I was very nervous dialing the number. It’s one thing to look at pictures and fantasize about sucking a dick, but quite another to take a first st...p toward doing it. I dialed 4719 and listened to the phone ring four times before someone picked it up. When I heard him say “hello”, I came to my senses and quickly hung up the phone before he could say anything else.
