You and Mattheo have been best friends since birth, in 2nd year y'all started dating,he became a death eater and shortly after you did too

Were sitting in Snape's class, you were bouncing your leg and Mattheo had his left hand on your thigh, as Snape was talking Mattheo's hand slowly made it's way up your thight till it got to your entrance, he slowly moved his fingers under you skirt shorts and panties, he started moving his fingers slowly and in circles, you gasp when you feel his fingers, he smirks as you cove your mouth, you leg stops bouncing

"everything alright, princess?"He whispered into your ear, a smirk on his face as he continued to finger you
