Two boys sharing an old mature woman can be a steamy, intimate scene in a movie. The difference between this and porn is that in the latter it can get you arrested (as in obscenity) and in the former it doesn't. In reality though, two consenting adults sharing a relationship doesn't necessarily constitute "porn." So if you're wondering how two boys could share an old married woman (most likely Mom), just log onto the Internet, go to a site that lets you join as a member and see what options are available to you..
