She uses one of her hands to try to pull it out

Her decision was to use one of her hands, and hopefully yank the thing out of her. She couldn't tell how high she was, so it was a terrifying prospect to sacrifice one her hands to fight it off, potentially risking falling off, but her dignity was important to her. In that moment it appeared worth the risk.

With her right hand, she let go of the stalk she clung to, and without wasting time, put it straight down to the nether regions. She could already feel the uncertainty how long she could hold on before she might lose her grip with her left hand and fall. Reaching for the plant cock, she managed to grab the base just below its large head, and pulled hard despite her instincts telling her not to. She managed to pull it an inch out, and there was still two or three more to go. But it began resisting, each second she held on she could feel it intensifying. Focusing exclusively on the bastard trying to enter her, she threw caution to the wind and began fighting more vigorously, which destabilized her greatly. It was difficult enough to hold, and then suddenly, her left hand slipped.

The brief second of falling triggered of course an impulse of panic. For a fraction of a second she stopped fighting the invader, and instead tried throwing her arms around in hopes of grabbing onto to something. But she didn't need to. The plant cock absorbed her fall, and with her weight pushing down on it, it found it easy to reenter her, going as deep as anything could into her cave. She could feel the little bumps of the kernels drag themselves into her. At this moment, Alison was hanging in the air, supported solely by the thing inside her. Still in the frame of mind where she couldn't afford to think, her instincts remained in control and decided on the best course of action, keeping her safe from falling. Alison closed her legs and held them around the stem of the plant cock, locking herself onto it. Once she was able to hold on for a good firm position, her mind was able to slow down and think, and it realized that she now had given full entry to her pussy. She was held in the air, impaled by a plant cock thing. The stem of the plant gently swayed in the air, shifting her balance some, and she could only respond by shifting her weight and moving her legs some.

The phallic plant began slowly twisting around, massaging her on the inside, while also slightly altering the angle that in which it invaded her. It stimulated Allison enough to gather several moans from her, which she instantly regretted but couldn't control. She swayed in the air, trying to keep her moans as quiet as possible as the thing moved unpredictably inside her.
