Absolutely! The nibbling of the gums (minus teeth) is enough to produce even the hardest dick to get more elongated and enlarged.
I had this guy who discretely removed his full dentures (uppers and lowers), put them in a special box and slip them in his jacket pocket, before taking my dick to receive his educated talents. In a few days I had the opportunity to get him the second time, which I enjoyed just as much as the first. --Two of the best cock suckings I've ever been privileged to receive.
