You need to try the rape choke on the wife next time. It's part of any sub / Dom games, quite exciting, brings a whole new dimension to the bedroom. Be careful though so you don't choke her lifeless, that happened to the singer in INXS.
So here you go. When she is about to come, place your fingers on each side of the throat. Do not push your hand towards and into her throat. That'll just make her cough. Squeeze your fingers together firmly and hold. Watch her come like the chop chop train. Et voila, you are the papi in bed.
I don't know if it works on ostriches or swans, but I don't have a huge urge to find out. I would try to finger a gorilla once though to see if I could make her come.
