The first Friday of the school year...

Sera stood before the group who were about to undergo the training that took place in the strange world that was in her backyard. Hanging from the strings in her outstretched hand were gemstones shaped like finger-sized hexagonal prisms with pointy ends. She passed them around by throwing them directly at them.

"What're these for?" Rock asked as he caught his gemstone. He stared at the red ruby gemstone he was given, then looked to see what everyone else got.

"These precious little things called tuning stones," Sera replied with a grin on her face. She paused for a second, then in an unconcerned voice said, "I'm sorry Spike. Did I throw too hard?"

Everyone else sweat dropped.

"Ow..." Spike moaned as he sat up after getting hit in the forehead by the blue sapphire prism that was now in his hand. Once he stood back up, he looked at his gemstone before noticing that Monica had the same one. Even though a small stream of smoke was coming from his forehead, he replied to Sera, "I'm fine. It just slipped, that's all."

"....." Tim had a yellow topaz gemstone, which he decided to wear around his neck.

"These tuning stones glow any time they're within their respective elements," Sera explained as she produced a third blue tuning stone to demonstrate. She threw the gemstone into the pool and as soon as it was submerged, it started glowing as brightly as a glowstick. Before it was out of reach, she knelt down and pulled it out of the water. As soon as she did, the gemstone stopped glowing. "It reacted to the mana of the pool's water, you see. The heavier the mana concentration, the brighter it'll glow. Of course, these gemstones don't just react to mana."

To demonstrate what she meant, she placed the blue gemstone around her neck and held it up for everyone to see. Once she had everyone's attention, which took a while to get from a certain half-dog, she released enough blue ki from her hand for normal people to see and for the gemstone to become enveloped in it. Almost instantly, the gemstone glowed so bright that everyone except Sera had to look away at once. A couple seconds later, both Sera's hand and the gemstone stopped glowing.

"It didn't glow that bright when it was in the water," Rock remarked as soon as it was safe to look again.

"Shiny! Do it again!" Trent exclaimed excitedly as he moved about rapidly to examine Sera's gemstone from all possible angles.

"It'd take years before any of you could reach this level," Sera smirked as she took off the gemstone and threw it over the cliff. Trent immediately went after it by diving off the cliff and disappeared from view.

"Uh... is he going to be alright?" Spike asked as he watched his hyperactive friend dive off the cliff.

"The aura produced by your ki is as unique as your DNA, but you can tune it so that its properties matches something else, like water," Sera continued her explanation. "The best way to do that is by being in an environment where you're surrounded by the right kind of mana. That's why we're here. There are a select few locations that are perfect for this kind of training. You'll be staying at those locations for ten hours per day for the next three days in groups of two. I've already decided on the pairs."

"Oh hell no!" Rock sharply replied as he held up his red gemstone. "Unless red means tomato patches, I ain't spending three days in some scorching hot desert!"

"Well then, you're in luck," Sera replied with a Cheshire grin. "You won't be spending three days in some scorching hot desert."

Lava pit, everyone besides Rock thought at the same time.

At that moment, Trent, in his golden retriever form, jumped back onto the cliff and ran over to Sera with the blue gemstone (the one Sera threw away earlier) dangling from his mouth. Sera knelt down, took back the gemstone, and praised Trent for being a "good boy" by scratching his belly. After a long while, everyone was getting impatient with the two of them, especially Rock.

"If you're going to be doing that all day, could you at least send us on our way or something?" Rock asked angrily.

"Why of course. I'll send you on your way as soon as I tell you where you're headed," Sera grinned in response. "I'll be paired with Trent and we'll be doing our training somewhere close to here, so we won't have to teleport. Moto-chan and Berserker-kun will go to the beach for water training. Kera, I'm going to have to ask that you go with Tim to the wasteland. Last, but not least... Rock and-"

Title: WTF High's School Defense Force - Lesson X
Class: 4D
Room: 104
Time to find out what happened after the grand battle on the bridge! Blargh... it was barely even a battle... ("~_~)
*****

The crisp morning sun of the Autumn season shone through the clear glass window and into the bedroom within. The sunlight revealed the titles of the books that were securely placed on the bookshelves that took up one side of the room. A bulletin board filled with pictures of family vacations, school field trips, and summer camp took up the opposite side of the room. Right under the pictures with the top end against the board was a black L-series "Headless" Steinberger bass.

"Mmmph..." Sandra moaned and rustled about from under the sheets as soon as the sunlight hit her eyes. She pulled the sheets over her head to block out the sun and sleep for a while longer, since the alarm didn't even go off. She didn't even need to wait for the alarm for she became alarmed when she realized that something was wrong. Snapping her eyes open, she quickly sat up and pulled back the covers. Her eyes immediately went wide in horror when she realized that she was not only naked and covered with the smell of sweat, urine, and semen, but...

"Mmmph..." Heather moaned in her sleep as soon as the sunlight hit her eyes. Those same eyes snapped open when she realized she was in the wrong bed.

"Huh... why didn't I notice this sooner," Fallout muttered as he examined what was left of his scorched backpack. The bottom of the backpack broke causing all of his books, pencils, erasers, markers, binders, notebooks, crumpled up newsletters, ruler, hole-puncher, post-its, moldy sandwiches, goldfish, loose change, and gum to spill out onto the floor. He gave out a heavy sigh, then went in search of something temporary before asking his parents for a new backpack. After finding nothing in his closet, he went upstairs to the attic to see if there was anything there.

What he found in his attic was a backpack made out of what appeared to be material from an old black and white carpet. In other words, it was a carpet bag shaped just like a backpack that used a hood instead of a zipper and the straps were actually chains. It was mostly black with what appeared to be a Yin-Yang symbol on the hood and around the symbol were the characters for fire, water, earth, wood, and metal in white. Seeing nothing else available, Fallout picked up the bag and left the attic.

Hmm... I wonder if it was a good idea to leave Heather with Sandra, Fallout thought to himself as he made his way back to his room. I'd had left Heather at her place if I didn't hear that message she left her parents. Oh well... I'm sure there's no problem at all. I hope this backpack doesn't have fleas or anything like that.

"Okay... breathe..." Sandra instructed to both herself and her unexpected guest. She took three deep breaths all the while saying, "Breathe in... breathe out... inhale... exhale... now tell me why the fuck you're in my room."

"I don't know! All I remember is going home after cheerleading practice!" Heather cried as she covered up her body with the bed sheets as best she could. "I don't remember anything that happened after that!"

"That's after school, right?" Sandra asked. "I don't remember anything that happened after school, either."

"You don't think... we... did... stuff...?" Heather faltered as she stared into Sandra's eyes in horror. Her trembling hands gripped the bed sheets in aguish and she looked just about ready to cry. "Wh-what... what have... we... are... we..."

"D-don't worry... I... I don't think we d-did anything," Sandra stammered for she was also worried about that possibility. When she realized that the other girl was close to breaking down than she was, she knew what she had to do.

"Y-you... you really... think so?" Heather asked with a glint of hope in her eyes. Unfortunately, her hopeful expression faltered and her eyes went downcast again. "W-we're b-both n-naked and sh-sharing a bed, though."

"If we did, it'll be a secret between the two of us," Sandra replied with a nervous grin. With an obviously fake chuckle, she added, "Unlike a guy, I wouldn't go blabbing about this, saying I scored and shit... or in this case, pissed."

"O-of course," Heather managed to giggle in response. Whether she actually thought the joke was funny or thought it was so lame it was funny, she started cheering up.

"We should get this... stuff... off of us and get to school right away. Go ahead and use the shower first. My parents are almost never home, so we're probably safe in terms of keeping this a secret," Sandra chuckled as she leapt off the bed and started putting on any dirty clothes she could find. "I'll make sure the coast is clear, just in case, then see if I can find something for you to wear."

Heather nodded her head in agreement as she watched Sandra leave the room to make sure the house was still empty. She still felt uneasy about the whole thing, but found herself heading for the bathroom to take a shower anyway. She figured she might as well go along with Sandra's advice, clean herself up, and get ready for school. She also thought about what she should tell her parents once she got home.

Holy crap, my ass hurts, Sandra thought to herself right after she left her room. She wasn't an idiot... she knew something more happened during the time she couldn't remember. The dried semen she was covered in was proof enough.

*****

Monica stood completely naked in the bathroom with a roll of elastic bandages in her right hand. She stared at it for a long while, then sighed, *I didn't wanna wear these fer school, but...

After hesitating a while longer, she unrolled the bandages and started using them to bind her breasts to her body. She was used to binding her breasts when she was training under the Double-Sword Demon-Slayer. It proved to be effective as a form of support and the speed of her movements slightly improved as a result. However, when she started school, she decided to try and be like everyone else since she was expecting a peaceful school year. Now that she knew it wasn't going to be a peaceful school year, she knew she had to be prepared.

With that in mind, she wrapped the bandages tightly around her chest area until her breasts appeared a few sizes smaller than they actually were. Once that was done, her eyes went down to her lower body. After a moment of more hesitation, she went to work on covering up her crotch with the bandages by making tight, yet flexible panties out of them. Once that was done, she got dressed, left the bathroom, and got ready for school in that order.

*****

The continuous spattering of the shower's water rang like a mantra through Heather's mind. She stood under the water for a long while, mulling over her unexpected predicament. She saw the date on the digital alarm clock and realized that she had lost two days worth of memories instead of one. The young cheerleader was so absorbed with her thoughts that she didn't notice the bathroom door opening.

"Oh, you're not done yet?" Sandra asked as she entered the bathroom. She closed the door behind her and dropped a change of clothes on top of the hamper. "Turns out my parents aren't home right now, so we're safe... for now anyway. I got you some clothes that might fit you and breakfast is on the table. Let me know when you're done. I can't go to school smelling like this, after all."

Heather peeked out from behind the shower curtain and noticed that Sandra was keeping her eyes on the clothes. She wondered how the violet-eyed girl could stay calm about all this. Then she remembered that the other girl wasn't acting very calm when they woke up next to each other. When Sandra turned to leave, Heather suggested, "Um... if you... don't mind, it'd be faster if we just showered together... because it's faster... and wastes less water."

Sandra kept quiet for what seemed like an eternity. Heather started mentally beating herself once she realized what she was suggesting. It didn't seem like a big deal to her at first because she always showered with other girls after cheerleading practice. Without a word, Sandra stepped out of the bathroom and closed the door behind her. Once she did, she leaned back against the door with her hands on the doorknob.

S-shower together? A-after what happened? Is she for real? Sandra thought to herself with an anguished expression on her face. She began to walk away, but only took a couple steps before she stopped and looked back. Her sharp violet eyes stared at the bathroom door for a couple of seconds, then she walked back in again. After locking the door, she smiled and said, "I just checked the time and I guess we really do have to shower together if we don't wanna be late."

In apartment room 5011 of a fifty storey building, Tim was preparing eggs, bacon, toast, and sausages for breakfast. The morning sun shone through the sliding glass doors that led out to the concrete balcony. The sound of sizzling grease and of the fan above the stove filled the peaceful air.

"Mmm..." Eria roused from her sleep once the smell of freshly cooked bacon reached her nose. She slowly opened her eyes as the sun flooded them with light. While still lying in bed with the sheets up to her chin, she turned her head towards her master and noticed that he was making breakfast. "Master Tim? Why didn't you wake me? I could've made breakfast if you wanted."

"It's fine. Didn't want to wake you," Tim replied as he placed two sausages, a sunny side up fried egg, and four pieces of bacon on each of three plates he had out. He placed two of them on the coffee table, then walked over to Eria with the third plate in his hand. Reaching out with his free hand, the former assassin pulled back the covers revealing that Rebecca was tied-up and sleeping between Eria's legs.

Eria's wrists were tied together and pressed against the small of her back with each hand pressed close to or against the opposite elbow. All she wore was a white short-sleeved blouse with the buttons undone and nothing underneath, which meant her ringed breasts were exposed to the morning light. Her knees were bent and her ankles were shackled to Rebecca's with chains. Rebecca had to sleep face down with her ankles tied to her thighs and her arms tied behind her back in the same manner as Eria's arms. A ring gag was used to attach the mahogany-haired girl's mouth to the clips that decorated Eria's pussy. As a result, a lot of drool collected there.

The first thing Tim did was remove the clips from Eria's pussy, causing the light brown haired girl to squirm a little in pain. After that, he placed the plate of food that was in his hand under Rebecca's nose. He lightly shook Rebecca awake before removing the ring gag from her mouth so that she could eat. He didn't bother untying either girl and he had no intention to until breakfast was over. He took the two sausages on Rebecca's plate and stuffed them two thirds of the way into Eria's wet pussy and dry ass. Two pieces of bacon were placed on the inner thigh of each leg while the sunny side up egg was placed directly above the clitoris.

"Ah..." Eria moaned in pleasure as she felt the girl between her legs go after the pieces of bacon on her inner thighs. Her vaginal and anal walls gripped the warm sausages as her own juices mixed in with the grease. Her first orgasm that morning sent her into override mode when the yolk from the egg spilt onto her exposed clit. As that went on, Tim fetched another plate and started feeding the frenzied slave girl with a fork.

Eria probably had at least three orgasms before Rebecca was finally finished with her breakfast. Understandably, Eria still had quite a bit to go before she was finished hers. Setting Eria's plate down, Tim untied Rebecca's arms and legs before ordering her to clean up her mess. As Rebecca obediently licked up the grease and girl juice from Eria's pussy, Tim continued feeding Eria the rest of her breakfast.

Once Eria was done eating her breakfast, Tim released the two slave girls' ankles and undid Eria's arm bindings. Once both of them were released, he said, "Go shower together."

"Yes, Master," Eria and Rebecca bowed their heads at the same time, then went into the bathroom to shower together. Once Tim heard the water running, he went over to his own plate and ate his breakfast. His sharp ears picked up the sounds of giggling coming from behind the bathroom door, but decided to ignore it and let them have their fun.

Meanwhile, Sandra and Heather were back-to-back under the constant stream of the warm shower they were awkwardly trying to enjoy. Both of them snuck curious glances at each other's body when they thought the other wasn't looking. However, they caught each other looking at the other's body at the same time and immediately looked away with embarrassed looks on their faces. When their backs accidentally touched, the two girls froze up at the same time.

"Um... I'm done, so..." Heather began as she turned her head to face Sandra's. When the other girl didn't respond, she added, "I need to get out."

"Huh?" Sandra snapped back to attention when she realized that she was the one standing in front of the curtains. She immediately turned around to move out of the way. "S-sure! I'll just..."

Heather maneuvered her way around Sandra to get to the curtains and leave the shower. As both girls tried to get out of each other's way, their nipples brushed lightly against each other causing a chill of pleasure up their spines and against their ashamed faces. As a result, Heather rushed out of there as fast as she could while Sandra accidentally drove her right thigh into the other girl's crotch. The chestnut haired girl quickly stumbled out of the shower and left the bathroom in a hurry.

"Um..." Sandra sweat dropped when she noticed that the change of clothes she prepared for Heather was still on top of the hamper. That meant that Heather was out in the hallway right now, naked and dripping wet. The violet eyed girl visibly relaxed when the chestnut haired girl came back inside the bathroom.

"This is Super Monkey Fist Radio on 99.95 FM! Looks like we've got sunny skies today in-"

"Ugh..." Rock roused awake to the morning radio weather forecast being played on his clock radio. He grabbed the radio without even getting up and threw it out the window. A couple minutes after the sound of a screeching cat due to the flying radio, the youngster finally got up and got ready for school.

He looked around his room before throwing on a pair of sneakers and a jacket. After that, he was out the door and on his way to school.

Of course, as soon as he realized that he wasn't wearing any pants, he mugged the guy who was laughing at him and stole his jeans. Turns out those jeans were stolen from some other guy in the first place.

*****

"Hector! Wake up!" Sandra knocked on the door to her younger brother's room before making her way over to her younger sister's. "Dice! Wake up!"

"I thought you said no one was home," Heather said with wide open eyes.

"I said that my parents weren't home," Sandra explained. "I wasn't worried about those two. A bomb could go off and they wouldn't even notice. Jesus, they're still sleeping. Wake up or I'm gonna slash you with cold water!"

When neither Hector or Dice responded, Sandra sighed and headed off towards the bathroom to fetch a bucket of cold water. Unsure what to do, Heather decided to follow along and see what happened next.

*****

"I'm awake!" Trent shouted as he suddenly sat up in his desk. He blinked, then looked around the classroom to see that it was empty. His eyes turned towards the window and he noticed that the sun was rising. It was then he realized that he had been sleeping at his desk for the past eighteen or so hours. Scratching his head, he got up from his desk and headed for the washroom.

"Ack... my head hurts from all this jumping around," Fallout groaned as he made his way to school. "Attention! Do not read any further if you are either too young, not allowed to view this kind of content in your region/area/whatever, offended by this kind of material, or related to the author by blood! In other words: Read at your own risk!"

"Little late there," Monica remarked.

"I know..." Fallout groaned again.
