When was the last time you had anal sex?

Got pegged last night. We were sitting on couch, me doing a sudoku and Amanda was reading something. She all of a sudden looked up at me and said upstairs into the room ( we have a play room others would call it a dungeon ) when I got upstairs she had the pillory ready for me. I straddled the base bent over and put my neck and wrists on the lower beam as she pulled down the top beam and locked it closed. I was helpless to whatever she wants. She lifted my satin nighty and removed my diaper and plug and left my ass exposed. I could not see what she was doing behind me but could hear her rustling around, it took her a few minutes but she walked around in front of me wearing her strap on with nothing in the ring. She saw the confusion on my face and said it a secret while pulling hood over my head, no eyeholes only open mouth and very small nostril holes. Now I was getting more excited ( I love wearing hoods ) she bent down and tapped my cage and asked how my sissy clitty was doing trapped behind its flat prison wall. She then asked me if I wanted it all, I said yes mamm as I opened wide and she shoved a gag inside that filled my entire mouth and held my tongue down which makes me drool. ( she knows my desire to be gagged as much as possible, especially when I’m going to be helplessly pegged/fucked ). I can’t see or make a sound and was already starting to leak drool from around gag, next thing I feel is lube being dripped onto lower back and it’s sliding down crack and her hands wiping it all over using fingers to get it everywhere. Still waiting for what’s to happen but not knowing with exactly what. After what seemed forever I feel the tip of something press on my sissy hole. I can tell she is using her hand to support it and get it started. I then feel my hole start to stretch open, the way it opened up and stayed stretched I knew right away she was using my blunt tipped horse cock. Once she got it in and had more control she slowly slid it in without stopping, I clinched down on it the whole time and felt every bit of it, after about 10 or so long slow strokes she pulled out leaving the last 2 inches in me. I wasn’t ready for her to stop yet, my head hung down and I was really drooling now. I could feel more lube being squirted at top of my gaping hole and then all of a sudden she pushed it in all the way, I could feel her pelvis against my ass, there was no more left but she kept pushing, she pulled out and rammed it in me again a few more times before she got into a steady rhythm. Now I was in heaven able to concentrate on the cock sliding in and out of me and did not take long before I was squirting ropes of cum from the tiny hole in my cage. It had been a long time since something like this happened on a whim during the week, not that I was complaining. I asked her what brought that on and she said that she just wanted to do something for me just because. After she unlocked the top beam from my imprisonment I got cleaned up she put new bedtime diaper on me and let me sleep in her bed with her all night. Sorry for the long response to your simple question, I was just running back the events from last night.
