... rapid pace of humping as my rectal muscles slowly began to relax. I could feel my asshole open up and accept his size. The pain turned to pleasure as he rapidly stroked in and out of me, just as he had done when he fucked my pussy. I reached back and found my vacant cunt and smeared my juices on to his shaft to help with the lubrication. I then frantically rubbed my clit. I wanted to cum before he did so I could concentrate on his orgasm when it arrived. In no time, I got myself off with my fingers, and had a breathtaking orgasm. Spirit never slowed down and kept pounding away during and after I had climaxed. But my orgasm was not important. I was here to give him his last one.

My rectum had finally relaxed enough for me to comfortably tolerate Spirit’s cock in my ass. I knew he was getting close to finishing. I began to feel soft spurts of jizz as he unloaded into my bowels. It was a tighter fit there, so it was even more sensitive. I was in bliss. He was filling me with doggie cum. My bliss soon turned to panic as I felt him try to shove his knot into my relaxed asshole. I started squirming, and yelling at him to stop, but it was no use. He continued and soon buried his knot in my butt. I was in pain and could not move. I could feel his cock pulsing in my ass and with each pulse of his organ, more sperm was being injected into me.

Eventually he was played out from his exertion and rested his head on my shoulder. Now, all I could do was wait for his knot to deflate.

I lost track of the time and don’t know how long it took before Spirit pulled out of me. When he did, it sounded like a cork coming out of a bottle. I had one last bit of debauchery yet to perform on Spirit before the night was over. After he pulled out of my ass, I flipped over on my back and scooched under him. I positioned my mouth in front of his huge dick and lovlngly began to suck it clean. The taste was pleasant considering it just came out of my ass, so I guess the doggie cum must mask any other taste. Spirit obediently stood still as I licked and sucked him. It was my last act of servitude to this wonderful K9 lover. I can’t believe this is our last time together. I will miss him. I finished cleaning his cock with my mouth and got up. I did not rinse off, on purpose. I stayed naked and drove home. I quietly crawled into bed, still dirty and naked, and snuggled against my husband. I was hoping he would detect a new aroma on me when he woke up. I was ready to share my deviant behavior with my husband to see if it re-kindled his sexual interests. I can ...
