Despite the anger from the misunderstanding of what Rex was about to do, Gistella falls to the temptation and decided to serve him and indulge herself in the pleasure that she had missed.
It's rare for them to get this kind of alone time, and she simply can't waste it.
Not only were Adhara and Evelyn not inside the castle right now, but Rex was also in the mood and don't have anything to do. Even though it leans more toward the fact that he was forced to do nothing, it's essentially the same.
Gistella's eyes were glazed with lust as she lies sideways with her mouth covered.
At this current moment, her sacred place was being stabbed repeatedly by the usurper, softening her inside whilst the alluring moans she lets out were muffled by Rex's big hand that covers her mouth.
It's been quite some time since both of them have done this, their intimate senses were heightened.
