Mary had just finished her potions class and was walking with Ron and Hermione to defense against the dark arts. Hermione once again asked, "What is up with the two of you? Neither one of you have said more than 5 words today?" She paused to give each of them a long look, she was looking annoyed and slightly suspicious.
"Seriously what did I miss? You both look guilty as sin!" she hissed. But just then, luck was on Ron and Mary's side, when they were joined by Ginny, Ron's sister. Who was asking if they had completed the home work due. All talk came to a end as they entered the classroom.
Mary cast a guilty look towards Hermione, how could she tell her friend why her and Ron had been so awkwardly quiet. That they had in fact, the day before spent the afternoon fucking, along with Ron's twin brothers, George and Fred.
It hadn't been planned, but when they had accidentally caught Mary fingering herself, things just got out of hand. Hermione would never understand, how could she? She had never so much as even kissed a boy yet.
Mary had been the same, up till the ride with Professor Black to Hogwarts. When what had started out as Black raping Mary, turned into a lesson on the pleasures of the body. Mary felt herself blush, between the thoughts on the things done to her. First by Black, now by the Weasly brothers, Mary had turned into quite the needful little slut, in a very short time.
Mary got butterflies in her stomach and felt flushed and breathless from the memory. She also realized that she was incredibly wet. Sitting in her seat, in none other than Professor Black's class room, waiting for him to walk in any moment.
Just then the side door opened, and in swept Black. His eyes went directly to Mary as he made his way towards the head of the class. As he walked, he made slight twist of his wrist, his wand in hand. Mary gasped out loud, as she suddenly felt invisible fingers enter her wet pussy. She felt the fingers work her her already wet swollen pussy.
Mary held her breath, trying to keep herself from crying out. She knew that she was already close to coming. She gave a fearful glance around to see if anyone had noticed. But again luck was on her side, as the other students continued to take their seats, no one seemed to notice her reaction.
She also knew that there was no way that she would be able to keep herself from crying when she did come. She looked to Black with both fear and a silent plea. He apparently understood, and with another slight wrist flick, the fingers were gone from her pussy.
Mary felt relief at the knowledge that she would not be making a spectacle out of herself. She also felt disappointment that she would not be able to finish what had started, she would not be able to come. She was incredibly horny, being the needful little slut that she was.
