You can get your wife involved here by continuing to fuck your neighbors, knocking them up and making your wife jealous that they are having your babies and she isn't. Then maybe if she is open-minded (if she is not she can go find someplace else to live because you will have started a couple of families), she can get involved, too.
(see prior comment) OR you could just ask her - simple way to avoid the court and possibly increase the pleasure without the eventual pain. Nah makes too much sense eh
If you are thinking about it, then why involve your wife? Maybe Anna and Trude might accomodate taking your sperm to mix with their "eggs"?
