Asshole Play

I was fooling around in bed with the wife, when she rolled over. She does this when feeling submissive. She knows I'm going to play with her asshole. She doesn't say anything she just sticks her ass out, and let's me do what I want. I lifted her butt and slid my hand between her ass, her pussy was so wet, I just used that to lube my fingers. Then I started rubbing her asshole. I slowly wiggled my middle finger into her hole. I could feel her pressing her ass against my finger. I slid up to the first joint of my middle finger. Not too deep. Just deep enough to drive her wild. I kept up the pressure and movements in her little hole, and just kept digging her ass. It was so hot how much she liked it. When she had her fill, and rolled back over I was so aroused. I pinned her arm down above her head and buried my face into her armpit and kissed and licked. I have a kink for armpits now that I never used to have, I've had been wanting to do that. I think she liked it. I'm going to request she doesn't wear deodorant next time. There was some stubble that turned me on even more. I feel like as I get older I want filthy things even more. I loved how my fingers smelled afterwords. Next time I want to fuck her ass with my tongue.
