Edible lube

Sorry if this has been asked before. I love Mrs D giving me a titwank and would like to combine it with some oral. We find the best lube for a titwank to be baby oil but obviously it's not edible. We've tried various water based lubes but they are not as good as baby oil and tend to try out. Does anyone know of any lubes which have the slipperiness of baby oil but are edible?

I havent tried it yet, but intend to....Sliquid Swirl range. All reviews look good and it comes in a few different flavours. Actually LH are running a competition to give away a 5 sets of sliquid swirl lubes...

Sliquid Swirl is great but does try out. http://www.lovehoney.co.uk/sex/lubricants/flavoured-lubes/sliquid/all/all/all/all/

How about flavoured massage oil or candles?

Thanks for the input. We got the strawberry Touché lube as a tester a while back and it's really chemically tasting.
I'm kind of glad nobody came back with an obvious answer that we've been overlooking for years. Did use olive oil once which worked but isn't great as a mouthful.

Thank AA. Just had a browse through the silicon lubes and have ordered one the reviews say is tasteless. Will give it a try, can always use it elsewhere if it's not right for the job ;)
