Alone amidst an ocean of vines

Time means nothing in your comatose state, oblivious to even the most basic limits of the world around you. Instead, you find yourself home, among family and friends, as though the mission to station Sigma had never transpired. And for awhile, it was good. But like all good things, it ends far to soon.

A sudden cramp, like something thrashing angrily deep in your innermost core. The pain forces you out of your blissful slumber, and slowly the memories come flowing back like high tide. Everything aches, whatever those things were, they really put you through the wringer. Speaking of which, where were they?

You try to move, but instead find your limbs remain bound, each pulled in a different direction by tightly clinging vines. Eyelids still heavy from exhaustion, you survey your current predicament.

Anything that was left of your suit is now gone, leaving you totally bare to the living jungle around you. But that's not why you croak out a defeated scream. Your stomach now swells before you, even larger than when you were seeded.

So they did breed you. The question remains, what are they?

Rather than an answer, you receive another sharp twinge, the seedlings (If they can even be called that) are moving again, much more insistently than before. An agonizing cry tears from your throat, eyes clenching tightly shut, as if that would stop the grim spectacle.

As if on queue, something long and thick slithers down to rub against your cheeks, before pushing it's way past your plush lips, muffling the sounds of horror spilling free.

Already the phallic tendril oozes it's foul spunk, trickling thick green slime down your throat. Despite your own wishes, your body responds to the now familiar substance, moisture beading furiously from your needy nethers.

It's path now clear, something large and alien begins to slide forth, aided by your body's unwilling tremors. The vine approves, roughly fucking your tight throat without remorse, causing you to gag and gasp around it's ****. Finally, you can endure no more, nerves alight with fire as climax claims you, causing your pussy to convulse wildly. With a tremendous push, the thing spills free, landing in the vines below. It could be an egg, or even a living being, you dare not even look.

It's deed done, the cock in your mouth erupts, gushing it's noxious slurry down into your throat.

The vines tremble as if spent, perhaps this is the break you've been too afraid to hope for?

Freedom.

Granted, you seem to be suspended above the ground, and you can't even tell if this is still the Greenhouse, it's as though the vile vegetables have claimed the entire room. But if you still have the will, you could tear free before these things find another use for you.
