This boy has just taken 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!" she said.

"Look, don't worry," he said. "It will be quick, I promise you."

"Nooooooo! Someone may see us, a neighbor, anybody..."

"At this time of the night no one will show up. Come on, sweetie, I really need it."

"I've already said NO, and NO is final!"

"Honey, it'll just be a really small blowie... I know you like it too."

"NO!!! I've said NO!!!"

Desperately, he says, "My love, don't be like that. I promise you I love you and I really need this blowjob."

At this moment the younger sister shows up at the door in her nightgown and her hair totally in disorder. Rubbing her eyes she says: "Dad says, 'Dammit, give him the blowjob or I'll have to blow him but for God's sake, tell your boyfriend to take his hand off the intercom button so the rest of the family can get some sleep.'"

This one works best in video form imo
