My chest exploded with excitement, his words making me clench my thighs together. Mattheo shoved his knee between my legs making me gasp, his touch finally returned to my body. "Don't do that." I squeezed my thighs around his thigh, making him groan. "Fuck Aurora." Mattheo rasped. I rolled my hips against him, a strangled moan escaping my lips. "You're pretty fucking pathetic." Mattheo spat releasing my neck, his hand moved down my chest, filling my stomach with anticipation. "You're really that needy?" Mattheo asked. His fingers brushed over my clit making me squeeze my eyes shut, holding back a moan.

» I didn't know you had a sister, Potter. «

A girl decides to shift to hogwarts and is super excited! She makes friends with many people but make some enemies. Will she do well in her new school?

If you're into messy romance, angsty smut, and a very chaotic friend group, this stories for you. This is a childhood friends to lovers between Draco, and Isabella (Mattheo's reckless twin sister), but they're both huge players, toxic, addicted to power, and very lusty for each other (which Mattheo does EVERYTHING to stop) Isabella and Mattheo grew up with the Slytherin gang, but leave Hogwarts in year 4. Though they come back two years later due to an incident... Draco and Isabella know each other inside out, however things have changed the two years they spent apart. Draco doesn't settle, he plays around with girls, for his own amusement. Isabella's never had a guy treat her right so she flirts with every guy she meets. Mattheo protects Isabella from any guy who tries to touch her, but it seems he has to protect her from his own friend. Unless he doesn't find out... 
As Isabella and Draco continuously destroy each other (fun!) the "incident" slowly comes to light. And every side character (Mattheo, Theo, Enzo, Pansy, Hermione, and Astoria) have their own mini plots!
 So yeah! It's very plotty, and very smutty (there's a reason it's called the Lock to His Key 😉) ------------------------------------------ A plot full of toxicity, smut, lying, cheating, betrayal, secrets, plot twists and everything else.. Will it end well? That's for you to find out... Isabella = Maneater Draco = Womanizer Mattheo = Overprotective brother Theodore/ Lorenzo = Comic Reliefs Enjoy.
