The often overlooked and ignored aspect of a womans body. Located a mere few inches from her most pleasurable of sexual entrances. Small in size and when properly treated, can bring her and her man ultimate pleasure. Its aroma is amazing and its taste, tangy and zesty. The only place a man can get an ass tortilla or be a bung tonguer. Ones penis can find much pleasure and entertainment there when properly approaching your lady for some fine cornhole action or even just to be a Bum Sniffer. Its form fitting shape is snug against the erect penis and can cause extreme and copius orgasms. A Rectum Rooter sweet spot.
