The best blowjob i ever had was from an older guy about 67, no teeth. Let me tell you it's like a woman with a large pussy except his mouth and throat could grab your cock and squeeze in rhythm.Nothing better,
and my cock is 7 3/4x5 3/4, it was like 4 inches to him.
He probably could've taken 10 with ease. i asked him, he became my regular stop.
He told me that he used to suck a mwm with 12x7 1/2. He told me that there used to be a lot more guys with really big cocks around than there are now.
He also told me he sucked cock when he was in his teens, but got more cock, all of it married men since he was 60 than any other time in his life.
I never suck a man that sucks me, well I have twice but stopped. So he has been the measurement for my skills.
I believe when I deepthroat, a man would never know I had any teeth, not matter what his size is.
So no teeth is nice, but sucking like you don't have any teeth is even better in my opinion.
