Thoughts?
Bob has a sister (Betty). Betty has a lesbian wife (Joan). Joan is thus Bob's sister-in-law.
Joan is Bi, Betty is lesbian, has fetish for Bob's cock.
Joan has two children (Molly and Polly).
Bob deals with Molly and Polly - so is this incest, presuming Molly and Polly are old enough.
Has Betty adopted Molly and Polly as her own children? Or, and this is where it gets odd from a legal, versus a societal perspective - did Joan get pregnant (from Joan's brother, John) before or AFTER she and Betty married?
If Betty married Joan, with Molly and Polly already around as babies or little kids, and did NOT adopt them, then they are step-nieces.
If Betty married Joan, with Molly and Polly already around as babies or little kids, and DID adopt them, then they are nieces.
If Betty married Joan, and THEN Molly and Polly came into being, then they are nieces.
Now, pick your state of residence.
Maine - Persons known to be within the 2nd degree of consanguinity
Maryland - Persons who may not marry, within 3 degrees of lineal consanguinity or 1 degree of collateral consanguinity
Arkansas - The person committing the act being at least 16 years of age, knowingly, and without regard to legitimacy, including blood relationships:
An ancestor or a descendant;
A stepchild or adopted child;
A brother or sister of the whole or half blood;
An uncle, aunt, nephew, or niece; or
A stepgrandchild or adopted grandchild.
Pennsylvania - Ancestor or descendant, a brother or sister of whole or half-blood, or an uncle, aunt, nephew, or niece of whole blood (blood relationships without regard to legitimacy, and relationship of parent and child by adoption).
Texas - Person known to be ancestor or descendant by blood or adoption; current or former stepchild or stepparent; parent's brother or sister of the whole or half blood; brother or sister of the whole or half blood or by adoption; children of the actor's brother or sister of the whole or half blood or by adoption; the son or daughter of the actor's aunt or uncle of the whole or half blood or by adoption.
From a legal perspective, if
The reason I went into all of these different states, as well as the three different scenarios, is simple. Pretty much, if Betty has NOT adopted Molly and Polly, then Bob can bang Molly and Polly and it's NOT incest, either legally or morally.
If Betty HAS adopted Molly and Polly, or Betty and Joan were married and then Joan popped out Molly and Polly, then Bob IS committing incest by banging Molly and Polly.
Now, more fun is what acts could Bob do with Molly and Polly? In some states, physical penetration of the vagina is what's against the law, but oral is not. In others, it's both.
And then there's Rhode Island.
No person shall marry his or her sibling, parent, grandparent, child, grandchild, stepparent, grandparents' spouse, spouse's child, spouse's grandchild, sibling's child or parent's sibling.
Consensual incest between people 16 years old or more is not a criminal offense.
Bang away, Bob, bang away! (In Rhode Island, anyway.)
