"You see, although I am young....I am what you would call a nympho when to anything related to sex. I am so incredibly turned on right now, and I need someone to help me with this. I know your wife wouldn't mind sharing you with me. Beside you used to babysite me when I was younger....remember that?"
"I suppose your wife wouldn't evenhave to know about your backyard adventure today, your littering in the alley or our little redevous right now"
You firmly object, as there is no way you were having sex with this young girl, however hot. Needless to say she lives right next door, your wife would surely find out"
