The lucario was walking in the forest, hunting for something to eat. He suddenly heard a voice calling for help, but saw nobody around. As he wanted to continue looking for his next meal, he heard it again.
Hey, down here!
He looked down, and saw a small umbreon yelling at him.
Finally, someone noticed me, i need your help, something bad happened to me!
He carefully lifted up the micro umbreon, hey buddy, what happened to you? Lets sit down and explain, maybe i can help you.
The umbreon started to cheer up, finally someone who can help him. I ate some weird berries, and suddenly i shrank!
The lucario asked, can you explain me how they looked like? Im actually looking for some food myself, not that i accidently pick them.
The umbreon explained him, he making a note to collect some later, they might be very usefully.
He told the umbreon, he might know how to help him, which made the umbreon very happy.
With some smalltalk he distracted the umbreon, while rubbing his dick, making him unaware from what is about to happen.
The umbreon started to notice his, now full erect dick. Hey buddy, you are bit, well, stiff down there, he shily said.
Oh, sorry, i have been pent up bit for the last few days, but i know now how to help you!
The umbreon was about to thank him, as he noticed what is happening. He started to yell, dude, what the fuck are you doing, as the lucario put him into his shaft.
Im helping you! You dont have to worry about to turning back to normal as cum, and i can get off! Its a win for us both!
The umbreon wanted to protest it, but got pushed in already. He struggled, begged for mercy, for help, he didnt want to die.
It pleasured the lucario alot, the desperate ones are the best ones, he thought.
After bit more than a minute, the umbreon was gone. With a loud moan the lucario ejected what was left of it.
Thanks buddy, you really helped me there, and see, you dont have to worry about your size anymore!
Well, lets get going, im still hungry, and want to find someone to eat, and pick up some of those berries on my way, they seem to be very usefully.
He turned around one last time as he was walking away, looking at the still steaming puddle of cum, oh well, i didnt even ask for your name. Not that matters now anyway, cum doesnt need a name, he started to laugh, as he walked away.

Its known that the woods are dangerous, easy to get lost, or a hungry predeator. The family and friends will never know what really happened to him, that he became a little cocksnack for a cruel pred, and ended up as a cum stain somewhere~
