Thanatos stepped towards the young woman when she came, watching the way her body reacted to the ordeal and simply offered a grin-like snarl, nearing her as he approached, reaching his hands down he grabbed either side of her head, grinning as he jerked her head back, nothing too violent, but enough to bring her eyes up to his, "And you, child, who gave you permission to come this evening?"
One hand left her head, sliding down over the front of her throat, and then towards her breasts, squeezing the left as he kneaded into the flesh with strong, rough fingers. Staring down at her eyes, his cock brushing against her face as he slid himself closer to her, simply watching her before grabbing the base of his cock to pull it free of her face.
"And my name is Master to you, not Thanatos. You are not permitted to use my name, out loud, even in private," He then grabbed her tit, twisting the nipple rather hard as he stared down at her, "What's your excuse now?"
