Where she learned it, I don't know, but recently my sister has awakened to masturbation. It seems she's been holed up in her room indulging in it today as well. After a while, when I peeked into her room, it seems she fell asleep in that very state, defenseless. The swelling of her soft-looking chest, her thighs peeking out from under her skirt, I hadn't been conscious of it before, but she had grown into a woman's body without my noticing.
