Post an ad saying that you are a slut and want to suck cock. You can advertise for a guy or a shemale. It's up to you, just as long as they have a real cock.
Tell them you are a virgin cock sucker and have a fantasy about sucking a cock and having them cum on your face.
Before you post that ad, remember that Craigslist lets you add a picture for free. If you're a real slut you'll include one of your sexy pictures from earlier. Send the one of you without your face.
No one will know. It'll just be our little secret. I promise.
