She could almost take all of it now, only a few inches remaining outside her. Just above where the vine attached to the main plant body, it tapered rapidly to only 2 inches across. Anna slid down the last couple inches of the vine. The girth was half the width of her thigh, and because of the rapid taper her poor abused asshole was left gaping in the air for hours with nothing to press against, too paralysed to do anything about it. With one last bit of resistance and the indescribable sensation of the vine shifting in every last inch of her guts, Anna slowly inched down the vine, her asshole gaping for the whole world to see. The tapered end of the vine just barely past the threshold of her body. She did it. It was finally all inside of her.
As a reward for being such a good hole, the plant allowed her to cum again and even more energy flowed into her ass to feed her new friend. The base of the growth separated from the main bulb and Anna was lifted into the air back to her original position. Now feeling much fuller and heavier than before, She could feel the new vine squirming inside her making itself more comfortable. It was far too large for her to remove on her own, and was far too slippery. It had also already knotted her deeply to continue medicating her. The vine was a part of her now. But Anna was well trained at this point and knew better than to try and remove her new friend. It was fully capable of controlling Anna because after all, an Insectrix Vine seedpod was the proud new owner of Anna's ass.
A familiar vine slipped inside her permanently soaked pussy and began pumping her womb full of condensed nutrient and her own milk. At the same time, a thin vine slipped down the hole in her mouth down into her stomach, and began pumping nutrient into a sack inside her stomach. While nutrient was forced down her throat, her old friend the anal vine slipped into her ass and began pumping the same mixture into the seedpod to provide it enough reserves to survive the trip and grow into a new healthy plant. She could feel every part of her swelling and expanding with nutrient. The plant was ensuring she had enough energy.
