Lots of potential fun to be had.
Making pee ice cubes out of your wife's piss and putting them in your drinks.
Letting her pee all over you after drinking a lot of water so it is colorless and odorless,
and then not washing it off. Go about your day.
Having her pee into a jar of her used panties. You have to wash the panties in the jar, suck the crotch dry, squeeze the panties so all the absorbed pee goes back in the jar, and then drink everything in the jar.
