Day 7 – Polyjuice Potion/Centaur Sex
The familiar dungeon walls of the Slytherin common room glowed faintly in the low light, casting long shadows across the cold stone floor. Draco sat on the edge of his bed, holding a small vial in his hand. The swirling liquid inside was thick and murky, unmistakably Polyjuice Potion. Draco's gaze was fixed on it, his fingers tightening around the glass as he considered the enormity of what he was about to do.
He had been toying with this idea for weeks now, ever since he and Harry had discovered certain... shared interests. It was a twisted thought at first, one that Draco hadn't been able to shake. When Harry had confessed his curiosity about the strength and power of centaurs, his fascination with their wildness, Draco had felt something stir deep inside him—a desire to give Harry what he wanted, to take things further than either of them had ever dared to imagine.
And now, sitting here with Bane's hair—collected carefully during their last trip to the Forbidden Forest—Draco was about to make that fantasy a reality.
With one last glance at the potion, Draco took a deep breath and downed the vial in one swift gulp. The change was immediate. His body began to shift, bones creaking and muscles stretching as the Polyjuice Potion took effect. Draco gritted his teeth, the sensation somewhere between pain and overwhelming transformation. His legs lengthened, his body expanding, and within moments, Draco wasn't Draco anymore. He had transformed into Bane, the dark and brooding centaur of the Forbidden Forest.
His chest heaved as he stood in front of the mirror, staring at the reflection of his new form. The human torso was muscular, broader than his own, and his lower half—powerful legs, strong haunches, and hooves—completed the centaur's body. Draco raised a hand to touch his face, marveling at the way his features had morphed into Bane's sharp, rugged appearance. His breath came faster, a mixture of excitement and nerves thrumming through his veins.
Harry was waiting for him in the Room of Requirement.
The door to the Room of Requirement creaked open, and Harry stood in the center of the room, his heart racing. He had been pacing for what felt like forever, wondering what Draco had planned for tonight. Their relationship had always been intense, full of surprises, but this time... this time Draco had promised something different, something wild.
Harry heard the unmistakable clop of hooves before he saw him.
His breath caught in his throat as Draco—no, Bane—stepped into the room. The centaur's towering figure filled the doorway, his muscular chest rising and falling with each breath, and his dark eyes locked onto Harry's. For a moment, Harry was frozen, his mind struggling to process the sight in front of him. It was Draco, but not Draco—Bane's body, Draco's essence.
"Draco?" Harry asked, his voice barely above a whisper, his heart pounding in his chest.
The centaur's lips curled into a smirk, and his deep voice, unmistakably Draco's, answered. "You said you wanted something different, Harry. Something more."
Harry's throat went dry as he watched Draco—Bane—step closer, the sound of hooves against the stone floor sending a shiver down his spine. The centaur's presence was overwhelming, his size and power evident with every step, and Harry's body responded immediately, heat pooling low in his belly.
Draco moved toward him with deliberate slowness, his new, massive body casting a shadow over Harry. "You've always wondered, haven't you? About what it would be like."
Harry swallowed hard, his breath coming in shallow gasps as Draco—no, Bane—loomed over him, his massive chest and powerful legs inches away. His mind raced, half-terrified, half-excited by the possibilities. He had fantasized about centaurs before, their strength, their rawness, but seeing Draco like this... it was something else entirely.
Draco's hand—still human in appearance—reached out, brushing the back of Harry's neck, sending a jolt of pleasure through him. "Do you still want this?" Draco asked, his voice low and commanding, but with an edge of tenderness that Harry had come to crave.
Harry's breath hitched, his body trembling with anticipation. "Yes," he whispered, barely able to find his voice.
That was all Draco needed to hear. With a swift, fluid movement, he turned Harry around, pressing him against the nearest wall. The contrast of the cold stone against Harry's heated skin sent a shiver through him, and his heart pounded in his chest as Draco leaned in closer, the centaur's massive frame surrounding him completely.
Harry's mind spun as Draco's hands roamed over his body, the touch more forceful, more deliberate than usual. Draco's new form radiated power, his hands gripping Harry's hips with a strength that made Harry's knees weak. Draco pulled Harry's robes apart, sliding them off his shoulders and letting them fall to the floor in a heap.
"You look good like this," Draco murmured, his voice deep and resonant, as he let his fingers glide over Harry's bare skin, tracing the lines of his back. "Vulnerable."
Harry let out a shaky breath, his body trembling as Draco's touch moved lower, his hands rough and possessive as they gripped Harry's hips again. Draco pressed his massive body against Harry, his hooves shifting slightly on the stone floor, the sound echoing in the silent room.
Draco reached for the small bottle of lube he had brought, slicking his fingers with it before sliding his hand between Harry's legs. His touch was firm, his fingers pressing against Harry's entrance with a slow, deliberate motion. Harry gasped at the contact, his head falling back against Draco's chest as the centaur's fingers worked him open, stretching him with careful precision.
The size difference was undeniable. Draco—now Bane—was larger, more powerful than he had ever been in his human form, and Harry's body tensed as he adjusted to the sensation of Draco's thick fingers inside him. But the tension was quickly replaced by a deep, aching need, the pleasure building as Draco's fingers curled inside him, brushing against that perfect spot.
"Relax," Draco murmured, his voice low and soothing as he continued to stretch Harry, his other hand resting on Harry's back, holding him steady. "You're doing so well."
Harry's breath came in short, sharp gasps as Draco's fingers moved deeper, the slick heat making his head spin. He could feel the strength in Draco's touch, the way his fingers worked him with slow, deliberate precision, and it was driving him mad.
"I need—" Harry gasped, his voice trembling with desperation. "Please, Draco, I need you."
Draco's lips curled into a wicked smile, his fingers sliding out slowly, leaving Harry feeling empty and desperate. "You're sure?" Draco asked, his voice rough with arousal as he positioned himself behind Harry, his massive form towering over him.
"Yes," Harry breathed, his body trembling with anticipation.
Draco didn't waste any more time. He lined himself up with Harry's entrance, his massive cock slick with lube as he pressed forward, the pressure building as he pushed inside. Harry gasped, his body tensing at the stretch, the size of Draco's new form almost overwhelming. The head of Draco's cock breached Harry slowly, carefully, but the thickness alone was enough to make Harry's breath come in sharp, ragged gasps.
Draco paused for a moment, letting Harry adjust, his hooves shifting on the stone floor as his large hands gripped Harry's hips. He could feel the tension in Harry's body, the way his muscles clenched at the intrusion, and it took every ounce of restraint Draco had not to thrust forward all at once.
"You're doing so well," Draco murmured, his voice a deep, rumbling growl in Harry's ear. His breath was hot against Harry's neck, and his fingers tightened around Harry's hips as he slowly pushed deeper, inch by inch.
The pressure built as Draco sank deeper inside, stretching Harry wider than he'd ever been, the sheer size of Draco's new form making Harry's body tremble. His forehead pressed against the cool stone wall in front of him, his hands braced against it for support as he gasped for air.
"Draco—" Harry's voice was strained, his body taut with the effort of taking him. It was almost too much, but the pleasure that coursed through him, mixed with the overwhelming sensation of fullness, made it impossible to stop.
Draco groaned, his own breath ragged as he buried himself deeper inside Harry, his cock stretching him so completely, so perfectly. "You feel incredible," Draco growled, his hands sliding up Harry's back, his touch possessive and rough. "So fucking tight."
Harry could barely respond, his mind spinning as the sensation of Draco filling him overwhelmed his senses. The pressure was almost unbearable, but at the same time, it felt right, as though Draco's new form was meant to take him like this. The heat between them was unbearable, the room heavy with their ragged breaths and the quiet slap of skin against skin.
Draco began to move, pulling back slowly before thrusting forward again, his movements deliberate and measured, giving Harry time to adjust to the stretch. His hips bucked forward with each thrust, the weight of his massive body pressing Harry against the wall, his cock driving deeper with every movement.
Harry's breath came in short, shallow gasps, his body trembling with every thrust. The sensation of Draco filling him, the raw power behind every movement, was overwhelming. His fingers scraped against the stone wall as he tried to hold on, his legs weak and trembling from the intensity of it all.
"Fuck—Draco," Harry gasped, his voice barely above a whisper as Draco thrust into him again, deeper this time, hitting that perfect spot inside him that made his vision blur. The pleasure was sharp, almost too intense, and Harry's body jerked forward with each movement, his mind spinning from the sensation.
Draco's hands gripped Harry's hips tighter, pulling him back against his cock with more force, his movements becoming more urgent, more desperate. The sound of their bodies moving together filled the room—the wet, slick sound of Draco thrusting into Harry, the deep groans that escaped Draco's lips, and the soft, breathy moans that Harry couldn't hold back.
"Do you like this?" Draco growled, his voice rough with arousal as he drove into Harry again, his hips slamming against him with a force that made Harry's knees buckle. "Being taken like this?"
Harry's head fell forward, his body trembling with the effort of holding on. "Yes—fuck—yes," he gasped, his voice strained as Draco's cock filled him again, the sensation sending shockwaves of pleasure through him. "I—fuck, I love it."
Draco's lips curled into a dark, satisfied smirk as he thrust harder, his movements becoming more erratic, more desperate. The power behind each thrust made Harry's body jerk forward, his chest pressed against the cold stone wall as Draco's massive body towered over him, filling him completely.
"Good," Draco muttered, his breath hot against Harry's ear. "Because I'm not done with you yet."
Harry let out a broken moan, his body trembling violently as Draco picked up the pace, thrusting into him harder, faster, his hands gripping Harry's hips so tightly it was sure to leave bruises. The heat between them was unbearable now, the pleasure building with every thrust, and Harry's breath came in ragged, desperate gasps as he felt himself teetering on the edge.
Draco's hand slid around to grip Harry's cock, stroking him in time with his thrusts, his grip rough and unrelenting. The combined sensation of being filled so completely and Draco's hand working him with precision was enough to send Harry spiraling. His legs shook, his body trembling with the effort of holding on as the pleasure built to a fever pitch.
"I'm close—" Harry gasped, his voice breaking as Draco's hand tightened around him, stroking him faster, his thrusts becoming more erratic, more desperate. "Draco, I—"
"Come for me," Draco growled, his voice low and commanding as he thrust into Harry again, deeper this time, his cock hitting that perfect spot inside him that made Harry's entire body tense. "Now."
It was all Harry needed.
With a loud, broken moan, his body convulsed, his orgasm crashing into him with a force that left him breathless. His cock pulsed in Draco's hand as he came, his release spilling over Draco's fingers, coating the stone wall in front of him. The pleasure was blinding, overwhelming, and Harry's entire body trembled as the aftershocks ripped through him.
Draco wasn't far behind. With a few more rough, erratic thrusts, he groaned deeply, his grip on Harry's hips tightening as he came, his body trembling as he spilled inside Harry, filling him completely. The sensation of Draco's cock pulsing inside him, the warmth of his release, sent another shudder through Harry's body.
For a long moment, neither of them moved, both of them panting, their bodies trembling with the aftershocks of their release. Draco's hands were still gripping Harry's hips, his forehead resting against Harry's shoulder as they both tried to catch their breath.
Finally, Draco slowly pulled out, his chest still heaving with breath. Harry collapsed against the wall, his body spent, his legs trembling from the intensity of it all.
Draco stood there for a moment, his large form towering over Harry, his breath still ragged. He reached out, brushing a hand over Harry's back, the touch surprisingly gentle after the raw, primal encounter they'd just had.
"That was..." Harry started, his voice hoarse, but he couldn't find the words.
Draco smirked, leaning down to press a soft kiss to the back of Harry's neck. "Better than you imagined?"
Harry let out a breathless laugh, his body still trembling as he turned to face Draco. "Yeah," he muttered, his eyes still dazed with pleasure. "Much better."
They stood there for a moment, the intensity of what had just happened hanging in the air between them. Draco's massive form slowly began to shift as the Polyjuice Potion wore off, his body shrinking back to his normal size, but the connection between them remained.
Draco leaned in, pressing a soft, lingering kiss to Harry's lips. "Next time," he whispered, his breath warm against Harry's skin, "your being the ponyman."
