Commander Jillian Vibe groggily came back to consciousness in the dark, humid cave. She was held fast on her knees, her legs from the knees to her feet solid against the ground, and her arms held behind her like she was in handcuffs. Her teal form fitting uniform was torn in numerous locations: one breast, her stomach and hips exposed to the dank air. She pulled and struggled, but her bindings only gave the smallest amount, then wiggled and squirmed like they were hands or tentacles aware to her movements and dedicated to the task of holding her still.
She looked toward and out the entrance of the cave and saw their small space craft where they'd landed it. The perfect small flying saucers gleaming metal with bubble canopies. She and Sarah were there alone to explore the planet. Their ship, the SOLSTICE, wouldn't be missed until they were overdue, which would be hours because this planet was supposed to be uninhabited.
She looked around the cave at the green roots and tentacles that covered the wall like a spiderweb of tree roots, wiggling and moving ever so slightly to give a sense motion.
On the cave floor, only a few feet in front of her, lay her ray pistol and her space suit's helmet, that looked like an upside-down fishbowl shrouding her head when she wore it. She struggled again, but it was hopeless.
Her crewmate, Lieutenant Sarah Jacobs, her uniform torn and more flesh than cloth exposed as she whimpered and struggled against the green, living vines.
"Sarah! Sarah!" Jillian yelled in a whisper.
Sarah looked tired from struggling, but she didn't stop.
Jillian noticed in terror that a lone tentacle with what looked like a large suction cup on the end was slithering its way up Sarah's naked body toward her face.
Jillian tried to scream and warn Sarah, but her voice wouldn't find its way out of her throat.
She watched as the tentacle with the suction cup, big enough to cover a face, slithered between Sarah's large breasts and around her neck to holding Sarah's squirming head still. Then, as slowly and as gracefully as a baby being rocked to sleep, the creature's suction cup covered Sarah's nose and mouth.
Sarah's eyes grew wide as she struggled to move her face from the tentacle, which pulsed like it was inflating and deflating with each breath Sarah made. Her eyes, once full of shock and panic, began to soften. Her eye lids became heavy, and her whimpers of struggle became moans of something else. Her heavy and half closed eyes looked into nothingness as she stopped struggling all together. She began breathing more and more of whatever the tentacle provided her.
Jillian watched as her friend and fellow officer succumbed to the creatures' advances. One after another, tentacle after thick tentacle wiggled along her body, caressing her thighs, and spreading her legs until one appendage, thick and slick with slime, slid between her legs and impaled her vagina in one slick motion.
Sarah moaned in pleasure and writhed in bliss, forcefully sucking more and more of whatever the thing on her face was forcing into her body; bobbing her head like she was pushing her face more and more into the tentacle with each thrust the tentacle in her pussy gave her.
Her orgasm came forcefully, rolling her eyes back into her head and causing her body to spasm as thick gobs of cum leaked out of the tight fit of the tentacle and her pussy. Then, like her spirit was giving over to the will of the creature, her eyes fluttered, lost focus on anything, then closed and her body went limp.
