Her date had taken her out to a really high class restaurant, so she figured it was only polite to get him a discount. Every restaurant allowed women to give the waiters blowjobs in exchange for a 5% discount off the total bill. The waiter had a nice cock and his cum was delicious, so really it was like she was getting her date a discount and a treat for herself. Her date thanked her for being so thoughtful and promised to pound his cock down her throat when they got back to his place.
