I always thought they looked like sisters, and wanted to see them in a scene together but not like this. Less mobility.
There's nothing a guy can do with Siamese twins that he can't do with two regular girls. If anything, it limits the threesome moves. You can't even stack Siamese twins. Maybe it would be a fun novelty to jizz on the conjoining skin mass. Yes, I've put some thought into this.
Oh jeez it's not even b/g sex? Blaaaah.
