You knew what you were getting into when you entered a relationship with the Avatar of Lust - so, in all fairness, you should’ve seen this coming. How you ended up with your arms outstretched and your wrists to the headboard in handcuffs, and every inch of your body exposed and ready for the taking? Well, that wouldn’t require much - there never had to be a celebratory or punishing situation for Asmo to bound either your wrists or ankles. However, tonight was a little bit different.
Your arrogance had been getting the better of you - or so Asmo said, which you thought was pretty rich coming from him. But how was it possible for you to be so chummy and lovey-dovey with his brothers when you have a perfect, in every sense of the word, boyfriend who could give you everything you could ever want? Don’t you have enough?! You knew exactly what you were doing, too - like you could get away with it every time you rubbed shoulders with Levi while you were playing video games, or when you licked the frosting off of Beel’s thumb when you two baked together. The final straw was when Asmo saw you lean into Lucifer’s touch while the two of you were studying together.
In all honesty, you kinda thought you could get away with those little things. There’s no bigger flirt than Asmo himself, so you thought that you were okay to do the same. I mean, Asmo would never punish you for spreading love… right?
So, that’s how you ended up with your wrists bound to Asmo’s headboard, your naked body exposed to every single one of your boyfriend’s desires, and a mischievous and excited grin on his face.
“Oh, darling, look at you!” Asmo purred in-between kisses against your stomach, admiring the small shivers that coursed through your body at the sensitive touch. “You’re so pretty, my dear. And all mine to adore.”
Your arch backed at his adoring kisses, absentmindedly tugging at handcuffs by default. They were tacky things, but they did the job that was intended - making sure you couldn’t squirm your way out of every perfect thing that he had in store for you, and sometimes, what you had in store for him. But tonight, you both knew, it was all about you.
Kissing his way down your inner thigh now, smiling against your flushed skin, he said, “But your arrogance is becoming you, my dear.” He applied another kiss, further up your thigh now. “Did you really think you could spread your magnificent love to my brothers without consequence, hmm?” Another kiss, so close, yet so far. “Answer me, my love.”
He wanted you to answer him - but how could you even think straight when his lips were so close to where you desperately needed them to be? “A-Asmo,” you stuttered, trying to breathe through labored breathing and raw desire. “I-I would never, it’s… it’s only ever you , Asmo!”
Asmo knew that - without a second thought, you were always his . You would never cheat on him, or seek love from somebody else, let alone one of his brothers. But you’re the first person he’s ever been in love with in all of his years since his birth - how could he not be slightly territorial over your love? He couldn’t help but smile at your plea, however - it was always nice to be reminded who you gave your love to.
“Oh, Y/N…” Asmo pressed another soft kiss, again, so close to where you needed him. Asmo could see how wet you were without having officially touched you yet, and his patience was testing, but he had to endure. “Your love is overwhelming - I could never get enough of it.” Another. “I love you so much, my dear. Won’t you let me show you how much I love you?”
You nodded frantically, desperate for his touch. Whether it was his tongue licking against your clit or his cock railing you into the bed frame, you just wanted him to make you feel anything besides impatience. “Y-Yes, Asmo. Please, baby. Show me!”
Asmo smirked at that, noting the desperation in your pretty little voice. Leaning down again, Asmo applied one soft, generous kiss to your clit - watching your body shake at the fleeting sensation through hooded eyes. Just as quickly as he kissed you, he then removed himself from in between your legs, sitting up now and getting off of the bed. Through slightly hazy eyes, you watched as he made his way over to the bedside drawer’s bottom shelf, which you knew from experience held a collection of his favorite sex toys. What Asmo pulled out, however, made your eyes widen in both fear and excitement.
It was a vibrator - a small, pink, expensive-looking, remote controlled one, as Asmo had the remote control in his other hand.. It was new, too, because you had never seen this one before. Asmo smiled down at you as he pressed one knee down on the bed so that he could lean down and press a kiss to your forehead, pressing the tip of the vibrator between your breasts. “Do you trust me, my beautiful Y/N?” You nodded, muttering a quiet approval. Meanwhile, Asmo trailed the vibrator lower down your chest. “Good - I’m so glad. Let me show you how much I love you. I want you to feel everything you make me feel, and know that no other man or demon could give you my love.”
Asmo teased the tip of the vibrator against your clit, though preparations were hardly needed - you were already soaked from the teasing alone. With a small click, the vibrator started to life as he teased it at your entrance. You gasped at the sensation because, at the same time, Asmo kissed you long and hard on the lips. But The Avatar of Lust wasn’t quite done there - before you knew it, he had slowly shoved the remote control inside of your pussy.
You could hardly register Asmo climbing into bed with you with the vibrator jolting inside of your pussy at its highest setting - giving you absolutely no time to adjust to the foreign object inside of you. Asmo had adjusted himself onto your right side and held you in his arms, your left side half propped up against his right side. Asmo wanted to physically feel you chasing your orgasm - absolutely every second of it.
“Do you feel that, my darling?” Asmo whispered into your skin, placing a delicate kiss on it while the sound of every whimper and tangled moan that escaped your lips played like music to his ears. Meanwhile, your body shook uncontrollably. “Don’t you feel the intensity of my love? You can feel it all through your body, can’t you? Why would you seek that anywhere else, hmm?”
“Asmo,” you pleaded, your legs shaking like they could fall off at any second. Asmo was keeping the vibrator at the highest setting - this you knew as you could feel an impending orgasm close to being wrenched out of you. Asmo’s fingertips trailed over your sides, moving his kisses from your shoulder to ghosting over the shell of your ear.
“Do you feel that high, my love?” Holy shit, holy shit, holy shit. “That euphoric bliss you’re chasing is what you desire. It’s what defines me, my love - let it define you, too.” Fuck, fuck, fuck! “Let me define you, my darling - and me aloneI!”
Without warning, the dam breaks - and the orgasm was wrenched out of you like water being rung out of a wet shirt. Your back arched and your body shuddered at the euphoria, and an impossible to subdue scream escaping your lips followed. Your orgasm came quickly, but you had zero time to recover - because Asmo never turned the vibrator off.
“Oh, yes my love!” Asmo praised you, gripping your nervous sides with sharp fingernails and pressing his lips to your cheek. “That’s my girl! Let it all out for me, announce your deepest desires to the world!”
The feeling inside of you could hardly be put into words - you could feel the overstimulation in every single bone in your body, and you could hardly take any more. “A-Asmo, please… I… I can’t…It’s too much!”
“Fuck, darling! My beautiful Y/N - yes, you can!” Asmo encouraged you, arms snaking around your waist, slightly encouraging your movements as well. Even if he wasn’t the one mercilessly fucking you into the bedframe, he would surely help you fuck the plastic toy bringing you to your second orgasm. “Don’t disappoint me now, Y/N - show me your most beautiful and intimate desires, my dear. Show me everything !”
You were a goddamn mess in his arms - the spit pooling in your throat and drool dripping down your chin made it just barely possible to even breathe. Your brain shut down completely - all you could focus on was the grand intensity inside of your pussy as the vibrator fucked a second orgasm out of you, and a third, and a fourth, until the batteries finally gave what felt like an eternity later. Almost immediately, you were quick to pass out in Asmo’s arms, the world fading to black as the punishment for your arrogance came to a close.
