A Niece and Her Uncle

I have been in the mood for some uncle x niece action, with a bit of a twist. I have two possible scenarios, but they aren't that different.

1. Basically, a family that has been completely fine with incest and encourages it, is looking to wed off my young teen character with a much older man- and that man just so happens to be her uncle. She is going to be married to her uncle, she will carry her uncle's child, she will be her uncle's fuck toy. But another thing I wanted to incorporate would be that after the marriage, the uncle would drug her into a deep sleep, and fuck her repeatedly.

2. That scenario, just without the marriage part. A niece goes to spend time with her uncle, gets drugged, and fucked multiple times.

I was inspired for these ideas because of having a certain read.
