Just give her a lick and when she finishes off use her cum and a bit of spit as lube, it works the best and those juices are there for that purpose, to make the penetration smoother. 

Sounds nice, but in reality, no girl would accept something like that. That juices would be full of your saliva and could transmit STDs through the tiny ruptures in her rectum which are more than likely to happen during the greek.

Thanks, hope it will work out. Can women squirt from anal sex? 

I saw that only on pornhub.

Of course mate. Tissue between anal canal and vagina is very thin and it's easy to hit her in the G spot through anal canal, go and see on pornhub or other websites anal squirt orgasms, it's even more intense than from vaginal penetration.

Do her a clit massage while trying initial penetration down there, it will loosen her sphincter up and make the penetration less painful and easier.

Just be gentle, try to relax her as much as possible, use lube and don't go full length at the beginning, first the head then continue with gradually extending the penetration.

Im open for more recommendations as well, not only about lubes, thanks for your advice mate...

Only silicone based lubes, they'll not dry out after a while. Is that the only thing you're unsure about or you want more advice since it's your first time? 

Im about to experience greek for the first time but don't know what lubes I should  use, any recommendations?
