The demon sighed as he watched the human beside him, pink hair strewn across their face as they snored softly.
Belphegor watched him. He had an hour before the spell had worn off. He’d been unaware of it beforehand, but his sin affected those around him when he fell asleep. He hadn’t realized its extent until he was jerked awake by his brothers shouting in the living room when MC collapsed. The human was sound asleep, despite Mammon frantically shaking them.
He made sure to fall asleep in the attic more often, irritating the hell out of him as he couldn’t doze off or risk MC cracking their head open.
A month later, MC had knocked on the attic door, shifting nervously. They looked horrible. “What’s wrong?” He asked, surprised the human came to him.
“I can’t sleep. I’m having some bad nightmares. Could I maybe sleep with you?” They asked cutely. Or maybe it wasn’t meant to be cute and MC was just inherently cute. Either way, the demon agreed and let them in.
MC was out cold after he himself had dozed off. His dreams, however, were filled with MC and the thought of them against his body. He woke up to his cock twitching to life.
An hour. He had one hour before the human woke up. He pulled himself out as he glanced over at MC’s peaceful expression. He licked his lips and pumped himself slowly, working himself up as he studied their lips as MC hummed softly in their sleep.
Belphegor groaned as he bit his lip. He did have an hour. There was no way the human would wake up.
He licked his lips as he moved, pulling MC’s legs up. He was so damn glad the human wore shorts as he slicked up their thighs before pressing them tight around his cock. He thrust slowly as he fucked their thighs, relishing in the feeling of the warmth around his length.
Fuck he’d get his guts pulled through his mouth if Lucifer found out what he was doing. If the eldest sibling realized he was fucking their thighs while they were unconscious, he’d be locked in the attic all over again.
He reached down and shoved the shorts aside, rubbing his length along their folds. He groaned as he felt their heat.
“Oh fuck yes,” He moaned as he rutted hard against them. “Fuck, don’t you dare wake up.” He pushed in slowly, grunting as he spread them open slowly with his length. His nose twitched as he caught the vague scent of blood. “Fuck, sorry,” He groaned as he pressed their knees to their chest. “I’ll take good care of you later. Just stay asleep for me, human,” He moaned, thrusting hard into them.
He looked down at their sleeping form, seeing a small trail of drool slipping from the corner of their mouth. Out cold.
Belphegor moaned and pushed deeper as he picked up the pace.
The way the human flaunted about the House of Lamentation left Belphegor aching more times than he’d like to admit. The stupid human thought they were safe with him. Safe, they’d always be safe under him, he decided as he adjusted so he was practically folding them into a mating press.
“Mine,” He snarled as he shifted forms, gripping the headboard and thrusting harder. The bed creaked loudly under his thrusts. His tail flicked angrily as he felt the wall they clenched around him. “That’s it. Fucking squeeze me, human,” He spat. “MC.”
He groaned as he reached down, rubbing their clit roughly as he fucked into them faster. A smirk spread over his face as he moaned, feeling them slicking him up as their body gave in and orgasmed. “So good for me. I’ll make your body crave me.”
Belphegor watched their sleeping form and checked the time. He still had forty more minutes to do as he pleased.
He smirked as he pushed deeper, feeling his cock twitch as he kissed their neck. “I’m going to make you mine.”
