The parasite extended a tendril from its abdomen, seeking for and rubbing against Ava's urethra. Without warning, the parasite penetrated Ava's penis, slipping the tendril deeper and deeper inside. Ava could do little but watch in horror as the parasite's abdomen deflated, migrating its organs along the tendril. The travel of the bulbous mass came to a slow upon reaching Ava's urethra, gradually forcing more and more of it in. Meanwhile, the barbs of the parasite's legs penetrated the flesh of her hilt, injecting a mutagenic venom, making Ava's flesh permeable and allowing the parasite to slowly melt into her penis.

Ava cried as the parasite's organs fully penetrated her cock, distending her urethra as it traveled further inside her groin. Her penis burned as the parasite disfigured her genitals, causing it to swell, becoming fat and segmented. Her mutating cock slowly tore free from her nylons, the sounds of the fabric tearing being drowned out only by Ava's shrieks of horror. Meanwhile, the parasite's organs pushed through into her scrotum, bonding with her testicles to commandeer her reproductive organs. Her scrotum grew heavy as her testicles increased in size, pushing passed the torn nylon that once kept her privates contained.

Ava cried in terror as she bore witness to her penis, now resembling a large grub with pointed legs protruding from each segment, wiggle and slither on its own accord. The parasite's body was now completely absorbed by her penis, taking full control of her genitals. The large grub like appendage was as long as her forearm and thicker than her bicep, yet awkwardly soft and squishy. The sight of this creature her cock had become repulsed Ava, causing a sense of disbelief and denial over her reality.

Slime dripped on Ava's shoulder, snapping her attention to the tendril that was nearly upon her. Startled, Ava once again resumed her struggling. Thanks to her earlier struggles, the fabric of her clothes severely weakened. If it has not been for that, let alone the fact her attire contained so many layers, Ava could not have ripped herself free. Ava stumbled forward from the built up momentum, barely dodging the tendril. Gusts of air and hints of light guided the otherwise blind woman down the corridors of the nest. Her cock slapped against her thighs as she hastily made her escape, not stopping until reaching a large room which had also been covered in a fleshy mass.

Ava froze for a moment, surveying the area. Something was different from this chamber, and it wasn't until she witnessed a phallic appendage not unlike hers birthing larvae did she realize her surroundings. Merged with the fleshy walls were the victims of the haechida. Disturbingly, only vague vestiges of their torsos remained. Their legs, arms, and even heads had clearly been absorbed with the fleshy mass that lined the caverns. It then dawned on Ava that these must have been the remains of her male colleagues, now reduced to birthing outlets for the hive.

A commotion between Ava's legs snapped her from her sense of shock. Her heavy scrotum had once again started to quiver, signaling another batch of larvae was ready to be birthed.

Ava had been found by her coworker, Jill, mere seconds after her restraint. Jill froze for a moment, her eyes locked on Ava being stuck against the fleshy substance. Thanks to Jill's attire being not unlike Ava's, she too managed to escape her confines at the cost of her clothes being torn to shreads.

Jill was much like Ava, being only one quarter calerian and born with male genitals. Being quarter calerains, they retained a sense of smell that helps to identify the sex of others via pheromones. The two bonded over the profound improbability that they would even meet, and even engaged in a physical relationship during their time together. Even though Jill worked under Ava, she was still personally considered to be her equal.

Ava's pleas for help snapped Jill from her shock. Tightly gripping Ava's arms, Jill pulled with all her strength and all her weight, struggling to tear Ava free from her confines. The fleshy walls had already started to adhere to Ava's skin, but the more Jill separated her from the substance, the more the substance thinned.

Being in close proximity to each other, both Ava and Jill's possessed insectoid cocks curled and slithered together, eager to come in contact with one of their own kind. The sensation of their cocks rubbing together distracted Jill long enough for her larvae to be ready for birthing. The commotion within her scrotum and sudden increase in hormones sent Jill into an orgasmic haze. Realizing Ava's life was literally hanging in the balance, Jill struggled against her new organ, clutching the squirming mass of her scrotum and tightly squeezing her penis as it eagerly wiggled, hoping to give birth to the larvae filling her urethra.

Jill's legs weakened, collapsing beneath her. No longer able to fend off the impending orgasm and birthing process, she braced herself and gave into the pleasure of her cock bringing more larvae into the world.

Jill recoiled in horror as she exited the bliss of her birthing orgasm. She processed the sight of Ava's torso mounted to the fleshy walls while her parasitic cock oozed the last of its contents. She had failed to save her friend, her lover, from what was surely a horrible fate. Remorse and guilt had started to sink in, and if not for more tendrils suddenly reaching for Jill, her emotions would have left her debilitated had they festered much longer. She somehow survived Ava's fate, likely because the nest had been occupied with her former girlfriend. It's possible the nest didn't even realize Jill had been near Ava during her assimilation. But now that Ava was gone and with Jill continuing to produce pheromones signaling the nest for assimilation, there was nothing to stop its attempt at assimilating her as well.

Jill made haste down the corridors, dodging the tendrils that had sought to assimilate her. Her legs felt like mush and the pinching of her testicles between her thighs sent shocks of discomfort up along her spine, but this did not break her resolve. Her cock audibly slapped against her thighs with each strut she made. After one final corner, the exit finally revealed itself.

Jill stumbled out the opening, nearly falling off the precipice just outside. She doubled over, panting heavily, safe for now. Her cock wiggled between her thighs, seemingly uninhibited by Jill's exhaustion. Her plight was not yet over, but the worst of it seemed to have passed. Once she regained her stamina, Jill was sure to seek help with regard to her condition. As long as she could avoid the worker drones that was surely still about, then salvation would once again be in her grasp.
