Word Count: 1.7k
“Baby,” your boyfriend's voice slurred, accompanied by a couple of suspicious thumps. You raised your gaze from your book, sliding out from under your blankets to investigate.
A great sigh left you as you opened your bedroom door to find your boyfriend slumped against the wall across from you.
Plastered.
“Mark,” you deadpanned, unsurprised.
“Hi, beautiful,” he drawled, his head lolling to the side. His big, glassy brown eyes watched you almost reverently. You were less than unimpressed. Shaking your head, you bit back your smile as you leaned against your door frame.
“You're drunk.”
“Yup,” He confirmed with a hiccup. “Didn't know that was possible. But—gosh, you're so pretty—But it is.”
“How did you even get in here?” you questioned, leaning out further into the hall. Your parents weren't home, thank God. You had the whole house to yourself tonight—or so you'd thought, when Mark said he was going out for Rex’s birthday. You'd expected him—at the earliest—tomorrow afternoon.
“Bathroom. Window. Tight squeeze,” he drawled, one hand lazily pointing over his shoulder.
You inhaled deeply through your nose before kicking off your door frame.
“Okay, let's get you cleaned up and ready for bed.”
That's how you found yourself bent over your bathroom sink counter, with Mark on his knees eating you out from behind like it was his last meal.
It was nearly two—you should've been asleep already, damn it. But Mark was nothing if not determined and—
“God, it feels so good,” you mewled, rolling your hips back against his face.
You gripped the counter until your knuckles turned white, swallowing your screams as you came. Mark hummed in satisfaction, making out with your sopping cunt as his thumb drilled your clit.
You were nearly sobbing when he finally slowed to a stop, the aftershocks causing your legs to tremble. You pressed your cheek against the cold countertop, focusing on steadying your breathing. Mark whispered praises over you, kissing the soft flesh of your ass and petting you with his fingertips. You sucked in a breath as his touch began to inch closer…And closer... And closer, until he was circling your back entrance.
“God, wanna fill this pretty ass up while I'm fucking you,” Mark finally whispered, his thumb ghosting over your puckered hole. You tensed, heart stilling. You surprisingly didn't hate the feeling. You actually… kind of loved it.
But he was too out of it—still plastered—to realize what he was saying…Or, confessing. Mark prided himself on being a gentleman and, to be honest? He was a little shy. You knew he'd never have divulged this information if he weren't drunk.
You glanced over your shoulder, chest still heaving.
“Yeah?” you questioned softly. Mark groaned, nearly lost in thought as he licked his lips. His eyes were locked in, flickering between your pussy and your ass.
“Yes, please lemme plug you while I'm fucking you, baby,” He nearly whimpered, voice raw. You suppressed a shiver, your core tingling. A mischievous thought popped into your head. With a sigh, you straightened and turned to him.
“Baby, it's late,” you frowned. Mark’s eyes fluttered up to yours, disappointment prominent in his gaze. But, eventually, he nodded.
“Yeah, yeah, another time maybe.”
Two Weeks Later
Mark’s chest rumbled as he ran a palm down your spine, pressing your facefurther into the pillow and your ass higher up.
He was fresh out of a fight, high on adrenaline, and itching to spend it on you. He’d barely made it in the door before grabbing you, stripping you, and throwing you on your bed.
You were now one orgasm in, sighing as he spread you open. You felt the tip of his cock nudge against your entrance.
“Wait,” you gasped, hand reaching back. Mark stilled immediately.
“What? Is something wrong?”
You smiled softly, turning onto your back.
“I wanna try something.”
Mark raised an eyebrow, slick chest glistening in the mood light flickering in. You tried to hide your smile, glancing excitedly toward your bedside table. Mark followed your eyes before glancing back at you.
“Open it,” you whispered, full of anticipation. Mark scooted backward, leaning over to open the drawer, only to find…
Mark’s eyes widened to the size of saucers, lips parting in surprise.
“You… what?”
You smiled as a faint blush covered his cheeks, falling down his chest.
“Baby, I—um… Gosh, I—” he stuttered, one hand rubbing the back of his neck. You grinned at his shyness. “I didn't know that you…knew about that.”
“You were the one who told me,” you smirked, leaning back on your elbows. Mark seemed to blush further.
“God, I thought that was a dream,” He whispered, eyes downward. A moment passed, him seemingly lost in thought. You let him decide, watching in silence. Finally, he glanced up at you, eyes dark and jaw set.
“You’re okay with this?” he asked softly. You released a deep breath, nodding slowly.
“I've never done anything like this, and I'm nervous, but I'm okay with it.”
Mark swallowed visibly, trying to suppress the excitement that lit up his face. He reached into the box, pulling out a small butt plug. It was silver, with a blue heart on the end.
“I’ll be gentle, baby, I promise,” He assured, voice shaking. Mark set the plug down beside him, guiding you as you flipped back over. He leaned down, delivering slow, hot kisses to your spine.
You shivered as he reached your ass, groaning quietly as he spread you.
And then licked, tentatively.
You jolted, eyes flying open as pleasure zipped through you. You gasped, cheek pressed against your pillow, swallowing a brazen moan as Mark repeated the action.
“Don’t,” He ordered, teeth pressed into your skin. “I want to hear you.”
You whimpered, relaxing into him as he continued lapping at you. And, God, it felt incredible.
Your thighs trembled, knees threatening to buckle as his tongue pressed into your backside.
“Holy shit,” you whimpered, Mark, humming in satisfaction.
“‘M gonna start stretching you out, okay, baby?” Mark murmured, squeezing the globes of your ass.
You could only nod, mouth gaping in euphoria.
Mark leaned back a bit, before spitting directly on your asshole and then—
You sucked in a breath as you felt his pointer finger press against you, before slowly pushing in.
“F-fuck,” You hissed, trying not to buck against the slight burning intrusion. It was different and intense, but it wasn't bad. No, it was just…
“It’s a lot, baby, I know,” Mark comforted, his other hand running down your spine softly. You mewledas he pushed in further, fingers digging into the sheets beside your head.
Mark worked you faithfully, diligently, and lovingly, pumping and curling and drawing raw sounds from you. Ten minutes passed before he added a second finger.
Five minutes passed after that before you were coming, guttural and broken, you dripping pussy clenching on nothing.
“Such a good girl,” Mark purred. He was in awe of you. Hungry and desperate. “You look so beautiful with my fingers in your ass.”
You panted as he finally slowed, pulling out and sitting up on his knees. He massaged you lightly as he searched for the plug.
“You ready, sweet girl?” He asked, leaning down to brush kisses along your face.
“Mhmm,” you hummed, nodding with your eyes closed. Mark chuckled before leaning back. He spread you once more with his hands, cursing as his eyes landed on your cunt and ass. After a moment, he spat once more.
And then you felt it.
Cold and heavy and big, pressed right against your back entrance.
“Ahh—” you gasped, hips jerking. Mark shushed you comfortingly, his other hand massaging your hip. He swirled the metal object around your hole before pushing in. And in. And in.
And even though it couldn’t have been longer than two inches, it felt enormous. Overwhelming and intense, and you felt like you could barely breathe. But past the burn and the stretch, past the pressure and initial shock, there was pleasure. You arch your back when it finally slid in, a whine falling from your lips.
“So perfect,” you heard Mark whisper in wonder, his hand dipping in between your thighs. You cried out as his fingers found your clit, administering slow, tender circles. He kept you there, coaxing you into relaxation until you were dripping down your thighs and drooling on the pillowcase. And finally, he lined himself up behind you.
He was incredibly—painfully—hard against you, nudging into your folds.
“Say the word, and I’ll stop,” he murmured, his thick tip pressing into the entrance of your pussy. You braced yourself, nodding. And he pushed in.
An inch by thick, glorious inch at a time, he sank into you. Unholy, filthy noises fell from both of your mouths, mixing and harmonizing with each other.
You were so, so full. So stretched around your lover—stars dancing behind your eyelids. It was otherworldly, the pleasure consuming you as he pushed you further.
“That’s it, that’s my girl,” Mark growled, trembling as he tried to restrain himself. “Take it all, baby.”
You did. And you loved it. You cried out as Mark bottomed out, tears brimming in your eyes.
“Jesus Christ, ahh,” He groaned, his head thrown back. Broken whimpers fell from his lips like a waterfall, soaking into your clammy skin below. “Feels so fucking good.”
He pulled out, hands twitching on your hips, and thrust back in. Slowly once. Slowly again. And then,
“Mmm, fuck, I—God, I can’t, I’m sorry,” He choked out before he began to pound in and out of you. Deep, powerful, measured strokes, forcing your body deeper into the mattress below you. You sobbed in pleasure, gasping as he planted a palm on your back and pushed your ass further up.
He raised a leg up, resting on one foot and one knee, and you shrieked at the new angle. Over and over and over, pumping in and out with fury.
Until you were coming, unfurling around him and basking in the ecstasy. You called out his name like a mantra, begging him. More, more, more.
Three orgasms later, and Mark finally stilled, sweaty and shaking as he spilled into your ruined pussy. He collapsed atop of you, immediately moving to cradle you in his arms. You both panted like dogs, bodies spent and sated.
Mark huffed a laugh, snuggling into your neck and kissing the flesh there.
“I think I’ve found my new favorite toy.”
