well thats a tough one as so many different senarios involving oral including 1st 6some few weeks ago watching my partner giving oral to the 2 other male partners, one being a regular play friend, him even making her suck our new friends cock deep in between sucking him while the other 2 girls were sharing my cock,

but if i had to pick one it would be our 1st foray into swinging!

we were sitting on lounge side by side after a little bit of playing,with the male half of our our new friends with the opposite partners on their knees and seeing my hot girl taking another mans cock in her mouth was such a turn on more than i ever could imagine!

Talking about it over time was one thing but actually seeing it happening was so much that i could feel my pending orgasm building and our friend suddenly comments "oh by the way she loves to swallow"

well what can i say, with the vision of my girl with mouthfull of cock moaning and watching me getting blown was all i could take and i exploded in her mouth and as she kept hungrily sucking my cock i said oh she loves to swallow too which i think seeing his hot wife taken me in her mouth must have been too much for him too and he proceeded to cum, which turned me on even more.

no need to say it was a long night!
