He'd never told anyone, but he'd always been a bit afraid of Kestrel. This was a secret he'd never dared admit. As an alpha, the idea of fearing one's own mate was deeply shameful.
He dared not tell anyone, especially not Kestrel, that every time Kestrel performed a psychic grooming on him, he was so frightened that his legs would buckle.
Kestrel, she had a large and terrifying psychic incarnation, and despite knowing her for many years, Tarian still hadn't fully understood it.
Every time those massive beings, like monstrous creatures, appeared, they'd impatiently enter his psychic landscapes. They would sweep across the space, effortlessly eradicating all the filth. They were a violent, potent, efficient, and aggressive psychic grooming that ended almost instantly. Then it would depart coldly, leaving Tarian alone, shaking in fear.
Also, Kestrel and Tarian only ever had the most basic, therapeutic psychic grooming. They never had a deeper connection.
