Jag’s eyes widened as it shoved its cock against her sex, unable to penetrate her because of its massive size at first.

“No…no…no…no no no nonononoAAAAAIIII!” She broke off into screams as it finally pierced her lips, splitting her sex… indeed feeling like it would split the girls pelvis in half. She continued to scream and wail as it began to fuck her, her body arching up every time it would push in, and exhaling, even deflating, when it would nearly pull itself from her. It stretched her walls and filled her passage easily, straining her young body like never before. It wasn’t fucking her; it was using her as a glove upon its cock to get itself off.

The thick phallus pressed harder and deeper into her tight sex with each passing moment, forcing the young girl to arch her body up high with hard shove into her body. The thick tentacles around her breasts doubled their efforts, squeezing and tightening around her breasts even more, while the thin tentacles from his mouth tugged and pulled on her hard tits.

As Cukoo looked down at the young girl, he could see her small sex being stretched wider with each passing moment. The massive cock bulged and pulsed inside her tight body, beginning to press in and out slightly faster.

Cries of pain were soon intermixed with those of pleasure again as it took her, its massive cock piercing into her lips with increasing ease, her sex wet from both the water and her own nectar. Her head finally fell back between her tied arms, her tits thrusting upwards and bouncing even in its grasp as it tried to milk the fiery redhead, groping her breasts nonstop, sending shivers of delight up and down her body. The most terrifying part for her, however, was the knowledge that she was enjoying it… craving it maybe.

Cukoo could sense that the young girl was giving into the pleasure he was forcing on her. His massive phallus throbbed and quivered inside her tight body, growing slightly wider with each press into her small sex. Cukoo slowly slid his tongue back down towards her body and began to rub against her clit once again, pressing and vibrating against it while his thick cock pressed harder and faster into her body.

Cukoo leaned in close to the well-bound girl and said, "let yourself go." Once he said that, the thick tentacles around her breasts gave a quick, violent squeeze, nearly tearing the girl's breasts off her body. Cukoo's arousal was beginning to increase from the sight of the lovely girl flexing and squirming in front of him. As his arousal increased, a large amount of his hot, sticky seed began to produce inside of his blobbish body. Laughing loudly, he knew that she would soon be ready to receive all of it.

Jag shuddered in pain and pleasure as the two mixed. She could feel its cock swelling within her body, stretching her even further, quivering with what it would soon do to her. She couldn’t have stopped it if she wanted to. Instead she simply moaned and took it, her sex tight around him, clasping his sizable shaft as it pushed in and out of her slick tunnel.

Meanwhile its tongue found its way down to her clit and began to rub and tease the small button again, prodding it and pushing her towards orgasm. Out of nowhere, however, it gave her breasts a violent squeeze, pulling them out from her chest, nearly pulling them from her body. She gasped as the firm mounds giggled in its grasp, setting back.

As the huge shaft continued to press in and out of the girl's tight body, Cukoo's seed began to fill inside his massive blobbish form. Slowly, the thick phallus began to fill with the hot fluids, forcing his long cock to throb and bulge more inside her tight sex. His tongue pressed and rubbed against her clit, vibrating slowly as his large member forced itself into the young girl at an increasing faster pace.

As another loud laugh filled the lagoon area, Cukoo leaned close to the girl and repeated his words from before; "give yourself to me." His thick tentacles squeezed and tightened violently around the girl's breasts, forcing her tits to rise higher with each passing moment. As his thick phallus bulged and pulsed with the hot liquids filling him, Cukoo prepared himself to unleash all he had upon the lovely girl.

Jag could feel the thing bulge even more inside her, already past what she thought was her limit. Still, it pushed into her; still, she was taking it. Loving it to be exact. His words seemed mute. She had long since given her body over to this thing to play with. Her breasts being squeezed more and more, still burning with passion, added to her own pleasure, and she gripped around his cock frequently, ready to cum herself at this point despite the massive girth of the thing fucking her youthful sex.

Feeling the girl's sex gripping and squeezing aroudn his thick phallus, Cukoo knew that now she was ready to receive his seed.

The massive blob let out a yell, and sprayed a hot amount of seed into the girl's tight sex. The pulsing member began to throb with the large amounts of seed passing through it as more hot fluids were forced into her body. The thick cock thrust forward with each hot spray into her body, forcing the young girl to arch her back high with each spray.

The thick tentacles around her breasts doubled their efforts, squeezing and manipulating her soft flesh. The thin tentacles around her tits tugged hard, pulling her tits high off her chest. Cukoo laughed loudly once again as his massive cock bulged and throbbed with the large amounts to hot liquids being pumped into the girl's small body.

The thing yelled loudly as it began emptying itself into her, its seed hot, pouring more and more into her with each thrust. She didn’t know how an organism could hold so much, but she didn’t have time to worry about it. Jag’s tight womanhood filled with it seed quickly, completely, until it began to flow out of her sex around the still invading phallus, its hot feel on her sex lips and inside finally pushing the girl over the edge into her own orgasm, screaming loudly as her body went taut, arching into the air as the monster continued to play with her breasts and pluck and tease her stiff buds.

Cukoo felt the young girl reach orgasm. He laughed loudly as she reached her first climax... but it would not be her last.

As the hot seed continued to spray into her body, the thick tentacles around her breasts began to squeeze violently, nearly forcing the girl's breasts to rip off her body. Her hard tits shot high off her chest with each tight squeeze, while the thin tentacles around them pulled and tugged as hard as they could.

Looking down, Cukoo saw his hot fluids pouring from her sex lips. He knew that her body had been filled moments after he began to shoot the hot liquids into her, but he has much more to release. As the massive phallus filled with more seed, it throbbed and bulged inside the girl's tight body, nearly tearing the young girl in half. His long tongue pressed as hard as it could against her exposed clit, trying to force the girl into an unending chain of orgasms.

Jag never came down from her orgasm. Instead she found her chest leaping into the air as it was gripped tightly by the thing’s tentacles, too tightly, painfully, although her just barely masochistic tendencies just made her even more aroused.

She felt as though it was going to split her insides as it continued to swell and release more and more of it’s hot load, her tunnel filled, the sticky cum flowing out of her sex around the invading shaft even as it fucked her and pushed more and more in, each thrust would result in a squirt of enormous amounts of its release from her. Her tightly bound position just turned her on even more, and she went from one climax right into another.

The young girl was now in a near perfect state of pure arousal, her body giving orgasm after orgasm. Cukoo's laugh echoed through the air as his massive phallus swelled and gave another violent shove into her tight body, spraying another load of hot seed into her small belly.

The thick tentacles around her breasts squeezed like they never had before, nearing ripping the girl's breasts off her body. They tugged and pulled on her soft mounds of flesh, forcing her tits to shoot higher into the air with each squeeze.

Looking down, Cukoo could see the girl's small belly beginning to swell from the massive amounts of hot fluids being pumped into her. The thick cock throbbed and swelled with each violent shove into her body, forcing more sticky seed to pour from the sides of her sex lips. The massive blob knew that he was now on the verge of his own climax, and the lovely girl would be forced to take it all.

Jag screamed as it yanked her breasts far too harshly, as if it were trying to pull the young woman’s firm globes from her chest. She was unable to do anything about it in her position though so she simply continued to cry out in pain and pleasure at the same time as it pushed more and more of its seed into her. Under the false belief that it was cumming inside her, she wondered how long its orgasm could possibly last, not knowing that it was only approaching its own release.

Her normally flat, toned belly was swelling visibly with the copious amount of its liquid that it was pouring into her snatch, even as huge amounts of the thick stuff literally sprayed from her cunt with each plunge into her from the pressure. If not for the pleasant little helpers implanted in her by the labs (although unbeknownst to her), she likely would be in even more pain and possibly mortal danger from her stomach rupturing. Instead, the microscopic machines were kneading and relaxing her muscle tissue and allowing it to stretch to far more than its usual size.

As Cukoo's climax grew closer, the massive blob leaned in closer towards the lovely girl, saying only four words.

"Let it fill you."

With a massive, watery yell, Cukoo unleashed a wave of searing hot seed into the girl's already filled sex. The thick phallus inside her body swelled and heated from the final wave of hot fluids flowing through it, as the massive shaft forced as hard as it could into the young girl without tearing her in half.

The thick tentacles around her breasts gave one last violent squeeze at the sticky seed poured from her small sex, forcing her hard tits as high as they could go off her chest. As his dark eyes gazed down at the well-bound girl, her belly and swelled fairly high from the huge amounts of the hot seed still pouring into her small sex, as Cukoo gave one more violent shove into her. Cukoo wanted every last drop of sexual energies and juices from this lovely girl to the point where she would simply pass out, drained of everything she had.

Jag’s tight walls continued to milk him for more even as he erupted into her, her belly swollen with his seed, the sticky substance oozing from her sex lips around him even as he thrusted into her, filling her with more. She couldn’t say anything, and her eyes were rolling back in her head from pain and exhaustion. Her body began to go limp, still conscious but nothing more than a puppet upon his shaft to fuck. Her breasts bounced painfully, the expression somewhat evident on the girl’s face.
