Body Swap of a Nerdy Girl and A Princess Reborn in Another World: Kiss Me Until I'm Wet Inside...

I'm a nerd and a habitual masturbator. One day, I switched places with a princess from another world!! I'll play the role of princess to the best of my ability so as not to cause her any trouble until I return to my own body! Or so I tried... But we have sex on the night of our engagement party!? On top of that, this lovely and perfect looking prince... is a complete sadist at night... I'm a complete pervert, so with his sweet verbal play and the sexy orders, I get soaking wet and reaches my climax...! He even gives a reward to my throbbing you-know-what like it wants... and I don't think I can resist!
