My Porcupine (Modern AU MadaraxReader)

This is my first Anime fanfic so I'm apologizing ahead of time because it may be trashy.
Y/n is a 21 year old college student. On her first day back at school (shes a 3rd year or Jr.) Y/n meets a man, to students he's know as Mr. Uchiha, but to you he'll soon be know as Madara...(He's Y/n's math and history teacher just so you know). Read to find out what happens between the two of them. P.S. Madara is going to be 34 in this.
This is an R rated story so just a heads up, there will be lemons...
