Y/n is in her last year in hogwarts in slytherin.She was a pretty good student and was pretty attractive and a popular student,which normally Professor snape wouldnt like,but somehow he loved her.Since the beginning of the year each saturday she would go to his private quarters and sleep with him. But last saturday they didnt cause snape was busy but he regretted it cause that next friday,he gave her class and he couldnt help but look hungrily at her,which no one noticed only her,but she also looked at him that.
