Retrieving a downed probe on a hostile planet?

The planet of Odin-6 was a nasty place, a mass of bubbling mud and slim, inhabited by strange hostile life forms. Unfortunately, it was where Joanna and her team were going. A scientifically vital robot probe had crash-landed there and it was the Angels job to go get it.

Two shuttles full of Angels descended towards the unappetising ball of whitish mud, heading for what orbital recon said was a relatively stable point to land on. Joanna sat in the rear troop seat of her shuttle, checking her weapon one last time before they landed.

The two shuttles landed with a pair of jolts and the ramps fell. Joanna jumped out along with the rest, her long legs sinking waist deep in thick, slimy white mud “eeww!” Joanna tried to keep her gun clear of it “yuck!”

Kelly Arnold, a ditzy blond private who was Joanna’s battle partner jumped free beside her, yelping as her slightly shorter form sunk further. “help! I’m stuck!” the angel called.

The angels floundered around, attempting to get out of the thick substance without getting it inside their weapons, Joanna was just worming her way up when she felt something touch the inside of her leg and froze “I think we’re alone here…”

There was a sudden slurping noise and Kelly was sucked down into the mud up to her tits. She yelped and then suddenly moaned “Ooh! It got through my suit!” the private’s heart beat raced as her body began to bounce up and down in the mud, Joanna not sure what she was seeing for a moment, then she realised, something had plunged through Kelly’s armour and rammed into her sex, she was seeing her friend bounce around as she was fucked.

There was a grinding sound Kelly’s power armour was torn open from the in side by several tentacles, leaving the blond collapsed in the mud, naked and exposed as arm thick alien organs rammed into her. Other Angels were sucked down, some firing into the alien invisible bellow the mud, some trying to scramble back aboard the shuttles. Tentacles pushed up into them, pushing through power armour as if it wasn’t their and into the angel’s most sensitive parts, other limbs tearing their armour away to leave them naked and helpless in the cloying alien soil.

Joanna felt something grab her ankle and pull, yanking her deeper into the mud.
