You sit up straight, trying desperately not to break out into a cold sweat and give away just how absurd and inappropriate your current situation is. You were supposed to have a short meeting with Diavolo concerning a few questions he had about your comfort in the Devildom, but…
Barbatos' long, rough tongue drags along the sensitive little bundle of nerves between your legs. Each bump and ridge brings a new sensation that makes your thighs twitch involuntary. All you can do is keep a straight face and continue looking forward at the man speaking to you from the doorway, hoping he hasn't caught on to anything that would embarrass you to explain.
"-man realm dishes?"
"I'm sorry," your voice breaks a little and you clear your throat, both to recenter yourself and to request Barbatos give you just a moment's reprieve, "Could you repeat that?"
"I asked if you would like it if we added some more human realm dishes to the cafeteria menu. You're probably tired of Devildom food." Diavolo looked down at the paper in his hands, clearly trying to read something.
The butler looks up at your face from just below the desk where you sit, noticing how the edge of your mouth pulls ever so slightly with each lap of his tongue. You are staying so wonderfully composed despite yourself. A small part of him is proud of you, but an even smaller part is tempted to ruin that composure; a part that, to your misfortune, is rather boisterous in its desires.
He pulls a single glove from his hand one finger at a time before stripping the entire thing off and letting it fall to the floor; if he was going to ruin your carefully maintained facade, he was going to do it without letting anything come between him and you. Two now ungloved fingers reach up, just barely pressing between your wet folds as he begins to slowly stroke your willing entrance. Only once he is satisfied with how slick you've become -- practically gushing just from a little teasing -- does he push two fingers into you, nearly finding himself chuckling at how eagerly your body stretches to welcome him inside.
You jump in your seat at the feeling of cold skin brushing against your warm inner walls as his tongue continues its ministrations.
"Are you okay?" Diavolo asks.
"Mhm!" You dare not speak, afraid of what noises will come out the second you open your mouth.
"Oh, well, about the human realm food-"
His voice fades off into the distance as the roughness of Barbatos' tongue is replaced with the softness of his lips against your clit. Inside of you, his fingers press against a spot that makes something inside of you jolt forward like a bottle that has built up too much pressure and is only moments from exploding.
Fuck! You don't want to cum in front of Diavolo.
"Sounds good!" You say in a panic, hoping he doesn't hear the lust in your voice.
"Excellent. What dishes would you like us to look into?"
Oh for the love of, "I can tell you a few later, okay?" Just leave so I can cum already.
"Are you sure?"
Barbatos removes his fingers from your heat, letting his mouth trail lower so his lips are pressing against your slick folds. He lingers there, seeming to content himself with kissing your lower lips the same way he would your upper ones. That moment passes quickly, however, as his tongue reaches out, pressing into your cunt until your arousal drips against the appendage that continues slipping further and further into you. It feels as if it will go on forever. Each coarse, glutinous inch that sinks deeper in teases your very core, leaving your insides dripping with both your wet and his saliva, and you have to fight not to groan and beg him to fuck you just like this even if the prince is right there.
"I'm sure." You smile, even as your voice is threatening him as politely as it can.
You aren't sure if he finally got the hint or if he just didn't have anything else to say, but he nods to you, "I should go find Barbatos and Lucifer so we can talk about how to implement this. Thank you for your time." He flashes you one of his trademark grins before closing the door at leaving you alone.
As soon as you hear the click of the door closing behind him, you slouch into your seat and finally let out the moan you'd been holding back, uncaring how loud it was once it was free, "Fuck, yes. Barb, I'm gonna cum!"
He says nothing, but his tongue continues to move in and out of your willing heat. You swear you can feel it scraping against your deepest parts, every little bump pushing you closer toward your final release -- which comes all too quickly.
Your legs shudder as you finally feel your orgasm overtake you. Barbatos remains inside of you, tasting each wave of pleasure that wracks through you because of him and reeling in how your walls clench around his tongue as if pleading for more. Only once your trembling stops and you quiet does he pull out, licking away the remnants of your orgasm from around his mouth and your slick from off the fingers that had been pleasuring you.
He's the first to speak, "I apologize, my dear, but it seems that the young master will be in need of my assistance." He picks his glove off of the floor and puts it back on, "If you do not mind, I will attend to him now."
"Barb…"
"Do not fret, my dear. I will return as soon as I am able. Until then," he takes your hand in his, placing it between your legs, and pushing two of your fingers into your wet hole, "do see to it that you stay ready for me."
