what is your favorite lube for a2m

My husband and I have been crazy about our new kink - a2m. When we do it, it makes the sex sooo hot and nasty - we love it! ;)

After buying some flavored lubes here (love the Pina colada from Durex) we also started experimenting with other fun flavorings. One of our favorites at the moment is simply a canned whipped cream - squirt a bit in there and it makes your ass taste so sweet! :)

I was wondering what is your experience / preference?

P.S: I must admit that I also love a2m with no flavoring - just the spit and my ass juice (always douched and thoroughly cleands)... not much of a particular taste (still better than pussy), but if feels so kinky and nasty! hot, hot, hot! ;)
