His mouth was on hers. Kissing her. Slowly, gently. Without hesitation, she kissed him back. This was him. The boy she loved. The kind and innocent demon slayer who taught her to follow her heart and make her own decisions. She closed her eyes and savored this moment that seemed so much like a dream. He was finally here. After years of being apart he was back. He came back for her.

But her musings stopped when she felt a searing pain in her bottom lip. He bit her and she tasted the metallic tang of blood in her mouth. She was snapped out of wonderland when she opened her eyes and she was met with blood red pupils gazing back at her with the unmistakable look of lust. This was not her Tanjirou. This was the demon God Muzan had created.

She tried to reach for the sword that was forgotten on the floor but he was faster. With one hand, he pinned both of her hands behind her and she could feel his sharp claws digging into her wrists. She watched as he picked up the sword and threw it to the other side of the room. "We won't be needing that right now."

She tried to fight back but found that even that was futile for he tied her hands behind her.

He kissed her once again but this time, with newfound haste and passion and a roughness so unlike the boy she knew. And yet, she still kissed him back. She kissed him back despite the acrid taste of blood on her mouth. The blood that was hers. She kissed him back despite knowing that the one in front of her was no longer a human but a demon. Because despite that, she still loved him. She was his the moment he offered that coin back to her. And what could she do but submit to her true master?

She couldn't help but moan when he squeezed her breasts and he smirked as his hand traveled underneath her skirt. His hand moved to her center and he suddenly inserted his fingers into her wet hole that she shrieked in surprise. He furiously fingered her pussy until she came. He finally let go and her knees buckled immediately that she fell on the floor panting and hips still shaking from her prior orgasm. Tanjirou smiled as he towered over her kneeling figure. He parted her lips with glistening fingers. "Lick it, Kanao. Taste yourself."

Like a hungry animal, she licked his fingers clean.

Tanjirou smiled at her obedience and patted her head. She purred in response.

"Now, are you ready to suck on something much bigger?"

She looked up and came face to face with his hard dick. Without hesitation, she took him into her mouth. He groaned at the sight of the inexperienced girl trying to take his whole engorged cock in her mouth and put his hands on her head, locking her in place. She moaned at the sudden movement from her master.

"You like that, huh? You like it rough, Kanao? I'll show you rough."

Without warning, he thrust deeper into her mouth. She gagged at the large object forcefully making its way down her throat but he just smiled and carried on.

"Oh fuck, Kanao. Your mouth just feels so good."

She didn't know why, but hearing Tanjirou curse and talk dirty only served to arouse her more. She could feel her wetness pooling at her core. He moaned as her teeth scraped against the skin of his sensitive cock and tightened his hold on her hair, thrusting in deeper and fucking her mouth with more aggression.

"Now you will see, Kanao. I'm gonna make you experience something that will shake all your breathing of total concentration."

Tanjirou thrusted his entire length into her mouth, tip to base and began to rapidly grind on her face. He looked down, his huge dick had created a bulge in her throat and precum had spilled out and pooled at her lips. The sight of her face as she tried to steady her breathing and still continue sucking his full length drove him into madness. The demon in him was eager to spread his seed. He let out a cry of pleasure as he roughly fucked her face, his balls slapping against her chin. The sound of his balls slapping against her face combined with the look of pleasure clearly seen on her face was enough to make him lose it. He came in her mouth, making sure she swallowed every single bit.

"Hmm, did you enjoy that, Kanao? Or are you still gonna try to fight this? You know there's no running away, right? You're mine now."

Kanao shook her head. Still gasping and panting from their previous blowjob session, she tried her best to answer as coherently as possible.

"I-I won't try to fight back again. You are my master. I would do anything you asked of me."

"Prove it then."
