Gender change at school

I am Jake a tall 18 old boy who always wanted to be a girl because I think girls have a exciting life. But that is impossible so I live my boring life. Toady I woke up at 6 and went to bathroom and did a jerk for 10 minutes. I wore my school dress and went to the school . I entered the schools and went to my boring classes. In between I went to the washroom for the nature's call. While I was going to the washroom I saw some aurora at our HM room. I went to the room and found noone and the aurora to disappeared but I found some change happening in body. I felt weak then earlier and my face has been smoothen my hairs went blonde and were falling to my eyes. My pants changed into our school skirt and big balloons popped at my chest and my lips are having some lipstick on it. And my butts have been widen. I suddenly realise I have became a girl . I was happy but scared and I rushed to the girl washroom I saw in the mirror that a beautiful blonde with big boobs of F cup and saw my wet pussy. I saw my boobs and cunt are covered with a bra and panty. I was having **** so I went to my classroom.
