The following day, Helha dutifully attended her classes and continued to strive for the highest possible results. Her mothers were proud of her initial results from yesterday's training session, though they did tease her about going against Sidra's initial instructions. "We're proud of you for pushing yourself Helha, but try to listen to your instructors." One of her mothers gently insisted. "But we're proud of you for clearing that session!" Her other mother cheered. It sounded like she was encouraging Helha to continue disregarding instructions to get higher scores, but the cadet intended to follow her orders to the letter from that point forward.

Her next training session was going to be a one-on-one match against another cadet named Neoma. Her opponent was a year higher than her, but their skill levels were about equivalent. Whether this was a means by Sidra to knock her pride down a level or two, or because Sidra had that much faith in her potential was not clear. What was clear was Helha's intention to defeat her opponent.

The two had never met before, but Helha heard of Neoma by reputation: she was fierce and efficient, with some of the highest scores in the academy. She also came from a well-known family, with relatives in high positions in the fields of business, military, and politics. Helha researched Neoma's statistics on her terminal visor, and she had to admit to being impressed. The cadet once again wondered if she was matched against Neoma to prove her skills, or to be broken down and made to realize that her pride was worthless.

Helha met Neoma outside of the simulator room. The older cadet wore the same uniform, a white skin tight suit with intricate lines running across it, with an opening between her legs that put her pussy and ass on clear display. She was slightly taller than Helha, with a more voluptuous figure. She had long scarlet hair tied in twintails, and an eye color to match. She seemed less than pleased to know that her opponent was a rookie, and she made her feelings very clear.

"I don't know why Professor Sidra put me against you. I imagine this will be a very quick sparring session." Neoma sounded haughty and confident, causing Helha's temper to flare up, but she kept her mouth in check. "Let us begin then." The younger cadet turned a heel and the simulator opened with her approach.

The two cadets stepped inside, and the simulation began without either one of them issuing a command. Perhaps Sidra didn't want to give Helha the opportunity to set her own parameters again. Helha and Neoma stood in two large mechs. They exposed their chests and grew their thick cocks, allowing her erogenous zones to be covered by those layers of gel that served to drive them mad with desire, and in turn, power their mechs.

A large hologram floated in the air, the name of their sparring session: Defeat the Enemy Forces. Beneath that were their given names, and the number zero. It was a competition to determine who could defeat the most enemies in the allotted time. Rules prohibited competitors from fighting one another, and points would be deducted for such conduct, even if it was 'unintentional', since pilots should have better spatial awareness. Above the banner was the timer, indicating that they had ten minutes to fight. Of course, both Helha and Neoma intended to defeat every last enemy before the timer ran out.

The scene changed from white panels to a darkened city, filled with smooth, ornate buildings and statues. "The capital of Nereidian, the semi-aquatic species our people fought those solar cycles ago." The Nereidian were at war with the Enepau and sought to expand their territory. Like the Enepau, the Nereidian were an all-female species, and reproduced similarly to how the Enepau did, a few of them gained male reproductive organs.

The Nereidian thought they could triumph fairly easily, thanks to their renown beauty. They were among the most beautiful and sexually alluring species in the known galaxy. Their music was likewise enjoyed on most planets. Gifted with long, flowing red hair, and pale blue skin, they had clawed hands and feet, with fins on their forearms and legs that enabled them to jet around the water. Certainly a species like the Enepau that relied on sexual energy would be easily defeated by the sirens on the universe.

Reality differed, and the Nereidian were literally fucked into submission by the Enepau, who later sued for peace. The treaty signing was notable, in that the Enepau representatives had sex with their counterpart after the signing itself, so people on both Enepau and Nereidian were treated to a sex show. Thus far, no half-blooded children born of these relations were discovered, but it is noted that both species were 'curious to see how the offspring would look and act'. They were definitely compatible in that area, and the Enepau never shot blanks, so the whole thing became a mystery.

The city quickly flooded with water, and large Nereidian mechs swam out to join the cadets in the city center. Like the Enepau mechs, the Nereidian mechs were anatomically accurate and pale blue in color. After their treaty, the Enepau and Nereidian shared technology, including weapons designs such as the Enepau mechs. The two races had engaged in training exercises, so the simulation around them wasn't so unusual, but underwater combat was a higher level than either of them could expect at their current education levels.

An alarm sounded and the clock began to tick, which signaled the Nereidian forces to launch their attack. The hoard of siren water women giggled and hummed as they moved against Helha and Neoma. They brandished electromagnetic spears, controlled by their own unique energy generators, allowing them to release ranged electrical attacks, and even move through the air and water without the user physically holding it. A similar system was employed by Enepau mechs, providing them some protection, but not enough to walk away unscathed.

Enepau mechs could move fairly well underwater, thanks to improvements made with Nereidian technology, but they could still be outpaced by the water women. Both Helha and Neoma had extensively studied the Nereidian combat tactics, and as such, they were prepared.

The two evaded the initial volley of attacks, and Helha mentally commanded the suit to begin power charging. This signaled the gel pads on her breasts and the sheath around her cock to begin stimulating her. She fired twin lasers from the mech's nipples, and as she expected, her enemies easily swam around them. During the war, the Nereidian were far too fast and agile for their larger mechs, and as such, they employed personal powered suits. The aquatic beings were mostly immune to electricity, but the use of sound was known to be particularly effective.

The mouth of Helha's mech opened and released a supersonic wave that crippled a few of the approaching Nereidian, opening them to an attack. The cadet lined up her nipples and released twin lasers that struck two of the advancing enemies. As they floated back, damaged and stunned, the Enepau combatant dashed forward to finish them off.

Dodging bolts of electricity and thrown spears, Helha smashed one stunned foe into the ground with a stomp of her foot, kicked off from that one and delivered a mighty punch to the second. Her score jumped from zero to two. Her joy was short-lived when her onboard computer notified her that Neoma's score had already risen to three.

Helha's momentary lapse in concentration created an opening that the skilled Nereidian people exploited when she, once again, allowed herself to be grabbed from behind. Two Nereidian mechs grabbed her arms and held them stretched at her sides. "Damn…! Not this time, you-!" Her words were cut off when a third approached and stole a kiss, pressing her mech's soft lips against her own. The sensation was transmitted, an intimate gesture shown during a pitched battle.

"Right, you people seduce your opponents. I know your games." Helha declared. The sirens merely giggled and continued their treacherous games. The blonde cadet struggled against the firm hold of her opponents, and ignored their sultry swimming. The score count put Neoma at five downed enemies, to Helha's two.

The siren that stole a kiss from the bound Helha moved aside, and was joined by two other giggling Nereidian mechs. The first Nereidian and one of her companions immediately targeted her chest. Despite Enepau mechs being strong and highly defensive, they were also as pliable as a normal person, allowing the Nereidian to knead and grope her large bust. The third one had sunk down to her knees and wrapped her own titanic chest around Helha's massive girth.

Errors ran across the screens, indicating that the Nereidian were disrupting her weapons systems while they played with her, so no matter how much sex energy she charged, none of it would go anywhere. Helha knew how to counter such attacks on her weapon and restore its full operational capacity, and she could do it easily even in combat situations, but the Nereidian knew how to affect Enepau soldiers with their feminine wiles.

Two of the Nereidian indulged themselves on Helha's chest as they licked and sucked on the pliable metal breasts. The siren kneeling before her, rubbing her large metal shaft with an equally tantalizing pair of machine breasts, began to tease the blonde Enepau cadet with skilled lips and tongue.

"Mmm~ You're enjoying this~" One of the Nereidian observed in her sultry, dulcet voice. The main cannon throbbed in perfect sync with Helha's actual shaft. The enemies acted loving and affectionate as they teased her body. Though her hands and arms were bound in place, the neural interface link was still active, allowing the determined cadet to begin her counter offensive.

Helha tried to focus on rebooting the weapons systems using the interface, but the Nereidian provided the perfect distraction. The three Nereidian in front of her, sucking on and groping her chest, and massaging her cock with the most perfect breasts she had ever felt, divided her attention. A fourth appeared at her side and casually caressed her ass, and inched towards her holes. The cadet trembled in rapt ecstasy as she felt the same sensations the soldiers from the previous war experienced.

"You don't get extra points for fucking the enemy, rookie!" Neoma derided her opponent over the comms. Helha's pulse quickened in anger and pleasure. She winced and let out a short moan as she felt two fingers tease her pussy. "Why don't you forget the battle and just have fun with us~?" The Nereidian at her side propositioned her. They lightly chuckled as the one between her legs stood up and spread her finely detailed petals, and fully intended to mount Helha then and there to secure the cadet's defeat.

The simulation's capabilities were truly exceptional, for all the most dire of reasons then. Helha felt every lick and nipple, as though the Nereidian were right there with her in the cockpit. She couldn't keep her voice in check, which no doubt gave Neoma plenty to ridicule, and Sidra plenty of reasons to dock points from her final score. Though try as she might, she couldn't free herself from their hold.

The other two enemies seemed to begrudge having to move away, as they were clearly enjoying Helha's breasts, but they made way for the third, who wrapped her arms around the blonde woman's neck, and locked her legs around the Enepau soldier's waist. A sly smirk formed on the Nereidian's mech's lips, promising a paradise before defeat.

The Nereidian gently thrusting her fingers into Helha's pussy guided her cock into the Nereidian in the front. Once properly lined up, the Nereidian mech slammed its hips down, taking Helha's full length inside itself in one move. The pilot winced and bit back her voice. "O-of course she would feel good here, too…!" Helha grunted. The opponent's pussy seemed a perfect fit for her. She was lovingly squeezed and caressed. As rough as the Nereidian siren slammed against her in the mildly uncomfortable standing position, she could only feel a sense of pleasure and ecstasy she had never felt before. It was little wonder why many Enepau soldiers volunteered to serve at the Nereidian base.

"D-Damn you…!" Helha tried to resist the simulated Nereidian mech, and the score counter that would most certainly read in Neoma's favor. "Let yourself go, Helha~" The group of Nereidian soldiers sang in unison. Helha felt those two fingers pull out of her mech's pussy, and become replaced by a Nereidian mech cock, one that was equal in size and girth to her own. She felt it tease her lower lips, running up and down to make her body shiver in anticipation. Without warning, the Nereidian soldier bucked her hips forward, and hilted her own main cannon inside Helha, eliciting a loud moan from the distracted soldier.

Helha had used both her cock and pussy before, but not often enough to become used to the overwhelming sensations. The mech's pussy stretched and molded to fit the opponent's impressive girth, causing Helha to whine in exertion. The Nereidian in front of her clamped down on her cock, seemingly determined to drain her of cum despite the fact that none of it would get to her outside of the cockpit.

There was no use in struggling against the gel that perfectly mimicked the Nereidian's actions to her body, as indicated by the hardened gel dildo thrusting in and out of her overly sensitive pussy, and the sheath around her own cock perfectly replicating every inch of the Nereidian's pussy as her opponent slammed her hips back and forth.

Helha tried desperately to focus on the task at hand: freeing herself and destroying the Nereidian simulations. She did not intend to use a training simulation simply to engage in an orgy at the cost of her assignment. The blue-eyed cadet noticed the that sex energy gauge was registering a higher than normal reserve, but thanks to the Nereidian, none of it could be focused into the main and secondary weapons.

Though that energy couldn't activate the laser arrays, it could be focused elsewhere. "Computer, reroute the -mmm~!- e-energy reserves to the vocal array!" Helha commanded. "If these sluts want to make me cums so badly, I've let them hear my voice when I cum." She declared. As luck would have it, she was about to ride out a powerful orgasm, so she let herself go and enjoyed it fully.

Helha's mech parted its lips and let out a loud and powerful supersonic moan that stunned every Nereidian in a mile-wide radius, including the enemies that were fucking her. With them disabled, Helha quickly restored her weapons systems, and chose to ignore the burning sensation in her body, and the fact that she was sensitive to the touch, as well as the puddles of cum that broke free of her gel sheath and pad.

The battle resumed for the lagging Enepau cadet. She pushed the two Nereidian soldiers away, breaking free of their lovers' embrace. "Activate the main cannon!" Helha barked her orders. She leapt into the hair and released a focused laser from her suit's cock, bisecting and destroying the group of Nereidian enemies that crowded around her as she gracefully spun around like a ballerina.

In one fell swoop, Helha downed half a dozen opponents. Checking the score, she saw that Neoma had accumulated twelve opponents, whereas Helha had only defeated six. Time was not on her side, and the amount of available enemies was beginning to dwindle, propelling her to double her efforts. Since her mech was running at twice its normal efficiency, bolstered by the extra sex energy generated when the Nereidian themselves had their way with her, she felt confident in her chances of victory.

"Have you decided to finally join the match?" Neoma derided her over the comms again. "I assumed you were training to become a Nereidian slut on their homeworld and enjoy gangbangs every day, and our prestigious academy was just a means to that obscene end." The older cadet continued her verbal assault. Helha chose to tune her out and engage the enemy. A group of three Nereidian dashed at her, their spears raised and ready to attack. A quick supersonic scream from her disabled the three long enough to be destroyed with Helha's twin lasers.

Helha made an impressive rebound as she slowly caught up to Neoma's commanding lead. Her boost in strength was beginning to wane as the battle raged on, returning her mech's performance to its normal combat parameters. This was fine, she used that time to calm her overheated body and settle her heart from the Nereidian's seduction gambit. Neoma seemed to have run out of snide remarks since she lost her lead, but she had not lost a step in combat.

At the seven minute mark, the battle had ended with the last Nereidian mech destroyed. The score was an even twenty-six, a tie between the two combatants. When the alarm rang and battle was halted, the simulation reset, restoring the city to its pre-battle state and, much to their shared confusion, eliminating the water entirely. However, their down foes had left their weaponry behind for reasons as yet unclear to the two students.

Sidra appeared between them as a floating hologram. "The two of you fought well. Your skills and efficiency in combat are to be commended." The instructor announced. Neoma's temper flared as her refusal to accept the results became clear. "Commended?! She let herself be fucked in the middle of battle!" The cadet barked. "While I fought on, she was getting pleasured by the enemy!"

Helha tried to maintain her cool, but her failure in battle was just narrated by her rival. Sidra seemed unmoved by the statement. "Apparently your grade in history is in error." The teacher spoke. "During the Enepau/Nereidian war, as a method of gaining a strategic advantage, Enepau soldiers pretended to be captured so the Nereidian would seduce and fuck them, all in order to charge an exceptional amount of energy to their personal suits. This was one of the key strategies that saw our people triumph." Sidra recounted their history.

While Helha had read about that particular strategy, she didn't recall it during battle. If anything, the entire counter was little more than a fluke born of her desperation. Her pride and dignity wouldn't allow her to take credit for such a happenstance, and she attempted to speak her mind. "Commander, I-" She began. A sharp look from Sidra immediately closed her lips. "Your strategy was effective, nothing more." The instructor stated in an icy tone of voice.

Sidra cleared her throat and changed the banner to set the stage for their tie-breaker: Helha Vs. Neoma, and the clock below was reset to ten minutes. "A standard duel, ladies. Ten minutes are on the clock, but I suspect that neither one of you will need that long. The duel ends when the computer confirms that a fatal strike is imminent." With her instructions given, the hologram vanished. "Begin when ready." Her voice rang through the room, followed by the alarm that signaled the beginning of their match.

As soon as the alarm blared, Helha and Neoma dashed at one another and threw a mighty punch that connected in mid-air. The sheer force of their collision released a shockwave that cratered the ground beneath them and shattered the windows of nearby buildings.

Neoma's joy was apparent on the comms. "Heh. I knew this would be easy. I'm not going to lose to some harlot who let herself be swept away by a group of Nereidian soldiers." She spat, her voice full of arrogance and venom. "I know that you weren't implementing some strategy, you were just letting yourself become a Nereidian sex toy. You're a disgrace to the academy, and to the Enepau military!" Her words struck Helha, but the younger cadet would not be deterred.

The two exchanged blows, displaying their incredible martial prowess with fast and strong kicks and punches. Helha seemed to only be slightly weaker in that regard, as she could only narrowly evade Neoma's strikes. As it stood, Helha needed to outwit her opponent, and capitalize on her ego and pride, which is precisely what she did.

Helha left a small opening in her stance, and as she expected, Neoma capitalized on it. The fiery-haired cadet threw a punch straight at Helha's stomach, but the blow didn't have the effect it should have. Helha stepped back, avoiding most of the damage, while using Neoma's own strength against her. She pulled her older rival, setting Neoma off balance, and once behind her, she grabbed her opponent.

"Perhaps you'll enjoy being a sex toy, too~" Helha spoke in a husky tone. She lifted Neoma into the air and hooked her arms beneath Neoma's knees, holding her aloft with her legs spread wide open. Her cock was aimed right at Neoma's pussy, and gently prodded her lower lips. Being in such a vulnerable position did nothing to abate the red-eyed soldier's ego. "Heh. Do you think you can fuck me into submission? You're not worthy enough to even try."

Helha slammed Neoma down onto her titanic shaft, and pushed as deep as she could inside her rival. Thanks to the gel sheath, she felt how hot and tight the prideful cadet was. "If you weren't such an egotist, I could really enjoy this." The blonde girl hissed. She tended to bury her more carnal desires in favor of focusing on her tasks in the academy, but there and then, she wanted to break into Neoma's cockpit and take her directly.

Neoma tried to stifle her voice, but small moans still escaped and reached Helha's ears. Each powerful thrust made the prideful Enepau shudder. "T-This position is demeaning~!" She complained. "Oh? Is it? Which part? Is it the way your legs are spread apart for anyone to look at you? Is it the way your cock and tits are bouncing around every time I thrust into you?" Helha teased her, and noted how tightly Neoma squeezed her, as though she had a bit of a kink waiting to be unlocked.

"Y-You will pay dearly for trying to humiliate me!" Neoma declared. Spotting one of the Nereidian staves, she managed to sync her energy with it and commanded it remotely as a Nereidian would. The staff flew through the air and struck Helha from behind, thrusting a bulbous end into her mech's pussy. The blonde student let out a surprised moan, and temporarily lost her grip on her opponent, a mistake that could cost her victory.

Neoma grabbed Helha's arms and used some leverage to spin herself around, all without letting her opponent's cock out of her pussy. The sheer friction sent pleasant chills down both of their spines. "Let us see which one of us can ready a proper city-leveling blast first, you Nereidian slut." She challenged her foe. Helha grinned and once again hooked her arms beneath Neoma's knees. "You're on."

As Helha thrust her hips harder and faster into Neoma, the scarlet-haired student manipulated the staff just as fast, using a weapon of war as an impromptu sex toy. Neoma divided her energy between controlling the alien weapon and charging her mech's energy reserves, but in her pride, and her begrudging enjoyment of Helha's cock, she kept their current position rather than trying to fight out of it. Though she did make a quick adjustment that would give her more leverage.

Neoma wrapped her arms around Helha's shoulders, and her legs struggled out of the blonde cadet's grip so she could lock her legs around Helha's waist. "Now I've got you, miss rookie." The fiery senior declared in a sultry voice. Helha reached down and grabbed her foe's ass, and gave it a firm squeeze. "Do you now?"

Helha imagined the real Neoma riding her, and watching her large chest bounce with every thrust. She had no love for the egotist, but her mind was flooded by lustful thoughts, so she indulged her fantasies just a bit. Neoma had similar thoughts of course, and felt victory in reach as her orgasm reached a peak. She only came once or twice during the battle, so she was due for a climax at any rate. Unfortunately for her, Helha was even closer, as her systems indicated.

Helha's energy reserves reached their maximum potential, and as much fun as she was having, she gave the command to fire the main cannon. The alarm blared and the simulation ended. Perhaps it was a bit of fun on Sidra's part, but after a flash of light, Helha and Neoma stood in the center of the room, holding onto one another in a similar pose as before, but without Helha's cock buried deep inside Neoma. The girls were frustrated of course, since the simulation ended right before they came, but they fought off their desires to take one another there and then to quench their urges.

Sidra approached the two, prompting Neoma and Helha to separate and stand at attention. "Helha is the victor this time, but you both will receive 100% for this training session. Keep up the fine work." The instructor announced. "You're dismissed." With that, she turned a heel and left the two cadets proud and frustrated.
