This is totally immoral! I thought these were disgusting when I saw these being put up in some adult sites as a mean to attract visitors. Now that I learned that this is actually practiced in the US I am totally aghast. Its basic common sense issue for me. If intercourse or mutual masturbation was permissible between biological relations then the society would have allowed each and every one of us to do the same. Further if I am not wrong it has also been proven by scientific researches this form of relationship has a unsolicited consequence only. Therefore this should be stopped as soon as possible.
