“Watering them to see if they’ll grow.”
This is really one of the most ridiculous and almost cute submissions. Life with her tiny tits must have been so terrible for her (like for all flatties) that she is now willing to do anything, however ridiculous or unlikely to work, for a tiny chance to finally make her tits grow. They stopped growing early on in high school: the girls started bullying because they realized she is inferior to them; the boys because she was the least attractive girl so they could abuse her and make of her without the risk of being too harsh and risking their chance to fuck her. With her flat chest, she simply had no choice.
