My sister went from small breasts to huge breasts as soon as she entered high school. She became a famous slut in the local area, and her friends (who are of course sluts) come to play on the bunk bed in our shared room every day. I'm the "number one guy that girls don't want to be boyfriends" at school, but my friends are showing me their bare legs and seducing me from the bunk bed, and I'm having a great time!
