I’m obsessed with doggy position

I am obsessed with being in a constant state of ready doggy style position. When my bf is at work I try to get home 10 minutes earlier than him so I can freshen up my asshole and pussy. I will sit on the bed for hours in that ready position with my shoulders holding my body weight as I pull apart my ass cheeks for him to see as soon as he walks through the door. Also I need constant stimulation to my asshole while I’m fucking. He needs to either be rubbing my shit out or fingering my asshole at all times while also busting my shit wide open
