more textured inserts

[vinylmaster13]

Hi , this is something I have been thinking about , Why not something more evil ?, I mean , a more textured insert for the dolls , perhaps this is something personal , but I feel the factory's insert a bit soft , . Has anyone tried other inserts? ( maybe from other dolls , I have seen a fleshlight used in a doll as insert , but I do not like (again ) the feeling , It is soft (I have had some of them)) . I have been thinking about using a soldering iron for making a different texture to the the doll's insert , but maybe I would damage it forever , so I am a bit scared abut that idea .... If you have any other idea I would thank you . Beerssss
