Use the Rifle.

You are supremely confident in your skills with the rifle, so you adjust your sights and take aim on the vines binding Serena's arms. Depressing the trigger, you send a beam of pure energy lancing into the plant assaulting your crewman. Your shot it perfectly on target...but much to your consternation, it has no negative effect on the tree. Even worse, it appears to invigorate the tree. The vines penetrating her pussy and ass begin to move with more force inside of her, and the flowers grasping her breasts enclose them even more tightly. A moan escapes from around the vine in her throat, and her eyes roll back in her head....you hope from her going unconscious for her sake, but you fear that you might have just force an orgasm on her.

Cursing to yourself, you quickly sling the rifle over your shoulder. You have no choice but to try the knife now. Pulling it out of your back, you prepare to descend down into the vale to rescue the helpless woman. Unfortunately, in your eagerness to save her, you failed to notice another tree just like the one binding her standing just a meter away from where you watch. Vines snake out rapidly and grasps your wrist....yanking you back forcefully against the iron bark of the tree. The force of the blow is enough to cause the knife to slip from your nerveless fingers. You try to fight and kick, but the vines around your hands are too strong...and soon matching vines wrap around your ankles to securely bind you.

You wriggle helplessly as new vines begin to roam over your body. Sharp edges cause your uniform to separate and tear wherever they pass, baring your pale skin underneath. You fear you know what they are seeking for...and your fears are realized after they reach your nether region. The tearing vines move on, but new ones quickly move to take their place. You try desperately to close your thighs...but the vines are too strong, and you remain completely open and vulnerable. The new probes press against your labia, and quickly worm their way past your last defenses and into your pussy. Another seeks out your rear, and repeats the process in your ass. You cry out in horror as you are taken, but this only draws yet another vine that plunges past your lips and into your throat. As your body begins to bounce under the assault, similar flowers descend from the tree to attempt to enclose your breasts. Your chest is a bit larger than the Ensign's, so the flowers aren't quite as able to envelop your tits. But they are still able to provide ample purchase, and begin to suckle at your nipples. The total stimulus is more than you can bear. You have been trained to deal with pain....but this utter pleasure is something totally different. The vines are more relentless than any lover you've ever had, and you are helpless to stop yourself from enduring an intense orgasm.

Your release of juices is what the plant seeks, and does nothing to stop it's assault. It takes a little longer, but you cum again soon. And again.... And again.... Eventually, your sanity flees in the face of wave after wave of pleasure. Does someone eventually find you like this? You don't care. You wouldn't know if they did. You are lost.....
