One night a guy takes his girlfriend home. As they are about to kiss each other goodnight, the guy starts feeling a little horny. With an air of confidence, he leans with his hand against the wall and, smiling, he says to her, "Darling, would you give me a blowjob?"

Horrified, she replies, "Are you mad? My parents will see us!"

"Oh come on! Who's gonna see us at this hour?"

"No, please. Can you imagine if we get caught?"

Now, horny as hell he says, "Oh please, please, I love you so much!"

"No, no, and no! I love you too, but I just can't!"

"Oh yes you can. Please?"

Out of the blue, the light on the stairs goes on, and the girl's little sister shows up in her pajamas, and in a sleepy voice she says:

"Daddy says to go ahead and give him a blowjob. Otherwise I can do it. Or if need be, mom says she can come down herself and do it. But for God's sake, tell the butthead to take his friggin' hand off the intercom! We're trying to sleep!"
