After falling from the dragon, your younger brother Anis needed a long recovery and you decided to take a desperate, but most effective step - to give him your blood.
Your family has dragon blood, which is capable of curing the same descendants of dragons, in the books very little was written about this and many pages were pulled out as if on purpose
Anis, although not immediately, agreed to this, and gently bit the skin on your neck with his fangs. And at one moment you were paralyzed. His first sip and the beat of your own heart in chest, dispersing excitement throughout your entire body
No one ever talked about the feelings that dragon blood caused, as if it was something sinful, but now all you felt was a wild excitement from the way your brother just sank his teeth into you
