I guess I don't mind one way or the other. Normally, she's got one hand on the base unless she can take it all in. So, when she's off for a breath she can give a stroke or two. And I like it when she pulls off to lick the tip or along my shaft and she holds it. I do love watching a cock disappear into a girls mouth...with or without hands!
I prefer no hands. For both giving & receiving. My 1st bf taught me how to suck cock & to swallow his cum & to use no hands, only my mouth on his cock.
