My first time posting here, hope you guys like it. I probably made some mistakes with the tagging, so please point them out so I won't make the same mistake next time.
Ver a: a humanoid, normal abdomen. Ver b: real abdomen, which is in fact her mouth. Ver c: tentacles. Ver d: shemale version, with a baby Void spawn wriggling out of her urethra.
Just in case you a Westerner - all non-3D art of pornographic nature and Western origin goes to "Western" category. There are tags "Western imageset" and "Western CG" to denote the particular gallery type.
