You didn't notice the stepping stones leading to the tree, and as you run straight at it, you realize that it wasn't such a smart idea to run through the soft soil. The soles of your shoes are ripped asunder as roots shoot from your feet, digging deep into the soft soil with ease. You try and continue your run, but to no avail. You shout for help, but no one is around to hear. Your feet are in the ground, for good it seems.
You take a deep breath, and shut your eyes thinking, "Maybe I'm dreaming?" You open them to find your fingers have grown longer and a sort of brown in color. You wonder what you're going to do when you have an odd sensation in your pants. The crotch is ripped away from them as your solidly wooden cock emerges, a similar, though much smaller, blue-gray fruit as the one you ate grows from one of the smaller branches of your once manhood.
You stare in horror at the sight, but somehow aroused. The fruit grows slightly, and a fruit bud makes itself known on your palm which has now been covered by bark. Your legs are now solidifying and bulking out, pants ripping apart easily. You see your legs are covered in bark as well, and you are unable to move anything below your waist. You feel your legs almost as they were, but they seem to have assumed what now feels like a 'natural' feel.
Your branches and limbs all continue to grow, and more leaves sprout over the branches. Your arms have a sudden urge to be raised, and without a fight, you raise them. A branch starts growing from your nose with more fruit buds on it, and the aroused feeling seems to increase. You're not sure what it is, but the longer this goes on, the less scary it feels.
More branches sprout from your head as bark starts climbing up your chest and "down" your arms. The branches over your head flourish and leaves seem to explode from them rapidly, fruit buds appearing all over. Like your legs, all that you lose movement of you don't lose the feeling of. Your arms still feel like arms to you, just much more solid and... bountiful, each limb adding to your sensations.
You start to get a funny taste in your mouth, realizing that it must be your saliva becoming a sap. Your tongue begins too feel a little funny as it grows a little woody and leafy, you have a similar urge that you had with your arms to stick out your tongue. As you stick your tongue out, your mouth solidifies shut and your tongue flourishes in a similar manner to the branches above.
You no longer need, or are able, to breathe, but somehow you let out a sigh-like moan. The aroused feeling has been growing slowly as you become the tree like you ate from, you quietly close your eyes as they are covered by bark.
You no longer have any senses, but you are aware of your surroundings. You still see the room around you, and are free to look out from any angle now it seems. You hear and feel a breeze coming through an open window way up high you never noticed before. An overwhelming sense of peace and calm seems to envelope you, feeling somewhat both like a decent arousal and that feeling of sitting under a tree on a sunny breezy day.
You are a solid tree, about only a foot or two taller than you were as a human. The fruits and fruit buds on your branches start to grow and thicken into larger fruits, barely half the size of the ones you ate, like a small melon size. It will take many years before you are the size of the tree that made you this way, but the worries you had at the start are long since gone, as well as many other problems you may have had in the back of your mind. You are content...
