brother and his friends #1

You were your brother Derek's younger sister; he was 17 and you were 14. Your parents went away on a business trip for a week, leaving you with your brother. You often liked to tease him, but things didn't always work out in your favor. It was an ordinary winter day. Your brother Derek came up to you and said his friends were coming over. You didn't object. Ten minutes passed, and finally, your brother's friends, Simon and David, arrived. They were talking quietly, sitting on the couch in the living room. You got bored, so you went into the living room to join them. When you arrived, everyone looked at you, you said hello to them; you had already met before. When your brother and Lucas went to the store, you were left with Simon, you thought and decided to take advantage of the time, going up to Simon, you asked permission to stick him a small sticker, to which he agreed, you immediately took your stickers, came to him and started to act... When your brother and Lucas arrived, they entered the hall and saw such a picture: you were sitting next to Simon and his face was covered with your stickers.
