(Inspired by Seduced On The Bridge by Little White Mouse)

Tandy and Sue were screaming...and running...actually more like slipping and sliding; an unsurprising situation, considering: two oiled up sweaty, panicky young women trying to outrun, what could best be described as, "Giant shrimp!" (Tandy's words), on a hot, humid spaceship bridge, over a moisture and slime slick floor.
These factors ensured the women were not upright for long. Tandy and Sue soon found themselves on their backs, tripped and slipped into their supine positions by the creatures. The crustazoids were moderately clever: when the girls fell, the crustazoids had positioned themselves beneath them, so that the girls landed on a cushion of alien shrimp.
The crustazoids then repositioned the girls next to each other, at opposite ends. Sue's head was at Tandy's feet and vice versa. The crustazoids formed a bed underneath the girls and held them captive with their appendages. The girls' legs were spread so Tandy and Sue had a good view of each other's pussies.
Now, a brief description of the crustazoids: yes, they look like shrimp...with a touch of horseshoe crab...plus some softshell turtle thrown in. Their color is a dull grayish brown with green blotches. The males look more like the aforementioned horseshoe crabs. They have four appendages on the upper end, and two smaller legs near the bottom. Three large tailfins are attached to the body. The males are roughly the size of a basset hound.
The females are larger; many are the size of humans. They have two large sinuous appendages on their upper torsos. Their lower torsos hold the fertilized eggs; when full they look like bloated sacs. Males and females tend to have a glossy appearance due to slimy excretions from hidden pores.
The girls were still screaming when the female crustazoid appeared. Tandy's pussy was facing it, so that's where it went. It used its tiny legs, and assistance from the males, to propel its bulk onto Tandy's body.
The crustazoids worked their soporific venom into the girl's bodies, through light scratches on the skin. The venom was potent and easily absorbed. A tiny amount was enough to quiet the girls and slow their movements; minimizing their struggles while they were positioned.
Sue watched in dulled horror as a "shrimp" crawled onto her torso and used its legs to spread hers. Tandy, on the other hand, gazed fearfully at the big "shrimp" as it slithered over her body, its bulging sac positioned between her legs, the chitinous face placed just under her boobs. The sinuous ropes opened her legs wider.
"Tandy! What are these things doing?!" Sue cried.
"I don't know Sue. I can barely move. It's like my body's asleep or something."
"I feel the same way. Can you see what that thing's doing? I can't raise my head."
Tandy slowly turned her head. Sue's pussy lips stood out pink and moist. "Sue, I think it's going for your pussy." The creature revealed two tiny 'fingers' on the sides of its mouth. They went to each side of Sue's lips and spread them, opening her vulva wide and pink.
"Ohhh, it's doing something! I can feel it!" Sue cried.
"It's spreading your lips," Tandy replied; she had a clear view of her friend's clit.
Tandy watched as the creature opened a slit-like mouth. Out of that mouth came several serpentine tongues. They slithered into the moist cave; one wrapped around Sue's clit, which blushed and swelled, the others delved further into the tunnel, already flooding with moisture.
"Oh!" Sue gasped. White heat bloomed in her nethers. The creature moved, lightly, back and forth, issuing faint slurping sounds.
"Oh God! What's happening?! I'm feeling wet!"
"It's sucking you, Sue! The thing's sucking your clit! It's eating you out!" Tandy looked in wonder. "What kind of creature is this?!"
Sue started to breathe heavily, with quiet hitches. The creature rode up and down her torso. It planted its chitinous face onto her dripping wet pussy. The slurping sounds increased, albeit muffled.
"Tandy, I think I'm going to cum," Sue said softly.
"Fight it Sue! What are people going to think?"
"I don't think I can. It...mmmm!...it feels good, Tandy. I can't explain it but I'm feeling warm and wet and....mmmm!....I'm cumming...ooooh!....it's hap---mmmm!" she purred.
Tandy knew Sue was a quiet fuck. She remembered the hotel room they shared in New Orleans. They fucked their Mardi Gras dates on a king sized bed. Sue came with the same quiet hums and purrs she made now.
Sue's oil, sweat, and slime slick legs moved up and down. Her right hand worked its way underneath the creature, as if she wanted to join the cum milking. She moved her left hand to her breasts and began to knead and play.
