Sianne and Rylah are dragon twins that own and maintain a massage parlor in one of wayfarer's many towns. They've taken on an anthromorphic form, so as not to frighten the locals (and so that they'll be able to actually massage folks).
They started their parlor mainly due to their curiosities about the human (and other races) body, and their little intricacies.
The two are known as very intimate and skilled massage therapists, seeming to know exactly the right techniques to soothe an aching body.
The two aren't known for giving sexual favors to their customers, much to the displeasure of some of their guests. The confusion comes from the fact that they both work, and walk around, completely naked - though their abilities allow them to hide their naughties. they don't see it as odd at all - especially since their customers are expected to be nude at the time of the massage.
Sianne is the thinner one, and Ryleh is the one with a pear shape.

They're both about the same in personality, though each with their own little quirks.
Ryleh prepares the oil they use in their massages.
