"M-Mephisto~!", (Y/N) let a breathy moan as fangs pinched the soft flesh on the queen's slender neck. A brown gloved hand proceeded to slide down from (Y/N) flushed cheek to her breast. The (H/C)nette let out a lewd moan after he had squeezed the mound. He placed one last kiss on (Y/N) neck before resting his hand on the girls shoulder. His hand massaged her breast while a devious smirk came upon the demonic gods features. Her body slumped down onto the mattress with a smirking demon hovering over her moaning form. His emerald green eyes sparked with excitement while watching the girl moan underneath him. (Y/N) could feel her husband's boner press against her thigh as he sat on top of her. Taking off the brown glove with his teeth, he slid his bare hand up her thigh before rubbing the wet stain on her black panties that had red and green peppermint candy canes scattered on them.

"M-Mephisto...! D-Don't... This is so embarrassing...!", (Y/N) breathed out as she brought the plush purple stripped Christmas ornament pillow to her red stained face. The libertine pulled the pillow out of (Y/N)'s grip and flew to an unknown part of the room.

"Don't hide, darling. You're doing great. Let me see that look you make every time I made you feel good~", Mephisto whispered into her ear softly. (Y/N) whimpered as his moist red tongue glided in her ear before biting the sensitive earlobe with his teeth.

His hand slipped underneath her panties. Mephisto's fingers became wet as they rubbed against her clit. He sent her a small smile to try to comfort her. Her wide (E/C) at her 1000+ year old husband with a look of uncertainty. After all, this was her first time having sexual intercourse with anyone. When (Y/N) had met Mephisto on the first day she joined cram school, she never once thought that she would ever have sex with him. Let alone date him. He was her principal and a demon king. She may be a 200 year old vampire but (Y/N) was only a fledgling when she met her Mepphy. Fledglings were lowest class members in the demon community due to their lack of skills and social status compared to other demons who lived longer in the world. She always thought Mephisto would be disgusted by her. Mephisto proved the female fledgling wrong the very moment he proposed to her.

"Mephisto!", (Y/N) was brought out of her train of thought when the demon king had thrust two fingers into her wet entrance.

"Yes, my love, scream my name! Let everyone know who is pleasuring you~", the king of time groaned out towards the moaning vampire while he pleasured her.

He kissed her hungrily while her hands tried unbuttoning Mephisto's red Santa shirt. His thumb played with her clit while constantly pushing his fingers in and out of her. She shrieked as his fingers hit a spot inside (Y/N) to make her vision white. Her muscles that reside around her stomach tensed.

"M-Mephisto... W-What's happening...?! I fe-eel s-so much pressure...!"

This feeling tightening in her stomach made (Y/N) terrified since she was still unexperienced with all this. As mentioned before this was the queen of time's first time having sex with someone. Mephisto knew of that. Usually he would have gotten straight to the point like he did with most women he had slept with, but Mepphy loved this woman too much to use her as blow up doll. He wanted this to be the most pleasurable moment that she would look back on and fond over for many years. Mephisto's undying love for his wife who he identified as a tsundere encouraged him to cherish every moment with her. Even if (Y/N) never knew how much the 2nd most powerful demon king loved her, Mephisto would try his hardest to make (Y/N) see the glorious and honorable position she currently held. Mephisto wanted her to know that she was no longer a low class citizen of that everyone was ashamed of in Gehenna. No, (Y/N) was worth so much more than most demons egged on. (Y/N) was the queen of time and now the queen of all vampires. And most of all, she was his soulmate and his treasure. Anyone who dared take (Y/N) away would have to suffer Mephisto's wrath. Yes, the king of time will surely enjoy the agonizing screams of pain of those whom he would torture and claim as threats to his relationship with his queen of time.
