I had an older gentleman who was in his 70's. Full dentures and was a horny fucker. He would host me Friday afternoon through Sunday morning, and we would spend the entire time naked/hanging out and having sex. One of his specialties was removing his dentures and giving me the best gumjob this side of the Mississippi. From never experiencing the feeling of gums on my shaft to the eagerness he had while sucking cock, I can say that it need to be experienced at least once by every guy. The feeling is much like a normal blowjob, with the absence of teeth he is able to actually close his mouth around the cock, getting a better suction. The first time he sucked me I came within the first 2 minutes. Felt that good. I always had at least 3 hard-ons before I went limp and took a break.
