lucky puppy. I'm sure simi has all sorts of fun plans for you!
But looking for anal, pee and humiliation as well huh?
Ok. Let's start with a bit of an experiment.
Order some itching powder.
The next time you are refitting your cock cage (I understand this may be a little way off!), pour the itching power inside a condom.
Put the condom on, and rub yourself a bit. Make sure that 'nice' itching powder is spread all over your cock. Snip the tip off the condom so you can still pee, and refit the cage.
...if this works the way I'm told it does, it should leave puppy desperate to hump pretty much anything in the hopes of scratching that itch
