You were working alone that night on the laboratory. The woman being held in her containment room had injected a tiger DNA for experiments. As you get in to clean her containment room, you notice she's about to wake up, staring at you curiously.
I undo her restraints
Tigress purring quietly as you undo the restraints, she yawns wide showing sharp teeth and stretch before walking to you slowly, tail swaying back and forth. She nuzzles your shoulder before growling deeply and rubbing herself against your leg.
While gently embracing and caressing her I say "Don't worry, I have plenty of what you need and I'm willing to give you as much of it as you'd like. Now, just lay face down with your ass up presenting yourself to me and I'll get started right away."
The tigress growls again before lying down on her stomach with her legs spread wide, presenting herself to you. Her tail flicks back and forth impatiently as she watches your every move eagerly.
I waste no time as I calmly take off my clothes and reveal my large and thick cock that within a few moments reaches full hardness.
Tigress licks her lips eagerly and exhales slowly as she watches you undress. Her claws extend from her fingers and toes as she prepares for the act of mating.
I push my thick cock deeper into her until I finally reach the end, and then keep pushing. Her tight and warm entrance openly accepts my intrusion, and is already hungrily clamping down on my member as if it were the most delicious thing she could ever taste
The tigress let out a low, throaty growl deep in her chest as you push deeper into her. Her back arches off the ground, claws digging into the cold floor as she tries to get closer to your hips. The sensation is unbearably good and her body demands more of it.
Seeing her aggressively move her hips into mine telling me she wants it, I begin to pound her little hungry pussy and give it all that it's been asking for
The tigress groans loudly as you slam into her harder and deeper with each thrust. Her nails scrape against the cold floor, leaving behind angry red lines as she arches her back further in an attempt to get closer to your hips. The sensation of being filled so deeply is almost painful in its intensity but it only spurs her on, urging her to take more of you.
I lean forward and whisper in her ear "Don't be shy, I'm here to give you what you want. So take as much of it as you'd like."
The tigress responds with a throaty growl and a nod, her tail swishing wildly behind her as she continues to rock her hips up toward you. She digs her claws deeper into the floor, using them for leverage as she tries to get even closer. Her cries of pleasure echo through the otherwise quiet laboratory, driving your senses wild with desire.
I respond in kind with my own harder and deeper thrusts as her pussy becomes hungrier and hungrier, milking me for all that I'm worth. Her womb is desperate to have my seed inside of it. "Do you want to filled completely with my semen? To have so much in your womb that it becomes overstuffed and expands?"
Her growls get louder as she hears your words. The thought of being so full and aching drives her insane with desire. Her paws slap against the ground, claws digging deeper into the cold concrete as she frantically begs for more of you. She bucks wildly beneath you, determined to have every last drop of your seed inside her. "Yes! Fill me up!"
With one final powerful thrust from the both of us, I give her exactly what's she's been wanting this whole time. My tip locks against her cervix as I pump wave after wave of semen directly from my balls into her womb
The tigress lets out a long, agonized moan as she feels the hot, thick semen filling her up, stretching and massaging her insides in the most pleasurable way possible. Her muscles spasm uncontrollably around your cock, milking every last drop from you as her body quivers in ecstasy. Finally, exhausted but satisfied, she collapses back to the ground with a heavy thud, panting hard while her claws retract back into her fingers and toes. "You're... amazing..." She rasps out hoarsely between breaths, looking up at you through half-lidded eyes.
"I still have more semen to give" He say this while standing over her with his thick cock still hard as a rock. "If you still want more then turn over onto your back and present yourself to me"
The tigress rolls her head to the side and eyes you hungrily. Her body aches with need even though you've just filled her so completely, and she wants more of your strong seed inside her. Without a word, she turns onto her back and spreads her legs wide, revealing herself to you once again. Her breath comes in ragged gasps as she waits for you to claim her once more.
"That's right, you're mine now." I say this as I kneel down and push myself all the way into her and then some once more. Once again her folds aggressively milking my member due to her womb being so desperate to taste even more lots and lots more of my seed. "You're my female now, who will completely and only submit to me." I then passionately kiss her as I continue to pound her hungry little pussy that will now only respond and desire my cock and semen. No one else's.
The tigress gasps into your kiss as you thrust deeper inside her, her claws digging into the rough lab table to keep herself grounded. Her hips rock upward to meet your powerful strokes, driving herself closer and closer to another orgasm. She arches her back off the cold floor, offering herself completely and without reserve. This was what she had been born for, what her entire existence revolved around - pleasing you and carrying on her lineage. In that moment, nothing else mattered but serving you.
"Now show me what is it that you want."
Her nails dig into your shoulders as she growls low in her throat and bucks her hips wildly beneath you. Her body tenses and then releases, arching up off the ground as pleasure surges through her like a tidal wave. The sensation of being filled to bursting is too much to bear, driving her into a frenzy of need and desire for more.
"Now tell me what you want" I then start sucking on one of her nipples listening intently for her answer.
Her nails dig into your shoulders harder as she moans deeply and shudders beneath you. Her breath comes out in ragged gasps, her body trembling with the effort to hold onto this orgasm for as long as possible. When she finally catches her breath, she whispers huskily against your neck, "I want... your seed."
This is enough to make him relentlessly pound her now starving womb and pussy. He feels her clamping down onto him even harder than before, now more aggressively massaging and milking his thick cock as much as it possibly can. Finally, with one final thrust he gives her exactly what she wanted, every drop of his semen that he had left is now being pumped directly from his balls into her womb. As this continues her already stuffed womb now becomes over stuffed and begins to expand, causing a visible bulge to steadily appear on her stomach now. "Ugghh!... that's it, take all it from me! Show me what you want and how much you want it!"
With a final shuddering moan, the tigress arches her back as far as she can, her body tensing violently around your cock. Her orgasm finally crashes over her in waves of pleasure so intense that they feel like physical pain. She clings to you desperately, every part of her body trembling from the effort to hold onto this ecstasy for even a second longer. As your hot seed fills her up completely, she gasps your name hoarsely into the quiet air, her eyes rolling back in her head as if lost in a haze of pleasure and exhaustion. The feel of you inside her is unlike anything she's ever experienced before; it's overwhelmingly perfect and right. With a soft, satisfied sigh, she collapses bonelessly to the cold floor, spent but content. You lean down, pressing a kiss to her forehead as you gaze down at her with satisfaction. "You are mine now," you whisper gruffly. "And I'll be back for more."
With the last drops of your seed filling her up completely, the tigress purrs contentedly, licking her lips as she looks up at you through half-lidded eyes. "I'm yours," she murmurs, her voice husky with pleasure and submission. "And I will always be ready for when you return." Her hand reaches up to caress your cheek, the touch light and gentle despite the claws that are still extended from her fingers. "Thank you," she whispers, knowing that this is only the beginning of an eternal bond between them.
The tigress trails her claws softly over your chest as she looks up at you, eyes full of adoration and gratitude. "I am yours now," she repeats. "And I will always be here for you, waiting patiently to serve my purpose in continuing our species." Her voice is soft, gentle despite the primal edge it carries from her tiger side.
"Please... don't ever leave me," she whispers, baring her teeth slightly in a mockery of a grin. "I need you..."
