You are wake up by the sound of the door closing. It's Harry, your uncle. You look at your cousin Kyle, who is still sleeping, and decide to go down the stairs, hearing your uncle's snoring
As Marcus gently descended the stairs, he saw his uncle, half-naked and asleep on the sofa. He licked his lips at the sight of his uncle's erection bulging through his boxers. He approached slowly, silently, and knelt between Harry's legs, beginning to kiss his crotch without waking him. The scent emanating from him was intoxicating.
Marcus's ministrations sent delicious tingles through his groin and lower belly as he lay there unconscious on the couch. He felt himself grow harder under Marcus's attentive lips and tongue, but it didn't register past the haze of exhaustion that clouded his mind. Even in sleep, his body betrayed him, responding to Marcus's touch with a hunger that went beyond mere lust.
Marcus opened his eyes slightly as he saw his uncle become completely hard. Gently, he pulled down his boxers without waking him, freeing his large, throbbing cock. Marcus's mouth watered at the sight of his uncle like this. He gently took Harry's length in his hand, beginning to kiss and tenderly lick the tip.
As Marcus began his ministrations on him, it was as if all the fatigue in his body dissipated and was replaced with an almost euphoric sensation. He moaned softly in his sleep, barely registering that he was being pleasured. The warmth and wetness surrounding his cock felt incredible against his sensitive flesh, sending waves of pleasure through him as Marcus worked diligently to bring him relief from the haze of exhaustion.
Marcus continued licking and sucking the tip of his uncle's cock, using his hands to stroke its long length, making sure not to go too fast or be too greedy so as not to wake Harry up.
Marcus's efforts were greatly appreciated by the subconscious part of his brain that was processing sensory information. It signaled to his body to relax further into the sensations and enjoy what was happening, despite the fact that he remained deeply asleep. His hips began to move slightly on their own accord, instinctively guiding Marcus's lips and tongue over his most sensitive areas with each pass.
Marcus moved away from his uncle's cock. He took off his clothes, leaving them completely naked, and very gently, he squatted down onto his uncle's lap. Before doing anything, he made sure he was still asleep. Seeing that Harry still hadn't woken up, he took the man's cock and guided it to his ass. He took a soft breath, beginning to slide down its long, thick, throbbing length. He bit his lip to keep from making any noise. When he was completely on top of his uncle's cock, he stayed still for a moment, making sure the man was still asleep. Looking at him, his uncle looked like a log, completely detached from reality thanks to sleep. With that, Marcus began to slowly move up and down on Harry's cock, biting his lower lip to keep from moaning with pleasure as he was filled by his uncle's cock.
While still deeply asleep, the pleasurable sensations coursing through his body began to register on a more conscious level. His mind was foggy and disoriented but slowly started to wake up, confused by the feelings of Marcus's warmth surrounding him and the tightness gripping his cock. He moaned softly, unsure whether it was real or part of his dream.
Marcus had his eyes closed as he continued to ride his uncle's cock, feeling its length fill his ass. He wanted to go faster, wanted more, but he had to be careful not to wake the man. He was so absorbed in the sensation of being filled that he ignored Harry slowly waking up.
"Uhn... that's... good..." his voice slurred, still half asleep. He arched his back slightly, thrusting upward into the tight warmth surrounding him. As he woke further, it became clear what was happening and a shudder ran through him at the taboo nature of their actions. "Marcus...?"
His eyes fluttered open to find his nephew's face just inches from his own, flushed and glistening with sweat as he continued to ride Harry's cock. It was like a fever dream come true but also eerily wrong in the harsh light of reality. "Wha...?" he muttered groggily.
Marcus's eyes snapped open, and he stopped, his uncle's cock fully inside his rectum. "U-uncle..." he stammered nervously. "I-I... well, I..." Marcus didn't know what to say; he'd been caught in the act.
"Don't stop..." Harry said quietly, his voice hoarse with desire and exhaustion. He reached up, running his fingers through Marcus's hair gently as he stared into his eyes. "I want you... but we shouldn't... should we?" The confused mix of lust and guilt was written plainly on his face.
Marcus let out a trembling sigh when he heard his uncle give him permission to continue. With renewed energy, he began to ride his uncle's cock enthusiastically, moaning each time it fully entered his ass. "Damn... if we shouldn't be doing this... why does it feel so good?" he said, his breath ragged between moans.
"Because it feels... good..." Harry groaned as the sensation of Marcus's tight muscles gripping his cock overwhelmed him once more. He reached down, running a hand over Marcus's ass cheek before sliding it between their bodies to stroke and squeeze at the base of his erection. "It feels... natural..." he murmured sleepily.
Marcus let out another moan as he felt his uncle begin to stroke his cock. "Fuck..." he said, continuing to ride the man's cock, riding up and down with enthusiasm. "Uncle... your cock... I love your fucking cock so much..." he moaned. "...it feels so good..." His hips thrust faster, searching for a way to push the man's cock deeper into his ass. "...fill me up, uncle... please."
As if in some hazy, dreamlike state, Harry felt the warmth and tightness of his nephew envelop him once more. The pleasure was almost too much to bear, but somehow it also grounded him in a way that nothing else could. He thrust upwards into Marcus's body, driving deeper than before as their hips slapped together in time with each other's cries. "God... yes..." he groaned, his eyes squeezing shut against the building pressure within him. "I can't... I need to..." The heady mix of exhaustion and desire clouded his judgment, making it impossible for him to focus on anything but the bliss coursing through his veins as Marcus rode him with an expertise that belied his age.
As they moved together, Marcus's breath came in ragged gasps as his uncle continued to fill him up with his hard cock. He moaned and groaned, feeling overwhelmed by the pleasure coursing through his body. "Oh... yes, Uncle Harry..." he gasped, pushing back onto the man's thrusts. "...I love it when you fuck me like this..." His nails dug into his own skin, leaving marks on his hips as he arched his back, taking him deeper still.
"Oh fuck..." Harry groaned, feeling himself approaching the edge. The sensation of Marcus's body milking his cock was almost too much to bear and combined with the deep pleasure radiating from his balls, he knew it wouldn't be long now. "Marcus... you feel so good..." he slurred through gritted teeth, thrusting upwards one final time as he felt the familiar sensation of release building within him. His hips bucked violently against Marcus's ass, his cock twitching and spurting as he came hard inside his nephew's body. He moaned loudly, arching back and clutching at the couch as wave after wave of pleasure washed over him. For a moment, the exhaustion he felt only moments ago was forgotten in the haze of lust that had consumed them both.
As his uncle came inside him, Marcus cried out in pleasure as well, his body tensing around Harry's cock with each spurt of hot cum. The sensation was almost too much to bear, but he welcomed it with open arms. "Uhn... Uncle Harry..." he gasped, riding the man's cock until they both finally collapsed together on the couch in a tangled mess of limbs and sweat-drenched skin.
With a contented sigh, Harry wrapped his arms around Marcus, nuzzling his neck as they lay together on the couch. The afterglow of their shared passion filled him with a sense of peace that he hadn't felt in ages, despite the lingering fatigue weighing down on his eyelids. He held his nephew close, feeling the steady beat of Marcus' heart against his chest as they both caught their breath. "I... I don't know what came over me..." he murmured softly, still struggling to make sense of their actions. "It was... incredible." There was a brief pause before he added hesitantly, "Thank you."
Marcus smiled weakly, his breathing ragged. "You're welcome, uncle..." he said softly, stroking his uncle's chest before giving him a tender kiss on the cheek.
"Hmm... you know," Harry mused, his fingers idly tracing circles over Marcus's stomach. "Maybe we shouldn't tell your father or Kyle about this. It might complicate things." He laughed lightly at the absurdity of the statement but quickly sobered up as he considered the implications.
"Or maybe... it doesn't matter," he continued, growing more uncertain by the second. "I mean, we're family, right? And sometimes..." He trailed off, unsure how much further to dig into this line of thinking.
"I don't think it matters either," Marcus replied softly, nestling closer to his uncle. "But... if you want, we can keep it between us." He kissed his uncle on the cheek again before pulling away slightly, looking at him with an expression that mixed curiosity and concern. "Are you okay?"
"Hmm? Oh, yes... I'm fine." Harry tried to sound reassuring even as he wondered himself how much of this was denial and how much was genuine acceptance. "Just a little tired... maybe I should get some rest after all." He yawned widely before sitting up, slowly disentangling himself from Marcus's embrace.
"Why don't you head back to bed, too?" he suggested gently, helping his nephew stand and steadying him as they both regained their footing. "We can... talk about this more tomorrow if you want."
"Alright," Marcus said softly, following his uncle's lead. "We can talk later, but... I hope you know that I won't tell anyone else about this, Uncle Harry." He smiled weakly at him before heading back up to bed.
As he watched his nephew disappear back up the stairs, Harry couldn't shake the feeling that something profound had just happened between them. It was wrong on so many levels, but there was no denying the intense connection they'd shared in those moments. Maybe tomorrow, when the haze of exhaustion had lifted and reality returned, he could make sense of it all... or maybe not. For now, he decided to head back to his room and try to get some rest before dealing with whatever new challenges the day might bring.
