It depends on the setting. What if it was Daybreaker sealing a defeated, rebellious Dragon Lord in one of these with her fire https://files.catbox.moe/yifvt2.png ? A sort of mocking punishment fitting with the custom among dragons, where she would become a nameless, faceless personal guard.
Or if things went the Greek stories route, dressed her in some sort of Minotaur-like armor, and exiled the ashamed dragon to a maze where she would have a treasure to guard until the end of her days, or until her mistress felt like redeeming her.

Not that Im against the masturbation idea, but a pre-escape days scene where she's getting anally plowed by a tribe member would be a really hot option.
Have her collar chained to a ground post (where she probably escaped from), and show a "seen from below" shot where the ramming cock, her nipples and genitals would be fully visible during the action https://derpibooru.org/images/23063.

Oh and as for her nipples, what do you think of this piercing idea >>42227033 ?
