Ok, here's a joke I heard recently. Not bad but hardly special. And a little disgusting.
A guy walks his girlfriend home late one night. They've had a great evening out but nothing sexual has happened. After getting to her house, the guy feels fairly horny. So he leans against the wall and says,
"Hey, darling. Why don't you give me a blowjob"
She replies, "No. We can't. Someone might see us."
"Come on. Who's gonna see us at this time of night. Please."
"No, no I can't. What would everyone think of me."
"Oh please, please, please."
"No, not tonight."
Getting desperate, "I beg of you. Please give me a blowjob."
Then the upstairs light comes on, and the girl's younger sister appears at the top of the stairs.
The younger sister says, "Dad says it's ok to give him a blowjob. If you don't want to, I can do it. And if it's absolutely necessary he can do it. But whatever happens....
TELL HIM TO TAKE HIS BLOODY HAND OFF THE INTERCOM!!!!!"
