So, they’re coming from a similar situation as you are. Like you will with her, she’ll share her comfort levels of different interactions in the shoot, then she’ll undress, masturbate, and have an orgasm. She might watch you, and touch you how you asked (if she’s comfortable to do so), just as you will.
The “other” model has been through the same process as you so far – they read the information on our modelfor.abbywinters.com site, applied to be a model, done an Info Session, had their first Solo shoot booked and shot, perhaps some other Solo shoots shot, been asked about appearing in a Video Masturbation shoot, and asked to check this FAQ out.
Consider that the “other” model is what you are to her! 🙃
