Yes: her mouth!

My cock already erect again, I take Brynhild's chin, press her cheeks to maintain her mouth open, and force my way into it. I come and go several times, making her choke, then release her chin and let her adapt her mouth to my member and its moves. She begins to answer them, using her lips in rhythm, and working her tongue with a dexterity which makes me think that her barbaric husband was familiar with this exercise - and probably very satisfied with it.
She swallows the first squirt before I finally get out of her mouth and plaster her face. She stares at me, panting, her noble face of fallen queen crossed by trails of sperm.
"Do you know, Master, that if you had done this to me but yesterday, or if Valerianus had dared this on me, you would now be obliged to crouch before peeing?"
"I'm happy to see that you now understand where are your duty, your interest... and your pleasure."
"Is it what Rome has made of my daughter, Master?" she continues with a dreamy haze in her eyes. "Is she now, too, wherever she can be, an obedient slave taking pleasure in her submission?"
