Severus Snape X reader. A/n the ending gets a bit off topic 😁

When pranks are played at Hogwarts you tend to think of Fred and George Weasley,but would you believe me if I told you that this prank came from Harry Potter himself? Maybe,you see Harry had had enough of Snape and had wanted to get his own back on the potions master for some time now. And it being nearly Halloween Harry decided now is the best time to play his prank,only it didn't go as planned. I made my way to the dungeons to help Snape prepare for his next class.

Upon arrival I see that Harry is sat there writing lines on some parchment,I snatch the parchment from him and read
"I will not attempt to cover professor Snape in slime"I said" Was that really your best plan?" I asked the boy handing back his page
"It was more Ron's suggestion than mine" Harry said setting down his quill and looking up at me
"You're Sirius Black's godson, didn't you think to ask him for help?" I said sitting down at the desk infront of him.

"No I didn't think about that" Harry admits
"Or you could have come to me,I have a whole list of pranks I want to play on Sev sometimes" I said
"What do you see in that foul git?" Harry asked
"First don't call my man a foul git and second you don't see him like I do. He's got a soft side" I said,Harry gave me a confused and slightly disgusted look" Anyway enough about that,how about I give you a better prank for the grump"

"What are doing in my classroom L/n?" the familiar deep voice of Snape said
"I was um...I don't know actually..." I said trying to think of why I am here
"If I recall correctly you where just about to tell Potter,how to prank the grump" Severus said walking over to us
"I did,I don't remember"I said smiling innocently at him
"Get out Potter" Severus said,Harry got up from his seat and almost ran from the room. Leaving me alone with Severus.

"I'm guessing you heard what I said to Harry then?" I asked looking up at the potions master
"Indeed" was all he said" You are a bad influence on that boy"
"I am not" I defended myself
"You are a bad influence and you will be delt with accordingly " Severus said leaning over me
"What will you do?" I asked feeling slightly scaroused at this point
"Don't worry my naught assistant,you will enjoy yourself..."
