Hinata slipped out of bed gingerly and padded across to the room's one and only full length mirror. There was hardly enough space to swing a cat in the tiny dorm room she shared with her friend, Akira; but she was grateful for what she had. She lifted the simple white nightdress off over her head and threw it on the only chair in the room. Thumbs pushed the white cotton panties off her hips and mons; and because they were tight, she had to work them all the way down to her ankles.

Bags and boxes littered the floor, giving the appearance of total chaos, but they had always liked it that way. The teenager was sad though, having packed her possessions the previous night, but she and Akira were marching on to pastures new and life had to go on regardless.

A week earlier the high school's headmistress had praised her, along with Akira and 30 other students for being the highest achieving girls of their year. They were the elite learners and as a reward were offered places at the Shiraoka International Finishing Academy, (SIFA). Her roommate was excited about the opportunity, but she wasn't so sure.

Since the sixth grade, she had wanted to be an engineer, so immediately threw herself at the subject when she started at Joyama High school. An English couple who were honorary board members of the Charity for Oversea Orphans & Migrants, (COOM), had been her guardians for as long as she could remember. The charity owned Joyama High and Shiraoka Academy, so it was almost a given that she would end up at the academy. The years had flown by and because she was a good student, she gained all her qualifications a year ahead of time.

The school recommended that she complete a one year extension course to take her up to 18. Her guardians, Lord and Lady Hollins were very enthusiastic about her continuing on to the academy and influenced her decision greatly. They were all the family she had, having been abandoned at birth outside a hospital emergency room.

There were hardly any details about the Shiraoka program, but because Akira was also keen, and she was more than her best friend, Hinata agreed to enter too. The extension course turned out to be a series of outward bound adventures in which the leaders pitted one team against another. She travelled the world for weeks at a time, climbing mountains, tackling white water rapids, tracking wild animals, crossing glaciers, along with dozens of other activities.

Hinata was also taught to hunt animals and humans, hand to hand fighting, fire guns and shoot arrows. She began the course as a timid, 17 year old Hermione-like swot and finished it feeling like the lead character out of The Hunger Games. When the group returned to Joyama a week earlier, the principal at Joyama High explained that they were going to be taken to the academy for a week's induction before they started their first year there.

It came as a surprise to Hinata that she was being expected to continue with her education without a break. But that paled into insignificance when she went for what she thought was a medical to see how her fitness had developed during the year's extension course. She had to sit in the dreaded gynaecological chair and submit to being anesthetized.

Laser hair removal, Tattooing, piercing and vaginal penetration followed, all of which came as a total shock to the youngster. The school nurse hadn't warned her, nor had the school, and it had taken her several days to get used to the modifications to her body.

Studying her svelte figure in the mirror, she could see that her arms and legs were more muscular, and that her breasts and stomach, firmer. Tattooed on her smooth mons, where once she had a shock of black pubes, were the half inch high letters, 'SIFA', in bold blue capitals. It was one of the requirements for continuing on the course, along with the so called vaginal stopper and piercings.

An oval shaped chromium ring had been inserted into deep piercings either side of her vaginal portal. The lower part of the ring treaded through an eye on the top of the stopper, which felt suspiciously like a realistically shaped dildo. She hadn't seen the chastity devise before she was sedated, so had to imagine what the object buried deep inside her looked like.

Hinata reached down and ran her fingertips across the smooth tattoo, before following the line of her pudendal ridge, into her cleft and to the top of the chunky ring. The ring and stopper were an abomination and an outright infringement of her civil rights, but after careful consideration she had decided to accept a period of chastity and do the course, even though the school kept her in the dark about what was involved.

Akira had reminded her of the long term benefits to their careers, but it was the financial inducements that had finally persuaded her to commit at least two years of her life to the finishing academy. She had signed those years of her life away and hoped that she didn't live to regret her actions.

Both she and Akira were in the same boat, in that they relied on the charity for everything - school fees, clothes, food, etc. So the 320K yen they would receive at the beginning of each year of the course, would swell their pitiful savings and give them a nest egg for after the course was over. The decision was made easier by other factors. Akira was dead keen to do it and every girl that had spent three years at SIFA had gone on to be hugely successful.

Hinata returned to the bunkbed and whisked the covers off her naked friend. Akira was lying at her eye level, on her front, and pretending to be asleep. She raised her hand and brought it down hard on the girl's spectacular peach.

SLAP! "Get up you lazy bitch. Time we were joining the others." Her friend was more confident about her body image and always slept in the nude.

"Owww! There's no need for that!" she cried, rolling away from the edge, onto her side.

"Get up. The damn alarm is going to go off in 25 minutes at 10 o'clock."

"If you suck my pussy, I'll get up."

"In your dreams Aki. Hurry if you want some breakfast, the coach leaves at 11 o'clock."

Her friend twisted her legs toward her and then suddenly threw them out to catch Hinata's head in a scissor movement. "Got ya," she cried, triumphantly. "And don't call me Aki!"

Hinata found herself staring at the well-defined gash of her friend's delightful pussy, but the girl was vulnerable lying within easy reach. So, grabbing her friend's waist, Hinata began tickling her. Akira immediately started squirming and giggling, but she couldn't get her to release her neck.

"Alright," she shouted as Akira drew her closer so that her chin was up against her friend's perineum. "Enough. Let me go!"

"One kiss, babe and I'll free you."

Hinata was desperate to avoid being shocked by her dildo again, so started lapping her friend's pussy. She had performed cunnilingus on Akira a couple of times, when she was drunk, but received it many more times; because her roommate was that way inclined.

She started by teasing around her portal, which contained the stub end of the stopper. The eyelet through which the ring was threaded projected about half an inch and the five day old wounds left by the piercing needle had healed nicely. They didn't quite understand what kept the two pieces of the oval ring together, but one of the girls thought it had something to do with its temperature and chromium being the hardest metal on the planet.

After lapping the full length of her inners and ridge a few times, Akira released her and sat up. "We must do this every morning," she said cheekily, running her fingers through Hinata's hair.

"We might not be in the same room or dorm at the academy," she retorted.

Akira jumped down and stepped forward, so that their nipples were touching each other's breasts. "Let's promise to look out for each other, babe."

Her friend was an inch taller - 5'6" - but had an almost identical body shape. They would both grace any porn site and could make a quick fortune if they were that way inclined. In fact they were propositioned while having a drink in a nightclub by the owner of an entertainment company; but told him to sling his hook. They were both proud virgins, so it had come as a huge shock when the doctor had invaded and filled their virginal quims.

Hinata was pretty sure that her friend was more attractive, for she was the one that the boys looked at first; but Hinata didn't mind one bit. They both had brown eyes and high cheekbones, but her face was a little longer and had a well-defined chin. Their black hair was cut in the prescribed manner, shoulder length and with an almost square fringe. They could be sisters, but definitely not twins.

Once Akira had collected her box from the corner and dumped the new uniform on her bed, she followed suit and turfed hers out. They had examined the outfits the previous night and after looking at the short skirts and sailor style blouses thought that they either had the wrong boxes, or someone was playing a joke on them. However, when they discovered the academy crests on the sports clothing, cardigan and jacket they accepted they were going to have to wear them.

Hinata began with the panties and short blue pleated skirt. She had been wearing her skirts knee length and her panties black or blue for three or four years, so it felt strange donning short skirts with white underwear. She might have worn them to a party for a laugh, but at 18 she felt a little ridiculous. However, after watching her friend pull on the tight panties and shimmying them over her pert butt, Hinata detected a thrill in the pit of her stomach, which surprised her.

There was no bra with the uniform and the 'V' neck blouse was cut deeply, but once the blue sailor style collar and red bow were in place, the top half of the uniform was half decent. White knee length socks and black strap over shoes completed the slightly ridiculous retro outfit, which she hoped she would quickly get used to.

Once they had loaded their bags onto a trolley left for them in the corridor, they checked that they hadn't left anything behind and then set off for the dining hall. The halls were deserted, because most of the students had been on holiday for 4 weeks. They and the 30 other girls going to the Shiraoka Academy weren't so lucky and were having to continue their education without a break.

They had almost reached their destination when both girls stopped dead in their tracks. Their dildos were vibrating, signalling that it was 10 o'clock and they were late. It was an alarming sensation, because it was inside them and beyond their control, however it wasn't an awful feeling and it soon passed. The teenager was sure that if it continued for any length of time she would begin to enjoy it, but alas it only lasted for a few seconds. TWUMP!

"Uhhhh!" they both cried out simultaneously when they received a jolt from their silicone invaders. The sensation tore up into their stomachs making them double up in pain.

"What the fuck?" Akira exclaimed as she slowly straightened up.

Hinata felt a few drops of urine leak into her panties, but she managed to stop the flow. "Fucking hell," she retorted. "I wasn't expecting that!"

She quickly got the trolley moving again and raced down the corridor with Akira hurrying along behind her. A student, pushing a similar trolley, emerged from another corridor and joined them as they rushed toward the hall. The expression on the girl's face and her uncomfortable posture revealed everything Hinata needed to know. Their teachers had a way of punishing them from a distance which suggested that their stay at the Shiraoka Girl's Academy was going to be anything but fun!
