Grey Goo

The peculiar droplet of goop seems to be a greyish colour, although exactly what shade of grey is difficult to tell due to how dim the room is, even with the light over your head. The hairs at the back of your neck stand on end as the grey drop suddenly twitches, as if alive. Loud slurping assaults your ears as a steady stream of grey slime drips from the ceiling, slowly trickling down to your nude body and pilling onto your stomach, shivering at its cool touch.

You then ponder to yourself, “What in the world is this stuff?” As if on cue, the grey mass suddenly crawls up your body, heading straight for your face. Chills go down your spine as the strange goop flows up your body. A surprised grunt escapes your lips as the goop attaches itself to your face with a wet slurp, sounding like a very messy kiss. With your limbs bound by an odd wet substance, you're unable to pull the grey mass off. Choosing your next best option, you scream for help. Yet as you open your mouth the goop sees it as an invitation, flowing inside, triggering a futile gag reflex, and a storm of mental profanities.

Unaware of what is happening to the rest of your body, your mind starts to become hazy. Almost not caring anymore, your cloudy eyes widen as you realize what the goo is doing. Your mind flashes back to the squeaky latex purple wolf that had melted onto the man earlier, transforming him into a large blue catman. The same catman that knocked you out.

The haze lifted from your mind, your struggling begins once again, reinvigorated by the unwillingness to become some sexy muscled animalistic freak made out of rubber. Yet as you're still distracted by the latex rushing down your throat, all movement ceases as you feel something prod at your hole. Something large. With little time to react or even brace yourself, the dick made out of latex practically impales you, eliciting a muffled cry of mixed pain and pleasure. You grimace as the tendril of goo continues to penetrate you, going deep inside you. The penetration slowly vanishes until it is replaced by an odd tugging as if someone was pulling on your tailbone.

Suddenly before you know it the latex binding your wrists and ankles to the table snap off, causing you to drop to your knees onto the cold stone floor. Latex continues to drip from the ceiling, coating your backside. Your eyes snap open, vision restored and more clearer than you ever remember. Desperately touching your face, a beastly gasp escapes your mouth, which are now jaws lined with sharp teeth that could tear prey to shreds.

As you feel the latex begin to change you, your insides rearrange and change. You begin to take notice of your physical changes. You first look at your back noticing the huge shark tail you have and noticing the dorsal fin sticking out of your back. While examining your back you realize your hands and feet are now webbed, and a couple sizes larger than you remember, the webbing between your toes almost resembling diving flippers. You also take notice of the smaller fins at the back of your forearms and calves. Your attention is suddenly diverted as your eyes make their way down to your package. While admiring it you discover that your package has grown a few inches.

Before you get enough time to really look over your cock, more squelching comes from the ceiling. Looking up, your eyes widen as a drippy latex tendril falls from above, landing at your webbed feet. Curiosity piqued, you prod the latex tentacle with your foot, recoiling in surprise as it suddenly latches onto your foot, crawls up your leg, coils around your dick, and plunges right into your urethra. Unable to even register anything besides intense pleasure, you find yourself on your bottom clutching your balls as they gurgle and growl, sounding more like an upset stomach.

You start to feel a mix between discomfort and pleasure as your balls begin to grow and contort, your shaft slowly lengthening along with their growth. The growth ends as your balls gurgle one last time. Panting in pleasure, you lustfully clutch your balls, grinning as you realize they had grown to a size big enough for you to hold one testicle in your hand. Sliding another hand down your new length, your grin widens as you also acknowledge that your cock has grown to a thick spear of manliness, totalling at 9 inches.

Your jaws widen into a lustful grin, before opening in pure animalistic lust, allowing drool to drip down your lower jaw. Fondling your balls with one hand, you take your other hand and begin to sensually stroke, slowly increasing in speed. An intense pressure builds up in your sack, so much so that it almost seems as if your balls inflate again. Contorting one last time, your body tenses.

Time seems to halt as all feeling stops.

Then a loud primal roar escapes your jaws, your webbed toes curling in pure bliss as your balls groan and gurgle, your spear shaking as a torrent of grey latex erupts, firing into the ceiling where the grey goo originally came from. The floor is completely flooded in grey.

Panting heavily, you fall to your wide muscled back, your large schlong flopping over your onto your leg. After a few deep breaths, you relish in the fact that you can still think. Slowly rising to your feet, you chuckle as you notice the entire floor is drenched in grey goo, most of it from your shaft. Massaging it one last time, you gaze up and grin at the sight of a door present behind the table you'd been bound to.

It was time for ****.

And to find out what the hell was going on inside this mansion.

Both were acceptable.
