Even though the School of Friendship was an academic establishment meant to educate the youth of Equestria and beyond, Headmare Twilight decided to allow for night classes to be held at the school for Ponyville's adults. But while most of the attendees and volunteers gave courses on various skills on the lower levels, the promiscuous Spike was able to host his own class on one of the higher floors. And since his reputation as a slut was well-renowned throughout Ponyville, a good number of ponies decided to attend and learn from the best.

And fortunately for the class, Spike had a little surprise in store for the mares and stallions who showed up: A very unexpected, but also much appreciated volunteer to help aid in the dragon's lessons. Big Macintosh may have been a newly-married stallion, but he and his wife Sugar Belle understood the importance of safe sex enough to trust Spike's intuition, and give the classroom a lesson they'll never forget.
