Rain was indeed a professional and someone fit to be Arya's secretary.
Even under immense pressure, she retained her professional look and didn't fluster much.
Initially she was struggling to answer, but after she got in the work mode, her whole aura changed and she didn't seem as flustered anymore.
In due time, she was answering everything perfectly and this made Arya proud.
She turned back to look at her husband and put out a smug look, expressing, 'Do you see that?'
Lith smiled and responded back by thrusting his shaft deeper into her pussy, hitting her cervix and making her moan.
Arya eventually felt her orgasm come close and squeezed Lith's thighs, hinting to go slow.
Shaking orgasms were reserved for Lith solely. She didn't want Rain to see her vulnerable moment like this. It was an important thing a mighty ruler like Arya had to take into consideration.
