A girl/ guy has super powers to change genders. They ended up joining the army but to stay one gender is hard and draining. So joint the imperial army they must be a man. Now he had kept it a secret for months: and even going the favor of a general and another fellow Conrad. That Conrad found him alone in the lake bathing and decided to join him. Our Guy can’t stay a man for long and went to the lake to get privacy immediately, realizing that his Conrad had found him, he has turned back into he and saw the Conrad, of course flirted with him, and he flirted back to not make it weird. His Conrad then explained that his power turns him into like a water monster but his breath control under water is amazing and decides to give the guy head now when an extreme pleasure the genitals kinda turned to the other genitalia .

Chapter 1: The Lake’s Forbidden Transformation

The water was cold, a shock that stole the breath from Alex’s lungs before settling into a tolerable, then pleasant, chill. It was a relief to be free of the uniform, the binds, the constant, vigilant press of fabric against a body that felt perpetually two sizes too small in the wrong places. Here, in the secluded gloom of the forest lake at dusk, Alex could be simply a body in water. The mirrored surface, stained orange and purple by the dying light, broke and reformed around their movements.

They swam a few strong strokes, then floated on their back, staring up at the first pale stars piercing the deep blue. The air smelled of wet pine and decaying leaves, a clean, honest scent. For a few stolen minutes, the gnawing tension in their chest unclenched. The strain of maintaining the form—the broad shoulders, the flat plane of the chest, the subtle, daily reinforcement of a face that was handsome but not quite their own—eased. In the water, everything felt softer, less defined.

A twig snapped on the bank.

Alex dropped their feet, treading water, heart jackhammering against ribs. “Who’s there?”

“Relax, Volkov. It’s just me.” Conrad Demir’s familiar, easy-going voice drifted from the shadows of a gnarled oak. He stepped into the faint light, grinning, his hands raised in mock surrender. “Saw you slip away from camp. Thought you might be deserting.”

“Scouting,” Alex said automatically, the soldier’s mask slamming back into place. They kept their shoulders submerged. “Water access point. It’s clear.”

“Right, scouting.” Conrad kicked off his boots, then sat to peel off his socks. “Looks very thorough. You checking for leaks in the lakebed?”

“What are you doing, Demir?”

“It’s a hot spring night and I smell like a saddlebag. I’m joining your scouting mission.” He stood, pulling his shirt over his head. The last of the light caught the defined lines of his torso, the old, silvery scar that cut across his ribs. He was already unbuckling his trousers.

“Wait—” Alex started, but it was too late. Conrad waded in, hissing at the cold, his dark hair plastering to his forehead as he submerged to his shoulders. He swam over with powerful, lazy strokes. “See? Better. No krakens in here. Just us minnows.”

Alex maintained a careful distance. Conrad was always like this—friendly, tactile, clapping shoulders, sharing a canteen. It was harmless. It was torture.

“You’re invading my quiet,” Alex said, but there was no heat in it.

“Your quiet was looking lonely.” Conrad floated nearby, his eyes closed. “Nice spot. Reminds me of home. We had a lake like this, deep and dark. My brothers and I would dare each other to touch the bottom.”

“Did you ever make it?”

Conrad opened one eye, a sly smile playing on his lips. “I’ve got tricks for that. Better than tricks—I’ve got gills when I need them.” He tapped his neck. “Comes in handy.”

“Show-off.”

“Always.” Conrad rolled in the water, facing Alex. His gaze was direct, warmer than the evening air. “You’re always so tense, Volkov. Even now. What’s got you wound so tight?”

The question, so casually asked, hooked something deep inside Alex’s gut. You. This. Everything. “Just thinking about the push into the northern pass. Heard the fortifications are brutal.”

“Right now, I’m not thinking about the northern pass.” Conrad drifted closer, the water rippling between them. “I’m thinking this is the first time I’ve seen you without that perpetually worried crease between your eyebrows. It’s a good look. You should try it more often.”

The compliment, flirty and soft, landed like a physical touch. Alex felt a treacherous warmth spread through their chest, a loosening. They were so starved for something real. “You’re full of it, Demir.”

“Am I?” He was close enough now that Alex could see the droplets clinging to his eyelashes. “I don’t think I am.” His foot brushed against Alex’s leg under the water—an accident that wasn’t.

The contact was electric. A jolt went through Alex, a surge of wanting so acute it was painful. The careful control, the dam holding back the true self, trembled.

Conrad saw the shift. His playful expression softened into something more intense, more curious. His gaze dropped to Alex’s mouth. “You ever just… stop thinking, Alex?”

Alex barely had time to gasp a reply before Conrad closed the final distance. His lips were on theirs, tentative at first, then sure. The kiss was warm, tasting of lake water and something uniquely Conrad—wild and free. It was everything Alex had forbidden themselves to imagine.

It was everything Alex had forbidden themselves to imagine. Conrad’s mouth was soft but insistent, his hands coming up to cradle Alex’s jaw, thumbs stroking the stubbled line of it. The world shrank to the cool silk of the water, the heat of the body pressing close, the overwhelming rightness of the touch. Pleasure, sharp and sweet, blurred every carefully constructed boundary.

And with it came the terrifying, familiar ripple beneath the skin.

Alex flinched back, breaking the kiss with a gasp that was half pleasure, half panic. Their body thrummed with a dangerous current, bones whispering of change, muscles softening in protest against their will.

“Whoa,” Conrad murmured, his breath warm against Alex’s cheek. He didn’t let go. “It’s okay. It’s just me.”

“Conrad, you don’t understand—”

“I understand that I’ve wanted to do that since the first time you outmaneuvered me in sparring drills.” His smile was a lazy, beautiful thing in the twilight. He leaned his forehead against Alex’s. “I understand that I don’t give a damn about any of the other noise. Just this.”

“I’m not…” The words died. I’m not what you think I am. The confession stuck, a jagged rock in their throat. To say it was to lose everything—this rank, this respect, this fragile belonging. This man.

“You’re not what?” Conrad prompted, his voice low.

Alex’s mind raced, a trapped animal seeking any exit. The truth was a locked door. But maybe… maybe they could have just this one thing. In the dark. In the water. If they held on tight enough, maybe the form would hold, too.

“I’m not… experienced with this,” Alex said, the half-lie tasting like ash.

A slow, understanding smile spread across Conrad’s face. “That’s alright. Neither am I. Not with… guys.” He said it quietly, like a secret just for them. “Figured it out looking at you, I guess.”

The admission was a punch to Alex’s chest. He was gay. He saw Alex as a man. He wanted the man. The fiction.

The ache of it was exquisite and horrifying. To be wanted so completely for the very thing that was a cage.

Conrad kissed him again, deeper this time, and Alex surrendered to the sensation. They let Conrad’s hands explore the broad shoulders they’d crafted, the flat planes of the chest that were both armor and lie. Each touch was a brand, a reinforcement. Stay. Hold. Do not break.

When Conrad’s mouth trailed from his lips, down the column of his throat, Alex’s head fell back. The sky was a deep violet now, the stars brighter. They focused on them, on the pinpricks of cold, distant light, as Conrad kissed a path down his torso. Every nerve was alight, screaming with a pleasure so intense it was a kind of violence. The shifting pressure inside them built to a crescendo, a tidal wave threatening to crash and reshape the shore.

His lips reached the trail of dark hair below Alex’s navel, and his hand slid lower, beneath the water.

Alex knew he could not let go of his form.

So he allowed Conrad to kiss down his torso down to his cock. His form stayed put. Through it was a struggle—a monumental, screaming internal struggle against a nature that begged to be fluid, to match the honesty of the pleasure with an honest shape. They locked every muscle, every instinct, into the rigid configuration of Alex. The soldier. The man.

It worked. The body held its deception, even as Conrad took him into his mouth.

The world dissolved into white-hot sensation. Alex’s hands found Conrad’s hair, not pushing or guiding, just anchoring themselves to the reality of him as the feeling ripped through them, ruthless and perfect. A choked sound, part sob, part gasp, tore from their throat. It was too much. It was a revelation performed on a forgery.

After, Conrad resurfaced, wiping his mouth with the back of his hand, a look of dazed triumph on his face. He wrapped Alex in his arms, holding them close in the cool, dark water. Alex trembled, the aftershocks physical and emotional.

“See?” Conrad whispered into his hair. “Just us.”

But as the heat faded, a cold clarity seeped in. Conrad held a man in his arms. Alex clung to the lie, their true form a screaming ghost beneath the skin, more suppressed and alone than ever. They had gotten what they craved, and it felt like an annihilation.

They had gotten what they craved, and it felt like an annihilation. Conrad’s arms were a warm, solid band around him, keeping him afloat, keeping the lie intact. Alex pressed his face into the damp skin of Conrad’s neck, breathing in his scent—lake water, sweat, something wild and green that was just him. The pounding in his chest was starting to slow from a frantic drumbeat to a heavy, aching throb.

“You’re shaking,” Conrad murmured, his lips moving against Alex’s temple.

“Cold,” Alex lied, the word muffled.

“Bullshit. The water’s fine.” Conrad pulled back just enough to look at him. His eyes, even in the near-dark, were searching. “That was… fuck, Alex. That was something else.”

Alex couldn’t meet his gaze. He looked over Conrad’s shoulder at the black line of trees. “Yeah.”

“Hey.” Conrad’s hand came up, cupping his cheek, forcing his face back. His thumb stroked the high bone. “Talk to me. Was that not okay?”

“It was okay.” It was the most devastating thing that had ever happened to him. “More than okay.”

“Then why do you look like you’re about to be sick?”

Because I am a lie. Because you want a man, and I am a costume. The words burned on his tongue. Instead, he did the only thing he could think to do—he kissed Conrad again. It was a desperate, hungry thing, all teeth and clinging hands, an attempt to swallow the truth and replace it with sensation.

Conrad responded with a low groan, his surprise melting into instant, eager heat. He walked them backward until Alex’s shoulders met the slick, mossy bank. The earth was cool and solid through the water. Conrad’s body was a furnace against his front, pinning him in the best way.

“Want you,” Conrad breathed into his mouth, the words ragged. His hands were everywhere, sliding over slick skin, mapping the territory he’d just claimed with his mouth. One hand drifted lower, kneading the muscle of Alex’s ass, pulling their hips tighter together. The hard length of Conrad’s cock pressed against Alex’s thigh, a blunt, demanding heat.

Every nerve in Alex’s body was a live wire. The pleasure was a riptide, pulling him under, eroding the walls he’d built so carefully. Holding the form was a physical strain now, a grating, bone-deep effort that made his muscles quiver. He could feel the subtle, unwanted softening at the edges, a betrayal of biology. He clenched his jaw, focusing on the weight of Conrad against him, the rough texture of his hands, the taste of his kiss—anchors to the male form.

“I want you, too,” Alex gasped, and it was the truest thing he’d said all night.

“Tell me how,” Conrad urged, his voice dark with want. He rocked his hips, a slow, grinding promise that made Alex see stars. “How do you want it?”

The question unraveled him. All his careful control, the disciplined containment, shattered under the raw need in Conrad’s voice. “Just you. However. Fuck, Conrad, now—”

It was all the invitation Conrad needed. He spun Alex around gently, pressing his chest against the cool bank. Alex braced his forearms on the soft earth, his head bowed. The night air was cold on his wet back, a stark contrast to the heat pooling low in his belly. He heard Conrad spit into his palm, a crude, wet sound that sent a jolt of pure anticipation through him.

Then Conrad’s hand was on him, slick and rough, stroking his own cock before pressing the blunt head against Alex’s entrance.

“Relax for me,” Conrad whispered, his other hand splayed on Alex’s hip, holding him steady.

Alex tried. He forced a breath out, but his whole body was a taut bowstring. This was the point of no return. This would break him. The pressure built, insistent, overwhelming.

Conrad leaned over him, his chest flush against Alex’s back, his mouth at Alex’s ear. “I’ve got you. Just let go.”

And Alex did. He let go of the last shred of will holding his form rigid. As Conrad pushed inside, a broken, ragged cry was torn from Alex’s throat. It was a noise of pain, of pleasure, of profound relief. The stretch was exquisite, a burning fullness that devoured every thought.

He fucked him with a steady, deep rhythm, each thrust pushing Alex harder into the bank, each withdrawal a sweet agony. The world blurred into sensation: the slap of skin on skin, the ragged harmony of their breathing, the primal smell of sex and earth. Alex pushed back against him, meeting every drive, his fingers clawing into the mud.

Alex struggled to hold onto the form to keep Conrad. He clenched every mental muscle, fighting the sweet, seductive release of shifting, the body’s desire to flow and adapt even to this. But as he grabbed Conrad’s head, pulling him down over his back, his hands ran along the sides of Conrad’s neck.

His fingers found not smooth skin, but a series of slender, firm slits, flush against the muscle. Gills. They trembled under his touch, a subtle flutter of a hidden, monstrous biology. Conrad froze for a fraction of a second above him, his rhythm stuttering.

In that instant, their eyes met over a shoulder. Two secrets, laid bare in the dark. Not a man. Not just a man. Something else.

The gills fluttered under Alex’s fingertips, a faint, rhythmic pulse like a second heartbeat. Conrad went utterly still inside him, his breath hitching. The intimate connection didn’t break, but the mood shattered and reformed into something sharper, more dangerous.

Alex knew about the water adaptation. The whole squad did. Conrad could hold his breath for twenty minutes, swim like an eel. It was a tactical advantage, a neat party trick. But this… these visceral, living slits beneath his fingers… this was the anatomy of a monster. This was the extent of it.

“You—” Conrad’s voice was a strangled thing in the dark.

Before he could pull away, Alex tightened his grip on Conrad’s neck, not in rejection, but in anchor. He pushed back against him, taking him deeper, a raw, physical affirmation. “Don’t you fucking stop,” Alex growled, the command gritty and desperate.

A shudder wracked Conrad’s frame. The confusion in his muscles melted, superseded by a surge of something like gratitude, a desperate hunger. He drove into Alex again, his rhythm turning rougher, less controlled. His mouth found the junction of Alex’s shoulder and neck, and he bit down, not hard enough to break skin, but enough to claim, to punctuate the frantic snap of his hips.

“You feel that?” Conrad gasped against his skin, his voice thick. “You feel what I am?”

“I feel you,” Alex panted, the words punched out with each thrust. “That’s all.” It was a lie. He felt the impossible contradiction of it—the human heat sheathed inside him, the alien biology beneath his hands. He was fucking a man who wasn’t entirely a man, while pretending to be a man he wasn’t. The irony was a live wire in his gut.

Conrad’s hand slid around from Alex’s hip, calloused fingers wrapping around his cock, stroking him in time with his thrusts. The dual sensation was overwhelming. Alex’s vision whited at the edges. The pleasure was a riptide, pulling him under, threatening to dissolve the last of his control. He could feel the ache in his bones, the whisper in his blood, the urge to let go, to soften, to become Alexandra in this moment of brutal, accepting passion.

He fought it. He focused on the pain-pleasure of Conrad filling him, on the rough grip on his cock, on the wet, filthy sounds of their bodies meeting. He locked every muscle, every neuron, onto the form of Alex. He was a soldier. He was a man. He was this.

“Conrad—I’m gonna—” The warning was a ragged strip of sound.

“Come for me,” Conrad ordered, his voice guttural, his pace becoming punishing. “Come on my cock, Alex. Show me.”

The use of his name, the sheer proprietary command, shattered him. Alex’s body arched, his back bowing as a climax tore through him with violent intensity. He came over Conrad’s fist with a choked-off cry, his release streaking the dark water. The convulsions of his orgasm clamped down around Conrad, pulling a deep, ragged groan from the man above him.

Conrad’s thrusts lost all rhythm, becoming short, frantic jerks. He buried his face in Alex’s back, his teeth gritted, a low, continuous sound vibrating through his chest as he emptied himself inside Alex. They stayed like that, locked together, trembling as the aftershocks subsided.

The only sounds were their harsh breathing and the lap of water against the bank. Slowly, Conrad softened and slipped out. He didn’t let go. He turned Alex in his arms, pulling him close, chest to chest. The water felt suddenly freezing.

Conrad searched his face, his eyes wide, vulnerable. The playful soldier was gone. In his place was someone laid bare, monstrous secret physically touched and not rejected. “You felt them,” he whispered.

“Yeah.” Alex’s voice was hoarse.

“You’re not… you didn’t…”

“I told you not to stop.” Alex looked away, toward their discarded uniforms. The moment was too huge, too fragile. He’d just shouldered the weight of another person’s hidden truth while his own screamed inside his skull.

Conrad’s hand came up, turning Alex’s face back to him. His thumb traced Alex’s lower lip. “Nobody… nobody ever gets that close.”

A pang of guilt, sharp and acidic, cut through Alex’s post-coital haze. You have no idea how close I’m not letting you get.

“It’s just biology, Conrad,” Alex said, forcing a casualness he didn’t feel. “A tool. Like a strong arm or fast legs.” He was describing Conrad’s secret, and justifying his own, in the same breath.

Conrad stared at him for a long moment, then let out a shaky laugh that was mostly air. He rested his forehead against Alex’s. “You’re a strange one, Volkov.” He kissed him, softly this time, a slow seal on something that had fundamentally changed. “A good strange.”

They waded out in silence, the cold air raising goosebumps on their skin. They dressed without looking at each other, the usual soldierly efficiency laced with a new, heavy awareness. As Alex buckled his belt, securing the uniform that was his own cage, he felt Conrad’s eyes on him.

“We should get back,” Alex said, his voice returning to its usual, measured tone. The Alex-tone.

“Right.” Conrad pulled his shirt on. He hesitated, then said, “This doesn’t… change anything. With the squad. With…”

“Nothing changes,” Alex confirmed, cutting him off. It was the only safe answer. For both of them.

They started the walk back through the dark trees, the camp’s distant fires flickering between the trunks. The space between them crackled with unspoken words. Conrad’s secret was now a known quantity between them, a third presence on the path.

Alex’s own secret felt heavier than ever, a stone lodged behind his ribs. He had just experienced the most profound intimacy of his life, and it was built on a foundation of lies. Conrad had shown him a monster, and flinched, expecting fear. All Alex could think was, you have no idea what I’m hiding.

As the noise of the camp grew louder—the clang of mess tins, the low rumble of tired voices—Conrad reached out. His fingers brushed against Alex’s, a fleeting, hidden touch in the shadow of a broad pine.

“Alex,” he said, his voice low. “Back there… you really meant it? That it’s just… biology?”

Alex stopped walking. He looked at Conrad, really looked at him. The proud soldier, the playful friend, the vulnerable, monstrous man waiting for a verdict. He saw the hope there, fragile and fierce.

He saw his chance to bridge one inch of the vast canyon between them.

“Your biology saved your squad in the river crossing at Kal’s Run,” Alex said, his tone even, factual. “It’s a part of you. A strong part.” He paused, letting the words hang. “How could I be afraid of something that keeps you alive?”

Conrad’s breath caught. In the dim light, his eyes glistened. He opened his mouth to speak, but no sound came out. He just nodded, once, a hard, grateful motion.

Alex knew about Conrad’s powers. It wasn’t a secret. Only Alex’s powers were a secret. He just didn’t know the extent of his powers. And now, he did. And he hadn’t run.

They walked the last hundred yards to the camp’s perimeter in a silence that was no longer tense, but charged with a new and terrible understanding. One secret was out in the open between them. The other remained, a ticking bomb in Alex’s chest, threatening to blow their fragile new world apart.
