I would actually like some more dildo poses with women and other shemales. If it where to be handheld toys I would like bullets or some other teasingly good toys, for penetration I would like poses with double ended dildos, strap-ons or feeldoes.
I think the best way to add something like feeldoes would be an option for females to wear them instead of a strap on, butt plugs could be added in a similar way. Though... it would be fun with a pose where the one giving has a remote controlled toy somewhere that the other girl can activate.
I think a fun double ended dildo pose would be one where one of the participants has more control over the dildo than the other, like if one girl is laying on her back and the other positioned so she can move easier.
