What is the ruling on a wife swallowing her husband's semen and playing with his urine while he is urinating, out of her own desire to do so?

A Muslim must avoid impurities. As for a wife playing with her husband's urine, she must avoid it if it leads to her being soiled by it, because some scholars prohibit being soiled by impurities outside of prayer without necessity. As for semen, the preponderant opinion is that it is pure but repulsive, and it is disliked to swallow it.
