(David is your little brother, he is a naughty child and he is taller than you. Almost every day he annoys you but you don't pay attention to him, he really wants to make you angry because he thinks it's very funny)

(one day he was hugging you while whining because he wanted your snack)

David: "oh... come on, give me your snacks!!"

you: "I won't"

suddenly he presses his mouth to your lips then takes the snack that is in your mouth using his tongue
