I personally think there's potential to make a more refined scene: like a restaurant that provides personalized and discreet meals where the waitress is preparing/serving the meal to a customer while being mounted from behind (can be in a gloryhole setup so that it's just the waitress and customer in a single space)...
There's just one small issue: when I'm hungry, I'm usually really not in the mood for anything sex related, so there's that!
an Skateata :Do an OCR of the sentences if you're really interested in the plot... But as usual, too much talk can be a turn off, especially if they start talking something you don't really find exciting...
