The shower head!

You grab the shower head and kick the faucet to the maximum setting. The Ultra-Turbo Deluge 3000 is a top modern shower-head with all the trimmings. At this kind of pressure it should slice right through a silly blob like a hot knife through butter! Or it would if anything had happened. There are a few blorps and bangs coming from the pipes, but no water. Disappointed you turn the head towards you to see if anything is plugging it.

Ah, slapstick. What could be better? The water hits you right in the face and you drop the showerhead in surprise. The hose starts flailing about, spraying water everywhere but accomplishing nothing. You are still trying to wipe moist bath-salt gunk out of your eyes when the blob descends upon you.

The thing fills the entire bathtub with its bulk, smothering you. Only your legs hanging over the edge of the tub remain free, and your wildly flailing arms which poke through the surface. Underneath the blob you try to hold your breath despite the tickling sensation of a myriad of mouths kissing you all over your body as the thing is licking, sucking and slurping the salt off of you.

Eventually the bathsalt is all gone and it starts to look for more. You recall with terror your glowing bottle of mouthwash just before a probing tentacle forces its way into your mouth and down your throat. Panic sets in and you barely notice the other tentacles invading your ass and pussy, searching for delicious salt. They all start to move in and out at a steady pace as if to scour your insides clean.

To your great relief the main bulk of the blob begins to crawl up along the wall, dragging you along with it, upside down. You take a deep breath through your nose. You try to grab the tentacle in your mouth and pull it out but it's slick like soap or bathoils and you can't get a firm grip. Sensing your intent the blob once again grabs hold of your arms with a new pair of pseudopods.

You kick about with your legs which are still free but this too is only a brief lapse of tentacle judgement. Soon your legs are held apart by strong ropelike membranes, giving the thing unrestricted access to your insides. It has now realized that your vaginal fluids taste just as nice as the bathsalt and is trying its best to make you produce more, and more.

Tiny tentacle tongues tickle your clit and a series of coils squeeze your breasts and tease your nipples rhythmically, just the way you had hoped a human lover would do one day. You can't help but cry but if its from being robbed of your dignity by a mindless beast, or if its from the series of orgasms it brings you, you can't tell for sure. In a final insult the beast greedily licks up your tears in a parody of passionate kisses, lapping at your face with a sucking tube.

The main bulk of the blob is swelling almost visibly and you are wondering if there is some kind of chemical reaction going on inside to make it bloat like that. Then you realize that its digestive system must be working overload from all the bathsalt it has digested. It looks almost ready to blow.

Suddenly the tentacle in your mouth bulges up with internal pressure, pulls out and sprays your face with a hot, sticky viscous fluid, not entirely unlike human semen but composed of the chemicals that the creature can't digest. It tastes strangely sweet and is also glowing in the monster's aura. Once it finishes the tentacle hangs limp and spent for a moment before it pulls back into the bulk of the beast.

The other two tentacles that are still in the process of violating you concurrently expand like fire hoses, making you gasp with pain and surprise as they stretch your holes to the limit. Then they explode, filling you with more sticky "cum". When the tentacles slowly pull out they are still shooting the liquid, squirting thick strings all over your trembling body.

Having finished with you the blob slowly retreats to its original hiding place down the bathtub drain, where you always knew a monster was hiding when you were a kid. You wish you hadn't been proven right quite so violently. Oozing cum out of every orifice you finally manage to grab the still spraying showerhead and put it to use in a vain attempt to get clean.

That could have gone better but at least you survived. You hope nobody else in the house heard what was going on but since they aren't here checking up on you, they are probably sound asleep. Having washed the disgusting creature's ejaculate off you return to bed, wondering what the rest of the night might have in store.
