"We all know who the Rainbooms are. They're the seven girls at school who not only formed a pretty awesome band, but, more importantly, they all have magic super powers that they use to fight magic evils. But what if they used their powers for... something else?"

This story is exactly what it sounds like. It's a collection of separate first-person stories where each of the human 7 use their Equestrian magic for sex. Each story is told from the perspective of a nameless man. Basically, you can choose whether or not you want to read these chapters as self-insert stories or not.

Out of the seven chapters in this collection, five of them are nothing but shameless porn.
For the other two chapters, I accidentally wrote in some actual story, scenery, emotional drama, and romance (hence the "Romance" tag) before the sex happens.

Really, there are only three things that these stories all have in common:

1. Every character is over the age of 18.
2. Every chapter is implied to take place a couple months into an already existing relationship.
3. Every chapter contains magically-enhanced sex.
