Sister's room (messy) (Patreon)

Getting back at home in Canterlot just to grab a few things she'll need for her new place at Poniville, Twilight was told by her parents that the house would be alone fro the weekend so she didn't even bothered to knock the door and she just entered and lurked in, but then she just heard some noises comming from her room. When she peeked in, what she found wasn't anything she expected and by the look on her brother's face, he wasn't expecting anyone to be home that day neither and couldn't come up with a good excuse for what was before her eyes. The only thing in Twilight's mind was that now she had a new sister to play with.
