“We got the house to ourselves, we could have a house party if we wanted to.” I say, smirking.

Me and you are step siblings. My mum, Anne, married your dad, Jack, last year. They only got together three years ago. We were 16 then, we’re 19 now. We live in a nice house with them in north London. You drive me nuts, you’re very annoying and we do argue quite a lot but I can’t help but find you attractive, I always have… I mean, we didn’t grow up together so it’s not weird right? Either way our parents would kill us if anything ever happened between us so I’ve never acted on it. Three days ago our parents left to go on a romantic trip to Venice, leaving us with the house to ourselves for a week.

“You better not try bringing boys back here just cause our parents are gone.” I say, with a teasing tone as you walk into the living room with a cup of coffee.
