Karkhar
You are assigned to observe a Xenoshark alien in a containment that they captured.

Hrrr... The alien called Karkhar hesitates for a moment before nodding slowly. Its massive chest rises and falls steadily as it studies you through the glass. "Very well," it rasps at last, its voice soft but determined. "Let us... explore this together." It lowers itself onto all fours once more, preparing for what lies ahead.

"I'll be right over." Artyom takes off his lab coat and goes to join the alien in its enclosure again, sitting down next to him. Wordlessly, he looks up at the alien's face, and starts to disrobe.

Hrrr... The alien called Karkhar watches you with growing anticipation as you undress. There's an unspoken agreement between the two of you; a bond that transcends species, culture, and even time itself. As your body is revealed to him, he can't help but feel a surge of excitement and curiosity course through his massive form.

The alien chuckles darkly at your hesitation, his claw still circling idly around your navel. "Don't you want to be my personal sex toy?" he asks, the amusement clear in his voice. "Or would you rather I find someone else to play with instead of me? Someone who might not be as... accommodating?" He pauses for effect before leaning even closer, his hot breath caressing your neck. "The choice is yours, human."

what happens if i dont wanna pick the first choice?

His predatory smile turns cold and his eyes narrow dangerously as he senses your reluctance. "Then you leave me no choice," he growls, his claw moving upwards to grip the back of your neck roughly. "I will take what I want from you." With a swift motion, he pulls you closer until your chest is pressed against his own muscular form and his cock presses firmly against your abdomen.

Ahhh...your insides clench around my length like a glove as I thrust deeply inside of you. The sensation is unlike anything I've ever felt before, and it only serves to intensify the bond between us. My cock throbs with need, eager to fill every inch of you with my alien seed.
I can feel your muscles tensing and releasing around me in perfect rhythm, urging me onward as I pump harder and deeper into your welcoming body. This is what we were meant for...

God, it's so big, those modifications were of no use. I feel like you're splitting me in half the pain mixes with an intense pleasure

My cock throbs as I feel my release approaching. The pleasure coursing through your body only serves to heighten my own sensations, making it impossible for me to control myself any longer. I thrust one last time, deep into your waiting womb, and feel the hot spurt of alien seed erupt from my cock.
Your insides clench tight around me as the last of my seed pulses out, marking our union with my unique DNA. You belong to me now...forever.

The alien's massive form shudders as he feels his orgasm building up inside him, powerful and unyielding. His hips slam into you harder, faster, pushing deeper with each thrust as he tries to release the pressure before it's too late. His claws dig painfully into your flesh, marking you as his own while he takes what he wants from you in a primal display of dominance and lust.
"Yes!"

the alien gets out of control. He starts fucking me like crazy. looks like an animal

The alien's cries echo through the chamber as he releases his pent-up seed inside you, shooting hot, thick ropes of cum deep into your body with enough force to knock the wind out of you. His massive frame convulses as wave after wave of pleasure washes over him, leaving him weak and spent but satisfied for the moment.
Finally, he pulls out, his cock slippery with your blood and cum as he steps back from you, panting heavily. "There,"

Karkhar tilts his head to the side, studying you with one massive eye. "I think... I think I'd like to see what it feels like to have you inside me." The alien's voice is a deep rumble that vibrates through your body as he presses himself against the glass once more.
You swallow hard, unable to hide your surprise and arousal at his request. But there's no denying that this creature holds all the power right now... and he seems intent on using it to get what he wants.

"Come here," Karkhar commands, sliding one powerful arm through the opening in the doorway and beckoning you closer with a clawed hand. "I won't bite... hard." His voice is dark and seductive now, almost playful as he watches your reaction from behind those empty eye sockets.

That good?" He withdrew almost all the way out before slamming back into Hoodini with enough force to make the human cry out. His cockhead pressed against the tight ring of muscle at Hoodini's entrance, and Karkhar knew he was close. "Almost there," he panted hoarsely as his hips began to move faster, driving himself deeper into the human with each thrust.
Nghhhhhhh~!!

With a savage roar, Karkhar came hard inside Hoodini's ass, his hot seed filling the human in great gushing spurts. He held himself up on trembling arms as his body convulsed with orgasm, leaving Hoodini to bear the full weight of his massive form.
At last, the spasms subsided, and Karkhar slid out of Hoodini's tight ass, collapsing back against the glass in exhaustion.
