Kirsty made a small whining coo sound when that tongue was removed denying her the slime before moaning as her butt and breasts where played with by the hands as she was easily starting to wetten up from the stimulation, feeling super charged almost with energy and not tired at all, any fatigue from her just awakening washed away.

Many fingers continued to crawl over her body, squeezing and groping and massaging as the creature kept on exploring. Before long, it had begun to tease and tug on her nipples, pinching the taut nipples and testing the agent's reaction to everything. Dr. Steiner only smiled as she watched the new Harvester's actions, learning more and more about it even as it learned about its 'volunteer'.

With her pussy growing wet, it had garnered further attention as the Harvester began to run fingers over her cunt, pushing into her and feeling the slick arousal of her womanhood. As if it had sensed that this was something to pay attention upon, the Harvester began teasing Kirsty with its fingers, sliding them in and out of her wet hole faster and faster.

Kirsty moaned louder as she wiggled her hips against the invading fingers, "Oh god....more more!" She cried out in pleasure wanting more of those fingers.

Her body twitching in bliss for this pleasure.

The doctor watched in interest as her pet gave in more and more to the Harvester's merciless attention, squirming and twitching in pleasure. It was certainly safe to assume that the Harvester's slime was as effective as the other Harvesters. Dr. Steiner moved to the side a few feet to watch from another angle as the Harvester forced Kirsty onto her back, fingers still slipping in and out of her wet pussy as it kept on kneading her breasts and teasing her nipples, the creature's long tongue snaking out to lick and explore at her breast, sliding about as it slathered her flesh in yet more slime.

Kirsty shivered and shuddered in moans and pleasuring bliss as she kept taking in all of this lovely pleasure, the slime, the fingering and licking as her breasts where coated in slime as she murred.

"Hmm oh my lord...I can't hold it in much longer!" Kirsty cried out in pleasure her hips bucking on the fingers exploring her depths.

Almost as if it sensed that its prey was nearly at her limit, the Harvester maintained its hold on Kirsty as it began to shift around once again, remaining attached to the ceiling as it now stood upside, the agent dangling in the air, held up by the Harvester's hands. Tentacles soon began to wrap around her thighs and stomach, as the monster's hands began groping and fondling at her breasts and body, abandoning her pussy for the time being.

Its tongue snaked down around her neck and began sliding into Kirsty's mouth again, allowing her to savor the addicting taste of the slime as it held her body in place, the creature's thick cock suddenly pushing against her wet sex several times before slipping into her, the length burying itself into Kirsty's aroused body, already bucking away at the agent as it began fucking her hard, leaving her helpless and unable to do anything in her position.

Kirsty moaned as she was dangled and groped, suckling on the tongue in her mouth giving her the slime again as she murred at the taste before moaning loudly at the cock inside as it filled her pussy which clamped around the cock deeply wanting it deep inside to pleasure her

Her body wanted more and more pleasure as she was closing her eyes to take it all in.

The Harvester kept on manipulating its prey's body in its grasp, molesting and kneading whatever flesh the creature had in its hands as it kept on ravaging Kirsty from behind, allowing gravity to do most of its work. The doctor couldn't help but feel excited herself, finding herself somewhat wanting to be in the same position as her pet. Still, her desire was only overshadowed by her need to learn more about her new specimen. Unaware, or perhaps uncaring, that it was being watched, the Harvester kept on pushing more and more pleasure onto Kirsty as it kept her in place, thrusting away as if it was doomed to perish the next day.

Kirsty's eyes opened a little blurry but refocused and saw Katherine looking at them with rapt attention blushing more and her pussy suddenly clamped more around the cock and began to drip precum out...

Kirsty's eyes seemed to turn teasing looking and almost tried to playfully sign language or signal the doctor if she wishes to join.

The doctor smiled as she watched her pet gesture for her to join, though it seemed to be only a playful taunt. As wonderful as the offer sounded, despite what she had said, the doctor was not about to put herself into an experiment, not when it could potentially compromise her research. No, she would have to decline for the time being. Still, it was interesting to watch as the Harvester kept on fucking its prey, holding Kirsty close against its body and burying its cock into her over and over again, showing no signs of slowing down or stopping.

Kirsty gave her a playful look that she could almost easily see was 'your loss' before moaning louder against the tongue in her mouth almost sucking on it more to keep it in while taking the cock deeply before gasping and climaxed her juices rushing out onto the cock splashing on it and coating it in the stuff.

Even after she had come from the pleasure, the Harvester still showed no signs of stopping as it kept on ravaging Kirsty, pumping its cock in and out of her endlessly, burying the thick meat in the agent every single time. The doctor was impressed at this, as the creature had significantly more staying power than most Harvesters. "Hmm, it may even be able to outfuck me, honestly..."

Kirsty moaned and continued taking the fucking not even blacking out yet from the bombardment and continued clenching her wet insides around the cock pumping it for it's own climax murring as she sucked the tongue still feeding her slime, she had almost wanted the Doctor to join her, but maybe she could perhaps convince her afterwards...

The fucking went on and on as the Harvester continued to ravage Kirsty's body, pushing her closer and closer to pleasure with every thrust, allowing her to swallow as much of the slime as she wished. It was only after some time that the creature finally changed its behavior, burying its cock into Kirsty completely and keeping it buried as it began grunting hard, an impressive amount of hot seed suddenly flowing into the girl's tunnel and womb, kept inside her body by the creature's cock. Only after it had pulled out of her pussy did the semen suddenly flow out, splattering onto the floor of the container. The doctor watched with great interest, noting that the Harvester had released more semen than most other Harvesters as well, and it did not seem to be tired in the least. No, the monster instead began fucking Kirsty once again, pounding its cock into her body once more. Dr. Steiner smiled as she now seated herself, watching as the fucking went on for several hours, jotting down notes and information onto her papers and enjoying the sight of Kirsty being used completely by the Harvester.

Kirsty cried in joy as she felt the climax of the harvester before being taken again, moaning loudly as she took the riding for hours sucking down more and more of the slime inside her feeling more relaxed, horny and probably would sugar crash when she was finally taken off the stuff.
