A boy just takes his girlfriend back to her home after being out together, and when they reach the front door he leans with one hand on the wall and says to her, "Sweetie, why don't you give me a blowjob?"
"What? You're crazy!" "Don't worry, it will be quick, no problem..."
"No! Someone may see - a relative, a neighbor..." "At this time of the night no one will show up."
"I've already said NO, and NO."
"Honey, it's just a small blowie... I know you like it too."
"NO!!! I've said NO!!!" "My love... don't be like that.."
At this moment the younger sister shows up at the door in nightgown with her hair totally in disorder, rubbing her eyes and says,
"Dad told you to blow, or that I must blow, or he will come down and blow himself, but for Christ's sake to tell your boyfriend to take his hand off the intercom."
