Actually, I don't know if I even want her to have one. That's why I put it in optionally. I envision her to be, you know, a true dog to her owner, loyal and helpful, utterly submissive. So while a cock would not really work when she is just a pet, it could work if the owner wants her to break others.<br/><br/>That's why I haven't really made up my mind... maybe a cock that can grow on command, with a chemical solution? maybe an apparatus inside her that controls it?
