Man narrates how his wife caught him sucking their house help breast.

As seen on mature minds:

My wife went to the market to buy one or
two
things and left my 4 months old baby to the
19 years old house help.
The little baby
started crying, the house girl has done
everything to make her stop crying , but the
boy kept crying, so the girl now brought out
her
breast to breastfeed the baby, and
immediately
the breast entered his mouth he stopped
crying.
 As the small boy was sucking the
breast, I entered and saw it, I was so angry
and afraid that he could contact disease
from there. I shouted on the girl, but she
told me that nothing was coming out of the
breast but I didn't believe her, she asked me
to test it and I decided to suck the breast
too to confirm.
 As I was sucking her breast,
my wife came in. Upon all my explanations
she refused to understand and it's now a
big problem. What do I do to convince her it
was an innocent sucking?
