You remember that one of your favorite superheroes in comics was Arachnid-Girl. The story of how an innocent nerd teenager named Phoebe Parker, got transformed into a superhero that can climb walls, and shoot webs, thanks to getting bitten by a radioactive spider, while also saving her boyfriend.
Not to mention that Arachnid-Girl while being energetic, and sexy also had more villains than any of your favorite superheroes combine. You could imagine yourself being a sexy girl with spider powers, being able to wrap your girlfriend in a web, while at the same time having lesbian sex with her as she was wrapped in your webbing. You could also be able to grab stuff out of nowhere without walking five feet. Given those kind of attributes, you decide to give it a try.
