Now that Shining Armor has been fused with Big Macintosh and Zephyr Breeze to create the first male alicorn in centuries, it's time for them to make it official. Cadance, the stallions, and Sugar Belle must all descend into the Crystal Sanctum to perform the rite of the alicorning. Not much is known about what happens down there, except that it's furnished with hard light holograms that will see to everypony's every need, and that for the ceremony to be considered a success, all the mares who go down must come back up 'heavy with foal'.

Contains: three-headed alicorn stallion, excessive cum, cum inflation, big cock, size difference, treating a hologram mare like a hologram, licking cum off the floor, gangbang, infidelity with permission, impregnation, trace amounts of mare-on-mare, brief stallion-on-stallion kissing, Zephyr being mildly Zephyr.
