"But don't worry -- all the other serving cucks are likely to have as small a penis as you have. In fact, we might even have a "cuckold with the smallest dick" contest at the end of the evening. Our well-endowed boyfriends always find that really amusing -- and of course, so do all the wives."
Your wife has attended several of these "cuckolding wives and boyfriends" parties during the past few months, but this is the first one where you are being called on to be one of the cuckold servers. You're quite nervous, because you know your wife will be very displeased with you if you do anything inappropriate, so you are determined to be on your best, and most submissive and obedient, behavior during the party.
