Granted!

You are now the last born daughter of a mighty, and milfy dragon! Now we'll past her reproductive prime, and with all your sisters having flown the hoard, she entrusts all her collection of gold amd riches to you, to become completely yours in the event of her passing. Though that won't be for another few hundred years in the least, in the meantime, the both of you effectively share everything you own.
Gold is a simple matter, you're free enough now to not need to ask to spend it anymore.
Food and space are similar, you won't really be tripping over eachother often, it is after all, a VERY big hoard.
But, a good time, is a comparatively limited resource for the both of you...
You're old enough to be an adult, but still falling short of both complete sexual maturity and the practical knowledge of how to best attract a partner. Think, freshly 18 but that's gonna the next couple dozen decades.
Your old lady on the other hand, certainly has all the knowledge, but has undeniably lost the body to keep up with that kind of lifestyle anymore.
Leaving the both of you, up quite the hot and steamy creek, without much in the way of paddling towards what you really want individually.
But collaboratively, it'll be a lot easier to pull for people wanting the family package. Meaning, while you might make a catch easy enough, you'll have to play up the mother-daughter bond to keep them, from kissing casually and not so casually, even playing with eachother at their request occasionally, though doing so naturally is very much what's anticipated...

Here's the kicker though...
Incest is a pretty big usually untrue stereotype towards female dragons.
That a mother gets too attached to let them go, that a daughter might cherish a parent too much to leave her behind...
And while you and your mother insist to eachother, this is just a plot to sate your heat cycles, you both
are running into them more than should be usual at either age...
