White Lillie of the North

This flower, even when plucked decades ago, remained as is, it was as if it has some kind of purpose. When ingested in the form of a brew by anyone the special fluids inside the flower will react with the presence of BBC, causing the taker to become extremely sensitive and aroused while near a BBC, If at some point they can't resist the temptation anymore, they will actively search and look for a BBC, and will compulsively have a sex with him. When that happen a trait will appear, suggesting that this character is in the progress of turning into Pure White, I will call this trait White Flower Bloom.
