“Private” Group Chat

{CW: Somno/ Mentions of Fingering, Masturbation and Threesomes/ Slight Body Worship/ Sharing nudes/ GN! Poly! SUB! MC }

Just thoughts of the demon bros + datables (Minus Luke) having a private group chat to just send each other your nudes and share videos of how they each made you feel good

•Beelzebub/Diavolo shares videos of him and Belphie/Barbatos tag teaming you

•Solomon sends multiple videos of him eating you out/sucking you off so loudly and sloppily

•Lucifer sends pictures of you bound and gagged, thrusting into you with a steady pace as your whines and moans were muffled but still able to be heard in the video

•Satan sends a video of him fuckin you so roughly while your pretty lilac bell collar jingles at each of his thrusts

•Asmo and Mammon send adorable separate pictures and videos of them kissing your thighs and neck while slowly pumping their fingers into you

•Belphie sends solo vids/pictures of him fucking you so slowly when you and him (and sometimes Beel) sleep in the attic together

•Thirteen gloats about you taking her fingers so well and how you dress up for her so prettily but never sends pictures because that’s only for her eyes to witness

•Raphael and Mephistopheles never respond but they definitely do save all the pictures/videos sent in the gc for another time

•Poor Levi and Simeon are flustered and embarrassed about all this but are so definitely pumping their cocks/humping a pillow to the pictures/videos the others are sending of you in the chat

But because of your DDD, You know all about your boys’ little “private” group chat and you occasionally whine a little louder or position yourself a little too perfectly for the camera angle.

The boys are completely unaware… Except for Lucifer and Diavolo who are suspicious of your “subtle” actions.

But both Raphael and Barbatos knows you know of their chat of course.

scientist!gn!reader x Leviathan

smut; you need a semen sample from the newly captured demon, but he has troubles giving you one. Why not help him out?

"I'll need a semen sample."

The demon looks at you, completely bewildered, and you can see the red on his face progressing as he processes your words.

"H-hell no!"

His voice is high, his hands nervously beginning to fidget. You can only smile at him while turning back to your computer, documenting his reaction.

"I'll, of course, give you some privacy. Please use this for the sample," you hand him a small, clear cup which had been sitting on your desk for some time now, "and let me know if you need something to get you going."

"Get me going?" Leviathan swallows heavily while accepting the cup through the magic bars, miserably looking at it.

"You know, like porn. You've heard of that, right?"

The blush on the demon's cheeks deepens as he bashfully nods, a hint of disappointment in his shy eyes. You've noticed the way he looks at you, reserved glances spared for your body when he wasn't just sulking in his cell, mumbling to himself, and you felt like it would be a waste not to take advantage of his small obsession.

He's only a demon after all, and you've had quite a few of those in these labs already. No one would care for a few hours of undocumented time spent with Leviathan. You consider all this while turning the cameras off and packing your important things to leave the demon to his business.

"You know which button to press if you're done... or need help," you add a wink to your last statement, and you barely see Leviathan's eyes widen before the high-security door closes before your eyes.

To your surprise, Leviathan does not call for your help, and the device on your belt is still silent after two hours. Out of worry, you decide to get back into the lab with his cell in it, opening the door slowly in case he was still at it.

Under the loud sound of the security deactivating for your entrance, you hear the hectic shuffling of clothes and loud sniffling before you're met with a fitting image. Leviathan is sitting in the corner of his cell, his jeans messily and barely pulled up to cover his crotch, and he's holding a turned hand in front of his shocked face, hiding some of the tears, which are clearly visible in his eyes.

You offer him a scolding look before telling him he could have just called you if something was wrong. He starts stuttering, pressing himself further against the wall when you squat down in front of his cage, moving to eye-level with him.

"What do you need, hm?"

The demon shakes his head subtly, the panicked expression in his eyes rising. "I don't know?" he squeaks, more tears falling.

You sigh while getting back up and slowly start opening the high-security door to his cell, confidently stepping into it. Leviathan looks up, and you can see the smallest bit of excitement building in his optics. You kneel in front of him, putting your hand on his pulled-up knee.

"C'mon, tell me what you need."

Leviathan needs a moment to comprehend the situation before letting his hands sink to the floor and legs fall apart under your slight push.

"B-be mean to me, please."

You chuckle a little while your hands move to his waist, squeezing the soft flesh before pulling his jeans down, revealing his otherwordly demon cock. Small ridges line the light blue-colored shaft, which bleeds into a dark marine tip, which is slightly bigger than his cock.

You've seen it before, during his basic anatomical documentation routine when he was first brought in, but touching it now feels entirely new. Your fingers explore the texture while you ask him if every demon has such a small cock.

Leviathan gasps at your statement, the sound followed by a whimper and his hips shyly pushing up into your grip. Your hand strokes his cock a few times, easily finding the sensitive sports and getting used to its shape. Leviathan's tears started flowing again, his cock sensitive and hurtful after two hours of trying to get off.

"You're such a pathetic demon, Leviathan," you smile, your fingers tightening around his cock; tightening to a painful degree.

He cries out, his hand gripping your wrist but not stopping you. His body shakes, and his face looks utterly ruined, red, twisted, and glistening by tears.

"Gonna cum from having your dick strangled?" your words are laced in gentle whispering, right next to his ear.

Your lips are suddenly on his, the surprisingly gentle kiss contrasting your nails digging into Leviathan's most sensitive parts. He whimpers into your mouth, the sound pitiful until he cums. His semen shoots out of his swollen cock, pulsating against the pain you're inflicting on him.

You quietly laugh at him for cumming from this, watching the blue gooey cum drip over his torso. As the demon comes down heavily breathing, you allow yourself to scoop some of his release into the sample cup you gave him.
