"I understand now..." Marcus said, slowly approaching the demoness.
Michelle approached Marcus, and closed her eyes as she moved in to kiss him. Before she could begin the foreplay, a severe blow was dealt to her forehead... Marcus delivered a headbutt whilst her eyes were closed!
"One must willingly submit to you in order for you to have any power over the mind," Marcus explained, "Now, beast, I will put an end to this."
Michelle was speechless; she stood back up, and readied her claws, "I don't know how you managed to defy me, but it does not matter, my strength far exceeds that of any human! If I cannot shatter your will, I will simply break your body!"
The dark lady took a few steps back, then flew straight towards Marcus, and attempted to dig her claws into his torso. She managed to draw blood, but the blow wasn't as effective as she had expected; her talons didn't even managed to go a quarter of an inch into him. As she simply stared in confusion, Marcus punched her in the face, knocking her down a flight of stairs.
"How... You shouldn't even be standing!" Michelle rose once again.
"You said it yourself; your powers cannot effect a child."

"Yes; you could only tempt me once I had been given the choice of how to live my life. However, you made the fatal mistake of assuming that I would choose a life of lust, desire, and greed," Marcus explained, "I am indeed but a mortal, but my life is sworn to hunting your kind; I have chosen to devote my life to eradicating all the dark forces of this world, your kind first and foremost. I am a paladin, and your terror will not see the sunrise!"
Marcus jumped from atop the stairs, his fist glowing with a holy aura, aiming for Michelle's face once more. She narrowly rolled out of the way, but was slightly singed by the aura nonetheless, causing her to hiss in pain.
"This isn't over; you will be mine, one way or another," Michelle said as she flew towards a window, "I grow stronger with each soul I take, and sooner or later, my power will be more than a match for yours!"
With that, the succubus shattered the glass behind her, and raced into the skies. Marcus sought to pursue her, "But first, I should probably find some clothes..."
