"Mini Skirt" joke

Joe is sitting on a train across from a busty blonde wearing a very tiny mini skirt.
Despite his efforts he can't stop looking at her thighs. To his delight he discovers that she is wearing no underwear.
The blonde suddenly notices that he is looking and asks, "Are you looking at my p*ssy?"
"Yes, I am so sorry! I just couldn't help myself. I will stop right away."
After a while he starts to look again.
"Are you looking again?" the blonde asks.
"I am so sorry, I just can't stop!" he says.
"Oh, it's okay. It's quite talented, watch!" the blonde says.
As the man is watching it blows a kiss at him!
"What else can it do?" he asks.
"It can also wink at you," she says. The man stares in disbelief as it winks at him.
"Come and sit next to me." As the man sits down she asks him if he would like to stick two fingers in it?
Then the man says, "Why, can it whistle too?"
