Sibling Link

In a few transformation stories, siblings have been an interesting cause of transformation. Now a sibling using a device or spell doesn’t fall under this. Instead sibling link is when two siblings can will physical changes on one another.

Typically these siblings are brother and sister, but that is not always the case. The abilities are usually used to change the siblings into their opposite gender. The range of the ability can vary with the siblings needing to be within eye sight of one another or from long distances.

When a change is done from a long distance it is usually when one of the siblings is in a public place. While the other is absently thinking about what to turn their sibling into next.

In rare occasions this is paired with **** stories where the siblings new identities date.
