I watched with boiling blood, hidden atop my perch, as the fetid monster stood with Manda firmly in its grasp as it proceeded to molest her.
The creature was man sized yet tall at six feet seven inches with a muscular build!
Wearing only a dirty brown loin cloth around its genitals it had ugly dark olive green skin, a goblin like face with pointed like ears, and a mess of short straight smooth hair atop its head!
With one muscular arm wrapped around her torso it used the hand on the same arm to grope, pull, and squeeze at one of my poor, beloved sister's tight sizeable boobies through her white buttoned down dress shirt!
Meanwhile the monstrous being's other hand freely diddled between my sister's legs, slowly moving his large index and middle fingers in a circular motion DIRECTLY INSIDE my poor little Sister's deliciously small warm tight smooth soft fleshy lush bald pussy making soft yet very audible squishing sounds that echoed through the interdimensional landscape!
SQUISH, PLISH, GUSH, SQUELCH, SLURP, SPLISH, SQUISH, PLISH, GUSH!
Poor Manda seemed paralyzed in the creature's grasp as her eyes were closed shut and teeth softly clenched while her head hung to the side.
Her arms were hugged to her sides where the creature had a grip on her.
It was obvious whatever pants, skirt and/or underwear were missing from my beautiful Sister's legs as the creature had obviously torn them off leaving my embattled Sister's lower half completely butt naked if you'll excuse the expression!
I had cursed myself for the current situation my poor Sister was in for I should've seen it coming a mile away and should've been on my guard but had let myself be taken in the moment.
You see Manda and I were descendants of warriors tasked with hunting and destroying interdimensional beings known as the Shikima that made frequent trips to Earth to prey on young suspecting victims and for years Manda and I had trained to hunt these evil beings.
Now aged eighteen and nineteen we had completed our training and were now on our first hunt, Manda dressed in a white button down shirt and red panties and I in a red tank top and white panties.
But then Manda began to act strange and began to masturbate herself, pulling down her red panties to her thighs so that her small smooth soft virginal tight moist pussy could be seen before she began to rhythmically move her middle and ring fingers up and down inside of her tiny tight smooth soft fleshy lush moist throbbing quivering pussy while simultaneously lifting up her shirt and groping one of her large round full plump smooth tight boobies in a circular motion!
Squish, Plish, Squish, Plish, Squish, Plish, Squish, Plish, Squish, Plish, Squish, Plish!
"What's happening, why do I feel like this all of a sudden?" Manda had panted whilst continuing to masturbate, all while I watched completely transfixed and in disbelief at my Sister's behavior!
"I need someone...I NEED SOMEONE!" Manda had then wailed in an unexpected escalation of events, before she looked at me, eyes glazed with lust before she removed her fingers from between her sodden logs and began to walk towards me on shaky legs as if she were a sex crazed zombie!
Now seeing my sister naked or in sexual situations was nothing new, in fact, it was part of our training process, BUT to be sexually aroused during a time where we were supposed to be hunting interdimensional beings that wanted to rape and possibly KILL us was somewhat detrimental to our mission, nevertheless here was my younger sister coming onto me!
And then just like that, I had seen the demon behind her, tall and muscular as it wrapped its meaty arms around her frail delicate torso.
It had given me a sneering look before taking off into the night sky where I immediately gave chase!
And now here I was, observing whatever evil, horrific perversion awaited my poor little sister! I did not have to wait long!
"Kyomara-san, I have brought Manda Panda to you!" Boasted the creature that continued to molest my sister!
"See? Her body is so sexually aroused that her womanhood flows uncontrollably with the love juice!" Continued the creature in a musing voice!
I could clearly see the thing's head tilt slightly to the side as it enjoyed the undoubtedly tight, quivering fleshy lush warm moist throbbing of my Sister's barely legal cunt!
Poor little Manda could only hang her head to the side in resignation as she twitched at feeling her sex be violated however.
Yet what this monster was doing to my sister was NOTHING compared to what I would witness next for within the cave in front of the being holding my poor little Sister, something stirred.
"Ah, the crack of a skilled woman is tasty indeed." Mused a blood curdling voice and without further ado the monstrosity stepped forward!
At twenty five feet tall the thing was a grotesque olive green and covered in what looked like slimy armored skin. Muscular legs held up it's great trunk that looked like a spiked turtle shell with a split in the center of it ended in massive three toed talons!
Between its muscular legs was a massive churning green scrotum as well as a receded green penis that looked like a rolled up sleeping bag.
Its arms were also muscular ending in five clawed talons!
A multitude of thick writhing green phallic shaped tentacles, all various sizes, and some ending with eyes on the end of them adhered to the monster's back!
Yet despite all of this, probably the most hideous thing about the monster was its crocodile like visage with two rows of sharp teeth, one on the top, one on the bottom, with its right eye being a fiery gold and yet its other eye being a revolting little orange face that I could clearly see was excited to see my little sister's violation, made all the more clearer as the vile thing actually spoke for the monster!
"Damned female, you will be taken as you never have before!" Declared the monster!
It was at this point that poor little Amanda for better or probably worse woke up from her trance and saw the monstrosity before her and I could clearly see her eyes wide with impenetrable fear!
Meanwhile between her legs, the evil monstrous being that held her had begun to thrust his fingers up and down inside that wonderfully small tight smooth soft fleshy lush pussy of hers, causing Manda's love juices to slide down his fingertips and making that oh so tantalizing wet squishing sound over and over again!
"Now see!" The monster who I now knew as Kyomara said teasingly as he undulated two of his seeing eye tentacles in front of Manda!
