One night a guy takes his girlfriend home. They are about to kiss each other goodnight, but the guy is 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 blow job?"
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 sister shows up in her pyjamas, hair disheveled, and in a sleepy voice she says: "Dad says to go ahead and give him a blow job. Or I can do it. Or if need be, he'll come down himself and do it. But for god sake tell him to take his hand off the intercom..."
