OP, wattchewant's tumblr is still up they just have not updated in months. You can still get the models from there. You may have to subscribe to some models on steam workshop if textures arent working for you. There is also one Warframe model on sfmlab and that one has pussy controls. The one on watts site done have pussy/anus meshes or even textures so you will have to figure out something for those.
