Tried it once when I was young, but the taboo of bi/gay was too much, and just got a lick or 2 in before stopping.
In my early 60's, wife was riding a friend, and I was sitting on floor videoing. I thought to give it a try again. So, put the camera on his knee, and leaned in for licking. It was a instant hit with my wife, lol. But with the movement, his cock kept popping out, and shoved in my mouth. I didn't mind a bit, as this was the 1st cock in my mouth in decades, and it was a very nice one too, fat with a big mushroom head. But, I just kept sticking him back in my wife...
The video was great, the first showing me with a cock in my mouth, lol. Sadly, that was our last time with him...
We made another friend, he enjoyed fucklicking. He likes 69 with my wife while I fuck her from behind. When I start to cum, he wants me to pull out, and cum in his mouth. I don't mind - he can really suck cock!
