sexual object

I'd like to find my girl naked on the bed, when I come back from work in my elegant dress.
But not waiting in a simple position.
Naked, in a doggy-style position with all her ass already spread for me. Just waiting for my finger and my tongue.
Not a single word, not a sign. Just in perfect silence.
I'd like to push my tongue in her butthole and treat her ass like a sexual object, a place to explore with all my desire, all my curiosity...
