Twilight is searching for something new. An adventure she's never done before. Luckily, she finds it. Now, she's ready to travel back to the past. Why waste the opportunity to fuck yourself while you're there?

The main tags are foalcon, futanari, and non-con. Also, Twilight's a bit OOC, if that's worthy of a mention.
The more minor tags are incest play and minor slutification.
