You show up to help your mistress with an event, but this time your girlfriend insists on coming with you. You've been helping her with these for awhile, in more ways than one. Not only do you serve guests, you serve her. Sneaking around throughout the party as she secretly and not so secretly makes you tongue her sweet hairy pussy and round ass under a sundress while laughing behind your girlfriends back. It's really cute that she thought she could come along and compete with your beautiful mistress. She has no idea what power her face and body have over you. Once the party winds down she invites you both back to a quiet room to show off some sexy outfits she got as a gift for hosting. You can't help but drop to your knees and serve her right in front of your girlfriend. What a good slave.
