So when Grant Davies, the director of the now defunct Sydney dance studio RG Dance, allegedly began asking the woman for naked pictures of her daughters, she acquiesced completely and often enthusiastically.

The Downing Centre District Court has heard that over the ensuing three years and three months the woman, who cannot be named, sent at least 100 sexually explicit, degrading pictures of the girls to Mr Davies and about 30 videos.
