Always wonder why some of yu guys have a twin fetish.  I don't.  Why not have a blonde and an asian instead?

I am a twin and that would just never happen.
Most doubles are about everyone playin together and most of the ladies that par take are bi, thats incest you are fantasizing about if you are looking for the girl on girl thing/ So seeing as I am a twin, I would never do such a thing with my sister.
I know there are the girls who r twins who do this but I don't get it personally. The sister thing in general is too complex to deal with all in itself. Maybe thats just me.

I prefer the mother-daughter routine myself!

Nothing like a sexy MILF and her daughter to get me going!! It proves you can indeed have it both ways!
