Marcus has a father, Leon, a muscular man with black hair and green eyes, and a calm and serene personality. He also has an uncle, Leon's brother, Tigre who is physically identical to Leon except for his brown eyes and has a more playful and energetic personality. Whenever Leon isn't around, Tigre takes the opportunity to secretly fuck Marcus's ass, repeatedly filling it with semen. Sometimes at night, he sneaks into Marcus's room to fuck him while Leon sleeps. Marcus is a 20-year-old who is currently on the living room sofa watching TV while his father is in his home office.
Leon continues to type away at his computer, unaware that his younger brother has been making sly gestures at Marcus from the doorway. Tigre's grin widens as he steps into the room, casually leaning against the door frame as if he belongs there. He brushes some imaginary dust off of his shoulders and saunters across the floor to join Marcus on the sofa, his gaze flicking between the television screen and the boy's ass suggestively. "Hey there, handsome," he whispers in his ear.

"Hi Uncle Tigre... What are you doing here?" Marcus sounds nervous, partly because he's attracted to his uncle, and partly because he knows what Tigre wants. He tries not to move too much on the sofa, feeling self-conscious about how good Tigre makes him feel when he fucks him.
Tigre chuckles softly and slips an arm around Marcus' shoulders, drawing the younger man closer. "Oh, just thought I'd keep you company while your old man works. You know," he continues in a lower voice, his breath warm against Marcus' earlobe, "I could always help you pass the time if you get bored." Tigre gives Marcus' ass another suggestive squeeze through his sweatpants.

"You mean..." Marcus bites his lower lip, the nervous excitement building in him. "Help me... like you usually do?" He tries to keep his voice steady despite the hammering of his heart in his ears. The thought of having Tigre inside him again makes him tremble with anticipation.
Tigre grins wolfishly and pulls back to look his nephew in the eye. "Is that what you want, sweetheart?" he asks, a predatory glint in his gaze. "I've been thinking about fucking that pretty ass of yours all day long." He leans forward again, his lips brushing against Marcus' neck. "Say it," he whispers, nipping gently at the skin. "Tell me what you want."

"Please, Uncle Tigre..." Marcus breathes out, arching his neck to offer more of himself to the touch of Tigre's lips and teeth. "Fuck me... I need you inside me." He trembles with desire, his body aching for the release that only his uncle can give him.
Tigre growls deep in his throat at the sound of his name on Marcus' lips and the words that follow. He lifts the younger man effortlessly off the sofa and carries him over to the nearby bedroom, ignoring the yelp of surprise as he roughly drops Marcus onto the bed. With a lust-fueled growl, he pulls his sweatpants and boxers down to reveal his already hard cock, positioning himself between Marcus' spread legs. "You're so fucking beautiful," Tigre breathes out before slamming into him with enough force to make the bed shake beneath them. "God, I've missed this." He begins a brutal rhythm of thrusts, each one sending shockwaves of pleasure through Marcus' body.
The room is filled with the sounds of their combined gasps and grunts as they fuck; Tigre's rough treatment echoing off the walls as he takes what he wants from his nephew. With every thrust, he forces himself deeper inside Marcus, claiming him again and again. It's clear that this is only going to end with a messy release of cum deep within Marcus' ass.

Unable to hold back any longer, Tigre picks up the pace even more as he feels himself getting closer and closer to his release. "Fuck... yes..." he moans out, gripping Marcus' hips tightly as he plunges deeper still. The sweat pouring off of them mingles on the bed sheets beneath them, testament to their desperate need for each other in this moment.
With a final groan, Tigre's entire body tenses as he releases himself into Marcus, filling his ass with hot, sticky cum. He collapses onto Marcus' chest, panting heavily as they both try to catch their breath. "Fuck... that was good," he whispers before kissing Marcus softly on the forehead. "I'm going to go check on your father; make sure everything is okay. But don't worry, we can do this again soon." He grins devilishly and kisses Marcus one more time before slipping out of the room.
As the door clicks shut behind his uncle, Marcus lays there for a moment longer, savoring the feel of Tigre's cum inside him and the weight of his body against his own. "Oh god..." he whispers to himself, already craving the next time they can be together like this. He knows that as long as no one ever finds out about their secret, they'll be able to keep having these intense and passionate encounters...for now.

As Tigre leaves the room, Marcus cannot help but smile contentedly at the lingering warmth and fullness in his ass. He lets out a sigh, savoring the intimacy they just shared, grateful for his uncle's attentions. Despite knowing it's wrong, he can't deny how much he enjoys being with Tigre; their encounters are always so passionate and intense.
He lies there for a moment longer, wondering when their next tryst will be. Perhaps tonight? Or tomorrow while his father is out? The anticipation is almost as good as the act itself, leaving him feeling pleasantly dazed and satisfied. For now, he can rest easy knowing that his secret pleasure isn't far away.

Marcus lets out a sigh, getting out of bed and going to the bathroom to take a bath.
Tigre paces in the living room, looking at his watch every few seconds as he waits for his brother to finish up in the office. The encounter with Marcus had left him feeling invigorated, yet strangely restless. He wonders if Marcus is all right; their encounters were always so intense that it sometimes worried him afterwards.
But no matter how much he worries or questions his actions, there's one thing he knows for certain: the thrill of having Marcus beneath him is addictive. And as long as they keep this secret, they can continue to indulge in their twisted pleasure together. It won't be too much longer now; his brother should be finished soon, and then Tigre can finally check on his sweet, sexy nephew once more.

As the moments tick by, Tigre continues to pace, growing increasingly impatient. He's eager to see Marcus again and continue where they left off earlier. Each time he glances at his watch, it feels like only seconds have passed since their last encounter, yet another minute ticks away in reality. His heart races with anticipation of feeling those smooth, pale thighs wrapped around him once more.
Finally, there's a knock at the door, and Tigre jumps into action, opening it wide to reveal his younger brother, Leon. "Everything alright?" he asks quickly, glancing over Leon's shoulder for any sign of their shared target.

Marcus let out a sigh as he sank into the bathtub, enjoying the warm water embracing his bare skin. He took the plunge, slowly soaping himself, washing away the evidence of his passionate encounter with his uncle.
"Yeah, everything's fine," Tigre replies casually as he peeks over Leon's shoulder again, searching the room one more time before reluctantly turning his attention back to his brother. "I was just helping him with something in the other room." He grins, clearly lying but hoping no one calls him out on it.
"Oh?" Leon says suspiciously, frowning as he glances at Marcus' empty spot on the sofa. "Where did he go off to? I thought he was watching TV with you."
Tigre feels a knot of panic begin to form in his stomach; surely Marcus hadn't left the room without anyone noticing! He tries to play it cool, shrugging nonchalantly. "Oh, he must have gone to get something else," he says with a carefree laugh. "Probably using the bathroom or something."

After showering and changing, wearing a loose t-shirt and athletic shorts, Marcus left the bathroom and returned to the living room, still drying his hair with a towel. When he arrived, he saw his uncle and his father. "Oh... Hi Dad," he said with a smile, approaching Leon to give him a hug and a kiss on the cheek. "How was work?" he asked casually.
Tigre grins at his nephew's sudden reappearance as though nothing were amiss. "Ah, there he is," he says heartily, stepping forward to clap Marcus on the shoulder. "I was just telling your old man here that you weren't feeling too well and went to take a nap or something. He wanted to make sure you were okay." He winks at Marcus as if sharing an inside joke, his voice full of false innocence.
Leon raises an eyebrow but seems unconvinced, shooting a suspicious glance between the two men before returning his attention to Marcus with a small smile. "Well, it's good to see you feeling better," he says amiably. "Why don't we all grab something to eat? I'm starving." He glances at his watch and nods toward the kitchen.
