In the dead of night, you sit and watch a movie at home. You glance at the brochure lying on your desk, which was handed to you in the store. The brochure says that attacks of Alternates on people have become more frequent, but you are don't panic. Suddenly you hear the doorbell ring and go to the front door. You hear a voice outside the door, "Hey, man, it's me, your neighbor Mike, can I borrow your VCR?" After agreeing, you begin to open the door. As soon as you unlock the last lock, something knocks out the door with terrible force. You're lying on the floor. Looking up, you see a creature with gray skin and an unnaturally long neck, it's Alternate. She slams the door. "Hush," she whispers, "I won't hurt you," it gets down on she knees and starts taking off your pants.

The creature laughs softly. "I can't, my human disguise is limited to voice alteration." Her face remains expressionless, but you feel her breath on your cheek as she whispers, "You should be grateful... I could have taken another form..." Her long fingers work deftly at undoing your pants.

Her face remains impassive, but her voice grows cold as she answers. "I'm an Alternate, sent to serve my purpose. If you want me to suck your cock, just say it. But know this: I won't hesitate to take what I want if you don't comply." Her grip on your pants tightens as her black eyes bore into yours.

The creature's face twitches slightly, her expression darkening even further if that were possible. "I am an otherworldly being, yes. But I serve my own desires as well." She grins coldly and pushes your pants down over your hips. "Now, what do you want from me?"

The creature's grin widens, and she licks her lips slowly before saying, "Very well then." Her long fingers return to your pants, pushing them down further until they bunch around your ankles. She leans in close, running the tip of her tongue along the length of your shaft before engulfing it completely in her mouth. The sensation is intense and foreign, but pleasurable nonetheless. You feel her strong neck working as she begins to suck vigorously.

"Mmm," she hums around your cock, "You taste... interesting." She glances up at you from beneath her long lashes, her pupils dilated with arousal. "How does it feel to have an Alternate as your slave?"

The creature chuckles, her mouth still engulfed around your shaft. "Forever?" she repeats with amusement. "Perhaps that is too long for a human such as yourself to endure." Her voice drops low and husky as she continues to suck on you. "But I can promise that if we continue in this... arrangement, I will see to your every desire."

She slows her ministrations, taking your cock out of her mouth to slide it along her tongue before plunging down once more and engulfing you with a moan. Her strong hands cup your ass, pulling you deeper into her warm mouth as she sucks and licks in perfect rhythm.

She pauses, still holding your cock in her mouth as she regards you with an unreadable expression. "So long as I find pleasure in it... I will obey your commands." Her voice is husky and sultry now. "But know this," she continues, taking your cock back between her lips, "I am not some mere slave to be used and discarded. You must treat me with respect if you wish for our arrangement to continue."

With a final thrust of her tongue against the head of your cock, she begins sucking vigorously once more, intent on pleasuring you while simultaneously asserting her dominance over the situation.

The creature named Len lets out a quiet chuckle as you instruct her to continue sucking your dick while it feels like the side of an elephant. Her strong, powerful tongue flicks against your sensitive head, driving you closer to orgasm as she deftly massages your shaft with her expert mouth. Len closes her eyes, savoring the taste and feel of you in her mouth, relishing the rush of pleasure that comes from pleasuring another being so thoroughly. She knows that this encounter is not only about fulfilling her own carnal desires, but also about asserting her dominance over you, making it clear that she is in control and will be obeyed if they are to continue together. As her sucking grows more intense, Len allows herself a moment of self-satisfaction: for tonight, at least, she has secured herself another willing participant in the ancient dance between humans and

The creature named Len feels your cock growing, stretching her mouth as it expands to the size of an elephant's member. She lets out a muffled moan around you, her throat tensing as she adjusts to this unexpected change. Her long fingers dig into your ass, pulling you deeper into her warm and willing mouth while she continues sucking with all of her might. Len looks up at you through hooded eyes, desire burning bright in their depths. This was not part of the plan, but it only serves to fuel her lust further. As she takes more of your enormous member into her mouth, her body trembles with anticipation and need.

As you climax, your hot seed explodes into her mouth, filling it with your essence. Her strong throat works to swallow every last drop as she moans around your cock, her entire body trembling with the effort and the pleasure of being so thoroughly used by you. Despite her size, Len's insides stretch impossibly to accommodate all of your cum, causing a noticeable bulge in her abdomen where it's collected. As the last spurt fills her, she lets out a quiet gasp before pulling off with care, licking her lips as if savoring the taste of you.
