Y/N couldn't believe that her fate has yet to come so soon. After like months or years of searching for her missing friends and her brother, she was horrified to see them all chained up, hurt, and more that she'd rather not explain what she just saw. She realized it was all Mephiles' doing much to her shock that he's supposed to be dead. Y/N managed to break everyone out, but was soon caught by Mephiles. She demanded to know how he's still alive as he told her that he has separated from Iblis and reformed just in time to survive the destruction of Solaris after the four super hedgehogs defeated it. He captured the heroes one by one and hauled them off to the mansion he made in his shadow dimension Y/N had discovered. Let's just say he enjoys torturing them and it angered her.

Their battle shook the dimension as she tried to take him down with all of her powers, but Mephiles was too powerful thanks to the defeated heroes that gave in. Y/N was sadly defeated as Mephiles was about to take her friends and her brother back to him when she begged him. This caught his interest as Y/N told him to let them go and to never go near them again or hurt them. Mephiles then told her that shock everyone as he told her that he will let them go, only if she stay with him forever and become his sex slave. She sadly accepted the deal much to her friends' dismay, especially Sonic as they beg her to not be with him. Y/N cried that she doesn't want to see them hurt and couldn't find another way. She'd rather give herself up to save them.

They were saddened to this deal they've made as it clearly satisfied Mephiles as they bid their goodbye to Y/N and promise her that they'll find the way to bring her back before they were teleported back home. It's been years since she became his slave.

In the dark room, Y/N lay all naked on the bed her hands tied up above her head to a bed post along with her legs that were spread wide enough to show her pussy. The door opened to reveal a smirking Mephiles who now has a mouth as he closed the door behind him. He slowly remove his gloves and shoes along with the limiters.

"Feeling comfortable, Y/N?~"

Y/N said nothing and struggled to get free as Mephiles comes closer.

He teleported right in front of her and slammed his lips onto hers. Y/N clenched her eyes shut as Mephiles forcibly kiss her. Tongues collide together with loud slurps and moans. Then, they pulled away with a string of saliva as he dug his teeth into her neck gently, placing a knee between her legs.

Mephiles sucked on her neck, making Y/N moan weakly, squirming in his grasp and trying to suppress it. He began to playfully rub his leg into her pussy, causing her to mewl loudly. He pulled away with his dark green eyes scanning her body before he leaned down and bite her neck sharply, rolling the skin between his teeth. Y/N yelped in a high pitched shocked tone, causing Mephiles to growl in satisfaction. He pulled away and gently licked her neck, and roam his hands around her naked body as he began to massage her breasts while pinching her nipples.

"Come on, Y/N~ Just give up and this whole thing will stop."

Y/N shook her head.

"N-No! Ngh..!"

Mephiles chuckled at how stubborn and cute she is.

"Then you leave me no choice."

She turned and her eyes widen when he pull out a gag ball. He grabbed her chin, forcing her jaw open and shoved it in her mouth and strapped it tightly. Y/N quivered as the dark hedgehog sit back to admire her shaking form and leaned over the foot of the bed and pressed his nose to her thigh. A wicked smile curling on it as he mockingly licked all the way up to her clit. He didn't touch it however, he watched her face as she looked away, frightened. He let out a deep chuckle which made her look back at him.

"Watch or I might make this hurt more than it has to."

Y/N quivered staring him directly in the eyes that looks as if he's about to devour her as he slowly slide his tongue from his mouth and licked directly between her pussy lips spreading them with his tongue and going all the way up slowly.

Y/N shuddered as he kept licking up to her slit with each slide. After a few licks, he began to focus on her pussy itself as he lick that spot roughly whilst he maintained eye contact, which she was barely able to do as she shuddered and twitched. The licking felt good but she didn't exactly want this nor admit it!

Mephiles smirked a bit and Y/N couldn't watch him any longer her head turning away and eyes shutting tightly. If she'd remained watching maybe she would've seen his eyes flash in excitement. She felt his weight on the bed shifted then his entire mouth pressed against her pussy before his tongue thrust inside of her. Y/N gasped into the gag looking at him again. He was on his hands and knees on the bed between her legs with his tongue pressed inside of her and slithering around, his eyes locked on hers now they were open. He stop to smirk then pulled his tongue out planting a sloppering kiss on her clit.

Y/N closed eyes shut and whimpered again, feeling at the mercy of the dark hedgehog. He shifted on the bed this time moving over top of her.

"You best be a good girl~" he growled sexily in her ear before he thrust into her slowly, letting her feel each inch of his cock sink slowly into her.

Y/N dug her teeth into the gag till her jaw hurt. Mephiles groaned in satisfaction as he thrust into her. Deeper and harder now he'd got a good amount of his cock inside of her. Y/N squeaked loudly when Mephiles grip onto her hips suddenly and pull all the way out. She opened her eyes as she thought he was done when Mephiles showed his fangs that glittered and he thrusted into her harder than before. He had a massive grin on his face as his own eyes were now shut. Y/N moaned loudly into her gag as she helplessly watched him thrust into her pussy.

Mephiles growled loudly as he increased his speed. She could feel his dick press deep into her pussy and hit her good spot, making her jolt and moaned even louder and shrilly.

"You obey well. Time for a prize."

He pulled out of her and untied her legs and shoved them up so they were by her head. It wasn't a comfortable position, but she quickly learned why he did it when he thrust back into her and slammed her good spot roughly it made her moan and whimper, biting the ballgag hard it had holes were her teeth had punctured the rubber with how hard she was fighting it but she couldn't fight her body. With a pathetic winded moan, she came on the dark hedgehog's dick as he growled and kept thrusting.

Mephiles' breathing had increased notably, alone his speed till all she could feel was pleasure, her pussy muscles clamping and sucking at him as she was almost as if she was on sex drug with the hard fucking. Mephiles suddenly buried himself deep into her, gripping her waste to make sure she couldn't squirm away he came into her, it triggered a second organism basically on top of the first and she sagged, jaw sore from gripping the ballgag.

He undid the gag and set it aside before lean down and kiss her deeply. Y/N's eyes went shut considering what she was doing carefully before kissing him back. She could feel him smirking through the kiss and they pulled away with small pants.

"I'll make sure none of the others even reach you. You're all mine."

He then lay down beside her as his face is burying into her chest.

"If you behave, I will treat you well like a queen. Understood?" he murmured.

Y/N panted and slowly closed her eyes, feeling tired not before replying.

"...Yes... Master."

Mephiles smiled in joy that she finally gave in before they both fell asleep not before he use his dark magic to make the blanket move to cover their bodies.
