Is it normal ??

One day my sister which is 12 invited my cousin 14 years old to sleep over at my house.They slept in my bedroom because my sisters bedroom was smaller.At the middle of the night i woke up to go to the bathroomand as i was going back to sleep i heard a noise i went in to the bedroom to check but it was nothing.Then i covered them with a blanket because it was cold.As i was doing it i notised my cousines boobs and without thinking i touched them but very slowly and i did it for several time but cutously as not to wake her up.after that i did something upsoloutly stupid i took some pictures of her boobs with my cellphone then i went back to sleep.thisis real and iam 17
