Answers: weird fetish question coffee
Sure, there's fetishes for anything that people do. There are quite a lot of people into feeding people or watching others eat or drink. Sometimes it can become an obsession. There are those that like to watch or cause their partners to gain weight, and some actually spoon feed their partner to this end. Others merely encourage or otherwise convince their partner to eat more.
If you wanted to simply watch girls drinking coffee, that's simple voyeurism, you can go to a coffee shoppe for that. If it arouses you, you might have some discomfort doing that publicly. I imagine there are webcams that focus on the patrons of coffee shoppes, you might try looking for that.
