What to do when birth rates of your country are plummetting to the ground at breakneck speed and at the same time your own sex life has become way too stale after a thousand years of life? Celestia seems to have found the perfect answer: revive an ancient sex cult, set a cute big-dicked colt as its leader and dive headfirst into the carnality that ensues. Have the whole kingdom watch and participate in your debauchery too. Why not? Not like anyone can object, you are the Princess after all.

Chapter 1: sexposition, large cock worship.
Chapter 2: semi-consensual cuckolding, coerced male bisexuality, penis envy, large cock worship, lots of nastiness, lots of cum, impregnation.
Chapter 3.1: quite literal cock worship, sex cult ritual, public sex, m/f, lots of cum.
Chapter 3.2: public sex, m/f, m/m, sissy stallions worshipping a huge cock, lots of cum, cum eating.

Also, I'm accepting commissions.
