You can have any superpower, but the first person to reply chooses a side effect

Turns out, the books you touch are actually quite satisfied and content.

It only works if you touch it with your penis.

The title of the book appears somewhere on your skin, and if removed you will forget any knowledge from that book, whether you obtained it through reading or your power. The titles must be legible, and cannot overlap.

but you must feel a paper cut from every single page of knowledge

Every book you encounter will always be written in a language you don't speak.

... but every page becomes blank just before you touch it.
