One day Pinkie Pie was sad, and did not want to be sad anymore. She was sad because she was not being kissed often enough, and decided that she would like to have makeouts more often. Specifically with Fluttershy, because Fluttershy had many admirable qualities and would be nice to make out with.
What Pinkie did not know was that another of her friends, Rainbow Dash, was also sad. Rainbow Dash was sad because she knew that Pinkie did not want to make out with her, because she loved Pinkie and thought that making out with her would be pretty great.
Rainbow Dash knew that Pinkie very much wanted to make out with Fluttershy, and had decided that she should help her two friends be happy. She was filled with pain and sadness by this, but because she was a good friend she put her own desire for makeouts aside so that she could help her friends achieve the makeouts they both desired.
Fluttershy, however, did not wish to make out with either Pinkie or Dash - she wished to make out with both Pinkie and Dash simultaneously, as the higher number of ponies would doubtless lead to superior makeouts and also probably because she loved them both or something.
She had not yet achieved her goal of bringing these makeouts about, and was very sad about this. Her inner pain caused her much sadness.
Fluttershy decided that to increase the number of makeouts she was engaging in she needed help, and so she paid a visit to her good friend Rarity. When she told Rarity of her dilemma, the unicorn was saddened because she secretly wished to make out with both Fluttershy and Rainbow Dash herself. But she did not say so, and instead suggested that Fluttershy visit Rainbow Dash and initiate makeouts, because Rainbow Dash would likely be receptive to makeout attempts.
Fluttershy, however, saw Rarity’s hidden desire for makeouts due to being very wise and perceptive. And she suggested that perhaps if Rarity came along, all three ponies could engage in makeouts at the same time. And perhaps, with careful planning, they could later increase that number to four.
Rainbow Dash was very surprised when Fluttershy and Rarity visited and expressed their desire to engage in makeouts, for she had not believed that she was worthy of their affection or their makeouts. Their desire to make out with her made her cry, but they were happy tears, and they led to kisses.
Many kisses.
At that same moment Pinkie Pie, who had been visiting her friend Twilight Sparkle for romantic advice, arrived with her friend Twilight Sparkle in tow. When she saw the pony she wished to make out with making out with ponies that were not her, she was very sad and angry.
Pinkie Pie believed that none of her friends could love her, for she was a silly pony who did not see her own value. Though all four ponies looked for her, it was Twilight Sparkle who found her. Twilight Sparkle was happy to see Pinkie, and listened as the earth pony explained that she felt she was not deserving of makeouts or love, and that this made her sad.
Twilight Sparkle was saddened, but also happy because she knew that she could cheer her friend up. She confessed her own long hidden desire to engage in makeouts with Pinkie Pie, and the fact that she had loved her for a long time, but had surpressed the fact for fear that Pinkie could not work. This had made her very sad, and the sharing of her burden relieved much of her deep inner pain.
Pinkie and Twilight made out for some time, until Twilight Sparkle realised that their friends were probably being made sad with worry. She also realised that their makeouts would be all the more satisfying if they involved five ponies, instead of two. Pinkie Pie smiled, because she liked this idea and it made her happy.
So it was that all five ponies coincidentally met in a clearing a few moments later, despite having not run into one another in the many hours before this. Pinkie explained the reason for her sadness, and the other ponies were sad. But then they were happy, for their shared pain was nullified by the shared desire for makeouts. As they expressed this sentiment, they each grew happier and attempted to initiate makeouts.
But the wise and beautiful Rarity, who had wisely realised that if five of their circle of friends desired to make out with each other then it was possible that they would be able to find one more addition and engage in the longsought - by all of them, though they had not realised - six pony makeouts.
Applejack was not a sad pony. She did not have deep inner pain, though she sometimes felt sad that she was not able to engage in makeouts with her best friend Rarity. She had much to be happy about in life, and was therefore the least sad of all the ponies. But that did not mean that there was no room for her to be happier, and she believed that the way to make it so was to locate Rarity and request make outs.
She was saddened when she discovered that Rarity was not at home, and though she did not have deep inner pain she still came close to tears. Then suddenly her five friends, Twilight Sparkle, Pinkie Pie, Rainbow Dash, Fluttershy and Rarity appeared before her. They expressed that they had been engaging in makeouts, and all wished to make out with her very much.
Applejack considered this and, though she had not thought of anypony but Rarity previously, realised that she did indeed wish to engage in makeouts with all of her friends.
And so the six ponies made out, completely cured of their inner pain and destined to be happy and possess makeouts in abundance forever more.
