Doing my wife in the ass

my wife let me do her in the ass just 5 times, she dosent like it but I love it, it takes me a lot of begging from me for her to let me stick my cock in her ass, all 5 times I had to wear a condom which was fine, I love how tight & warm it feels & it takes me no time to cum, on night we were out with friends for drinks & I volunteered to be the designated driver, my wife is not a big drinker but that night I kept buying & she got really smashed, well as you know what came next after a struggle getting her into bed as she is not a small woman, the fun part was undressing her down to her pantys & bra, she went out like a light & before you could drop a stick I had her pantys around her knees & her bra was off, I lubed up & was as hard as I have ever been & slipped my cock between her amazing soft but cheeks & just left it in there a few minutes & it was so warm & this time there was no condom, the feeling was amazing with no condom & her having no idea I was deep inside her warm asshole, I started to thrust & blew my warm cum inside her warm tight asshole in about 30 seconds, oh boy it was the most amazing sex I ever had, when I got cleaned off I got her straightened up & I joined her in deep sleep, the next morning I was up & when she finally stirred & stood up she had a frown on her face & looked at me with that puzzled look on her face & kinda knew something happened but didn't say anything, I was smiling inside like a big k**, I cant wait till next time & im sure she might put her guard up & not drink as many shots, I hope you enjoyed my experience!!
