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?!'
