you add back that women now lactate but then you add a new line
women now lactate from their breasts but they do not only lactate milk. when a women enter puberty and her breasts start growing she will start lactating a random liquid. the most common liquids to lactate are milk, ice cream (any flavor), milkshakes (any flavor), honey, soda (any type), coffee (any type), cum, pussy juices, and water. 15% of women also have a mutation that causes them to lactate different liquids from each breast. 30% of women have multiple pairs of breasts this can also stack but the most ever reported is 8 breasts on one person. 20% of women will also as well as lactating from thier breasts also be leaking a random liquid from thier pussys at all times as well. the rarest thing a female can lactate is a liquid called "estrogen milk" it is called this because it contains such high amounts of estrogen that any male who drinks it will instantly transform into a lactating female. every time a women has her period the liquid that she lactates will change to a new random liquid. and everyone will be aware of this change but not know the specifics of how it works.
you show this change to your sister and she says
"sounds erotic you little pervert but i like it"
"oh and one more change" you say as you change your breast size from C to E
you then close the book and feel your breasts start growing but before you can focus om your own changes you hear your sister moan and see a liquid coming from her breasts
