Bai Zemin was keeping track of the time he had left mentally, by the time about 40 minutes of the initial 60 minutes had passed, he finally put Lilith's legs down and adjusted his body so that he was almost completely lying down on the bed.
With her wrists still bound and her hands above her head, Lilith looked down obediently and watched wide-eyed as Bai Zemin planted delicate kisses on both legs, slowly moving higher and higher in tune with the sound of the sheets beneath their bodies accompanying their movements.
She didn't even notice that when he approached her crotch area, slowly kissing her thighs, she spread her legs even wider as if inviting him in.
