What does "Serve up a facial" mean?

I was just watching Tosh.O and he referenced Marv Albert trying to eat a woman. I have no idea who that is (I am a woman and I'm only 25) so I went to wiki. It says, "She also claimed that he would force her to "serve up a facial" for periods of up to 45 minutes." Now, I do understand what it means for a guy to give a girl a facial... but for 45 minutes? I feel like there is something I am missing. How can a guy for 45 minutes?
