An old guy says to a prostitute..

"I would be able to make you cry after sex."
The prostitute replys "And how about you come in and prove it?"
So the old fella complies and goes inside and nails the absolute hell out of her.
The prostitute has no tears in her eyes and says to the old man "That was surprisingly good but I'm not crying yet."
The old guy takes his pants back off and says to her "Give me a minute darl while I recharge but why I do that hold one of your nipples and the knob of my cock"
The prostitute is confused but agrees and after a minute he fucks her senseless and surely enough a single tear roles down her face.
With a surprise gasp she says to him "Woah you actually did it but I have to ask why did you get me to hold my nipple and your cock at the same time?"
To that the old guy says "The last whore stole my wallet" as he is leaving the room.
