Which Riddle

This is a story of oc x Tom Riddle x Matteo Riddle. The Oc is named Amelia, although you can imagine her to be whoever you'd like, I will limit how many physical characteristics are included. Amelia Nott -Theodore Nott's sister- is new to Hogwarts, joining at the beginning of her sixth year, when she meets the sweet and chaotic Matteo Riddle. However he isn't the only Riddle brother she's getting to know, Tom Riddle, with all of his darkness now enters the picture. When complications come up, how will things be handled? What will happen?

AN: This is not following the same timeline as the actual Harry Potter series, I find it to get repetitive. All characters besides Amelia and whoever else I create along the way belong to J.K.R. Matteo and Tom are brothers, as obvious in the description, but they're very competitive but still close with each other. As stated above as well, Amelia and Theodore are siblings. This will contain mature topics, which may include; sexual scenes, kink exploration, blood (?), sh, ed, and teen pregnancy. If you are sensitive to these topics or just aren't interested, feel free to find another book.
