When my girl is just out of the shower, I like to tease her ass with a licking around and then get the outside nice and lubed up to shove my finger in as I dine on her snatch. She fucking loves it. Especially when I get her nice and turned on by licking her cunt and then when I move my tongue to her puckered ass, she goes through the roof. I must restate however, everything must be clean before I go near the ass.
You can't just lick the ass without liking her pussy, that's not how it works. I go between both, spending more time on her pussy and just liking her ass every now and again to throw her over the edge. Do it too much, and it won't feel as nice for her.
I do but, when the time comes to taste the sweetest of the sweet, or should that be saltiest of the salty? Never mind........you gotsta go all out and get yourself a brown eye double whopper, with a fillet O' fish on the side.
