I Can't Believe I'm an M!

After saving another world, I returned to my original body, only to find the empire's mad dog, Lexion, transformed into a tempting pervert, demanding that he spank my butt. I was trembling in fear of this man, who looked angry enough to wring my neck at any moment, when a system message, which I thought I'd never see again, suddenly appeared: [System Message] A Destiny Quest has begun. Receive a spank from Destiny (0/100)?! My doubts were short-lived. My body, which had changed due to my soul being swapped, reacted sensitively to Lexion's touch, and Nadia, who had never even held a man's hand, unwillingly found herself spending days where her very bones and flesh burned. A life that felt genuinely M, not just M-like, but truly M. "I'm an M?!"
