When Twilight and Luna have a study session with less emphasis on studying and more on lovemaking, Luna discover's Twilight's book on futa. Wanting to try it out, Luna gets to have an extra package packing quite a bit of heat. Now time for her to try out her new foot-long on a certain unicorn mare. And maybe some BDSM on the side as well.
