Chapter 12: The Compartment Game
The Hogwarts Express cut through the snow-blanketed countryside, a serpent of scarlet steam against the endless white. Inside Elara’s secured compartment, paid for with Galleons from a vault her parents never checked, the world was reduced to a low, rhythmic shudder and the intimate glow of a single lamp. The plush velvet seat absorbed sound, leaving only the whisper of wheels on tracks and their own breathing.
Blythe traced the stem of a crystal goblet with one finger, her third glass of elf-made wine making her eyes soft. “It doesn’t feel real. That we’re here. That we just… left.”
“It’s Christmas break,” Elara said, watching the frost etch patterns on the window. “Everyone leaves.”
“You know what I mean.” Blythe’s gaze slid to the compartment door, locked and warded. “We left with him.”
As if summoned, the door slid open. Severus Snape stepped through, silencing and locking it behind him with a flick of his wand. He wore black travelling robes, still dusted with snow from the platform. He carried the cold in with him, along with a tension that made the warm air seem thin.
“Comfortable?” he asked, his voice a low rumble beneath the train’s hum.
“Luxurious,” Elara replied, not turning from the window. “Your idea of a decoy? The discreet train, while you apparate?”
“The Headmaster believes I am visiting a rare ingredient wholesaler in Vienna. A tedious but necessary fiction.” He shed his outer robes, revealing a tailored black waistcoat and trousers. He looked out of place amid the plush opulence, a sharp knife on a silk cushion. “This,” he said, his eyes finally finding Elara’s reflection in the glass, “is not part of the fiction.”
Blythe shifted, drawing his attention. Since the forest cabin, a change had settled in her. The nervous girl was still there, but beneath it was a new steadiness, a calculating gleam. She had learned the price of things, and was deciding if she wanted to keep paying. “What is it part of, then?” she asked.
“An interlude.” He took the seat opposite them, his long legs stretched out. “A contained event. Like a potion simmering in a cauldron. All elements present, all reactions… contained.”
“Until it boils over,” Elara said, finally turning.
“Then it is ruined,” he finished. He studied them both, a predator assessing how the herd had rearranged itself. “You are both unusually quiet.”
“We’re waiting,” Blythe said, taking a slow sip of wine.
“For what?”
“To see what you do,” Elara answered. She uncurled herself from her seat and moved to stand before him, the train’s sway giving her steps a languid, deliberate grace. “In the cabin, you were in charge. On your territory. This is neutral ground.” She placed one knee on the seat beside his hip, then the other, straddling his lap but not touching him, her skirts pooling around them like a dark cloud. “The momentum is different here.”
Blythe watched, her lips parting slightly. She set her goblet down and rose, her movements mirrored Elara’s. She straddled his other leg, a bookend of youth and intent. They were close enough that their thighs brushed, a line of heat against the fine wool of his trousers.
Snape did not move. His hands remained on the arms of the seat, but Elara saw the pulse jump in his throat. The power here was a trembling, shared thing. “This is a miscalculation,” he stated, but his voice lacked its usual cut.
“Probably,” Elara murmured. She leaned forward, her breasts pressing against the starched linen of his shirt. She didn’t kiss him. She brought her lips to his ear. “But you’re already hard for it, aren’t you?”
Blythe, emboldened by the wine and the shared secret, echoed the movement on his other side. Her tongue flicked out, tracing the shell of his ear. “We can feel it,” she whispered, her hips shifting forward just enough to grind down against the rigid line of his erection trapped beneath his clothes.
A low sound, almost a growl, vibrated in his chest. His hands came up, not to push them away, but to grip their hips, his fingers digging through the layers of fabric. “Little fools.”
Elara caught Blythe’s gaze over his shoulder. A silent agreement passed between them. They moved as one.
Elara’s mouth found his, her kiss brutal and claiming, all tongue and teeth. At the same time, Blythe’s hands went to the fastenings of his trousers, her fingers nimble and urgent. He broke the kiss with a sharp gasp as Blythe freed him, his cock springing out, thick and flushed in the lamplight.
“Fuck,” he hissed, his head falling back against the seat.
Elara took advantage, kissing down his throat, biting at the tendon. Blythe’s hand was already wrapped around his length, stroking firmly, her thumb smearing the bead of moisture at the tip. The train rocked, jostling them together, a relentless, mechanical rhythm that underscored their own.
“You want to watch us, Professor?” Blythe breathed, her voice husky. “Like in the cabin? Or do you want to feel?”
She didn’t wait for an answer. Still stroking him, she turned her face and captured Elara’s mouth in a deep, wine-sweet kiss. It was a performance and a genuine hunger, their tongues sliding together, their moans mingling. They kissed like they were sharing him through the act, their hands on each other’s faces, necks, hair.
Snape watched, his grip on their hips iron-tight, his breath coming in short, sharp pulls. The sight was undeniable: two of his students, lost in each other, using his body as their anchor. The depravity of it was a hot wire in his gut.
Elara pulled from Blythe’s kiss, her lips slick. “Your turn.” She pushed her skirts up to her waist, revealing she wore nothing beneath. She positioned herself over him, the head of his cock nudging against her soaked entrance. She didn’t sink down. She hovered, letting the train’s motion create a maddening, shallow friction.
Blythe, her eyes dark, released him and hitched her own skirts up. She was bare too. She pressed herself against Elara’s side, her hand sliding between Elara’s legs from behind, fingers finding her clit, rubbing in tight circles as Elara continued to tease them both with that shallow, rocking almost-penetration.
“Christ,” Snape choked out. The dual sensation—the hot, wet promise of Elara, the sight of Blythe’s fingers working her—was unraveling him. His control, so absolute in the classroom, was turning to liquid fire in his veins.
“Ask for it,” Elara demanded, her body trembling with the effort of holding back.
His pride warred with a need so profound it felt like annihilation. The train roared into a tunnel, plunging them into momentary darkness broken only by the lamp’s flicker. In the dark, his voice was stripped bare. “Take it.”
Elara sank down, a slow, inexorable descent that made them both cry out. She was tight, impossibly so, and so wet he could feel the heat of her seeping into him. She seated herself fully, her inner muscles fluttering around his girth, and went still, her head dropping to his shoulder.
Blythe’s fingers never stopped. She worked Elara’s clit, her other arm wrapped around Elara’s waist, holding her steady as the train jolted. She leaned in, her mouth on Elara’s neck, sucking a mark into the pale skin.
Snape’s hands moved from their hips, one tangling in Elara’s hair, forcing her head up to claim her mouth in a vicious, consuming kiss. The other hand groped behind her, finding Blythe’s wrist, guiding her fingers to go harder, faster. He began to move his own hips upwards, driving deeper into Elara’s clutching heat.
The compartment was a symphony of filth: the slick, rhythmic sound of flesh on flesh, their ragged pants and moans, the ceaseless, groaning metal of the train. Elara rode him with increasing fervor, each downstroke a gasp, her body arching into Blythe’s relentless touch. The dual stimulation was pushing her swiftly to the edge.
“I’m gonna…” she panted against his mouth.
“Do it,” he growled, biting her lower lip. “Squeeze my cock while you come. Show her how it feels.”
The command sent her over. Her climax ripped through her with a silent, shuddering intensity, her cunt pulsing around him in rapid, milking contractions that dragged a groan from deep in his chest. He fucked her through it, his thrusts becoming jagged, desperate.
Blythe, feeling Elara’s body convulse, let out a broken sound of her own need. She withdrew her soaking fingers from Elara and without a word, turned, presenting herself to Snape, her hands braced against the compartment wall. An open invitation.
Snape didn’t hesitate. He pulled himself from Elara’s spasming heat and in one brutal motion, drove into Blythe from behind. She was tighter, less yielding, and she screamed, a raw sound of pleasure-pain that was swallowed by the train’s noise. He held her hips, pounding into her with a ferocity that spoke of escape, of trying to fuck away the ghosts that always followed him.
Elara, slumped beside them, watched through a haze of aftershocks. She saw the raw, animalistic need on his face, the way his eyes were shut not in pleasure, but in something closer to agony. He was using Blythe, fucking her like he wanted to break them both apart on the anvil of this sin.
Blythe met every thrust, her cries becoming rhythmic chants. “Yes… fuck… just like that… God, yes…” Her hand snaked between her own legs, fingers frantic on her clit. “I’m coming… I’m coming on your cock…”
Her body clenched around him, a second, violent convulsion. It tipped him over the edge. With a final, wrenching thrust, he buried himself to the hilt and froze, a ragged, wounded sound torn from him as he emptied into her.
For a long moment, the only sound was the train. Then, the heavy, uneven sound of their breathing. He withdrew, and Blythe sank to her knees on the velvet, trembling. Snape fell back into the seat, his trousers around his thighs, his body glistening with sweat, exposed and spent.
Elara reached for a throw blanket, pulling it over her own legs. The sudden intimacy felt more violating than the sex. They had seen the machine break. The polished, controlled Potions Master was gone, replaced by this raw, hollowed-out man staring at the ceiling as if he could see through it to a hell of his own making.
Blythe, ever practical, found a cloth and cleaned herself with shaky hands before pulling her skirts down. She looked at Elara, then at Snape. The calculating gleam was back. “Vienna,” she said, her voice surprisingly steady. “Is that where we’re getting off?”
Snape closed his eyes. “No.” He swallowed, the motion visible in his long throat. “We change trains in Munich. The destination is a house. In Switzerland.”
“A house?” Elara asked, the new information a pinprick of light in the post-coital gloom.
“A private residence. Isolated.” He opened his eyes, and the familiar mask was sliding back into place, but it was cracked, the anguish still bleeding through the seams. “Where the… containment… can be evaluated. Without interruption.”
He stood, fastening his clothes with swift, efficient motions, turning his back to them as he stared out at the speeding darkness. The message was clear. The interlude was over. The controlled simmer was resumed. But the potion in the cauldron was now something volatile, unknown, and the heat was still on.
