ALS: Ass Licking Slave
While engaged in conversation the other party indicated that they were ALS. By their definition, they enjoyed analilingus without performing any other sexual acts. This can be offered to individuals or groups.
I love the shape of your wife's ass and would love to be her ALS and serve her very well, if you are ok with that.
