This question's mainly for the girls. Your friend asked to borrow your new pants, and you allow her to wear them to a party that night. You're both at the party, your friend's wearing your new pants, when she lets it slip (after a few drinks) that she isn't wearing any underwear. How do you feel about your friend's bare crotch rubbing against your new pants?
At the party, she's drunk and she ends up making out with somebody. She comes back later, overstimulated, and blushes when she tells you that she's never been so damp before. How you feeling about those new pants now?
She passes out and you're about to take her to your car when you notice that there's a big urine stain on her/your pants. How you liking them pants now?
