A young guy drops off his girlfriend at her home after being out together on a date. When they reach the front door he leans up against the house with one hand and says to her, "How about a blowjob?" "What! Are you crazy!" "Don't worry, it will be quick," he ensures his girlfriend. "No! Someone might see us..." "It's just a blowjob," he insists, "and I know you like it." "No! I said no!" "Baby ... don't be like that." Suddenly, the girl's younger sister shows up at the door in her nightdress, with her hair a mess and rubbing her eyes. She looks at them and smirks, "Dad says either you blow him, I blow him, mum will come and blow him or he'll come downstairs and blow the twat himself ... but for Gods sake tell him to take his hand off the f**king intercom."
