A scenario in which Norael is horny, a little drunk, and frustrated.
This frustration comes from being bad at conveying her emotions, so often those emotions bottle up inside her to explode later, at inopportune times and places. She struggles with telling Gullin what she thinks and feels. When she wants affection or sex, she's not really up front about it, beating around the bush if you will.
Gullin though is often good at reading Nor. He's spent a lot of time with her and has come to sense when she's emitting more of a 'romantic' aura than not. She'll give him more inches than she typically would, allowing him closer, letting his touches linger, even staring back into his eyes. He did like to watch the shimmer of lights reflect on her aqua blue scales, it reminded him of the ocean as he'd tell her very often.
It's earnest talk like this from a simple boy that would end up going far with Norael, or perhaps she just has enough of his nonsense and likes to shut him up by shoving him mouth-first into her breast.
