The amorphous sea creature slithered along the cities' inner workings.  It's formless structure stretched along the pipes and ducts in search for more of the irresistible pheromones.  The ooze had tripled it's size since discovering the young girls secretions.  It also increased the ability to change it's viscosity from one that was solid, to a free form of liquid water.  The creature could at will, flow thru these underwater tunnels, and then take hold of a beam and switch it's trajectory at once.  The blob felt a powerful urge overtake it, and it darted towards these wonderful sensations.  Unable to resist, it sped onward with the desire to taste the elixir for life, human female pussy juice.

Amanda, Jackie, Valerie, and May entered the locker room after tennis practice.  Their young, hard bodies glistening with sweat.  They were all 17 years of age, and beautiful in different ways.  May's short golden hair, accented a cute face.  Her green innocent eyes spoke volumes to her peers.  Her button nose, dimpled cheeks, and an alluring smile went along way with
her bubbly attitude and zest for life.  Her figure was small, trim, and dainty.

Valerie's rough good looks were chiseled like a marble statue.  She's the biggest and strongest of the girls.  She liked to work out, and it showed.  Muscled features highlighted her athletic pose.  Her stomach flared out with a defined six-pack, and her ass and legs were tight and sexy.  The tanned brunette also had a large chest to envy, a feature men couldn't resist to
marvel at.

The sexpot of the group fell to Amanda.  The modelesque beauty had the looks to kill.  The way she walked, the way she talked, and the outfits she wore, could make a dying man erect.  From her long blonde hair to her shoe size 5 feet, there wasn't a curve out of place.  A tease she was, and a tease she would always be.  Amanda knew how to drive men crazy, with her slit
skirts, and cutoff halter tops.  The tennis outfit drew loud whistles every time she wore it to school, instead of just practice.

Jackie, had the smart looks.  Dark hair with glasses, always looked away when confronted.  Her shy disposition, couldn't hide the beauty that lay below the drab clothes.  She had the most shapely legs of the group.  Her legs made this Korean girl a very hot attraction to the boys during practice.  She felt their gazes, but never reciprocated them.  Her demeanor, made her an introvert, and she kept to herself.  Although, she admired her good looks in the mirror many a time.

The girls talked about their individual accomplishments as they stripped off their tennis outfits and headed into the showers.  Each of the girls with separate shower heads, but in one big room.  As the girls gently applied soap to their young sweaty bodies, the sea beast slithered onto Valerie's muscular torso.  All at once she screamed, alerting the other girls to her trauma.
"Get it off of me," Valerie yelled.  She felt it tease her chest and pussy, and suddenly became aroused at the things manipulations.

"What is it?"  May inquired.  She took a step forward and the thing lunged an appendage at her ankles and she fell to the shower floor.  The ooze quickly covered her lower body and dragged her towards a helpless Valerie.  Both Amanda and Jackie tried to run out of the shower, but only managed to fall prey to the monster's powerful grasp.  The ooze climbed along their bodies and pressed against their womanhood.

"Help us!"  Amanda bellowed.

"It's going inside of me," Valerie stated.  "It's making me feel, ahh...so good.  Make it stop, ohhhh..."

"No," Jackie screamed.  "I don't like this...get off of me, please!"

"What's happening to us?"  Amanda questioned.

"I don't know," May answered, "but it wants to touch our sensitive spots.  It feels real good, but we have to ahh...we have to try to resist, ahh!  We have got to try, ohhhh...it feels so good.  I, we have got to get out of here, mmm...before it's too late."

"I don't, mmm...think, ahhhh..."  Jackie gasped uncontrollably.  Gyrating her hips along the shower floor.

"It's touching me everywhere," Amanda said.  "I can't resist, it's sooo nice.  My body feels alive, mmm...I don't have any will power to stop my body from, ugh, reacting to this strange goo, ahhhhhhh!  It's twisting my nipples, mmmm, oh, it's fucking my pussy, ugh, mmmm..."

"Amanda," May called, "you ohhhh...have got mmmm, it's so great.  Amanda listen to me.  Ohhh, I need, oh please not there, ohhh, stop, please I can't take ahhhh, help me please, help me, mmm..."

"Girls," Valerie cried, "I can't break free, ohhh, I tried so hard, ohhh...so hard, yes!  That's it!  Ohhh, right there, ohhh, it's on my clit, ahhh!  I can't control my, ahhh, myself anymore.  I feel it tickling my every, ahhh, mmm...oh, tickling my pussy inside and out, mmm...more, ahhh, more!"

"Ughhh, please!"  May continued.  "It's all over me.  I can't ahhh...break loose, mmmm.  It's thrusting into me, ooooh, in and out, in and out.  My tits are so, mmm, so sensitive.  I don't want this, ahhhh, but it feels so damn good, mmm, some...body, mmm help, ughhh..."

The girls were writhing all over the ground as the liquid based monster fed off their wanton desires.  They tried in vain to escape, but the excitement that was overtaking them, was too much for their young minds.  Valerie bucked in rhythm to the powerful thrusts against her hard body.  Her large legs spread eagerly in an attempt to feel more of the sexual arousal
she craved.  The thing moved within her and drove deep inside of her, and then back out, over and over again.  A steady pace of pussy attacks made the girl cry aloud in orgasm.  The best she ever had.  No boy ever made her feel like this.  Her body gave in totally to the monster, and she became one with the creature.

Jackie, the sole virgin of the group almost admittedly gave into the new manipulations her body experienced.  She only had fingered her pussy in front of a mirror a few times, and never explored these desires to the fullest.  Always stopping before she got too overwhelmed by her desires.  Now, as this blob, touched her, excited her, and caressed her most sensitive areas, she
couldn't help but to give in.  Tired from the long tennis practice, Jackie's resistance was low.  The thing made her feel warm all over, and the thrills that arose inside her womb paralyzed her movements.  Escape didn't matter, she wanted to succumb to her eroticism.  Slithering around her, the ooze explored her pussy, and tickled her clit until it popped out full and proud.  She ground her body against the probing and moaned continuously as the pressure grew inside of her.  After her cherry gave way, she felt no pain, only pleasure as the creature stabbed her repeatedly deep inside her pussy.  The young girl screamed as the first orgasmic wave sent her to new boundaries yet unexplored.  The sea monster thrust itself against Jackie's fuck hole, and teased her tits and clit with rapid strokes.  Another orgasm sent the girl into a quivering mass of gooseflesh and moans.

Amanda tried her best to focus on ignoring the attack of her body.  If she couldn't escape this gelatinous ooze, she certainly would not let it take her mind with a few caresses.  She made herself numb to the creatures maneuverings, and thought about other things.  Concentrating not on the loving the ooze gave to her, but on home, school, her family or anything else.  Even as the thing moved along her most tender areas, she fought the urge to submit.  Denying the impulses overtaking her mind.  Slowly, almost unnoticeable to Amanda, she started to spread her legs apart.  A moan escaped her lips.  She tried in vain to resist.

The thing had her, and she couldn't find it in her to block the sensations out anymore.  It was like tiny mouths all over her body.  Amanda's tits were swollen and erect with guilt stricken desire.  She wanted none of this, but it felt so good.  Her pussy quivered as the blob, teased the young girl's clit.  She let out a scream of pleasure as the thing entered her love tunnel.  She came despite herself, and loved every minute of the ecstasy.  The movements of the ooze were met in rhythm with Amanda's hips.  Her body took over, as her mind let go.  There was no trace of fight in this 17 year old any more.  Pushing her pelvis upwards, she allowed the creature to push deep inside of her pussy.  Bucking herself faster and faster, she couldn't get
enough of the pleasurable thrills circling her body.  She came over and over again, and any traces of resistance were a lost memory at this point.  She became a fuck machine as her body thrust with more speed than she ever thought herself capable of.  Driving her body crazy with an unexplainable desire, the blob sucked the teenager of her juices, and only wanted more.

Clara Dulles, the tennis teacher, heard a scream as she entered the locker area.  She turned the corner of the showers and she was stunned by the hideous scene in front of her.  A tendril snaked out towards her, but she reacted too fast.  She ran immediately for help.  She screamed for anyone left in the school.  When two maintenance personnel appeared she urged them
to go to the gym locker room, whilst she called the authorities for assistance.

When they got to the shower the fours girls were intertwined in a mass of flesh and jelly like substance.  Jackie and Valerie humped their pussies into each other whilst Amanda spooned May in an erotic doggie style pose.  All four girls ground themselves into each other with blinding speed.  Moaning as loud as any of the two onlookers had ever heard anyone scream from sex.  The two men were transfixed by the glistening young girls' bodies.  They knew they had to help, but all they wanted to do was watch this display.  It caused unwanted stirrings within their pants, and they unknowingly licked the lips in response.  Mel the older of the two took a step forward and noticed that the thing was between the two sets of girls.  The blob had made a phallic shape and thrust itself between the girls legs.  Allowing the girls to push it inside their pussies with every drive of their bodies.  Around their waist and chest the monster harnessed their bodies into this interlocking love tryst.

Mel took another step forward followed by Anton who took out his box cutter for precaution.  Mel kicked a piece of the goo slightly with the tip of his foot, and didn't illicit any action.  As he turned and shrugged his shoulders at Anton the ooze quickly surrounded the men with tendrils blocking their exit.  Anton sliced at one such tendril and it went right through like water causing him to fall off balance to the floor.  The ooze made it's way up the cuffs of his pants splitting them as it quickly stripped the custodial worker down to his boxers where his sedated manhood lay dormant in fear.  When Mel tried to leave, the blob worked his clothes into shredded linen within a blink of an eye.  Both men's cocks were engorged just as fast when the creature massaged itself along the head and shaft of their purple staffs.  They then were gently guided to the set of girls.

Amanda was dimly aware of the men's presence until she felt the protrusion against her ass.  Too excited to care as she rammed her pussy repeatedly against May's Ass cheeks.  Humping her doggie style to get more of the ravenous pleasure that the monster demanded them to get.  Fruitless in her escapes, she just lived in the satisfaction the liquid giant gave her.  All
she wanted was more.  More body shaking orgasms that took her breathe away.  More of the delights of the erotic senses.  Taking her to places she would never forget again as long as she lived.  Pounding relentlessly against May's helpless ass, which in turn struck back in earnest.  May cried out loud as another and another cum session shook her body from the fuck fest her tennis partner gave her.

Mel and Anton like guided missiles striking their targets, entered the rears of Amanda and Valerie from behind, respectively.  A vice grip around each of the man's testicles prevented the men from cumming, keeping their desires at bay for the moment.  When they entered the young girls it was if a dream had come true.  Anton gripped Valerie's large muscular ass with his
hands for support and began to shimmy his pipe into the corridors of heaven.  He was led by the ooze, but soon fell into his own rhythm and took over the ramming.  Mel did the same with Amanda's tight butt, needing only to follow the girls own movements.

Valerie groaned in pain and pleasure as her virgin rear became exposed for the first time.  The blob around the maintenance worker's cock made it easier to accept as it slid in and out with no undo friction.  She was overcome by the magnitude of her fullness in her backside.  It made her excited even more if that was possible.  She came long and hard, as the creature between Jackie and herself and the penis in her ass knocked her around like a ping pong ball.  In and out, back and forth.  Her mind knowing this was wrong but so helpless to stop it.  Not for the life of her wanting this to end.

Amanda grunted at the unwanted intruder, but immediately came as soon as Mel struck home.  Her small waist wiggled as the man held on for a long hard ride into her dark fuck tunnel.  He barely used any force against the slim teenager.  His cock gripped her well and produced a suction popping sound with every thrust.  They both felt the creature along his shaft make the
lunging easier and more erotic.  He felt like he would have cum already if it wasn't for the creature holding him in check.  So he danced along, slapping his groin against Amanda's ass over and over again.  Not wanting to stop, until the desire within him was released.  He looked down at the other girl grunting and thrusting her ass upwards to their partners' pussy.  Her green eyes glazed over, her short blonde hair, face and her smooth shoulders dripping in sweat, as she looked up at him.  Those eyes although distant, filled Mel with deep desire.  He fucked Amanda harder, as if his new urgency would be felt through May as well.  Both girls came again, but the bucking didn't cease, so Mel rode on and on and on...

By the time Carla arrived with the police, the mass of sweaty bodies was minus the mysterious blob.  The men had a lot of explaining to do, the girls had a lot of resting to do, and the hunt for the sex monster was on.  Although, the large sea creature, now the size of a two car garage, was on it's way to the heavy trafficked Western California University Olympic size swimming pool.  Presently, the site of the WCU Women's Water Polo Finals against Bolaura Polytech.  A contest that would not soon be forgotten.

The End.
