Mc is female, this is not proof read.
Mc had recently gone to a party with Asmo. The last thing she expected was for the hosts to give fondue sets to all attendees. The human had no idea what to do with such a thing. Maybe she could gift it to somebody? Or sell it? But then, she got a good idea. Since it was one of Asmo's parties, the hosts surely weren't handing out fondue sets for any other reason than sex right? At least, there would be a high possibility of them having such intentions. So, Mc put some chocolate in the pan, and took it to the twin's room, when Belphie would be napping in the attic, of course. It was the sixth born she wanted to surprise after all.
'Mc, I got every chocolate we have-' Beel's words caught in his throat when he saw Mc, delicate and naked on his bed in the dimly-lit room. She was busy dripping some of the melted chocolate onto her breasts from a spoon. The demon felt his pants becoming tight at the view and closed the door behind him. 'Thanks, we can put them in the pan.' Mc replied, in an ironically innocent tone. Beel scanned the room once again. 'So this is why you needed so much chocolate.' he noted as he moved closer to the human, staring holes into her chest. The way the melted substance flowed along with her curves down her stomach, how it slightly dripped onto the sheets. It was all to exciting for him. 'Can I?' Beel asked and Mc nodded. Immediately, the avatar of gluttony took a breast against his lips and started cleaning the chocolate off, while freeing himself from his own clothes until he too was fully bare. Mc let out a little whimper every time Beel would lick or bite down on her now hardened buds while he would let out a low groan from the back of his throat. Once he was done with the ambush on Mc's chest, he grabbed the spoon from the pot and dripped some of the chocolate onto it again. 'That was delicious, I need more.'
As she watched the thick liquid hit her skin, she scraped some of it off with her finger and applied it on her lips. 'Oh, I made a mess, will you clean it up?' she teased lightly. Unsurprisingly, Beel dropped the spoon back into the pot and kissed Mc on the lips. The kiss was sloppy, mildly violent, filled with pants and gasps, but is was one of the greatest kisses the couple shared. In the process, Beel was rubbing his ripped body against Mc's, causing the chocolate to smear all over both of them, as well as the sheets. But,they didn't care. They were too into their love-making session to bother about the mess. The best part about this all was the warmth of the chocolate. Having a hot substance hit her skin was like a portal to a new dimension of pleasure to Mc.
When the pair was done making out and catching their breaths, Beel pushed Mc farther into the sheets. 'I can't wait anymore, are you ready?' he said as he propped his large lenght against the human's core. Mc nodded, and Beel instantly pushed in a bit. The burn from the stretch made Mc writhe and moan out already, even though it did hurt. This worried the avatar of gluttony. He bent down a bit to Mc's level and hugged her smaller frame around her shoulders. 'Are you okay? Want me to pull out?' the demon questioned. Mc shook her head. Beel would ask the same question during every sex session they had, which would always be sweet of him. 'No, it's good.' she got out between pants. After letting the human get used to his size, Beel pushed his whole cock in. A clear bulge was visible on Mc's abdomen, right where the sixth brother was inside of her.
Everything felt great. Both partners filled the room with broken moans and occasional groans until they felt an orgasm coming. 'I- inside.' Mc got out and Beel got the message. The demon arched his back, causing his muscles to flex as he released his sperm inside of Mc. This cycle went on and on for a while, long enough for The human's stomach to swell up slightly from all the cum. Beel was about to reach for the fondue pot again, but then he heard the door click. He stopped dead in his tracks what he was doing, getting a confused reaction out of Mc. 'Beel? What's wrong?' she asked, an undertone of worry in her voice. Beel looked down at his partner under him with wide eyes. '...I closed the door, but I didn't lock it.' Now, Mc's eyes spread wide like saucers too. 'Oh no...'
There Mc and Beel laid, in full view for whoever just opened the door. The blanket was jumbled up, left forgotten on the corner of the bed. A fondue pot on the floor, filled with hot chocolate. Smears of said chocolate all over the sheets, and the floor next to the bed. And, the grande finale, Beel and Mc nude and still connected, with hickeys and chocolate smears all over their bodies. '...I can't even walk into my own room without problems.' a voice behind the couple spoke. Beel's blood ran cold, the unlucky one was Belphie. The avatar of gluttony quickly pulled out and tried to cover Mc with his shirt that was on the floor within reach. 'Belphie, I'm sorry I should have locked the door.' Beel apologised to his younger twin. Meanwhile, Mc was sinking through the sheets out of shame. 'Don't look...' she whispered loud enough for the seventh born to hear. Belphie stared at the floor. 'Put some clothes on, you two... And we'll act like this never happened.' he said, but he was clearly traumatized from what he saw. Beel covered himself up quickly with the blanket before speaking. 'We're sorry, Belphie. I'll get you five pillows to make up for this.' The younger twin let out a breathy chuckle. 'Fine, apology accepted.'
