Uncle's Wedding Gift

Summary:

... "As your best man, I guess it's my job, isn't it, nephew? I'm the one charged with making sure today becomes one of the most unforgettable days of your life, right?"

Derek nodded, affirming, "Yes."

Peter continued, "Alright, don't get startled—just hear me out and keep an open mind. You recall that time I used to frequent that Alpha club before I met Chris, right? Well, I danced with a lot of people there, but there's one guy I encountered who left a lasting impression on me if you know what I mean."

Peter winked and swung open the door, revealing a tall, imposing black man who entered the room. He appeared to be between 25 and 30 years old, with a commanding presence at around 6'3" and weighing roughly 200 pounds. "Allow me to introduce Stiles," Peter announced with a grin. "Consider him my special wedding gift to you."

Work Text:

The long-anticipated day had finally arrived. Theo and his fiancé, Derek, had been together for a full two years before getting engaged, and now they had been in engaged bliss for an entire year. Derek, at 25, was an exceptionally handsome omega with striking green eyes, luscious brunette hair, and the kind of physique typically associated with an alpha. Standing at an impressive 6'0" with a robust and muscular build, he was quite the sight to behold.

Throughout their three years as a couple, Theo and Derek had chosen to keep their intimate moments somewhat reserved, having had limited sexual experiences. This decision was largely influenced by Derek's desire to save the full extent of their physical connection after the wedding, ensuring that it would be even more meaningful. However, they did enjoy some intimate activities such as fingering and oral sex, which helped them build anticipation for their wedding night. Derek believed that by holding off on certain experiences, the moment they finally came together in marital bliss would be all the more special, their longing intensifying the encounter.

The day before the wedding, Theo hadn't crossed paths with Derek, which only intensified his longing for his soon-to-be husband's touch. Desperate to see him, Theo hatched a plan to arrive at the church earlier than planned, hoping for a sneak peek of Derek as he prepared for the ceremony. Concealing himself in the dressing room, the beta watched eagerly as Derek entered with his uncle Peter, who happened to be both an omega and Derek's best man.

Dressed casually in tight yoga pants and a t-shirt, Derek's alluring physique was on full display. His perfectly shaped bubble butt and muscular legs were emphasized by the snug fit of his attire, causing Theo's average-sized cock to throb with anticipation. Derek's beauty was undeniable, and as he swiftly stripped off his clothing, revealing his entire nude form, Theo was almost overwhelmed with desire.

Peter assisted Derek in donning a corset and white stockings, a customary choice for omegas in their society who often embraced traditionally feminine clothing. It was not unusual for strong, hairy omega men like Derek to be dressed in such a way. Derek then slipped into a pair of sexy white panties and expertly fastened his garter.

Just as the preparations seemed complete, a sudden knock on the door interrupted the moment. Derek paused, curiosity piqued, as he speculated about who could be visiting them at such a time.

Peter smirked and said, "As your best man, I guess it's my job, isn't it, nephew? I'm the one charged with making sure today becomes one of the most unforgettable days of your life, right?"

Derek nodded, affirming, "Yes."

Peter continued, "Alright, don't get startled—just hear me out and keep an open mind. You recall that time I used to frequent that Alpha club before I met Chris, right? Well, I danced with a lot of people there, but there's one guy I encountered who left a lasting impression on me if you know what I mean."

Peter winked and swung open the door, revealing a tall, imposing black man who entered the room. He appeared to be between 25 and 30 years old, with a commanding presence at around 6'3" and weighing roughly 200 pounds. "Allow me to introduce Stiles," Peter announced with a grin. "Consider him my special wedding gift to you."

Startled, Derek instinctively reached for his clothes, clutching them tightly against his bare skin in an attempt to cover himself. "Peter, have you lost your mind?" he exclaimed with a mix of shock and frustration. "I'm getting married today! You know I've always been faithful to Theo and would never cheat on him. Please, get him out of here immediately."

Peter, unfazed, replied, "I know you've been loyal, and I'm aware you've never experienced what it's like to be with a true Alpha. That beta of yours, with his modest size, can't compare. I couldn't think of a better gift than letting you have an encounter with a large black Alpha cock. Just once, and it'll be our little secret." As he spoke, Peter smoothly removed Stiles's shirt, revealing a well-defined chest and sculpted abs. He then pulled down Stiles's shorts, unveiling an enormous, flaccid black cock.

Theo, who was hidden away, was utterly taken aback. It was the largest member he had ever laid eyes on, even in its unaroused state. For a moment, he contemplated bursting out of his hiding spot to put an end to this madness. However, noticing Derek's clear discomfort and resistance, he decided to remain hidden, unwilling to reveal his secret vantage point.

Derek stood there, seemingly mesmerized by the sheer size of Stiles's manhood.

Sensing an opportunity, Peter wrapped his white hand around the massive organ and began to stroke it gently. "I bet Theo's isn't this big, is it?" he taunted, as the cock started to swell and grow in his grasp.

Derek, somewhat reluctantly, admitted, "No, not even close."

Theo's attempts to halt the scenery before his eyes faltered as Derek, his beautiful fiancé, spoke up, his voice firm and unwavering. "No, I can't cheat on Theo."

Stiles, however, was unyielding. "I don't care which one of you sucks this big dick, but I'm not leaving until one of you empties my balls."

Peter encouraged, the reluctant fiance "Come on, nephew, just give it a shot; no one will find out. It feels amazing, and trust me, size is significant. Don’t deny yourself this pleasure." With that, Peter knelt down and began to take Stiles's impressive member into his mouth. Only the large tip of Stiles's length was penetrating Peter's lips, filling his mouth entirely. Stiles placed a hand on Peter's head as Derek’s uncle eagerly began to work on him. Stiles was semi-erect, measuring about 10 inches in length and quite thick—so much so that Peter's middle finger couldn't even reach his thumb. Peter looked utterly captivating as he devoted himself to Stiles's impressive size.

Now fully aroused and reaching about 11 inches, Stiles removed himself from Peter's mouth and approached Theo's future husband. Derek stood there, a mixture of shock and intrigue on his face, as Stiles guided Derek's hand to his massive member. Instinctively, Derek began to stroke Stiles, slowly becoming entranced by the moment. Before long, Derek found himself kneeling, unable to resist any longer as he opened his mouth, allowing Stiles's impressive length to stretch his lips. Theo watched in disbelief, taken aback by the unfolding scene before him.

Stiles let out a low growl, his alpha red eyes blazing with intensity. "That's right, take that big black dick like the little slut you are. I can only imagine how tight that little white omega boypussy must be." 

In a surprising shift, Derek stood up with a newfound confidence and removed his panties. "Why don’t you find out for yourself, big boy?" he challenged, striding over to the couch. He reclined back, spreading his legs invitingly. Theo watched in a mix of awe and helplessness as his stunning fiancé, with his tight little virgin pussy glistening, prepared to be claimed by the overwhelming presence of Stiles's massive black cock. The scene was charged with energy, and Theo felt a wave of frustration wash over him; he was powerless to stop it.

Overwhelmed by the betrayal of his fiancé, Theo found himself unexpectedly aroused, his pants stained with a massive load of cum, reminiscent of the submissive role he never thought he’d take, a cuck. Stiles approached, his large cock swinging confidently in front of him. As he settled between Derek's sturdy, hairy thighs, Derek reached out, gripping Stiles's impressive length.

With a mix of eagerness and innocence, Derek began to rub the broad head of Stiles's cock against his own tight, virginal pussy, slicking it with the juices that overflowed from him. Stiles leaned in, capturing Derek's lips in a heated kiss while Derek continued to maneuver Stiles's impressive shaft against his entrance. 

Finally, Derek positioned the massive cock at his entrance, and Stiles began to push in slowly, causing Derek to break their kiss with a gasp as he felt the pleasurable stretch. Theo watched, captivated and pained, as a mix of emotions flickered across Derek's face; a hint of discomfort surfaced as Stiles worked his way inside, causing Derek's eyes to shift between a deep omega blue and a striking green, reflecting the intensity of the moment as he was filled.

"I always knew you would have a snug little pussy, just like your uncle" Stiles growled, a playful smirk dancing on his lips.

Derek gasped, overwhelmed by the sensation. "Oh my god, your cock is fucking huge! It's really stretching me!" he mewled, lost in a whirlwind of pleasure and desire.

"Do you want me to stop?" Stiles inquired, a teasing grin spreading across his face, fully aware of what Derek would say next.

"Absolutely not! Don’t you dare stop; it feels so incredibly good!" Derek moaned, his voice filled with urgency and longing, resembling a creature in heat yearning for more. His body writhed in anticipation, craving the intense sensations that coursed through him.

Stiles was already deep into Theo’s fiancée when he heard Derek let out a moan, his body beginning to tremble. "I’m about to cum on your massive dick," Derek gasped breathlessly. 

With a powerful thrust, Stiles pushed in a few more inches, a smirk crossing his face as he taunted, "That’s how you know you’re getting a good big black dick wrecking your pussy, you little white slut." 

Derek's reaction was immediate; he screamed as the sudden force of penetration sent waves of intense sensation coursing through him. "It’s so big and black!!" he cried out, caught between pleasure and the overwhelming intensity of the moment.

Stiles growled, a fierce intensity in his voice, "Exactly, Don't forget what’s wrecking you, you stupid cheating bitch." 

For a moment, Stiles maintained his deep connection with Derek, savoring the sensation before beginning to pull back. He then slid back in slowly, causing Derek to squirm with a mix of pleasure and discomfort as Stiles pushed deeper into him. The overwhelming sensations triggered a second wave of ecstasy for Derek, leading him to climax once more as Stiles started to withdraw. 

With renewed vigor, Stiles thrust back in, his movements becoming faster and more assertive as he navigated the tight confines of Derek's tight virginal pussy. The rhythmic pumping sent waves of pleasure coursing through Derek, who found himself moaning in ways that Theo had never witnessed before. Despite their previous encounters, where Derek would often need to stimulate himself after being touched by Theo, this time was different. Stiles, with his impressive size, was able to coax multiple orgasms from Derek simply by stretching him, leaving a lasting impression on both him and Theo.

The room resonated with the rhythmic sounds of their bodies meeting as Stiles fully engaged with Theo's boyfriend, Derek in the animalistic sex they were having. Theo couldn't help but notice how much Derek's pussy had adjusted; he could see the way Derek's wet pussy accommodated Stiles as he withdrew, only to thrust back in. Stiles's impressive testicles made a pronounced impact against Derek's rounded backside, emphasizing the depth of their connection as he sank eleven inches deep into the omega.

Derek's moans filled the air, begging for more, "Please, don't stop! I want your big cock in me always!" The intensity of their passionate encounter continued unabated for fifteen minutes, until Stiles finally pulled out, leaving Derek's pussy, wrecked gaping, and empty, a testament to the pleasure they had shared and changed position. 

Without hesitation, Derek climbed onto Stiles as the Alpha had sat on the couch, and the Omega eagerly sought to reclaim that sensation as he guided Stiles's impressive member back into him. It was clear that Derek's body had become well accustomed to Stiles's size, easily accepting him once more. As Derek began to rock his hips, he reveled in the feeling of being filled, riding Stiles’s cock with fervor. 

After some time, Derek turned around, allowing his voluptuous, hairy backside to land against Stiles. He spread his legs wide, inadvertently directing his actions toward Theo, as he impaled himself on Stiles's massive length. The sight was undeniably captivating, with Derek's juices glistening as they dripped from Stiles's large testicles. 

Theo watched as Derek bounced on Stiles's invading cock, his body stretched and eager. Suddenly, Stiles took control, gripping Derek's hips and pulling him down, holding him tightly against his powerful frame. The dynamic in the room shifted as their desire intensified, creating a scene filled with raw passion and unrestrained pleasure.

"I almost cummed in that pussy.” Stiles growled maintaining the contact of his red eyes with Derek’s blue ones ” You love this big black dick don't you?"

"I love your huge black cock." Derek purred meeting Stiles’ gaze while impaling himself like the cheating whore he now was. "Go ahead and cum in your pussy. Give me your big black cock seed. Fill my little white womb full of your cum."

"You want my black baby in that white belly, don't you? Stiles growled, smiling sadistically

"Yes!! Please give it to me." Derek mewled.

Without needing any encouragement, Stiles swiftly lifted Derek and positioned him on his hands and knees. Taking his place behind Derek, Stiles wasted no time as he plunged his impressive member deep into the omega's welcoming body. With a firm grip on Derek's hips, Stiles began to thrust more vigorously, driving deeper with each powerful movement.

Theo could hear the unmistakable sound of Derek's slickness, the wetness of his body evident as Stiles continued to penetrate him. The rhythmic slapping of Stiles's sizable testicles against Derek's sensitive clit added to the symphony of their passionate encounter, filling the room with an intoxicating blend of sounds that spoke to the intensity of their connection. Each thrust resonated with raw desire, showcasing the primal energy between them as they lost themselves in the moment.

"I'm feeling it swell inside me. Please give me that baby. You deserve to be the father of my first child. Fill me up! Fill your omega’s pussy!" Derek moaned, his voice a blend of desperation and longing.

Stiles responded with primal grunts, driving his impressive size deep into Derek, who was soon to be Theo’s husband. Gripping Derek's hips firmly, Stiles let go, unleashing his potent essence into Derek's receptive form.

"Yes, fill me completely! Fill your omega with your seed. I can feel it, all that warmth fertilizing me. Oh wow, that’s so much! Just let it all out inside my fertile pussy," Derek exclaimed, his voice rising with each wave of pleasure as he experienced the fullness of Stiles's seed, feeling the promise of new life growing within him. The intensity of the moment left them both breathless, caught in a whirlwind of passion and desire.

Stiles poured himself into Derek for what felt like an eternity, his release lingering inside him for at least a minute. As the waves of pleasure subsided, Derek propped himself up, still enveloped by the warmth of Stiles’s dick, and leaned in to kiss him deeply. "That was the first time I've ever experienced something like that, and it was absolutely incredible. If you ever find yourself wanting some more, just say the word. You can have me anytime," Derek whispered with a playful grin as he felt Stiles’s cum swimming deep inside his pussy and beyond.

With a soft sigh, Stiles withdrew, leaving Derek reclining on the floor, a glistening strand of cum trailing from Stiles's impressive dick to Derek's inviting and obliterated pussy. After gathering his clothes, Stiles quickly dressed and made his exit, leaving Derek in a blissful haze.

Just then, Peter walked in, a knowing smirk on his face as he helped Derek to his feet. "So, how did you enjoy that little wedding gift?" he teased, clearly amused by the scene that had just unfolded. Derek couldn't help but smile, still reeling from the intensity of the moment he had shared with the man that just left.

Derek felt a rush of satisfaction as he recounted his recent encounter, clearly relishing the experience. "I have to admit, I doubt I'll find anything else as pleasurable as that. His cock was so big and impressive, and it really does make a difference, the size" he said, basking in the afterglow of their intimate moment and agreeing with what his uncle previously said.

Peter raised an eyebrow, intrigued. "Did you let him finish inside you?" he asked, his curiosity piqued.

"Yes! I can hardly believe I went through with it, but the urge was overwhelming. I craved it so much... yet there's something unusual about the situation," Derek replied, a hint of confusion in his voice.

"What do you mean by unusual?" Peter pressed.

Derek hesitated for a moment before continuing, "Well, his cum isn't leaking out of me, and he came quite a bit, more than a bit actually."

Peter chuckled knowingly. "That's because he released inside your omega canal. All of it is still settled deep within you."

A satisfied smile spread across Derek's face as he absorbed this revelation.

"Now, go wash up, you little slut," Peter instructed playfully to his cheating nephew. "I'll take care of Stiles while you clean yourself."

As everyone departed, Theo felt a rush of urgency and managed to slip away just five minutes later. An hour later, he found himself watching his omega, soon-to-be husband, Derek, walking down the aisle. Derek had just experienced an intense encounter with Stiles, who had an impressive endowment, but despite that, Theo was committed to going through with the marriage. He realized he still loved Derek deeply, even if he couldn't satisfy him in quite the same way Stiles had.

After the ceremony, and when they reached the hotel, Derek insisted on taking a shower first, avoiding any oral intimacy. However, Theo had other plans; he wanted to savor the remnants of Stiles's essence still inside Derek. He noticed how Derek's pussy was red and swollen from the earlier encounter, which only fueled his desire. That night, despite Derek's insistence on a shower, the evidence of Stiles's presence in Derek’s pussy still lingered, making Theo's heart race with excitement.

Theo would indulge and savor Derek's pussy at least twice a day, thinking about what Stiles had left behind. He took every opportunity to make love to Derek, using his five inches to pleasure him as much as Derek would allow. However, after the initial swelling subsided, it took a couple of weeks for Derek to regain some tightness.

A couple of months after their honeymoon, Derek's belly began to swell, which led to a tense conversation. Derek confided in Theo that he was sure Theo wasn't the father, suggesting he would sign divorce papers if that was what Theo wanted. Pretending to be oblivious, Theo encouraged Derek to share the entire story about how Stiles had thoroughly satisfied him.

Embracing his role, Theo found himself aroused by the details and that night, he eagerly devoured Derek's pussy, trying to replicate the experience Stiles had given him. They told their families that they had used a sperm bank for their child. Approaching their first anniversary, they planned a trip, while Derek's and Stiles’s son, Eli, would be cared for by his(Derek’s parents) grandparents during their getaway.
