Bloke pulls a scouse bird, they go back to her place and have great sex.
Afterwards he says, "If you think that was good, let me sleep for a half hour, and we can have even better sex. But while I'm sleeping, hold my testicles in your left hand and my penis in your right hand." Girl looks a bit perplexed, but says, "Okay."
He sleeps for half an hour,awakens, and they have even better sex. Then he says, " That was wonderful, but if you let me sleep for an hour, we can have the best sex yet. But again, hold my testicles in your left hand, and my penis in your right hand."
She is a little puzzled and so asks, "Ok, but tell me, does my holding your testicles in my left hand and your penis in my right stimulate you while you're sleeping?"
He replies, "No, the last time I slept with a Scouser, she stole my wallet!"
