You don't know why, but you think that you can beat him. Swinging your fists, you aim for its wooden torso, but it's like hitting a tree...

In an instant, its strong, vine-like arms lift you from the ground, and you think that you are going to be killed.
Unfortunately, you are wrong, the creature uses an eldritch spell to bind your arms, rips off your clothes, and forces you to open your legs, revealing your pussy and ass.
The creature returns to his lair between the dark tall trees, and you can just scream.
His roots, invade your ass, and you moan in pain, drooling over yourself, but the creature keeps looking deeper and deeper, once is deep enough, he feeds with the contents of your bowels like a parasite.
After long hours, you feel a strong urge to go to the toilet, and you release a thick white fluid from your ass. A deep voice resonates inside your head, he explains that you just expelled your clean anal juices, and from now on, you will feed his roots with your waste. He will feed you and you will have a nice relationship. Weak and degraded, you babble, drooling over yourself, but the creature doesn't care.

Day after day, he feeds you with fruits, vegetables, and water, and impaled by his tendrils, you release the clean white fluid.
After a long, long time, your skin becomes hard and brown, like the bark from a tree, and you become a part of him, merging with his thoughts, desires, and life force. You understand that you must find another human to survive, and you slowly start to walk in the park, looking for a new victim.

THE END
The walking invasive tree ending
