Moody:
Texas,... John Wayne, do people still know him ?
Can't say I liked his politics (or some of his films), but I did once meet him. I was working in an off-license (a liquor store) in Kings Road, Chelsea, and he came in with an entourage. He was huge.
Moody:
Then I realized that the story would easily exceed 5000 words before any spanking happens since I don't believe in spankings without reason.
Your earlier post said 3,000 words - is there no escape from this cursed inflation? But seriously... even 5000 words can be okay if your build-up is titillating enough (mentions of spanking help in this regard).
Another way round it - if your story leads up to just the one spanking - is to open with a brief passage describing part of the spanking itself (as it starts, or perhaps half way through). You don't have to specify who it is, where, when or why - your readers will work that out later. After this captivating start, your readers will, with any luck, want to read on to fill in the details.
Finally, don't be afraid of a long, stand-alone story. There are probably just as many library members who prefer long stories as there are those who avoid them. But if you want to write a serial, and your goal is to maximise readership, then each part needs to have its own spanking, otherwise you're saddled with that dreaded white circle signifying NO ACTUAL SPANKING which is guaranteed to send fair-weather readers running a mile.
