Kind of off topic, but there’s a new show on Fox called Arrested Development and they are always talking about how the male kid has a crush on his cousin. It’s his first cousin. That strikes me as an odd thing to have on a tv show, but then it’s kind of an odd show.
I had sex with my brother-in-law’s sibling.
BwanaBob, that might have been based on a true story, but in reality the couple had children and were actually imprisoned (at least the father, don’t remember about the mother).
“I was fourteen years old when we went on holiday with my Uncle Frank and his daughters. Sixteen. Twins. Blonde. Now I knew that Sarah fancied me, but I wasn’t too sure about Alice. Anyway, middle of the night, I wake up with this tongue stuck down my throat. Wide awake now - I couldn’t believe my eyes. It was Uncle Frank! He’d got the wrong room - he thought I was my mum!”

BwanaBob, that movie was called Close My Eyes and starred Clive Owen (who was also in Croupier)
If I take a step back and look at it objectively… my brother would make a good mate but not because he’s completely hot (though he isn’t that bad looking by today’s standards). I’d go out with him because he’s everything my boyfriends have never been… faithful… honest… heck he’s been dating one girl for almost 2 years my longest relationship is just over a month sighs
But no, my brother shudders no way! That’s just too gross…
My uncle on the other hand… (hey I like Surfer dudes!) but A he’s my UNCLE B he’s married with two kids and happy in Australia…
Not terribly relevant, but legion’s quote instantly made me think of this
Hey Doc,
you just as might as well have said that you had sex with your brother-in-law’s accountant
Freudian typo?
Doctor Jackson was joking I think.
I never had improper thoughts about my sister. Maybe its because I grew up with her, through being little kids, though teenage years etc. We built a bond of love based on being family, and its very difficult for sexual feelings to creep in. Just a guess.
Do I score (no pun intended) extra points since my brother is thinking of becoming a priest?
Anyway, in answer to the question at hand:
Nope. No way. Uh-uh. Ew.
I hate to belabor the obvious, but since the responses have been unclear: There’s a reasonable chance that Doctor Jackson’s brother-in-law’s sibling is the good Doctor’s wife. Just a wild guess and all. 
Thanks snorlax but that’s not the movie. I’ve seen Close My Eyes, it’s also a compelling movie but the story is nothing like the one I described.
I don’t have a sister, but I’ve fantasized before about having a sister and having a relationship with her. I also had a secret crush on my aunt as a young lad, but my idea of romance then was pretty much just chaste kissing.
If I did actually have a sister, I doubt that I’d actually have the fantasy about her, as I’m not particularly close in any way with anyone in my birth family.
Well I know for a fact that I’ll never have feelings for my borther or sister because I DON’T HAVE ANY SIBLINGS!

I didn’t know you went to the University of West Virginia! 
My brother–yuck. No way. The worst thing is, I look just like him. When I look in the mirror it’s “Aaaak!! Steve!!! Oh no, that’s just me again.”
He used to look like Richard Gere, which is why I hate Richard Gere. Now he looks like Jerry Garcia riding a Harley. Kind of scary.
I remember once when I was a teenager my Mom was dating this dude who had a daughter about my age. What they would do on occasion was, he would bring his daughter over, we would have dinner than Mom and the dude would go out for drinks. Things were going pretty well for the both of them (romanticaly) They were even talking about marriage…
That is of course untill one night they came home only to find me and the dudes daughter going at it like a couple of rabid dogs.
So I guess you could say I almost did my step sister.
Sorry Mom.
Man I’ll never forget the look on that guys face… CLASSIC!
and my poor Mom; How do you punish someone for something like that? “DAMMIT SHAKES IF I TOLD ONCE I TOLD YOU A MILLION TIMES; STOP FUCKING YOUR SISTER!”
What, no mention of V. C. Andrews?
