You give her a taste of her own medicine!

Victory and pride overwhelming you, you place your one foot on her mouth lightly "So, beast, how about you show us who's really the mistress here? Kiss my feet!"

You could hear the succubus kissing your feet slowly and reluctantly. Your feet were quite sweaty, but they weren't dirty due to a small cleaning spell you learnt as a priestess. The succubus continued to reluctantly kiss your foot, not putting in effort so you gave her a warning. "If I were you I'd be a bit more enthusiastic than that. I can still hurt you!"

"B-but the pain i-is too much! P-please h-help me! I-I promise to do what ever you s-say afterwards!"

The succubus didn't sound like she was lying. Having a sword impaled into you through your belly must hurt, but you didn't want to let her trick you.
