[Story Search] looking for a cock growth story about a college student getting a pen and drawing/writing on a paper, eating that, and that becomes reality

I think the main character was a college student named ian that gets gifted this magic pen that lets him change reality when eating a piece of paper that was written on with this magic pen.

I dont know where i last read that story, but i think that was last year/the year before.

Please help me find that. If nothing else, i might write it myself again or something.
