I gulp, pressing my thighs together as tightly as possible.

When I don't immediately obey, frozen by how surreal this feels, he slams his hand on the desk with a growl. "That's one. Now, take off your pants and panties."

I leap to my feet, my insides fluttering with pleasure, his commanding tone melting me. Standing there in Adam's office in just my bra and shirt, I feel ridiculous—exposed.

Adam just stares at me for a moment, then pulls me close, one hand gently caressing my ass while his other expertly unhooks my bra. He kisses my forehead before whispering in my ear, "You're not to wear these anymore."

Another shiver runs through me at the decree.

"Do you understand?"

"Y-yes," I stammer, trying to concentrate on his words as his hand slides down my ass and a finger pushes against the rim of my ass before finding its way between my lips. I groan as two fingers thrust in and out of my pussy, causing me to grind my hips against his cock.

"That's two," Adam says, thrusting faster. "Yes, what?" He pulls away abruptly, removing his fingers from inside me, his brows furrowing in displeasure.

Shit.

Not even a few minutes in, and I'm already breaking the rules. This is going to be harder than I thought. "Y-yes, Mr. Marsters."

A moan slips from Adamas he presses his bulging pants against me for a moment. Then, with a wicked smile, he pulls away, rummaging through one of the bags before retrieving something I can't quite see.

"Good girl," he says, fastening something around my neck. He holds up the mirror he gave me, and I see a collar with a tag gleaming with the words, 'Mr. Marsters' Good Girl.' I start to pull at it, but he swats my hand away. "You're my property, and I want everyone to know it. Understand?"

I bite my bottom lip and can only manage a nod as I suppress a moan.

"That's three," Adam says in a low, menacing tone as he begins to undo his tie. I wonder what that means but can't think too much about it because before long, he turns me around, binding my hands behind my back with the tie. "Bend over," he growls.

I obey, bending over, and he smacks my ass hard.

"I meant on your knees," he corrects with a hint of menace.

"How was I supposed to know that?" I ask, glancing back at him, wiggling my hips to ease the searing pain radiating from my ass.

Smack! The next one lands even harder, sending an intense throbbing through my clit.

"No backtalk," he orders, his eyes dark and delicious. "Now, turn around and get on your knees." Before I can comply fully, his fingers plunge into me without warning. This isn't like earlier during our conversation about the contract. No, these fingers are relentless monsters ready to ravage every bit of my pussy. He thrusts them in and out of me in furious succession.

"Y-y-yes," I say, and he thrusts in me the hardest yet, reminding me of my mistake. "M-Mr. Maarrsters."

I collapse onto the carpet, trying to remain balanced, but the relentless onslaught of his fingers mauling my pussy overwhelms me. My head falls to the floor as I moan, his fingers dragging my body back and forth with every thrust.

"Good girl. Now, stay like that," he says, withdrawing his fingers from me. I whimper, suddenly feeling empty and desperate for him to fill me again. I glance back at him as he returns to the bags, but he catches my disobedience and scowls. "That's four. Face forward."

I quickly turn back, trying to rub my nipples against the carpet to continue my journey to nirvana, but before I can find it, Adam returns and delivers a sharp slap to my ass. I turn back around and try to rub my nipples against the carpet, so I can continue being pushed to nirvana, but Adam returns and slaps my ass.

"Did I give you permission to pleasure yourself?"

"N-no, Mr. Marsters."

"Now, let's begin obedience training."

Before I can ask what he means, I feel the cool squirt of gel between my cheeks. His finger presses against my rim, and tears spring to my eyes as Adam's thick finger wiggles its way inside my ass. It's only one, like other night, but it's deeper, stretching me even more. I moan, instinctively widening my stance and pushing back, but he halts me.

"I'm in control," he reminds me, holding me still. "That's why you need a two-weeklong obedience intensive. You're a little untrained pup."

I want to object to being called an "untrained pup" and ask what an obedience intensive entails, but I can't form words. All my brain cells are focused on the foreign object waging war on my growingly tender, throbbing hole.

The room is filled with the quiet rhythm of his finger sliding in and out of me. My soft moans and mewls echo against the walls, the only sound until Adam pushes a second finger inside, and my body skyrockets off the floor.

"Aaaahhh! Adam!" I cry, glancing back at him. He smirks and swirls a finger in the air, motioning for me to turn back around. I do, whimpering, as his two fingers stretch me beyond anything I've felt before. My legs thrash, my ass shaking in protest as his fingers spread me wider. A guttural groan escapes me.

"Shhh, you wouldn't want Eliza to find you like this," he whispers against my cheek, licking away a stray tear as he picks up the pace, thrusting faster. "Would you? She does have a key."

"N-n-no, Mr. Mr. Mar-Mars-ters," I manage to stammer through my whines. I bite my lip hard, trying to suppress my noises, but when he slides a third finger inside, my body stiffens. He thrusts furiously, and I go limp, drooling in ecstasy as his meaty digits push me back and forth, my head dragging against the carpet.

My thighs are slick with my own juices, and I pant heavily like the animal Adam said I was as he dominates my ass. My muscles spasm, and I clench tightly around his fingers, but he keeps thrusting, pushing me through the waves of my orgasm. Exhausted, I collapse onto the floor, panting, Adam's newly tamed pet.

"I expect you to behave like a good girl from now on," he murmurs, lifting me up by the collar and kissing me tenderly between my pants.

My head just lolls toward the floor. I'm too drained to speak, and the only reason I'm upright is the firm grip Adam has on my collar. Understanding this, he gently lays me back onto the drool-stained carpet.

He rubs my sore ass before standing up. I hear the rustling of bags and know he's at his desk again, but I've learned not to look at what he's doing. Moments later, he lifts me off the floor and splays me in his office chair. He peppers me with kisses as he unbuttons my shirt. Each time his lips brush my carpet-burned cheek, I wince, but the strange pleasure from the pain excites me. He pulls a pair of scissors from his desk and carefully snips the straps of my bra.

"You won't be needing this anymore," he says with a sly smile. From one of the bags, he pulls a small, oval-shaped object. He spreads my thighs, rubbing it in my slick juices, teasing my clit until a moan leaves my parted lips. Then, he slides it down past my folds, pressing it against my rim.

I try to clench, but my ass is still too loose from his earlier finger raid, and the object slides inside, fitting snugly. I groan, feeling even fuller than when his fingers were inside me. He smiles, kissing me softly before pressing a button and turning a dial on a remote.

My eyes bulge, and my body arches off the chair as I squeal from the intense buzzing emanating from my ass. Adam laughs, pulling me into him to muffle my screams as I thrash in the chair, overwhelmed by the massive vibrations. Another orgasm crashes through me, and I whimper when the buzzing stops. Panting, I collapse into Adam's crotch, new tears pooling in my eyes. He strokes my hair gently, kissing the top of my head before laying me back in the chair.

I swallow hard, watching him pull a large wooden paddle from one of the bags.

"Now that your introduction is complete, it's time for your punishment for breaking the rules," Adam announces, a beastly glint in his eyes. "Five smacks for every time you forgot to call me Mr. Marsters."

"What?! Adam—"

"That's five," he says with a chilling calmness, stroking the paddle while his eyes pierce through me. "Do you want it to be more?"

"No, Mr. Marsters," I quickly stammer, shrinking further into the chair.

"That's a good girl," he praises, flipping me over so that my knees are on the floor, and my upper body is draped across the seat. I hear the soft click of a button, bracing myself for the vibrator to roar back to life, but instead, it hums softly with a gentle, teasing pulse. My hips wiggle as Adam's hand caresses my ass. "Make sure you count each hit, or I'll be forced to add more," he warns, his voice low and commanding. "Make sure to say each paddling number, or we'll have to add more."

"Yes, Mr. Ma—"

Whack! The sudden, powerful strike of the paddle sends me crashing forward into the seat, crying.

"You forgot to count," Adam coos. "Looks like this is going to take longer than I thought. Let's start over."

Whack!

"One!" I cry into the seat.

Whack!

"Two!"

"Good girl," he murmurs, a note of approval in his voice.

The paddling continues, and soon, I'm responding automatically, my voice growing softer with each smack. By the time Adam finishes, I'm wiped—he doesn't stop until he's delivered thirty-five strokes. He claimed some of my responses had been too faint for him to hear, and he made sure I paid for them. When he finally unties my hands, they plummet limply to my sides, as exhausted as the rest of my body.

He scoops me up into his muscular arms, cradling me gently.

"You did so well," he whispers, nuzzling his face against my sweaty cheek. "Let's get you to bed so you can rest."

"V-vibrator," I mumble, unable to get my voice above a whisper.

He leans in closer, and I force the word out again, reminding him the vibrator is still inside me, buzzing softly. Adam chuckles, a wicked grin on his face.

"That stays where it is," he says, his voice dripping with satisfaction. "And it stays on... until morning."

I groan at the thought of sleeping with the vibrator still buzzing inside me, but I don't have the strength to argue. Instead, I curl up against his strong chest as he carries me down the hallway. I don't even care that I'm barely dressed as he carries me—my mind is too foggy, too focused on the sensations coursing through my body.

I'm briefly confused when he passes my bedroom and goes to his own room.

"My favorite pets sleep with the master," he says as he lowers me onto his bed.

I wince when my sore ass meets the cool sheets, and Adam, noticing, flips me onto my stomach before kissing me goodnight and pulling the covers over me.

I watch him undress and slip in beside me, his hard cock pressing against my thigh. Surprisingly, despite the low hum inside me, I feel sleep pulling at me. As I drift off, two thoughts flash through my mind.

What have I gotten myself into? And what delicious adventures will tomorrow bring?
