The most important thing for me is not just suction, but focusing that suction entirely on the egde of the lips. You can use the whole mouth to do that, but that just speeds along the process, and I want it prolonged and intense in one area!

I think the most important sensation is the lower lip on the underside of the shaft. Outside of that, I like a vocal girl, someone who is actually turned on by doing it, someone who doesn't mind when I take charge of it with a grip on the back of her head, balling her hair into my fist...

Pulling out of her mouth and making her take long licks across the length, with the lights on and in the living room, is great fun.
