Matt, by doing a favour for your sister's friend you have mixed family and business. My advice would be to take a step back and realize that you made the mistake of not approaching this professionally first be thinking of it as a favour, and second by not having a written contract. Consider it experience gained, move on, and don't make the mistake again. If you make a big deal of this, the only thing you will gain is having photos unceremoniously removed and antagonizing your sister. You can't have it both ways--she is either your sister's friend for whom you do favours, or she is a client who you approach in a professional matter. Blurring these lines leads to situations like this and it is almost impossible to un-blur them later without confusing and angering everyone involved.
