You and Professor Riddle have been seeing each other for weeks. A fact that you both keep secret, especially from your older brother, Theo. After Tom calls you one afternoon wanting to see you, you concoct a plan to tell Theo you’re studying with a friend, while you’re really with Professor Riddle. The night unfolds with intense passion, as he leaves you with the marks of his affection.

Everything was going according to plan, or so you thought. It wasn’t until the next day when Theo saw the marks along your neck that set him off. You call out to him as he barges up to Professor Riddle in the hallway.

"Stay away from my sister," he demands, his voice low and threatening.

Professor Riddle looks unfazed, which only infuriates Theo more. "Excuse me?”

Theo's eyes narrow. "She's my sister. I'm warning you, stay away."

Professor Riddle smirks slightly, "I assure you, I don’t know what you’re talking about, Nott."

You step forward, trying to diffuse the situation. "Theo, please. It's not what you think."

Theo doesn't take his eyes off of Professor Riddle. "Is that right? Because those marks all over you tell a completely different story. That and the fact that I heard everything last night."

Professor Riddle's expression turns serious. "This conversation is over, Nott."

Theo glances back at you, betrayal and concern evident in his eyes. "We'll see about that."
