Your torso, and slowly your entire body began turning green like the surrounding plants. Your arms then began shrinking eventually becoming stubs, and then nothing at all. Your legs fused together, and you felt them dig into the ground beneath you, and you then knew that they weren't legs anymore. Then your head changed becoming flatter, wider, and your hair fell out onto the ground. Your skin on your fave then fused with your skeleton, and sharpened into long dagger-like needles giving you carnivorous teeth on the outside of your mouth. As for the inside of your mouth you felt spurs form across your tongue, and your tongue widened to match your new mouth.
You then noticed your vision had also changed, and you felt your eyes pull into your body, and becoming nothing. Despite this you could still sense everything around you, and you could feel your surroundings as if they were part of your body. You then noticed something odd, and it was your dick which had remained unchanged up until this point. That is until your dick turned green and grew out like a long vine over 10 yards, and you seemed to have prehensile control over it like an arm. You then felt the tip producing liquid similar to sap, and your balls grew larger too. Suddenly you felt as if your balls were hanging from your body as if by a string that was attached to you, or a stem. Your balls then grew again, and you felt them stop at a certain point, and you felt as if they could fall off of your body.
"Ah, such a perfect creature for such a perfect environment." The witch said as you felt her walking closer to you.
"What did you do to me?" You tried to say, but the voice just echoed in your thoughts
"Why you're something that I like to call a dominant venus animal trap plant. You can't speak so I gave you telepathy as a method of communication. Anyways soon enough you should have multiple sprouts like you now growing around the entire palace, and maybe you could extend your boundaries to the world." The witch said
"What's wrong with my dick, and my balls? Why are they...those?" You asked
"Why your penis has become a vine for attracting insects such as knats, or anything that enjoys the smell of your sap. Your balls are now your fruit, and can be used to bait too in order to attract larger creatures like fruit bats, or stuff like that. Anyways you are an ever growing weed that loves to extend it's boundaries, hell I bet you're even doing it now with your new roots, feeding off the energy from the palaces water, and sunlight too by your roots, and eventually those roots will be yours. The palace will be you, and you it, what's more is you can create more of your own sprouts by devouring animals. They will then be converted into nutrition, and once you have enough you can make replicas of yourself above ground. So spread your roots, invade the palace, and feed on whatever comes, just do what you plants do best and grow." The witch said
"Wait what? You mean that I can literally be at every place of the palace here, and all at once?" You asked
"Yes, and you'll likely grow more vines, and fruit than just the two you have now. Also I decided to name you Overgrow, it's what you do anyways. Also I'm going to need one of these if you don't mind." The witch said grabbing one of your fruit hanging from your vine dick. The witch then twisted it, and picked it from your body, and it hurt, but gave you a sense of pleasure as she yanked if off of you.
"I needed one of these for a project that I'm doing, and your fruit seem ripe and ready to pick. I'll leave you the other one for looks, and don't worry they always grow back." The witch said leaving the room
As she walked away you felt yourself rapidly expanding through your root system, and you felt you have taken over the floor of the surrounding rooms, and walls around them. You brought the tip of your dick closer, and felt it producing sticky sap from its tip which looked clearly like a dick still, but green. You had urges to take it's sap, and spread it on your tongue for some reason. You at first refused, but as you noticed knats becoming more enticing to you, you also couldn't catch the knats in time before they realized what you were doing. You then sighed, and opened your mouth wide, and suddenly your dick began producing large amounts of sap when you placed it onto your tongue.
You immediately took your dick out of your mouth, and felt your tongue was heavily coated with sap, and your spurs didn't mind it that much. "What do you do now dick mouth?" You thought to yourself because of what you just did. You then remembered what all venus fly traps do, and wait for their prey. You sighed and thought to yourself,"This is a new boring, and disgusting life you have now...Overgrow." You then opened your mouth, and began waiting for something to happen, until...
