Sienna shows Anna a book about handmade porn, and they discover that people throughout history have always created sexy images to masturbate to, even carving them from stone and ivory. The girls discuss what they think about when they pleasure themselves, and happily find that they’re both aroused by fantasies involving denial and release. “Well, since we have the idea…”, Sienna teasingly suggests, unzipping her rainbow shorts, which match her colourful hair. As they undress, Anna’s eyes light up when she sees her friend’s perky nipples, then she asks for Sienna’s help in removing her lacy bra, to free her voluptuous boobs.
