I didn't know this practice had a name either...but I do find it fascinating...but then I can say that about most any kind of sex. I personally like to dump a big load on my girls face and then make her leave it there for the balance of the evening. I find it very sexy seeing her tied down with cum dripping down her cheeks. As for bringing in a crowd to contribute? I don't know that I would want my girl to be the recipient...but I certainly wouldn't mind watching!
