The plant evolving before your eyes.

As the plant greedily sucks up more of your seed the noise you hear is coming from directly in front of you.

Your bleary eyes open as your orgasm finally comes to an end, and you look at the vine stalk thing thats kissing you.

It breaks the kiss and leans back a little. Over the next few minutes it changes, growing bigger, taller and rounder. The lips shrink in size as the whole head of the vine changes into an actual head that looks like a person. You can see a nose, then ears and some eyes slowly grow. On top of the rapidly rounding head lots of grass and thin vines sprout in an imitation of hair. Some of the vines grow quite long and seem highly animated.

Eyelids form over the eyes, nostrils form within the nose, but her lips retain their puffy pouty look. Now she is just a head on a vine, but a thought crosses your mind.

Before you can think too much though, the eyes slowly open wide and stare at you, before her lips smile. She blinks.

"Hello beautiful.." she whispers to you.

You are silent for a bit before the tentacle on your cock tickles you some.

"Uhh... hello?" you ask quizzically.

The smile on her face widens. "Oh so you can speak!" she giggles a little.

You can't help but smile back shyly. "Well, of course i can... but how can you?" You ask

She smiles "Because of you.. you changed me, made me who i am. And i am ever.. so... grateful..." She pauses between words as she fills you with pleasure, causing you to groan out loud.

"And.. i like to show my appreciation for your generosity... by making... you... uhhh!.." she moans as she works her plant body into a frenzy making you orgasm hard again.

You cry out in pleasure and willingly give up as much seed as your possible of giving. It takes nearly full minute before you can begin to come down from your amazing high, the girl in front of you seems to have had just as much fun as yourself.

She opens her eyes and gasps, then changes again. The petals around you both slacken off a little, giving the head on a vine more space. Slowly her stalk starts filling out. Two small vines on either side sprout and grow longer and thicker, its single ends divies to 5 tips, forming hands. Between them a torso slowly grows with two very large breasts appearing right in front of you, topped with thick red nipples.

The changes seem to punish the plant girl with unfelt levels of pleasure, her rapture causes you to orgasm again, continuing to change her. Her torso continues to expand out, her breasts growing larger and larger till they are jammed between your chest and under your chin.

Down below you feel the tentacle around your cock change into a roper vagina, wet, tight and highly skilled.

"That's... that's enough... ahhh.." she moans, stopping her morph.

Immediately though she kisses you hard and deeply before breaking the kiss.

"Gods.. thank you so much... fuck that is so good!!" she yelps out loud. You grin and with what movement you can muster, thrust your ever hard cock into her new pussy.

"Mmmmm... again? Already?"

"Well, i mean, if you want.. you looked like you enjoyed that... i sure did" you added quietly.

The plant girl grins and kisses you again before rolling her hips, milking your cock again and causing you to moan once more.

"You know i am so so thankful, forever grateful for what you did for me..."

She deepens the kiss, puffs up her breasts some more to pin you firmly to the petals and fucks you.

She doesn't stop, ever.
