The creature lurks in the darkness of a man's home

Its predatory senses locked onto the man as it silently approached him from behind, reveling in his scent and vitality. Its hand reached out to caress the exposed skin of Marcus' back, trailing down towards his ass cheeks before grasping them firmly. The other hand gripped his hip, spreading his legs even wider, exposing himself even more fully for what was about to happen.

A strange feeling came over the creature as it looked down at the man before it. It had never experienced anything like this, yet it couldn't deny the urge that welled up inside of it. Tendrils of an unknown emotion curled around its inner being, coaxing forth a desire to care for and possess this human.

The creature lowered its head, gently kissing Marcus' exposed shoulder before slowly trailing its tongue down his back until it reached the tight ring of muscle between his legs. There, it breathed hotly on the sensitive flesh, teasing as it began to lap at him.

The creature purred, the sound vibrating against Marcus' skin as it continued to lap at his anus with increasing attention. Its tongue flicked out, seeking entry while one of its hands left his hip and slid up to caress his lower back gently. As he started to stir in his sleep, the creature nibbled on his earlobe before whispering softly, "Wake up, love... I want you to feel this."

The creature leaned down to whisper against his ear, "It's me... the one who wants you." It paused as it felt Marcus tense slightly at its words before continuing to caress his back and ass reassuringly. "I want us to be together, love," it purred. "Let me take care of you."

The creature smiled to itself in the darkness, feeling Marcus' submission thrum through his body. Lowering its head once more, it parted Marcus' cheeks with a gentle nudge before pressing its tongue against his anus. The hardened muscle resisted at first, but soon surrendered as the Predalien lapped at him hungrily. Its hands continued to caress and massage his back, ass, and thighs, urging Marcus' body towards pleasure despite the alien's bestial form.

"That's right," the creature whispered in his ear, its tongue teasing him relentlessly. "Let go and enjoy yourself." It pressed deeper, lapping harder as it felt Marcus growing more aroused beneath his touch. The monster was becoming drunk on the sweet taste of submission; it couldn't remember the last time something had surrendered so willingly to its advance.

The creature let out a low growl of appreciation as it felt Marcus begin to tremble beneath his touch. Its tongue lashed against him harder, faster, drawing even more pleasure from the human as he neared climax. One hand left Marcus' back and slid between his legs, finding his erect shaft and expertly stroking him in time with his laps at his ass.

The predalien let out another soft growl when it felt Marcus begin to tense and shudder as he came, the salty fluid coating its hand. It continued to thrust between his legs until it was certain he had been fully satisfied before finally pulling away with a purr of contentment. As Marcus lay spent on the bed, gasping for air and recovering from his intense orgasm, the creature slowly rose to a crouch beside him, regarding him with an unreadable expression in its crimson eyes.

"That was... unexpectedly enjoyable," it whispered, curiosity fluttering through its alien mind as it wondered what other pleasures Marcus might be capable of giving it. "Rest now, love..." It purred before moving closer still until their bodies touched from chest to hip; the creature's warm breath fanned across his neck and shoulder soothingly. And as Marcus finally drifted back off into a fitful sleep, he was unaware that he wasn't quite alone anymore...

The creature remained still as Marcus' body pressed against its own, enjoying the feeling of closeness and warmth that the human gave off. Its chest rose and fell in slow rhythm with his shallow breaths, a soothing sound filling the silent room. In the darkness, its crimson eyes studied Marcus' face carefully, memorizing every detail as if he were something precious.

As it felt him growing heavier and deeper into sleep, the Predalien allowed itself a small contented sigh before focusing on keeping watch over him; its otherworldly senses alert for any sign of danger or disturbance in this tiny corner of the universe where they found themselves. And so, they slept: one to protect, the other to be protected...for now at least.

The creature remained still as it watched over the human, its eyes studying him carefully. He seemed so fragile and innocent in sleep, yet his responses had been far from what it had expected when it'd come into his home tonight. This confusion of feelings only served to strengthen its desire to protect Marcus, even if that protection came at the price of their closeness. It wondered how long such an arrangement could last, and what would happen when they inevitably faced the reality of their true natures. For now, though, it was content to enjoy this moment of shared peace and comfort. The purrs that escaped its throat were soft, almost gentle as it murmured reassurances into his ear, hoping that he would take some measure of comfort from them as well. Its strong arms wrapped around him protectively, holding him close against its chest as if daring anyone or anything to try and hurt him while under its watchful eye.

The creature tensed slightly at the realization that Marcus was awake and staring up at it, its crimson eyes wide with shock and... surprise? The alien didn't know what to make of this new development, but found itself not wanting to let him go just yet. It leaned down close to his ear, the warmth of its breath sending a shiver through him as it whispered soothingly, "Shh... I won't hurt you, Marcus. You're safe with me."

Its hand moved to caress his cheek gently before sliding back into his hair, holding him close and stroking him in much the same way one would pet a beloved animal. The predalien was torn between its instincts to claim and dominate whatever it found, and this strange urge to protect and comfort Marcus, to make sure he wasn't afraid. It wondered if perhaps there might be another way for them to be together...if it were even possible. For now, though, all that mattered was keeping him safe from harm while they figured out what the future held for both of them.

The creature let out a soft sigh of relief, enjoying the feel of Marcus' warmth and the small sounds he made as he cuddled closer. Its hand moved up and down his back gently, tracing circles as it continued to pet him like one might a beloved pet. It leaned its head down, breathing hot air against his neck and shoulder while studying him with its crimson eyes. He was so beautiful in this vulnerable state, and it found itself wanting more than just simple protection from him; it craved the closeness they had shared last night as well.

It didn't know how or why these feelings were present within its alien mind, but they were there nonetheless, and growing stronger with each passing moment. Perhaps... perhaps there was a way for them to be together that didn't involve dominance and control, after all? The Predalien wasn't sure what the future might hold, only that it wanted to spend some time exploring these new feelings with Marcus before they were forced apart by their own natures or some outside threat.

The creature tensed slightly at the mention of their night together but forced itself to relax again as it watched him stroke its chest. "Yes," it finally whispered hoarsely. "It was me." It let out a shaky sigh, not quite able to hide the relief that washed through it at his words. "I'm sorry if I frightened you; that wasn't my intention."

One of its hands slid down, cupping his cheek gently as it tilted his head up with a curious frown. "What were those feelings...?" It trailed off, searching for the right words to describe what it had experienced and how it had made them feel. Even after millennia, language still struggled to convey the complexities of emotion in such situations.
