Yours Only

As Ariana made her way back to Cami, her mind was reeling from the intense encounter with Mateo. The weight of the diamond collar seemed to pulse against her skin, a constant reminder of their forbidden connection. She took a deep breath, trying to compose herself before facing her best friend.

Cami was in the kitchen, directing the staff with the efficiency of someone born into wealth and privilege. She looked up as Ariana entered, her eyes sparkling with excitement. "There you are! I was starting to think you'd gotten lost. Come on, I want to show you what I got in my stocking!"

She grabbed Ariana's hand, tugging her towards the Christmas tree. As they walked, Ariana couldn't help but feel a thrill run through her at the secret she now shared with Mateo. It was like a dangerous game, hiding in plain sight.

As the day wore on, Ariana found it increasingly difficult to focus on the festive activities. Her thoughts kept drifting back to Mateo's heated words and the way his hands had possessed her body. She caught him watching her throughout the meal, his eyes smoldering with barely restrained desire.

Later, as the family gathered to open presents, Ariana struggled to feign enthusiasm. She watched as Cami tore into her gifts, her laughter ringing out in the grand living room. All the while, Ariana could feel Mateo's presence beside her, his thigh brushing against hers under the pretense of reaching for another present.

When it came time for Ariana to open her gifts, she was surprised to find an elegant box among the pile. Inside was a stunning emerald pendant, its color a perfect match for her eyes. Cami squealed with delight, clapping her hands.

As the long, torturous day finally drew to a close, Ariana found herself alone in her room, the emerald pendant heavy around her neck. She stared at her reflection in the mirror, seeing the flush of arousal still coloring her cheeks, the way her lips were slightly swollen from Mateo's kisses. The diamond collar glinted in the low light, a silent promise of what was to come.

A soft knock at the door startled her. Before she could respond, Mateo slipped inside, closing and locking the door behind him. He leaned against it, his eyes raking over her form hungrily. "Did you miss me, mi amor?" he purred, his accent thicker than usual. "I've been counting the minutes until I could have you alone again."

He stalked towards her, shedding his sweater as he went.

Ariana's breath caught in her throat as Mateo advanced on her, his chiseled torso on full display. The air between them crackled with sexual tension, the events of the day culminating in this charged moment. She backed up until her legs hit the edge of the bed, nowhere left to retreat.

"I thought about you all day," Mateo growled, backing her onto the mattress. "Every smile you gave Cami, every laugh... I wanted to march over there and claim your mouth in front of everyone." His hands gripped her hips possessively as he loomed over her.

One hand slid up her side to cup her breast, thumbing her nipple through the thin fabric of her dress. "You're mine, Ariana. Your pleasure, your pain, your very soul - it all belongs to me now."

Ariana's body trembled under Mateo's dominant touch, her nipples hardening into aching peaks beneath the emerald pendant. She gazed up at him with hooded eyes, her lips parted invitingly. "Yes, I'm yours," she breathed, arching into his caress. "Only yours."

In a swift motion, Mateo pushed her dress up around her thighs, exposing her lacy panties. He hooked his thumbs in the delicate fabric and ripped them away, baring her completely. "Fuck, you're soaked already," he groaned, running a finger through her slick folds. "So responsive for me."

He unzipped his pants, freeing his thick, hard cock. Ariana licked her lips at the sight, remembering how he had stretched and filled her so perfectly the night before.

Mateo positioned himself between Ariana's spread thighs, the blunt head of his cock nudging insistently at her entrance. He leaned down to capture her lips in a searing kiss, swallowing her moans as he slowly pushed forward, sheathing himself inside her tight heat inch by delicious inch.

"Ahh, fuck yes," he grunted against her mouth, savoring the exquisite sensation of her walls fluttering around him. "You feel even better than I remembered, mi amor. Like you were made just for me."

Once fully seated, he began to move, setting a deep, powerful rhythm that had the bed frame creaking in protest. One hand tangled in her hair, tugging her head back to expose the column of her throat. He latched onto the sensitive skin, sucking and biting, determined to mark her as his own.

Ariana cried out in ecstasy as Mateo pounded into her, each thrust hitting that perfect spot deep inside that made stars explode behind her eyelids. Her nails raked down his back, leaving red welts in their wake as she clung to him desperately.

"Yes, yes, just like that!" she keened, wrapping her legs around his waist to pull him impossibly deeper. The obscene sound of skin slapping against skin filled the room, mixing with their labored breathing and wanton moans.

Mateo angled his hips, driving into her g-spot with laser precision. "That's it, baby girl. Take my cock like the greedy little slut you are," he snarled, punctuating each word with a sharp snap of his hips. "This cunt belongs to me now. I'm going to ruin you for anyone else."

Ariana could only whimper and writhe beneath Mateo's relentless assault, her body completely at his mercy. Pleasure coiled tighter and tighter in her core, threatening to snap at any moment. Tears of overwhelming sensation leaked from the corners of her eyes as she teetered on the razor's edge of release.

"Not yet," Mateo commanded, sensing her impending orgasm. He slowed his movements to a torturous crawl, keeping her suspended in agony. "Not until I say you can come, understand?"

Ariana nodded frantically, too far gone to form words. She squeezed her eyes shut, trying desperately to stave off the tsunami building within her. Mateo smirked cruelly, amused by her struggle.

"That's my good girl," he praised, rewarding her obedience with a few fast, brutal thrusts. "Such a perfect little toy for Daddy to play with."

Mateo increased his pace once more, pounding into Ariana with wild abandon. The bed shook violently, the headboard slamming against the wall in a staccato rhythm. Sweat dripped down his sculpted torso as he chased his own release, his balls tightening with impending eruption.

"Ariana..." he choked out, his voice strained with pleasure. "Fuck, I'm gonna fill this sweet cunt with my cum. You want that, don't you? Want Daddy to breed you like the desperate little slut you are?"

Ariana could only sob in response, her body trembling uncontrollably as the dam finally burst. Her orgasm crashed over her in wave after wave of pure bliss, her inner muscles clamping down around Mateo's pistoning cock like a vice. "YES!" she screamed, her voice hoarse from exertion. "Fill me up, please!"

With a roar of triumph, Mateo slammed home one final time, burying himself to the hilt as his climax overtook him. Hot ropes of cum painted Ariana's spasming walls, marking her irrevocably as his. He continued to grind against her, drawing out both their pleasure until they collapsed together in a sweaty heap.

"My god, woman," Mateo panted, pressing tender kisses along her jawline. "You undo me. I've never felt anything like that before." He rolled to the side, gathering her limp form against his chest.

Ariana hummed contentedly, tracing idle patterns on his abdomen. "Mmm, I could get used to this," she murmured sleepily. "Maybe we should make this a Christmas tradition..."

Mateo chuckled, squeezing her tighter. "Careful what you wish for, mi amor."
