Snape and Lily's forbidden secret

James pushed open the front door of Godric's Hollow, exhaustion weighing his limbs. The mission had dragged on for days with no end in sight - dark wizards, cursed artifacts, the usual shit. Now that he was finally home, James just wanted a shower, a stiff drink, and his wife's embrace. The house was too quiet, however, for as late as it was, it didn't surprise him. No crackling fire, no Lily humming as she stirred a potion. Just the faint creak of floorboards upstairs. 'She must be getting ready for bed.' He thought as he climbed the steps, wand loose in his hand. Their bedroom door stood ajar, a faint light spilling into the darkened hall. Then he heard it - sharp, breathless moans. Lily's moans, but not the sounds she had ever made for him. These were deeper, rougher. A man's groan followed, unmistakably one he recognized from his Hogwarts years as a bully. That was Snape's voice.

James froze. His pulse hammered in his throat. Through the gap in the door, he saw them. Lily sprawled on their bed, her pale thighs spread wide, and a single candle illuminated the betrayal unfolding on their marriage bed. There she was—his wife, Lily, her fiery red hair splayed across the pillows like a halo of sin, her pale skin flushed and slick with sweat. Her legs were wrapped around the lean, dark-haired form of Severus Snape, James's lifelong enemy, whose sallow face was contorted in savage pleasure as he drove his thick cock deep into her dripping pussy with relentless thrusts.

Lily's back arched off the mattress, her full breasts bouncing with every brutal plunge, nipples hard and begging for attention. 'Yes, Severus, harder—fuck me like he never could,' she gasped, her voice a husky whine that cut through James like a curse. Snape growled in response, his long fingers digging into her hips as he slammed forward, his balls slapping against her ass with wet, obscene smacks. The bedframe groaned under the ****, sheets tangled and stained from their frantic rutting.

James stood frozen in the doorway, rage boiling in his veins, his own cock twitching traitorously at the sight despite the fury. Snape's pale ass flexed with each powerful stroke, burying himself to the hilt inside Lily's clenching heat. She clawed at his back, nails raking red trails down his back, her moans escalating into cries as she neared the edge. 'I'm yours—fill me up, make me cum on your cock,' she begged, oblivious to the shadow of her husband watching their illicit union.

Snape leaned down, capturing her mouth in a messy kiss, tongues tangling as he pounded faster, the room thick with the musky scent of sex. James's mind reeled—how long had this been going on? The shock rooted him in place, even as a dark, twisted arousal stirred, watching his nemesis claim what was supposed to be his.

James stepped closer, the floorboard creaking under his boot. Snape's thrusts stuttered—he'd heard. Dark eyes flicked to the door, locking onto James with a smirk. Lily gasped, twisting to look. Her cheeks flushed deeper, but she didn't pull away. Instead, she hooked a leg around Snape's waist, urging him deeper.

"Don't stop," she panted.

Snape obeyed, slamming into her with a rough groan. The bedframe rattled. James could see everything—the way Lily's cunt stretched around Snape's cock, glistening with each withdrawal, the way her nipples hardened under his roaming hands. Snape dragged his thumb over her clit, making her cry out. "Tell him," he growled, fingers tightening on her throat. "Tell him whose cock you prefer."

Lily's gaze locked onto James, her green eyes hazy with lust. "His," she whimpered. "Fuck—*his*." James' cock throbbed in his trousers, torn between fury and hunger.

His grip tightened on Lily's hips, pinning her writhing body to the rumpled sheets. Snape's pace turned punishing, his hips pistoning, balls slapping against Lily's ass. He was teetering on the brink, his cock throbbing inside her slick, welcoming pussy, every vein pulsing with the need to release. Tonight was the night; the timing aligned with her cycle, and the potion he'd slipped into her tea earlier ensured maximum fertility. No interruptions, no mercy, he wouldn't stop now.

"Come for me," Snape ordered, voice rough. "Let him watch you fall apart on my cock." Lily's back arched, a scream tearing from her throat as she clenched around him. With a deliberate tilt of his head, Snape's dark eyes flicked toward the doorway, locking onto James Potter's furious gaze. There he stood, the golden boy, face twisted in rage and disbelief, wand half-raised but useless in his shock. A slow, triumphant smirk curled Snape's thin lips, his black eyes gleaming with malice and unbridled lust. Watch me claim her, Potter, his stare seemed to say, watch me breed the woman you thought was yours.

Lily, lost in the haze of pleasure, bucked beneath him, her inner walls clenching around his shaft as she chased her own climax. 'Severus! Oh god, don't stop, I'm so close.. I'm gonna come again,' she whimpered, her green eyes fluttering shut, oblivious to the silent standoff. Snape's hips snapped forward one final time, burying his length to the root, his balls drawing tight against her ass. He held James's eyes, refusing to break the connection, as the first hot spurt of cum erupted from his cock, flooding her depths with thick ropes of seed.

A guttural groan escaped Snape's throat, his body shuddering as he pumped load after load into her fertile womb, grinding deep to ensure every drop took hold. Lily cried out, her orgasm crashing over her, pussy milking him greedily, juices soaking the sheets. Her nails dug into his shoulders, legs locking around his waist to pull him closer, deeper. Snape's smirk widened into a sneer, his gaze never leaving James's as he marked her irrevocably, the air heavy with the scent of their joining and the unspoken victory.

His fingers dug into her hips, keeping her pinned as he spilled every last drop deep into her womb. Lily gasped, her thighs trembling around him. "Yes—fill me," she moaned, arching to take him deeper. James watched, transfixed, as Snape's release leaked from her swollen cunt, dripping onto their sheets. The sight sent a jolt of heat straight to his cock. Snape didn't pull out. Instead, he leaned down, lips brushing Lily's ear.

"You wanted this," he murmured, voice thick with satisfaction. "Begged for it. My seed taking root inside you."

Lily whimpered, her fingers clutching at Snape's robes. "I did," she admitted, breathless. "I wanted you to breed me."

James' jaw clenched. His cock ached, straining against his trousers. Snape finally withdrew, his cock slick with Lily's arousal and his own spend. He smirked at James, dragging his fingers through the mess between her thighs before bringing them to Lily's lips. "Clean yourself up, pet," he ordered. Lily obeyed without hesitation, sucking his fingers into her mouth with a moan. James' breath came ragged. He couldn't look away.

Severus straightened, his cock still glistening, thick and larger than James three times over. With a swift, practiced motion, he flicked his hidden wand toward James. "Obliviate."

James' eyes rolled back before he slumped to the floor, limp. Severus smirked, levitating him onto the bed beside Lily's trembling, sweat-slicked body. The Auror's robes were rumpled, his chest rising and falling in deep, oblivious sleep. Severus stepped closer, his cock already thickening again as he gripped Lily's hair.

"Finish what you started," he growled, guiding her mouth to his shaft.

Lily moaned around him, taking him deep, her tongue working along his length with practiced hunger. Severus fucked her throat in short, brutal thrusts, his hips jerking as her lips stretched obscenely around him.

"That's it—take it all," he hissed, fingers tightening. His balls drew up, pulse pounding as heat coiled low in his gut. "Swallow every drop."

She whimpered, her throat fluttering around him as he slammed in one last time. With a guttural groan, Severus came, thick ropes of cum spurting down her throat. Lily swallowed desperately, her lips sealed tight around him as he emptied himself into her. Severus pulled back at the last moment, his cock slipping free with a wet pop. The final spurt of his release arced through the air, splattering across James' Auror robes—a stark, glistening streak against the dark fabric. Lily panted, her lips swollen and slick, her tongue darting out to catch the last traces of him. Severus smoothed a thumb over her chin, smearing a stray drop of cum across her skin.

"Good girl," he murmured, tucking himself away with a satisfied sigh. He glanced at James' **** form, the evidence of his claim unmistakable. "Rest. You've earned it." With a final smirk, Severus swept from the room, leaving them both marked by his possession.

***the next morning***

James groaned as consciousness crept back in, his head throbbing like he'd been hit with a Bludger. Sunlight streamed through the curtains, casting golden streaks across the rumpled sheets—and the naked woman curled beside him. Lily. Her red hair fanned across the pillow, her bare shoulders rising and falling with each slow breath. The sheet had slipped low, revealing the swell of her breasts, the faint marks—*bruises?*—dotting her pale skin.

James sat up sharply, wincing at the twinge in his muscles. His own clothes were disheveled, his trousers half-unbuttoned, his cock still half-hard beneath the fabric. *What the hell happened last night?* He raked a hand through his hair, trying to piece together the gaps. Dinner. Firewhisky. Laughing with Lily—then nothing. Just blackness. And now this.

Lily stirred, her lashes fluttering as she blinked up at him. Her lips were swollen, her green eyes hazy with sleep—and something else. Satisfaction.

"Morning," she murmured, stretching lazily. The sheet slipped further, baring the curve of her hip, the faint stickiness between her thighs. James swallowed hard. "Did we—?"

Lily's smile was slow, knowing. She reached for him, her fingers trailing down his chest. "You don't remember?" Her hand dipped lower, brushing the bulge in his trousers. "Guess we'll have to refresh your memory." His breath hitched as her fingers worked his buttons open, her touch deliberate, teasing. *Fuck.* Whatever happened last night—he wasn't complaining.
