, breathing and holding his breath when she told him to. It was actually working. He found himself calming down.

“Breathe in,” Josephine said.

Liam took another breath, imagining an ocean wave crashing across a beach. As he did, Josephine stepped towards him with the capture device. With a quick movement of her wrist, she lifted the device and the inside of the ring touched his throat. It took him a moment to realise what was happening and then the collar slammed shut. It gripped his throat in an iron grip. Instinctively, he tried to step back, but the collar was attached to her wrist. She had him by the throat.

He couldn’t breathe. The collar was incredibly tight. It was strangling him. He reached up and grabbed the rod connecting his throat with her wrist, but they were attached together. There was nothing either of them could do.
