mattheo riddle brothers bestfriend

part one

it was the day before summer break and you were in your dorm packing to go to your families holiday house in italy. you were sat on your floor with all your bikinis spread on the floor around you, why was it so hard to decide what to pack. you had narrowed it down to your dark red one that hugged your curves and showed off your figure and your midnight blue one that made your eyes pop.
"i would say the red one" a lazy drawl startled you and you looked up to see mattheo riddle leaning against your doorframe looking hotter than one should be allowed to look.

you rolled your eyes, "in that case i will take the blue one, thanks riddle, anyways what are you doing here?"
"nice to see you too, theo wanted me to bring you this." he chucked you your bag that you had lent to theo a few months ago.
"ahhh, is that all?" you could never think straight in his presence, something about him just threw you off.
"yep, see you tomorrow morning princess"
"tomorrow? what do you mean? also im not your princess" you snapped.
"didn't theo tell you?? i'm coming to italy with you guys" he knew theo didn't tell you, he just loved winding you up.
"you're joking"
"nope, see you tomorrow" he winked at you over his shoulder before leaving you alone again.
"ughhhhhh" you threw your head into your hands, there goes any chance of having a relaxing holiday. this was going to be hell.

your first two days you spent catching up with your parents, lounging by the pool and reading your book, it was heaven. and to make things better theo and mattheo were barely at home, they spent their days down at the beach, so you didn't have to put up with mattheo's annoying presence. but your good luck ran out the afternoon of your third day there.

you were out by the pool when your parents called you in for lunch. you slipped your cover up on over your bikini although it didn't actually do much to cover you up despite its name. as you walked into the dining room 7 different heads all turned to look at you. nobody had thought to tell you that theo and mattheo's friends were joining you for lunch. one of the boys whistled at you earning themself a slap on the arm from theo. "dude no, she's my sister, she is off limits i mean it" you rolled your eyes at theo's overprotectiveness and made you way to your seat, all 7 pairs of eyes following you.

once you had sat down you looked over at mattheo who had a murderous look on his face, his jaw was clenched and his eyes were darker than you had ever seen them before. you tried to ignore him and continue with the lunch but you couldn't concentrate as you felt the heat from mattheo's stare on your face.

"y/n can i have a word??" mattheo's tone was cool but you could sense the danger in the air. you got up and followed him into the kitchen.

"mattheo wha-"
he cut you off by grabbing your wrist with strong force.
"what the fuck do you think you are doing?"
"one, ow can you let go of my wrist and two, i'm not doing anything what are you talking about?" you tried to pull your wrist out of his grasp but it was no use his hold only tightened.

a sardonic smirk spread across his face before he leaned down to whisper in your ear, his hot breath against your neck sent a visible shiver through your body
"you know exactly what you are doing, wearing that tiny fucking bikini infront of all these boys, letting them see what is mine"
you couldn't believe him.
you straightened yourself up trying to hide the effect he has on you.
"i am not yours mattheo, and im in my house if i want to wear this bikini i will wear it i dont care what you say."
"drop the attitude y/n, i mean it"
"and if i don't?"
"enough."

and with that he left you alone in the kitchen wondering what the hell just happened.
