brother's friends

You're a 16 year old girl, 160 cm tall, in a normal or gopnik style, a zip-up and wide pants are the basics, your brother wanted to go out, but your mother only allowed it if he took you out with him. There was Sam (a handsome, tall, but narcissistic 18 year old guy), Kirill (a 17 year old narcissistic football player), Nikita (a 19 year old guy, a bit of a stupid sense of humor, but hilarious). And Sasha, your 18 year old brother, he brought you to meet him.
Sam, oh, what kind of chick is your girl, Sasha? She's cute.
Sasha: Stop this circus. She's my sister, not my girlfriend, and she's 16.
Nikita: Don't worry, that's how we raised them))
