Witches brew is a family term for coffee. The stronger the coffee, the more it deserved the name of "witches brew". I think it got this name from the strong flavor of the coffee and the busy behaviour of people who drink too much coffee.
Mother laughed as she poured the hot liquid she called "witches brew" from the coffee pot into the porcelain mug. "Here", she said, offering me a cup of her famous witches brew.
A liquidy, bubbly fart--think of the simmering, foul concotion typically found in a witch's pot--that unfortunately results in a little surprise in one's underwear, and comes with the sickening realization that something slipped out that shouldn't have. Most uncomfortable and difficult to explain when in a public place, far from a toilet. Impossible to deny.
I was getting blown by this hot chicklast night when I got a sudden episode of witches brew and she threw up on my balls.
When one goes for a long period of time without ejaculating. The cum is brewing and festering waiting to be unleashed. Its as if a group of witches are brewing something in the bottom of a guys balls.
