A young man and a girl were on a date. He was getting hot and finally said, "Let's fuck". She said, "Oh no. I never do that". So he said, "Well, how about a blow job". She said, "Oh no. I don't do that either". Finally he said," How about giving me a hand job." She said she didn't know how to do that. So he said, " You remember when you were a kid, you used to shake a soda bottle until the pressure built up and it squirted? Just do it like that." So she took hold of his cock and began. Soon suddenly began to scream. She said, "What's the matter?" He screamed, "TAKE YOUR THUMB OFF THE END OF IT."
