• Cormac X Reader • "Veritaserum or Dare?" "Dare." "Okay. I dare you to break Cormac McLaggen's heart." Cormac McLaggen. Athletic. Charming. Gryffindor heartthrob and heartbreaker. He can get any girl he wants but doesn't stick with them for long. Most think he's afraid of commitment, others don't really care what his problem is, they just want him to get a taste of his own medicine. So, during a game of Truth or Dare, one of y/n's friends dares her to make Cormac McLaggen fall in love with her and then break his heart like he's broken so many others. The only problem is that the more time she spends with the notorious player, the more she might actually like him. • WARNINGS • - Foul language - Smut 20k words
