Who's girlfriend?

[bigsteve]

I'd like to start a thread about my girlfriend and my sister. The basic plot would be that my girlfriend has been seeing my sister, unbeknownst to the both of us. My sister isn't aware of my girlfriend and I'm not aware of her's. Eventually the plot runs to a point where our mutual girlfriend tells us each about it privately in hopes that she could fuck us both, not knowing the can of worms she might unleash.

I'll be playing the role of the boyfriend/brother.

Any females interested in playing should please PM me.

I'll re-edit this post once we have a cast. Please only PM me if you want to play, it avoids clutter in the thread.

Thanks,
bigsteve
