My wife’s sister visited us yesterday in her brand new Porsche. Astonished, my wife asked her “How could you afford this?!”

“You know, a blow job every now and again makes my husband very generous!” she replied.

Surprised, my wife turned to me and winked, “I think I’ll start doing that.”

“Me too!!” I replied, turning to my sister in law. “What’s your husband’s number!?”
