I suspect that for the "right" man, many women will do this. How is he the right man? Maybe he is a ultra handsome, desireable man who has his pick of women and you do it to be "special" for his sex life. Maybe he is rich and you must do what other women do to land him and his cash. Maybe it is true love and a true desire to sate his desires. Or maybe he is a man who fully expects the women he has sex with to be pure, unapologetic, total sluts and he demands they do what he considers being a slut. Would I rim an ass like she does? Maybe for the "right" man I would.
OMG! That is awesome. I'd love to have you sucking my cock from behind. The way you work over the asshole and the balls drives me crazy. I came just thinking about you kissing me after you finished him off!
