I guess is the idea, but not of dirtyness for me, more knowing about the feeling of tasting your own juice and mine at the same time
For me, it's the combination of the two. I get a mental high from the nastiness and dirtiness of my wife sucking my cock after I fucked her ass and/or pussy. That and the physical stimulation from sliding my cock into her throat and her tongue licking my balls get me to cum every time. :2thumbsup:
The feeling of lips on my cock, is indescribably sexy..specially if she finishes you off and cleans up!..I dont know about other guys, but the first eruption from ME!...is just the beginning..having a willing partner, keep going until I am soft, is magical..
