Blowjob

after a date a guy drops his girlfriend home.When they reach her home,he leans against wall and says "honey will you give me a blowjob"
She says "Are you mad, somebody will see us"
"Come on, who is gonna see us at this hour?Please,you know i love you" he says
"i love you too but i won't" she says.
"Oh come on! There's nobody around, they're all sleeping!"
"No way. It's just too risky!"
"I'm begging you..."
suddenly her little sister comes walking down the stairs and in a sleepy voice says "Dad says to give him a blowjob or he says i can do it or mom herself will do it,but for god's sake tell him to stop leaning against the intercom!.
