Shirley's weekend at the hot springs was as restful as she could have hoped. She was a bit drowsy Saturday morning, and she had to deal with her clothes shrinking in the dryer, though the staff said they didn't. Why else would they feel so tight on her? The orange-haired girl, not noticing her changed, voluptuous form, dealt with having tighter clothes for the rest of the weekend, much to the appreciation of those who saw her happily walking around with a bounce in her step. There was a special gym class on Monday, so the girls left the hot springs Sunday afternoon, taking some souvenirs with them, and happy memories, planning to return the next chance they got. For some reason, Shirley felt like she had some enjoyable fun there, but she couldn't remember what. She could only remember that the girls were extra friendly with her, but they didn't act any differently. The thought passed as they reached the train station, where, for some reason, she felt strangely warm and her thighs rubbed together, as if she expected something to happen while she sat down.

Monday arrived, and with it, new uniforms for Shirley. They were a size bigger, not that she paid it much mind. To her, her clothes were just getting shrunk in the dryer, so these were her normal size. There's no way she could be getting any bigger. She was fit and active, and she had a balanced diet. Feeling rested and energetic, Shirley couldn't wait for gym class. She heard that they would be having special instructors for their physical fitness exam, coming from a place called Kuoh Town. Apparently they were famous there for their feats of strength and agility despite being the same age as Shirley and the other students at Ashford Academy. They were a team of six women, some with odd names. Regardless, she eagerly awaited the exam and meeting their special instructors all day, and had more of a bounce in her step as she raced to the locker room to change into her gym uniform.

Shirley met the apparent leader of the guest instructors, a lovely, if unusual, woman named Rias Gremory. She stood against the wall in the girl's locker room, making sure none of her students were doing anything they shouldn't. "Remember ladies, no underwear, that means no panties or bras. Got it?" The instructor said. Shirley thought that was unusual. Was there a safety reason not to wear underwear? Rias was truly beautiful though. She had long red hair that reached her thighs, piercing blue eyes, and a buxom figure that most women would kill to have. She wore her own academy uniform, a white dress shirt with a black ribbon around her neck, a short black cape on her shoulders with a matching corset, a magenta skirt, frilly white socks, and brown shoes. She seemed to be watching her students closely, and one could easily accuse her of ogling their naked, or near naked, bodies.

Shirley stripped herself naked and felt a bit vulnerable, especially as Rias looked at her and licked her lips. The orange-haired girl took out her white gym shirt and put it on. It felt somewhat tight, and it didn't cover her stomach, only reaching just two or three inches below her bust. She pulled it down in an effort to cover the rest of her, but she only succeeded in showing off her cleavage. Sighing in defeat, she let her shirt go and pulled on her red high-cut gym bloomers. She looked herself over and set everything right, then joined the rest of her class. Apparently the exams were gender specific, so the boys were on the other side of the school with the normal teachers. Shirley briefly wondered why the exams were so different than normal, but she decided that the teachers knew what they were doing and went along with it. She was still excited to see what the exam would be like.

"Okay class, get in lines. We're going to start by testing your grip strength." Rias announced, flanked on either side by her fellow guest instructors, all of whom wore the same uniform. A plastic bin was right in front of her, clearly not large enough for any equipment normally used during an exam. They were in the gym, standing in proper file lines. Shirley was confident in her strength and stamina since she was so active in the swim club, so she felt she could ace any test they could throw at her. Wait, stamina? Swim club? While her mind wandered to those two terms. Then she snapped back to reality by something she truly did not expect from her special gym class. Shirley's mouth hung open as the bin was opened by one of the guest teachers, a girl with short blue hair with a green fringe on the right side. She pulled out two double-sided dildos and showed them to the class. It seemed only Shirley was truly stunned by what they saw. "There is an odd number of students here, so the one without a partner will be teaming up with us one at a time." The girl announced in a calm tone of voice.

Shirley rushed to find a partner, but before she knew it, she was the odd girl out. "It seems you're the lucky girl." The blue-haired guest teacher said behind her, making the girl jump in surprise. She turned around and, as she expected, the girl held a dildo in her hand. "My name is Xenovia Quarta, and I will be assisting you with your grip exam." She introduced herself, her yellow eyes gazing into Shirley's green eyes. "O-Okay ... How do we do it?" The student asked, uncertainty filling her voice. A grip test with a dildo? A soft moan filled the air, then another, and another. The orange-haired girl looked around and saw something she could only dream of. The girls were paired off, with one on her knees in front of the other, using one hand to shove a thick dildo into her partner, and moving it back and forth.

"They seem to be doing well. I would expect nothing less of Ashford Academy." Xenovia observed. Shirley spun around, and saw a dildo being offered to her. "I will be checking your grip and pace. My standards will be higher than your fellow students, so please do not disappoint me." The guest teacher warned her. She lifted her skirt and pushed aside her plain white panties, exposing her flower to the baffled girl. Feeling as though she had no other choice, Shirley sunk to her knees and warily looked from the toy to the teacher's slit. "Um ... don't you need to be wet ... ?" Shirley quietly asked. Xenovia, looking down at her pupil, didn't bat an eye. "Yes, there must be lubrication. Either that toy, or I, must be wet. You may choose which one to start. Don't be afraid to use your mouth." The teacher clarified.

Shirley's mouth hung open again. Her choices were either to suck on the dildo, or eat her teacher out? Both would be in the gym class, surrounded by ... students doing the exact same thing with one another. Only her teacher was an active participant. The others were just waiting for their turn with the orange-haired student. Xenovia stood above her, looking down and holding her skirt up, waiting patiently for her student to make a move. Shirley took a deep breath and held the toy up and licked it, running her tongue from the middle of it to the top. For some reason, she knew what to do, almost like she had experience with phallic objects. She unconsciously began to sensually lick and suck on it, almost like she was trying to pleasure it. Her teachers took notice, but not even Xenovia, the teacher closest to her, said anything, not wanting to distract the clearly determined student from her work.

Satisfied that the toy was slick enough, Shirley, in her haze, leaned forward and dragged her tongue along Xenovia's flower, gaining a soft moan from the guest teacher. Clearly her student was putting in the extra effort for high marks. Shirley came to her senses when she pressed the toy against her own bloomer-covered slit. She leaned back and swallowed the sweet honey in her mouth, surprised that she enjoyed licking another girl, and enjoyed the taste. The blue-haired girl noticed Shirley's use of the toy and raised an eyebrow. "You may use it on yourself after class, but for now, you're to use it on your partner." She firmly corrected the girl, who hurriedly moved it away from herself. Refocusing her efforts, and trying to cope with the truly unusual situation she's found herself in, which feels oddly familiar, she brought the toy up to the guest teacher's slit and began to rub it, eliciting another soft moan from the blue-haired girl.

"Wait just a moment." Xenovia instructed, prompting Shirley to pull herself and the toy back. She watched the student teacher take off her skirt and panties and set them aside on the floor, giving the orange-haired girl more room to work. "You may continue now, miss ... ?" The teacher said, asking for her student's name. Shirley's mind wandered again as she got a better look at Xenovia's enticing flower. "Oh! Shirley Fenette, Miss Quarta." She gave her name to the half-naked girl. "You may refer to me as Xenovia. Given our current situation, being formal with one another would be unusual." The blue-haired teacher joked. Shirley gave a weak smile, then resumed her class work, bringing the toy up and gently rubbing it against the guest instructor, somehow delighting in sounds Xenovia made as pleasure began to run through her body. "You don't get extra points for making me cum, but I won't discourage your efforts either." The blue-haired teacher said in a breathy tone.

Shirley, feeling warm and in a haze again, gently pushed the toy into Xenovia, making the guest moan a bit louder as her flower was invaded by the slick toy. "Keep pushing it to the very end." She instructed, and her student did as told, pushing until she hit the base. The student was impressed that her teacher was still standing. Looking around, other girls were already on the floor, many of them half naked, or fully nude. It looked less like a gym class and more like group sex coming close to being a full orgy. Still, her lust-clouded mind assured her that Ashford Academy had planned this properly. She saw Milly and Kallen paired up, and if Milly was there as an active participant, thrusting her toy into Kallen, who leaned against the wall on the verge of a powerful orgasm. She returned her attention to her teacher, who was already blushing, and started her grip test.

Shirley firmly gripped the toy and pulled it out half way, then pushed it back in, quickly finding a pace that would work best. Xenovia's nectar was already spilling out, proving how good of a job her student was doing. She moaned louder and almost ripped her buttons pulling off the top of her uniform, leaving her naked except her socks and shoes. Her fellow guest teachers were both surprised and happy to see the response to the orange-haired girl, and eagerly awaited their own turns to teach her and gauge her fitness. Xenovia roughly grabbed her breasts, kneading and rolling them in her hands, as Shirley picked up her pace, almost hammering at the blue-haired teacher's slit. She began to twist it with each thrust, and a part of her wished it had a vibrating function. Not that it would help test her grip strength or dexterity in any way.

Shirley saw just how good Xenovia was feeling, and it made her feel hotter, and her breathing became more labored. She looked around and saw how much fun everyone else was having with the exam. It wasn't a normal exam by any means, but she wanted to have fun too. The orange-haired girl pulled her shirt up and over her large breasts and began to rub herself just as her teacher was, following her example. See, she was learning something, so it wasn't unusual at all. Xenovia's moans became louder and quicker, and something told her pupil that she would cum soon, so the toy was thrust into her faster and harder. Shirley begrudgingly moved her hand from her chest to the guest teacher and began to tease the blue-haired girl's stiff clit. Though she wouldn't get extra credit for her efforts, her teachers most certainly approved of her initiative, especially Xenovia, who quickly achieved a body-trembling climax.

A damp spot formed on the crotch of Shirley's bloomers, making it clear how aroused the fitness exam was for her. Who wouldn't be, watching a sexy student teacher like Xenovia cum right in front of her. She was still on her feet, despite how weak her knees felt. "Top ... marks, Shirley... Very well done." She graded her student, and shuddered as the toy was pulled free of her slit. Xenovia got to cum, but Shirley was still in desperate need of relief. Looking around again, it was clear that both girls in the other teams were able to cum. Feeling left out, Shirley decided to use the double-ended dildo on herself. She brought the end that was previously inside her teacher against her covered flower, but she was caught. Xenovia knelt down and quickly grabbed it. "I said that you may use this after class" She reminded the thoroughly aroused girl. Seeing her desperation, the guest teacher relented. "But if you're so desperate, perhaps I can use it on you during the next phase of the examination. You'll be using a different one with Rias." A fair compromise, and the student was curious about what the next phase would be like.

"Okay class, settle down now. We took down your scores, and as we expected of the Ashford Academy girls, you all excelled." Rias announced to the class, completely naked. The other guests were naked too, baring everything to the class. Shirley stood up with Xenovia and watched the red-haired girl announce the next step, somehow unfazed by the nudity. Everyone was naked by that point anyway, and surprisingly, Shirley was completely comfortable with it. "For your next test, we'll be checking your upper arm strength and lung capacity. For the mermaids of the class, this will be no problem for you." The lead instructor told them. She bent down, obviously flashing her ass and flower to the entire class, even swaying her hips idly as she searched through the plastic bin for the next tool. To their surprise and delight, it was a double-sided strap-on dildo. The other teams playfully argued among themselves about who would wear it first.

Shirley was still on the surprised phase. Upper body strength and lung capacity? What did those have to do with a strap-on dildo? A number of chairs were brought out, and the girls who won their arguments or janken matches eagerly put on their new toys and sat down on the chairs while their partners knelt between their legs and used their chests, sandwiching the dildos in the valley between their breasts, and rubbed those toys while licking and sucking on them with their mouths. Watching the erotic scene unfold, Shirley was startled by Rias' approach, acting as Shirley's own partner for the exercise. "Are you ready to go, cutie?" The red-haired teacher asked, giving a playful wink. She briefly tugged on Shirley's shirt, giving her a not-so-subtle hint about her clothes. The student dumbly nodded, not at all mentally prepared. "Great!" Her teacher cheered with a bright smile on her lips.

Rias had already put on her toy, so she sat down on the chair and spread her legs. "I saw how well you did in the first phase, so I expect good results." The teacher informed her student. Shirley nodded, taking off her clothes and tossing them aside, and then she sank back down to her knees. Rias watched Xenovia do the same, and was curious. "Are you joining?" She asked. The blue-haired girl smiled. "Shirley needs relief, and I promised to provide it." A simple answer that made the orange-haired student caught in the middle blush even harder. Rias grinned. "Oh~ Well, you can't keep such a cute girl waiting." The red-haired teacher encouraged it. Then, a fun thought came to mind. She turned to her student and continued to grin. "We can also make this a part of the test. Successfully complete this phase of the exam while she plays with you, and you'll get extra points. However, if you fail, we'll deduct extra points." She warned, wagging her finger. She knew the look in her student's eyes, there was no way the girl would refuse the wager.

Shirley felt compelled to go between Rias' legs and, like her friends around her, wrap her large breasts around her instructor's toy. "Ahh~ These feel amazing. There's no way you're single." The red-haired teacher praised her student, caressing the ample bosom that rested on her lap. Shirley appeared to be shy, which was silly given the situation. "I-I'm single." She admitted. Both Rias and Xenovia were surprised. "Clearly your peers are blind, or they lack taste." The blue haired girl stated. Her red-haired friend was in complete agreement. "Clearly. We may just take you with us when we leave. Fuoh Academy knows a good girl when they see one." She offered, teasing the girl's nipples between her fingers, making her student whimper. "We can talk transfers later. For now, you don't want to fall behind your friends, do you? Let's get started."

Shirley carried out the test, using her breasts to rub the plastic toy, feeling a pleasant friction against her skin that made her moan as she sucked on the toy. Her head bobbed up and down on the toy, pulling and pushing it into Rias. Her teacher sat back and moaned, loving her job. Xenovia sat on her legs beside Shirley and reached between the girl's thighs from behind, placing her hand delicately on her orange-haired student's warm and wet flower. Shirley briefly stopped, distracted by the new contact. The blue-haired teacher would have none of that. "If you stop, so will I." She quietly warned, prompting her student to continue. Xenovia began to firmly rub her, taking note of the stifled moans the girl made. She really was desperate, and her teacher would have fun with that.

Rias wanted to indulge herself further in her lessons, and possessed of great power that not even the Britannians knew of, cast as spell on not only her toy, but everyone else's, granting them the property of transmitting sensations from the toy to the wearer, so Rias felt as though she had a real shaft that Shirley was so thoroughly pleasuring. "Keep it up. At this rate, you're going to get high marks, and maybe even a special award." The red-haired instructor praised her student. Xenovia gave her friend a dull look. Regardless of their intent, they were still meant to be teaching a class and not just having sex with the students. She nevertheless continued to tease and play with Shirley's body, rubbing her slit, but not enough to get the overwhelmed girl off just yet.

Shirley's mind was clouded in lust, allowing her only to moan and continue her test with the sexy redhead. She had long abandoned the notion that anything was wrong. It was almost like sex ed, only with active participation. She whined, feeling two lithe digits push their way past her lower lips, and her body reacted, finally getting what it so desperately needed. Her hips squirmed as Xenovia's fingers began to work in and out of the girl's flower. Shirley moved against those fingers, trying to take them deeper. Rias noticed this and gave a knowing look to Xenovia, telling her friend to let loose and teach their precious student how real grip strength works. The blue-haired guest removed her fingers, making her pupil whine in frustration, only to be surprised when she felt the toy she used earlier rub along her slit.

Xenovia used the opposite end of the toy and teased it against Shirley's slit, then gently pushed it inside. It easily slipped in the wet hole, much to her own delight. "You're clearly an ace student, Shirley. Perhaps you could be our assistant at the end of the test." The blue-haired teacher suggested. Rias pretended to consider it. "You're right. We will need an assistant at the end of the exam. If you do a good job, that will be you, cutie~" The redhead promised. Shirley barely heard them, feeling as though she were drowning in arousal. She continued to move her chest, moving them up and down while she kept the tip of the toy in her mouth, circling her tongue around it. Rias shivered in pleasure, mentally giving her points, though the test didn't make mention of style or skill. The girl stopped that and pinned the toy between her breasts, resting them on her teacher's lap, and began to suck on the toy again, taking it down her throat as far as her large chest would allow. Again, her teacher gave her points for style, disregarding what minor rules existed for their special test.

Seeing their student really get into it, Xenovia pushed her toy deep into the girl, touching her base with it. Her other hand cupped the orange-haired student's chest. Perhaps it was interference, but neither Rias nor Shirley minded. The blue-haired girl began to thrust her toy in and out of the needy girl as she teased her nipple at the same time. To run a bit more interference, she leaned closer and gently licked the girl's earlobe, making her shiver and whine, but not stopping her. "That's it. Show is your strength and lung capacity. I want you to be the lucky girl to help us at the end." She whispered directly into the girl's ear, encouraging her to keep moving her head and breasts.

Xenovia moved her hand and head away from Shirley, but kept her toy thrusting into the girl, who continued to give voice to the pleasure and ecstasy she felt. Rias was moaning as well, absolutely happy with her student's efforts. Xenovia decided to reach up and grab one of her friend's breasts, rolling and kneading it in her hand. Rias whined, and grabbed her other breast. "Oh you~ I'm going to make you pay for that later." She teased, sticking out her tongue. Xenovia grinned, wanting exactly that. She kept thrusting the toy deep into Shirley, giving her the same treatment she received earlier. In her lust-clouded mind, Shirley heard Rias moan louder, and could tell she would be cumming soon. Already so close to her own climax, she picked up her pace, hoping to make her teacher cum around the time she herself came, if only to save herself from being limp and useless, and failing that phase of the test.

Shirley got her wish, feeling relief in so many different ways. Her loud moan was stifled by Rias' toy, but her teacher was heard loud and clear. The redhead shoved her student's head down on her toy, hoping to feel more of her tight and wet throat. Shirley didn't have much strength to fight back, her body writhing in bliss. Xenovia kept pumping that delightful toy into her, dragging her climax out as long as possible. "You kept going until the end. We'll definitely need you for the final test." She praised the girl. Rias nodded in agreement, gently stroking those flowing orange locks. "You pass, of course. Perfect marks for our top student." Shirley pulled her head up and took a couple of deep and relaxing breaths, still trembling as Xenovia pulled the toy out of her. "T-Thank you, Miss Rias." She managed to speak, feeling weak and overwhelmed. The red-haired teacher giggled and leaned down to plant a kiss on her forehead, while planning to kiss her elsewhere later on. Xenovia got closer, giving her a gentle kiss to her cheek.

Rias stood up and gave a passing wink to Shirley as she walked back to the front of the class, leaving the orange-haired girl to catch her breath, sitting on her legs, hunched forward with her hands on her knees. "Okay ladies, great job~! The next phase is going to be squats." The redhead announced. Shirley was surprised. That ... sounded like ordinary athletics. The guest instructor continued. "To all the lucky ladies still wearing their strap-ons, lay down on the ground. Partners, straddle their hips and take that toy inside you, then perform your squats. We'll gauge how many you can do before you cum, so try to aim for a high number!" Shirley sighed, having expected some twist. Rias left her with the strap-on, and Xenovia had returned to the rest of the guest teachers, so the orange-haired girl wondered who her partner would be.

Two girls walked towards her. Shirley wondered why they were cosplaying. One had long black hair, cat ears and two tails, and the one beside her had white hair, cat ears, and three tails, and they both had gold-colored eyes. They were both very buxom girls, easily on par with Rias' figure. They also both wore double-sided strap-on dildos. "Hello~ My name is Kuroka, and this is my younger sister, Koneko. We'll be your partners for this phase. We saw how well you did with Rias and Xenovia, and we thought you could inspire the rest of the class by having two partners for this." The black-haired catgirl introduced herself. Before Shirley could ask any of her questions, Kuroka set aside the chair Rias brought and laid on the floor. Koneko joined her, laying opposite her and interlacing their legs, pushing their lower halves together and bringing their strap-ons closer to one another. It became readily apparent what they wanted Shirley to do: she was meant to squat over both of them at once. Seeing no other way, she rose to her feet and stood over them both. She couldn't really complain, could she? They were her teachers. It's not because she wanted to feel both of her holes filled at once. This was a fitness test, not sex.

Shirley lowered herself down, and the sisters aimed their toys right at her ass and flower, allowing her to simply move down. She groaned, feeling those plastic shafts pierce her holes. She persisted, feeling a sense of nostalgia and euphoria. "Come on. Take them to the base. The squats don't count if you don't lower yourself entirely." Kuroka informed her. A part of Shirley told her that she would have done it anyway even without the warning. She wanted to be filled by the sexy girls, and her voice gave it away just as the cat sisters were hilted inside of her, moaning in unison as they felt what the toys felt. "Ahhh ... I should have gone before Rias. I bet your breasts would have felt nice~" Kuroka cooed. Koneko lightly slapped Shirley's ass. "She still feels good here. Come on, start your squats. The other students are looking to you to be inspired." The younger sister told her.

Shirley looked around and saw that the others were looking at her, surprised that she was with two partners instead of one. Even her roommate Sophie looked at her with interest. In her lust-addled mind, she thought they were inspired by her, and wanted to really give them someone to look up to. She was an ace in the swim club, according to her coach. The orange-haired girl locked her fingers behind her head and began her squats, raising up and letting out a soft moan, then slamming herself back down, making all three girls raise their voices. Rias, as much as she enjoyed the performance, called for the rest of the class not to slack off and to keep going. Some of the students ran up to get more strap-ons so they could go with two partners like Shirley. Even Kallen and Milly used two with Miya when she did her squats. Feeling emboldened by her fellow students, and trying to set a good example, she began to move faster, moaning louder and faster as mind-blowing pleasure shot through her body.

The sight of Shirley's large chest bouncing with each squat proved to be too much for one of the guest instructors. Akeno approached Shirley, wearing a strap-on of her own. Akeno was a beautiful young woman with a voluptuous figure, very long black hair that reached all the way down to her legs, and kept in place with an orange ribbon, and violet eyes. "Allow me to help you, Shirley." The black-haired girl said, smirking. Standing in front of the orange-haired student, with Kuroka between her legs, she grabbed Shirley's large chest in her hands and pushed her toy between them, and Shirley's own squats provided the stimulation she needed. She sighed in bliss, watching the girl bounce up and down with a face reflecting nothing but lust. It was truly obscene, and Akeno loved watching her.

"Akeno, couldn't you have waited your turn?" Koneko asked in a flat tone, her hands resting on Shirley's hips. Akeno provided no answer, since she couldn't excuse her presence beyond simple impatience. Shirley's mouth was open and her tongue was out, clearly not concerned with appearance, so she took advantage and bent the girl's head down while aiming her toy properly, making the girl suck on her whenever she lowered herself down. Shirley was lost in a sea of lust, so she didn't complain, allowing Akeno to do as she wished during her test. With her flower and ass filled and her chest and mouth being used, who could blame her for being so overwhelmed? The other students watching her and taking their cues most certainly didn't. Rias, watching her three friends have their fun with Shirley, mentally added points for something not part of the curriculum.

Koneko and Kuroka fought the urge to move their hips on their own, having no excuse that would justify interfering with Shirley's squats. Akeno had no excuse either, but she was only using their orange-haired student's chest and mouth to get herself off, and it didn't impede the girl's motions. Rather, the girl seemed more eager to move, if not to have those toys gouging out her insides, than for a third toy to rub between her breasts, and to suck on it at the same time. She had a similar experience with Rias, and found that she enjoyed it, especially if something else was going inside her. Her body trembled with excitement, and her mind slipped further away as another orgasm built up inside her. Her lust-addled mind told her that her hands-on teachers were close as well. They were moaning loudly, and Akeno's hold on her chest became firmer, using her breasts to rub the toy slick with her own saliva.

Shirley barely uttered a sound as her orgasm crashed through her body. She slammed her hips back down and writhed in place as she rode out another climax. Her sexy teachers followed suit shortly afterward, enjoying their own orgasms. "Rias was right, you are an ace student." Akeno praised the girl, begrudgingly releasing her chest and pulling the dildo from her mouth. Shirley seemed to have come back to her senses as she let out a whimper, trying to contain her voice. Kuroka slowly sat up and smiled. "Top marks, Shirley. You performed very well." The black-haired cat girl graded the student. Koneko sat up as well and agreed. "You're an inspiration to your fellow students." It was genuine praise, but for something clearly obscene, and their student appreciated it, struggling to find words to express her feelings.

Rias took the front of the class again. "Okay~! Great job, students. Now everyone stand up. If you can, that is~" The red-haired teacher announced. Shirley lowered her arms and struggled to stand up, and found assistance from Akeno, who offered her a hand. Feeling weak, she slowly stood up, groaning as her holes were left empty of the toys. The black-haired girl wrapped her arm around her student's hips. "Good work so far. Take a deep breath, we'll need you for the final round." Shirley already felt tired. She came twice and in a public setting, which seemed strangely familiar. "What is the-?" She began, but was cut off by Rias. "Now, to wrap this exam up properly, you'll be combining the first three phases in one. We'll test your grip strength, your upper-body strength and lung capacity, while you perform squats." She announced, receiving a number of cheers from the students, who had since formed larger groups to take their tests.

Shirley was left stunned again. Rias' last test, and their words about 'helping the teachers' swirled in her mind. Wait, there were six teachers, and Shirley was supposed to help them all? Rias and Xenovia approached Shirley, both wearing strap-ons, with the last guest teacher, also wearing a strap-on and nothing else. "Okay Asia, everyone else got their turn with-I mean helped Shirley, so you can choose which test you want to help her with." Rias offered to her friend. Asia was just as sexy as the other girls, with long blonde hair and green eyes. Her bust size wasn't as big as the others, but it didn't much matter. She thought a moment. "I think I would like to help with squatting." The blonde teacher decided, happily smiling. With that settled, the other teachers quietly decided how they would 'help' Shirley pass the final phase, but more and more, it sounded like they just wanted to have group sex with her.

A more clear-minded Shirley was obviously nervous, and eyed the exit with thoughts of escape. However, two things prevented any sort of reprieve. First, were the encouraging looks from her friends, who took to their test with excitement, pairing up in groups to happily show off their strength and stamina. Second would be Xenovia's grip on her wrist, pulling her over to Asia. Like the cat sisters Kuroka and Koneko, Rias and Asia laid on the ground, with Rias aiming for her slit, and Asia aiming for her ass. Well, she had to complete the test, didn't she? Despite concerns, she was a bit more eager than she let on to squat down over two thick dildos, stabbing her two holes again. Rias, doing away with the charade of 'testing her strength', bucked her hips upward, hilting her toy deep inside her orange-haired student.

Stunned, Shirley was forced on her knees as both Rias' and Asia's dildos were stabbed inside her at once. Noticing that the girl was trying to get back up, Akeno stood near her side, turned the girl's head to face her, and casually shoved her toy back into Shirley's mouth. "You're getting perfect scores for the test anyway, so just relax and enjoy." She stated, grinning. Kuroka appeared beside her, right in front of Shirley, and grabbed the orange-haired girl's chest, forming a valley for her plastic shaft to thrust between. "I knew it. Her chest is perfect." The black-haired catgirl cooed. Rias cleared her throat and poked her friend's ass cheek, clearly proud of her own bust. The catgirl sighed and relented. "Yes, you still have a pair of the Chosen Heavenly Breasts, just like I do. I'm just saying, her breasts are just as divine."

While Rias took her slit, and Asia took her ass, Shirley's mouth was occupied by Akeno, and her chest by Kuroka. Xenovia and Koneko stood on either side of the student. Shirley, trying to keep to some part of her fitness exam, wrapped her fingers around them and began to move them back and forth, pumping her hands to prove, among other things, that she had a good grip and a pleasant touch. Just like that, she allowed herself to be carried by the flow, feeling full. Her holes were mercilessly pounded by her sexy teachers, her chest was rubbed against by another, and her hands were busy with two other toys. While her teachers could moan and join a song of lust that rang through the gym, her voice was stifled by Akeno's toy.

Rias and Asia found a good pattern as they thrust from below, rocking against Shirley's body, moving her up and down with each movement. They all independently decided that they chose the right girl to be their 'teacher's aide'. "Ahh ... I want her mouth next." Koneko declared while she enjoyed the girl's hand. They decided among themselves who would go where the next round, completely discarding any cover of it being a 'test', and Shirley, their target, barely paid attention. She felt a grand climax building up, and it shoved any other thought out of her mind. They knew it of course, and it was endearing to them. She was a sexy, slutty girl, and she made their trip to Ashford Academy worthwhile. The girls moved harder and faster against their favorite student as their own orgasms reached their peaks.

The guest teachers cried out in pure bliss and ecstasy as they climaxed, but their student's voice was much more muted. Asia slowly sat up and caught Shirley as she leaned back, releasing Koneko's and Xenovia's toys. Asia affectionately embraced the girl as she caught her breath. The blonde teacher rubbed her breasts against Shirley's back, keeping her stimulated. Rias ducked underneath Kuroka and was the first to kiss Shirley's lips, briefly making out with the lust-addled girl. "Perfect score so far, but don't give up yet. This test goes until you can't cum anymore~" She informed the girl, who was filled with arousal and concern. Of course, who was she to question her teachers? "Okay." She said, finding some renewed vigor.

Their physical fitness exam went longer than the boy's did, lasting well over an hour. "Okay class~! You all pass! Perfect scores!" Rias announced, to the tired cheers of her pupils. Her friends flanked her as before, still naked except the wet strap-ons. Shirley joined them, looking tired, but satisfied. "And let's thank Shirley for being a good inspiration! I saw you all take on the more challenging versions of the test, and you should all be proud." Rias added, and the class briefly applauded their ace student. The redhead casually strolled over to her teacher's assistant and pulled the girl in for a deep and passionate kiss. "You were great, Shirley. Don't forget about us after we leave~" She whispered, staring deep into Shirley's eyes.

A blaring sound filled Shirley's ears. She found herself lying in bed, confused. She sat upright and turned to her clock, quickly shutting off the alarm. It was Tuesday, and for some reason, she couldn't remember much about Monday. Didn't she have a fitness test? She barely remembered performing well, and getting praised for her efforts. She also remembered being really tired and wet, but that went hand in hand with gym anyway. Shirley threw off her blanket and got out of bed, stretching herself. Sophie, her roommate, went to greet her, dressed in a long white t-shirt as her pajamas. She stopped and saw what Shirley was wearing, a red t-shirt with Kuoh Academy's name on it. The shirt itself was tight on Shirley's large bust, and it rode high, showing her stomach and the lower half of her chest, especially as she was stretching. Her stiff nipples very obviously poked against the thin shirt. The orange-haired girl was also wearing a skimpy thong that did little to cover her, showing the outline of her flower, and from behind, her ass would be on clear display. It was an odd wardrobe choice for the girl. "Good morning, Sophie!" She greeted her friend, standing straight and heaving a sigh after her stretch. The purple-haired roommate blushed and stammered. "G-Good morning. Did you sleep well?" She asked, confused, and somewhat aroused by the sight. Shirley smiled brightly and nodded. "Yep! I feel like I worked up a real sweat yesterday and slept all of my exhaustion away."
