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 ... "
