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!”

Him: “Oh come on! Who's gonna see us at this hour?”

Her: “No, please. Can you imagine if we get caught?

Him: ”Oh come on! There's nobody around, they're all sleeping!“

Her: ”No way. It's just too risky!“

Him (horny as hell): ”Oh please, please, I love you so much?!?“

Her: ”No, no, and no. I love you too, but I just can't!“

Him: ”Oh yes you can. Please?“

Her: ”No, no. I just can't“

Him: ”I beg you…“

Out of the blue, the light on the stairs goes on, and the girl's
little sister shows up in her pajamas, hair disheveled, and in
a sleepy voice she says, ”Dad says to go ahead and give him a
blowjob. Otherwise I can do it. Or if need be, dad says he can
come down himself and do it. But for God's sake tell him to take
his hand off the intercom!"
