I’m an M?

After saving this world and finally returning to my original body… I found out I’d become a pervert who tempted Rexion, the Empire’s rabid dog, by begging him to spank my butt. I’m trembling in fear before an enraged man who looks ready to strangle me at any moment when, all of a sudden, that system message I thought I’d never see again pops up. [System Message] A Fate Quest has begun! Fate: Get spanked (0/100) W-What the…?! I barely have time to question it. While our souls were switched, my body changed… and now it reacts with extreme sensitivity to Rexion’s touch. And me—Nadia—who had never even held a man’s hand in my life… without meaning to, I ended up living days where my skin and bones burn. A truly M kind of life: like I am, like I’m not… but totally M. —Me, an M…? <Me, an M…?>
