I'd do the tall one. ;)

Is there a sale for lawn trashbags at Lowes?

You can get head AND teabag at the same time. Cool.

Ok, this has some serious legal repercussions... what if one wants to have sex but the other doesn't... is the man guilty of rape if he proceeds to have sex with his wife when her sister refuses?

If she has a baby, who is the legal mother????

one set of reproduction organs, so trick question - they both are.
So that means they both feel the pleasure of vaginal sex at the same time.... Hmmmm. Man's best chance to please two girls at the same time

That was going to be my question....which one feels the orgasm, or is it both? Having two chicks screaming out in pleasure would be kind of cool...well except for the uncool part.

Can the other one marry a different guy? Can they both marry the same guy? Will the husband be able to claim them both on his income tax return?

So many questions.

What if one likes anal but the other doesn't?

Yes. This is the best case scenario. LOL.

Nothing like tossed salad and a blow job--at the same time

It would be cooler if they had 4 boobs.

I ask myself how buzzed I've got to be to get past the uncool part and be like F@#K it lets do this!

Imagine how weird it would be for the kid growing up:

"I have two mommies."
"Oh, so your parents are lesbians? Is one of them your biological mom?"
"They both are. I have a daddy too."
"????"

"One set of reproductive organs".

They couldn't just say one vagina or something like that? Would've been all win for the guy if they somehow each had their own vagina. Since they share one, I don't think you could rule any sexual encounters as a true threesome
