Ben Tennyson: Aliens' Mating Season

There is a fan fiction. Cartoon Network owns the series. This is fiction and the characters aren't real. This is a choose-your-own erotica adventure that involves Ben 10, Gwen, and other characters from the show. ⚠

I stopped watching the series after Alien ****, and it's been a while since I saw the original series. I don't aim to be perfectly accurate with the series. That's what makes fan fiction fun—you can write the story however you want.

All characters in this story are at least 18 years old.
