I sucked cock in my late teens, in the 70's, stopped after getting pussy regularly. Fast forward to the early 80s, sucked 3-4 over that decade. Divorced and remarried, after a few years, we started swinging a bit, mostly mfm. One of our 1st mfm's the first fuck, after he filled and rolled off my wife, she climbed on my face and fed me. That surprised me, lol.
The next day, they were fucking, wife was riding him reverse cowgirl, on the couch. I got down on the floor to video 'up close'. The sight of his cock going in and out of my wife, her pussy spread wide, looked like the perfect time to try fucklicking. I did - tasty fun! Didn't take long, and he was short-stroking, and shoving his cock in my mouth. Happened maybe 7-8 times. For the most part, I just re-inserted him back in my wife, but I'd be lying if i said I didn't let his cock 'linger' in my mouth for a bit before re-inserting him back in her pussy.
That he had a impressive cock didn't hurt my feelings either - maybe 7 inches, thick, and the head looked like a small apple - it was a mouthful for me by itself, lol. Still don't know how my wife deep throated him - with glee, I might add. He was her favorite fuck.
Since then, we've sucked some cock together, and I have alone. Cock, great fun! screen shot is from the fucklicking session
