Just do what I did. Tell her to get in the
doggystyle position so you can eat her pussy that way. While you're sucking the life out of her body, just spread those cheeks and lick that ass. Guaranteed she won't stop you. I do a long lick starting from the pussy to the ass, then go backwards. Suck on the ass for a while and make her ass go crazy. Ass licking, FTW!!!
