I absolutely love tonguing my gals asshole and tickling her in that area. She has such an inviting area, small patch of hair, very pink asshole, tight butthole, and very tasty as she keeps it clean. My question is. I normally use my cum from fucking her pussy and then cumming on her asshole, or I use spit...this seems to lube her up but she does moan and scream when I am fully inside her ass and buttfucking her. I just wonder if I should use a grease or lube? I love using my own cum but I also don't wanna hurt my favorite orrifice...
