Both obsessed/Tom Riddle (completed)

048. Nagini

The air in the Malfoy Manor was suffocatingly still, broken only by the occasional crackle of dark magic that still lingered from Tom's ritual.

The transformation had been a success Ernesh, no longer confined by the fragile mortal body that had been nearly destroyed by Dumbledore's treachery, now lay before Tom in the form of a massive, radiant serpent.

Nagini.

A creature of pure magic, eternal and unyielding, with dark green scales that shimmered like emeralds in the low light, and eyes that burned with hunger and devotion.

Tom leaned back in his chair, observing the creature with a mix of triumph and awe. He ran his hand along the smooth, sleek surface of Nagini's head, marveling at the power that now radiated from him. "Magnificent," Tom murmured, his voice low. "You're truly mine now, Ernesh. In every way."

Nagini coiled slightly, its enormous body shifting to wrap around Tom's legs. But there was something deeper than animal instinct in the creature's movements—it was still Ernesh, bound to him not just by the magic that had created this form, but by a love and obsession so intense that it defied mortality.

Tom leaned down, placing his forehead against the snake's head. "You can change back, you know," he whispered. "You don't have to stay this way." The incantation he had used allowed Ernesh to return to his human form whenever he desired, but it came at a cost. Transforming back drained him, leaving him vulnerable and weak, and the only way for him to replenish his strength was through Tom's blood.

It wasn't a drawback that bothered either of them.

For now, Ernesh remained in his snake form, his massive body coiled protectively around Tom as the dark wizard began to plot their next moves. They would retreat for now, as Dumbledore's letter demanded, but this so-called truce was temporary. Tom didn't retreat; he regrouped, rebuilt, and prepared for war. And this time, with Ernesh's new form and power, Dumbledore's forces wouldn't stand a chance.

Three nights passed before Ernesh transformed back into his human form. Tom had been sitting in his study, quill scratching against parchment as he finalized plans to consolidate their forces, when he felt a familiar presence behind him. Turning in his chair, he found Ernesh standing there, his human body restored but clearly drained. His skin was pale, his dark green eyes half-lidded with exhaustion, and his hair was slightly disheveled. He wore one of Tom's robes, the fabric draped loosely over his slender frame.

"You should be resting," Tom said, though his tone was softer than usual. He stood, crossing the room in a few long strides to reach Ernesh.

"I needed to see you," Ernesh murmured, his voice low but firm. He swayed slightly, and Tom caught him by the waist, steadying him. "I feel...weak."

"You just transformed," Tom reminded him, brushing a strand of hair out of Ernesh's face. "You need to recover. Come." He led Ernesh to the bed, laying him down gently before sitting beside him. "You know what you need."

Ernesh nodded, his gaze locking onto Tom's neck. His fangs elongated slightly, and his tongue flicked out, tasting the air. The sight sent a thrill through Tom's body, though he remained still as Ernesh leaned forward, his fangs sinking into Tom's neck with a practiced ease. The sensation was both sharp and intoxicating, and Tom closed his eyes, letting out a low sigh as Ernesh began to drink. The pull of his magic, intertwined with the venom that laced Ernesh's bite, sent a wave of heady pleasure through Tom. It was like nothing else—an intimacy that went beyond the physical, a connection that bound their souls in a way words could never fully express.

Ernesh drank deeply, his hands clutching at Tom's robes as though he feared he might disappear. Tom could feel the desperation in his grip, the need that drove Ernesh's every action. This wasn't just about survival—this was obsession, devotion in its rawest form. Ernesh would drain Tom dry if allowed, not out of malice, but because he couldn't bear the thought of anything separating them.

"Easy," Tom whispered, his voice a low command that sent shivers through Ernesh's already trembling body. He ran his fingers through Ernesh's hair, the silky texture against his palm enough to draw a faint groan from the creature-turned-man.

The moment Tom's fingers threaded through his hair, Ernesh let out a low, guttural sound that was almost feral. His body reacted instantly, his need intensifying as he pressed closer, as though he could melt into Tom entirely. The blood he took from Tom wasn't just nourishment—it was a form of possession, a way to ensure Tom was his and his alone.

"Marvolo," Ernesh murmured against Tom's neck, his voice muffled but dripping with longing. His fangs retracted as he licked the wounds closed, his lips lingering against the skin. "You're everything. My everything."

Tom smirked, pulling Ernesh's head back by his hair to force their eyes to meet. "And you're mine, Ernesh," he said, his tone sharp but filled with a dark kind of affection. "Don't ever forget that."

Ernesh shivered, his dark green eyes dilated with a mix of exhaustion and desire. "I couldn't if I tried," he whispered, his voice cracking slightly.

Tom leaned down, brushing his lips against Ernesh's in a kiss that started slow but quickly grew heated. Ernesh melted into him, his hands tangling in Tom's robes as he tried to pull him closer, as though proximity alone could satiate the all-consuming need he felt.

The two of them fell back onto the bed, a tangle of limbs and whispered promises. Tom didn't stop Ernesh when he moved to kiss his neck again, to mark him, to remind himself that Tom was his and his alone. For hours, they stayed locked together, their obsession feeding off one another, an endless cycle of devotion and desire.

For the next few days, Ernesh stayed in his human form, unwilling to separate himself from Tom even for a moment. The transformation had taken a toll on his body, and though he tried to hide his weakness, Tom could see it in the way Ernesh clung to him, the way he leaned on him more heavily than usual.

"You need to transform back," Tom said one evening as they sat in the study, Ernesh curled in his lap like a cat. "You're draining yourself too much."

Ernesh shook his head, his face buried in Tom's chest. "I don't want to," he murmured. "I don't want to leave you."

Tom tilted his chin up, forcing Ernesh to look at him. "You're not leaving me," he said firmly. "You'll never leave me. But you need your strength."

Ernesh hesitated, his eyes flickering with fear and reluctance. "Will you stay with me?" he asked, his voice barely above a whisper.

"Always," Tom promised.

With a deep breath, Ernesh closed his eyes and began the transformation. His body shimmered with dark magic as his human form gave way to the massive serpent once again. The process left him drained, his movements sluggish as he coiled around Tom's chair.

Tom rested a hand on Nagini's head, his fingers tracing the smooth scales. "You'll always have me, Ernesh," he said softly. "And when you're ready to change back, I'll be here to take care of you."

Nagini hissed softly, his massive body tightening around the chair in a way that felt protective rather than threatening. Even in this form, Ernesh's devotion was palpable, an unbreakable bond that tied him to Tom in ways that went beyond magic.

And as Tom sat there, his mind already turning to the plans he would make for their future, he couldn't help but smirk. The wizarding world thought they had seen the extent of his power. But with Ernesh by his side, they hadn't seen anything yet.
