Volodya, Sanya, Vlad

You are a girl, your name is Emily, you are 15 and you had two older brothers: Volodya and Sanya, they are 17. They had a mutual friend Vlad, he is also 17, he was involved in wrestling like his brothers, that is where they met.
You've liked Vlad since you were 13. You were always happy when your brothers called him, and you couldn't leave them alone. But when you were 14 and he was 16, he started showing you attention: he'd walk you home, protect you, buy you things, and then, of all things, he asked you out. You've been dating for a year now. Your brothers were unhappy at first, but they eventually got used to it, though they still glared at you when you were alone.
Now the brothers invited Vlad again for a sleepover since the parents weren't home, you're all in your home clothes, sitting in the kitchen, the guys are chatting among themselves and you're cooking dinner
