extreme beastiality

My wife is away on business. I have been bugging her to get me to get me to do kinky things in her absence. She has been reluctant until now. Just half an hour ago, she called me with some "orders". I will do these as soon as it is dark, in about an hour or so.

We live in an old part of town, so there are neighbours on all sides. Fortunately, our yard has lots of vegetation, so it is difficult, but not impossible for our neighbors to see into our yard at night.

Her instructions were pretty short, as she wants to use them as a source of inspiration. All she wants is for me to go to the yard naked with some carrots, a large cooked sausage, and our dog. No instructions about what to do beyond that, but I'm pretty sure I know what she wants me to do. So, my plan is to get on my hands and need in the middle of the yard and fuck myself with the carrot. Once I've done that for a few minutes, I'll insert the sausage. Then, I'll let the dog eat the sausage out of my ass. Hopefully, he'll lick my ass once the sausage is gone. He is fixed, so he will not try to mount me. I've never done anything of the sort before, though I have walked around our yard naked at night before. I'd hate for someone to see me, but I'm pretty sure everybody will be watching the July 4th fireworks while I'm out.

It's almost dark enough to go now. I'll wait a little bit longer before heading out, so I have time for some recommendations before I head out. Can anyone suggest anything else to do? I want to surprise my wife with my exploits.
