The best anal lube for me is a combination of Vaseline and Astroglide. I use a tube of Vaseline and squirt a shot in my ass. I use my finger to swirl it around inside. Vaseline does a great job coating the insides which keeps the water-based Astroglide from being absorbed and getting sticky. My BF uses the Astroglide on himself and never do we have to keep adding lube to keep things slippery. This trick always works.
Good ol' silivia for us, I love touching and fingering her ass in preparation for my cock and love tasting her musky scent.
vaseline can eat away at your condom but it's fine if you're not using condoms. If you do use condoms, you have to use water based stuff or at least something that won't weaken the condom.
Get down and give her a good rimming first and use the fingers to stretch her ring, once shes relaxed plain old spit should be enough otherwise theres plenty of flavoured gels out there, shop around.:sunny:
The trouble with saliva, is whilst it works very nicely at first, it doesn't last. Unless you like to be done in 5 minutes it isn't very practical.
I dont tend to pump away for long periods, i go down come up then go down and so on, just fucking like a steam engine for hours on end isnt for me, i'm a taste and smell kinda guy :devil:
I would try a high heat resistant industrial grade lube. You want something with strong chemical bonds that will not break down under high temps from fast moving parts
