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.

Her voice sounds soothing. "I want to have sex with you, human," she says. You try to move away, but she's strong and keeps a firm grip on your pants. With incredible strength, she rips them off completely. Her huge chest, several times larger than her head, is exposed in front of you. She looks at you with black eyes and smiles, revealing her rows of sharp teeth. "Don't be scared," she whispers again before starting to touch your penis gently.

Her touch is surprisingly gentle, almost comforting. It's as if she knows exactly what to do to make you lose control. You feel your breath quicken and a strange warmth spread through your body. Len slowly begins to stroke your shaft, alternating between slow and fast strokes, watching your reaction carefully. "That's it," she whispers in your ear, her hot breath sending shivers down your spine. "Let go."

Her breasts sway gently as she continues to stroke you. They're larger than anything you've ever seen, and they seem to defy gravity. With one hand, she fondles her giant breast while keeping the other on your cock, expertly working you into a frenzy. "You like that, human?" She whispers, leaning in close enough for you to feel her breath against your skin. You nod weakly, unable to form words as pleasure overtakes you. Len smirks and speeds up her pace, determined to make you hers entirely.

The pleasure increases with every stroke, and the sounds coming out of your mouth only fuel her passion. Her grip on you tightens, as if she's afraid you might slip away before she's finished with you. She leans forward, pressing their bare chest against yours so that you can feel every beat of her heart and every shallow breath she takes. "Come for me," Len whispers, her voice harsh and demanding as if this were a command rather than a request. You oblige her, finally succumbing to the intense pleasure coursing through your body.

You arch your back, shouting out your release as hot fluid erupts from your cock, covering Len's hand and dripping down onto the floor. She moans in satisfaction, feeling you shudder beneath her as you finally surrender to her power.

"Very good," she purrs, her voice satisfied. "Now we can continue." Before you even have a chance to catch your breath, Len roughly grabs hold of your hair and yanks your head back, opening up your throat for her entrance. Her black tongue flickers out, tracing the curve of your neck before plunging into your mouth, seeking release in your warmth and wetness.

The taste of herself fills your mouth as you feel her thrusting deeper, seeking to claim every part of you. Her tongue tangles with yours as if in some sort of twisted dance, each movement driving another sharp jab of desire into your core. You whimper and moan around her invading member, desperate for air but unable to dislodge the thick organ from its place inside your mouth.

Finally, Len pulls back, leaving a trail of saliva behind as she exhales roughly through your lips. "I think you're ready for more," she purrs, running a long finger along the seam of your exposed chest, tracing lazy circles that only serve to heighten the tension building between your legs. "You did very well for your first time. Now let me reward you."

She positions herself above you, guiding your engorged cock back towards her wet entrance. "Oh yeah," she murmurs as you slowly penetrate her warmth once more. With a soft moan, she pushes down, taking all of you inside and closing the connection completely. Her body wraps around yours like a second skin, and with every thrust, it feels like she's claiming another part of you for her own. "Fuck," she growls, arching her back in pleasure as your hips meet hers again and again. "This is what I need."

The feel of your flesh against hers sends ripples of pleasure coursing through her body, making it difficult for Len to focus on anything else but the satisfaction you're providing. Your cries and whimpers only serve to heighten her arousal further, driving her deeper into this forbidden union. She digs her nails into your back, leaving red marks as proof of their passionate coupling.

"You like it when I hurt you?" she whispers in your ear, breath hot and heavy against your skin. "Tell me." The thought of inflicting pain upon you only adds to the thrill she's experiencing right now; knowing that she can do whatever she wants with your body is exhilarating.

"Very well," she hisses, her breath hot against your neck as she drags her teeth along the skin. The pain shoots through you like lightning and focuses every last nerve on the act of lovemaking. She grips your hips tightly, her fingers digging into your flesh as she uses them to control the rhythm of their bodies colliding together. "Fuck me," she demands, pushing herself down harder onto you with each word. Her black eyes blaze with an inner fire that seems to consume everything around it; there's no question that this is an encounter like no other and Len won't let go until she has had her fill.

Her words echo through your mind, riding on waves of pleasure that seem to reach every inch of your body with each thrust. She feels impossibly tight around you, squeezing you like a vice as she rides you harder and faster. Len's cries and gasps fill the room, her voice rough and raw with need. Her huge breasts bounce rhythmically against your chest as she moves, taunting you with their perfection even while they distract you from the pain that's starting to build in your back.

You dig your fingers into her hips, trying desperately to find purchase as she takes control of this encounter. "Fuck," you gasp, feeling as though you're on the brink of release once more. The idea of surrendering fully to Len fills you with both terror and desire; part of you wants to fight back, but another part can't resist the power she wields over your body and mind.

Her breath catches in her throat as your hands grasp at her breasts. Her back arches further, pressing their bodies together with renewed urgency. "Yes," she hisses between clenched teeth, "feel them. Squeeze them." She rocks her hips harder against yours, driving deeper inside you with each thrust. Her nails scrape along your back, leaving thin red lines that burn and ache as much as the pleasure does.

With a wordless cry of release, Len bucks violently beneath you, her body going taut as she comes apart in your arms. You feel her muscles quiver around you, almost as if they're trying to push you out entirely. But instead, she clings tightly, determined not to let go until every last drop of pleasure has been wrung from both of you.

Her lips find yours in a bruising kiss, rough and demanding as her hands roam over your body, searching for any new pleasure spot they might exploit. Her tongue tangles with yours as she sucks on your bottom lip, drawing out every last moan and whimper from deep within you. "Mine," she growls into the kiss, her voice harsh and possessive. "You are mine now."
