A possible scenario of a relative whom is an aunt and a sister at the same time; when a woman has a child with a father and another with his son, or when a man produces children with a mother and a daughter, the aunster being the result of Subject A and the older generation (child with the mother or father) as related to the other child.

When one's sibling has a daughter with their parent, the child becomes their niester; a niece because they're their sibling's daughter, and a sister being their parent's daughter, making her a niester.
My niester Ruby is so hot, I just might have to date her and take her to prom this year.
The male child of your bruncle or aunster. Your bruncle/aunster is the result of one of your parents having a child with any of your grandparents, and the son of your bruncle or aunster would be your couphew; your brother or sister's son is your nephew, and your aunt or uncle's son is your son, making the end result your couphew.
My couphews Tommy and Dylan are so adorable when they swing on the swingset, my bruncle Stewart must be so proud of his two sons.
A bunch of people who hate each other and eat dinner together.

The way the British royal family keeps itself German.
It is illegal for any member of the British family to marry anyone who isn't a blood relative. (Thanks to the 'Royal marriage act' of 1716) Even lady diana

The female child of your bruncle/aunster. Your bruncle and/or aunster is your aunt/uncle and sibling at the same time, so their children, in this case the female, is your niesin; your sibling's daughter being your niece, and your aunt/uncle's daughter being your cousin. Therefore the end result is biologically your niesin.
My niesin Sally is such a cutie pie, she's my niece and my cousin at the same time.
