Chapter Text
"Um... why are we coming down here, Buchou?" Issei asked, looking at her curiously as the duo descended a set of stairs towards the basement of the Occult Research Clubhouse, "Are you letting out Gasper-chan again?"
"Close, Ise-kun," Rias giggled, not explaining more as they reached the bottom, and then pushed open the door, which Issei noticed already had the seals broken despite it not being night yet.
The sight that greeted him when the door opened made him stiffen slightly. Koneko stood there, her arms crossed under her petite breasts, and looking as emotionless as ever. A few feet away, Gasper was fidgeting nervously, dressed in the female version of the Kuoh Academy Uniform, despite the fact that he was a man, and he was wringing his hands together nervously as he glanced at the door.
"Gasper-chan... Koneko-chan? What's going on?" Issei asked, a confused look on his face as he looked at the two of them.
"I brought Gasper out early today," Rias explained, a smirk on her face as she looked at the dhampir boy, "Since we've found a way to help him get over his... social anxiety, I thought we would test it out on you."
"Test it out on me?" Issei repeated blankly.
"You see, Ise-kun," Rias explained, walking forward and patting Gasper on the head, causing him to flinch and blush, "We need to see how far your newfound desire runs. We know it works when it's me, but we don't know if it extends to the other girls in my peerage. If it does, it could be a whole new avenue of power for you."
Issei's blood ran cold. His eyes darted from Rias's triumphant smirk to Koneko's impassive face, and then to Gasper, who looked like a cornered rabbit. "Wait, you don't mean..."
Rias just nodded at his shocked look. "That's right. To help Gasper get over his fear of social interaction, especially with women, I've tasked Koneko with... relieving some of his pent-up stress. It should help him build confidence. And you, my dear pawn, will be watching."
"But... Koneko-chan is a girl! And Gasper-chan is... Gasper-chan is..." Issei stammered, unable to even finish the sentence. The image was already forming in his head, which was similar to the scene with Kiba, and a perverse heat was already blooming in his gut.
"He's a boy, Ise-kun. A very pretty boy who crossdresses, but a boy nonetheless," Rias said dismissively, waving a hand. "This isn't about romance. This is about training. And discipline. Now, pay attention."
Before Issei could process the sheer madness of it all, Koneko moved.
She didn't speak. She didn't hesitate. She simply stepped forward, her movements economical and deliberate, like a predator closing in on its prey. She stopped directly in front of Gasper, who flinched so hard he almost fell over. His wide eyes darted around the room, pleadingly, before landing on the floor.
"K-Koneko-san! W-what are you... P-please..." Gasper stammered, his hands coming up to cover his chest as if to shield himself.
Koneko's response was to grab the knot of the ribbon on Gasper's uniform. She didn't bother untying it. With a sharp, decisive tug, she ripped the silk ribbon from the fabric. The sound echoed in the silent basement.
"Stay still, Gasper," she said, her voice a low, flat monotone. It wasn't a request. It was a command. Her grey eyes were fixed on her task, devoid of any emotion.
"B-but... I... I don't..." he whimpered, his whole body trembling. He looked past Koneko, his gaze desperate as it found Issei. "Ise-senpai... Buchou... a-are we sure I need to do this?"
No one answered him.
Koneko's small, deft fingers went to the top button of Gasper's blouse. Her movements were quick and efficient. Pop. Pop. Pop. The fabric parted, revealing the pale, smooth skin of his chest, the faint, almost unnoticeable swell of pectoral muscle. He was slender, almost delicate, the complete opposite of Issei's muscular frame.
"H-hey... my clothes..." he protested weakly, his hands hovering uselessly at his sides, too afraid to actually stop her.
"You won't be needing them," Koneko stated, pulling the blouse from his shoulders and letting it fall to the floor in a heap. She paused for a fraction of a second, her gaze sweeping over his exposed torso. Then, without a word, she dropped to her knees in front of him.
Gasper let out a high-pitched squeak, stumbling back a step, his hands flying to his mouth. "K-Koneko-san! Wh-what are you doing down there?!"
He glanced over at Issei, who was watching the entire exchange with a morbid, sickening fascination. He could feel a familiar heat stirring in his loins, a traitorous response to the forbidden scene unfolding before him. Rias, standing beside him, noticed. A slow, predatory smile touched her lips.
"I told you," she murmured, her voice a low purr beside Issei's ear, "this is training. For both of them. And for you."
On the floor, Koneko ignored Gasper's panicked stuttering. Her fingers went to the clasp of his skirt. With a flick of her wrist, she unfastened it. The black fabric pooled around his ankles, leaving him in only a pair of frilly, pink panties that did little to hide the distinct and rapidly growing bulge beneath.
"My... my..." Gasper whimpered, his face a brilliant shade of crimson. He squeezed his eyes shut, unable to watch, unable to look away.
Koneko hooked her thumbs into the waistband of the panties. She paused, her head tilting slightly as she looked up at the trembling boy. For the first time, a flicker of something, possibly surprise or curiosity, crossed her otherwise impassive face. She leaned in slightly, her gaze fixed on the sizable lump straining against the delicate fabric.
Then, with a single, decisive tug, she pulled them down.
It sprang free.
And Issei's world stopped.
The organ that flopped out from beneath the frilly pink lace was not what he expected. It wasn't the timid, modest thing he'd imagined belonged to the cross-dressing, cripplingly shy dhampir. This was… monstrous. It was long and thick, even in its semi-hard state, a pale, veiny column of flesh that seemed utterly incongruous with Gasper's slender frame. It hung heavy between his legs, the tip already beading with a clear, viscous fluid.
Issei's jaw went slack. A cold knot of inadequacy formed in the pit of his stomach. He glanced down at his own crotch, a wave of jealousy washing over him so powerful it made him dizzy. That was bigger than his. Bigger than Motohama's, even. It was a genetic lottery he'd lost, spectacularly.
Even Rias let out a soft, surprised "Oh," beside him. Her eyes were wide, fixed on Gasper's endowment with a newfound appreciation.
On the floor, Koneko's composure finally cracked. Her grey eyes widened for a split second before returning to their usual stoicism. She blinked once, slowly. She reached out a tentative hand, her small fingers looking delicate and almost fragile against the sheer girth of the thing. She wrapped her hand around the shaft, her fingers not even close to meeting around its circumference.
"S-so... good..." Gasper whimpered, a completely different kind of whimper now. It wasn't fear. It was a helpless, overwhelmed pleasure. His hips jerked forward instinctively, pushing himself deeper into her grip.
A low groan escaped Gasper's lips, a sound of pure bliss. All the tension seemed to drain out of his body in an instant. His shoulders slumped, and his knees went weak. He put a trembling hand on top of Koneko's head, not to push her away, but for support, as if he would collapse without her.
Koneko looked up at him, her expression unreadable. But then she started to move. Her small hand glided up the shaft, her grip firm. She twisted her wrist slightly on the downstroke, her other hand coming up to cup the heavy, swollen balls that hung beneath. Her touch was clinical, almost businesslike, but the effect on Gasper was electric.
"A-ah... K-Koneko-san... y-your hands... they're so soft... so warm..." he babbled, his head lolling back. His shy demeanor was melting away, replaced by a writhing, lustful creature.
The sight was like a jolt of lightning straight to Issei's groin. His own cock, which had been mere moments ago a source of profound insecurity, was now rock hard, straining painfully against the fabric of his pants. He couldn't look away. He watched as Koneko's pale fingers danced over Gasper's impossible length, saw the way Gasper's hips bucked, and heard the needy whimpers escaping his lips.
A sudden pressure on his crotch made him jump. He looked down to see Rias's hand, warm and firm, cupping his erection through his trousers.
"It seems you're enjoying the show," Rias murmured, her voice a husky whisper against his ear. Her breath was hot, sending a shiver down his spine. "Doesn't it excite you, Ise-kun? Watching our sweet, timid Gasper-chan being touched like that?"
Issei could only manage a choked groan in response.
Her deft fingers made quick work of his belt and zipper. The metal teeth rasped open, and with a tug, she yanked his pants and boxers down to his knees. His cock sprang free, hard and eager, but suddenly feeling inadequate in the open air, dwarfed by the memory of what he'd just seen.
"Don't be shy now," Rias cooed, her fingers tracing the length of his shaft. "Take it out. Start stroking it. I want you to match him. Feel what he feels, but from a distance."
Her words were a poison, a deliciously potent toxin that seeped into his mind. He wrapped a trembling hand around his own cock, the familiar feel of it suddenly foreign. He began to stroke, slowly at first, his eyes glued to the scene in the center of the room.
"Good boy," Rias whispered, her lips brushing against his earlobe. "Now watch. Watch as she takes complete control. Watch him fall apart."
As if on cue, Koneko's demeanor shifted. The clinical efficiency vanished, replaced by a cold, dominant authority. She let go of Gasper's cock and rose to her feet in a single, fluid motion. She looked up at him, her grey eyes boring into his.
"Bend over the desk," she commanded, her voice flat, devoid of all emotion.
Gasper blinked, his lust-fogged brain trying to process the order. "H-huh? B-but..."
"Do it," she said again, her tone leaving no room for argument. She gestured with a jerk of her head toward a sturdy wooden table pushed against the far wall of the basement.
Swallowing hard, Gasper shuffled over to the desk, his massive cock swaying with each step. He hesitated for a moment, then bent over, resting his forearms on the wood. His ass, pale and surprisingly full for such a slender boy, was presented to the room.
Issei's hand tightened on his own shaft, his strokes quickening. The sight was obscene, humiliating, and utterly arousing.
Koneko stepped up behind him, her small frame nearly the same size as his petite one. She ran a single finger down the line of Gasper's spine, making him shudder. Her other hand snaked around his waist, reaching down to wrap her fingers around his straining cock once more.
"So weak," she murmured, her voice a low, monotone taunt. "All that size, and you're still just a scared little girl. Trembling at a simple touch."
Gasper whimpered, a sound of shame and pleasure tangled together. He pushed his hips back, trying to increase the friction of her hand on his length.
"Pathetic," Koneko continued, her grip tightening. She began to stroke him in a hard, relentless rhythm, her movements efficient and powerful, like she was milking a cow. Her small hand flew up and down the massive shaft, the slick sounds of her effort filling the room. "All this power, and you can't even control yourself. You're just a toy. A toy for me to play with."
"A-ah! Koneko-san! I... I can't... I'm going to..." Gasper babbled, his knuckles white where he gripped the edge of the desk. His body was twitching as the pleasure consumed him entirely. He was completely at her mercy.
Issei watched, mesmerized. His own hand moved faster on his cock, mimicking the brutal pace of Koneko's strokes. He was lost in it, in the sheer depravity of the scene.
Then, a sudden, warm pressure on his balls made him gasp. He jumped, looking down to see Rias's small, delicate hand cupping him, her fingers gently rolling the sensitive sack. A wave of pure, unadulterated joy washed over him.
She's touching me.
The thought was a supernova in his mind, eclipsing everything else. Rias Gremory, the woman of his dreams, was physically pleasuring him. He would have died happy in that moment.
Her full, soft breasts pressed into his back, a warm, yielding weight that sent another jolt of electricity through him. He could feel the hard nubs of her nipples through her shirt, and he leaned back into her, desperate for the contact.
"You're doing so well, Ise-kun," she murmured, her lips brushing against the shell of his ear. Her voice was a silken poison, a caress that was also a cut. "Look at you. So desperate. Stroking your own needy cock in a cold basement."
Her fingers gave a gentle squeeze, and he let out a choked moan.
"While our little Gasper-chan," she continued, her gaze fixed on the scene before them, "gets to have another's hand on him. A real, proper milking. Don't you see, Ise? This is your place. This is what you're good at. Watching. Wanting. Feeling that little ache of jealousy while someone else gets what you crave."
Every word was a carefully aimed dart, hitting its mark with perfect precision. The shame was a fire, but her touch was a balm, and the combination was intoxicating. His hips bucked, pushing his cock deeper into his own fist.
"He's so big, isn't he?" Rias whispered, her breath hot against his skin. "So much bigger than you. And Koneko-chan's having so much fun playing with her new toy. She's going to drain him dry, right in front of you. And you'll just stand here, with my hand on your pathetic little balls, and watch it all happen."
"A-ah... Buchou... yes..." Issei babbled, the words catching in his throat. He was so close.
On the desk, Gasper was past the point of coherent thought. "Please... please... I can't... I'm going to...!"
"Be quiet, you perv," Koneko's monotone voice cut through the air, cold and sharp as ice. "Just cum."
Her final, taunting words were the last straw.
With a high-pitched, strangled cry that was half-shame, half-ecstasy, Gasper's entire body went rigid. His back arched violently. A massive, thick rope of cum erupted from the tip of his cock, flying through the air to splatter on the concrete floor several feet away. It was followed by another, and another, an almost obscene amount of fluid gushing from him in long, powerful spurts. He collapsed forward onto the desk, a boneless, shuddering mess, as the last few weak pulses of his orgasm dribbled onto the floor.
The sight, combined with the feeling of Rias's fingers giving one final, triumphant squeeze on his balls, sent Issei over the edge.
"Buchou!" he cried out, his own body convulsing.
His cock exploded in his hand. A hot, sticky jet of cum shot out, landing on the floor in front of him. He felt Rias's grip on him, felt her breasts pressing into his back, heard her soft, triumphant chuckle in his ear, and it all just made him cum harder. He spurted again, and again, his mind going white with pleasure, his body wracked by shudders so intense he thought his bones might shake apart.
He sagged against her, completely spent, his chest heaving. For a long moment, the only sounds in the basement were the ragged gasps for breath and the slow, steady drip of cum from Gasper's spent cock.
Rias finally released her hold on him, taking a step back. She looked down at the mess on the floor, then at the two exhausted boys, a look of profound satisfaction on her face.
"See, Ise-kun?" she said, her voice bright and cheerful, as if they'd just finished a particularly productive study session. "Another successful training session!"
Issei could only nod weakly, his mind still hazy, and he glanced over and saw that his Sacred Gear had appeared again. The gem pulsed, a sign that it was becoming stronger and more in tune with his body, and he couldn't complain at the result.
"Now..." Rias hummed, grinning over at him, "Since it seems that your desires extend beyond just me, I'll have to see about giving you more 'shows' to watch!"
Issei felt a shiver go down his spine, and he knew that his future 'training' sessions would be very entertaining.
