The abandoned hole.

You feel drawn towards this booth. It is dark and foreboding, but smells weirdly sweet. You step in, and close the door behind you. You drop your pants, your cock already hardening from the tension. With a moment of hesitation, you slowly stick your cock into the hole.

Initially you feel nothing but cold air on your cock. You almost pull out when you suddenly feel something coil tight around your cock and preventing you from doing so. It writhes and tickles around your cock like 100 tiny feet. Suddenly you feel something press against your urethra. You slam on the wall to try and get it to stop but it's too late. You feel it push its way inside and it starts to slither down the inside of your cock. You feel its tiny legs tickling the inside of your urethra, the sensation overwhelming. It's like a centipede is crawling down it!

Your cock feels full as it continues to stuff itself inside it. Feelings of disgust and pleasure intermingle as it continues its path, finally reaching your prostate. You feel it coil itself into a ball inside your prostate and writhe madly. You are brought to orgasm in seconds, feeling the cum squirt its way around the invader. You remain on the edge of orgasm even after you come down. You finally feel you can pull yourself free from the hole and do so. Aside from a stretch urethra, your cock looks like normal. Your prostate tells a different story though.

You feel feel it writhe inside you madly. The sensation is violating yet orgasmic. Suddenly you feel your innards begin to shudder and writhe. You fall to your knees and clasp your hands to your face in blissful agony. You see your fingertips harden and blacken, turning into claws. You feel your skin harden and turn into carapace plates. Your cock writhes and you begin furiously jerking it. You roar as you shoot another thick rope of cum onto the wall. You can see the cum squirm with hundreds of little white worms. Your cock has turned a latex black and grown a knot, ready and raring to spread this infection.

You slam out of the booth and charge down the tunnel off pure instinct. You can smell a victim in the dungeon. You climb up the wall and onto the ceiling, sneaking around in search of your prey. You eventually find them near the chute you fell in through. They look just as confused and unprepared you felt upon entering. Perfect.

You stick your back to the ceiling way up above her and begin to stroke yourself. You drop a glob of thick precum onto her face and watch her reel in shock. The shock is short-lived, giving way to pure arousal. She drops to the floor in heat, your precum a potent cocktail of pheromones. She's **** to rip her pants off even before you drop down. She couldn't care less about your monstrous appearance upon seeing the monster between your legs. She spreads her legs wide and lets you rip her panties off. Her red puffy pussy drips like a faucet, ready for you to plug the leak.

Despite your size, your smooth cock slides in with little resistance. Her pussy clenches and throbs, **** for relief against the heat inflaming them. You piston your hips with a mechanical precision, a physical memory engraved into your DNA by the parasite. She wraps her arms around you and holds on for dear life. She cries out in ecstasy and relief. You feel the both of you nearing orgasm, the base of your cock swelling in preparation. Right as she hits hers, you press your knot inside her pussy with gusto. Her eyes flutter as you fill her womb with tainted cum. You see fear register in her mind for an instant as she feels the parasites wriggling inside her. She tries to push off you but is interrupted by her body beginning to shift and change.

Her skin begins to turn dark black and smooth like latex. Multiple areas harden into chitinous plating all over her body. Her boobs remain, now vestigial, but look as if made from latex. Her jaw splits into mandibles, her fingers into claws like yours. Within moments she has become a bug person like you. You can feel her thoughts intermingle with yours as you become a hive mind if two. You pull free from her pussy with a loud pop, white slime and worms dripping out. You and your mate run into the labyrinth to wait for more victims to infect. For more to join the hive mind.
