I get it! You're eager for your story to be the hottest, most arousing piece of fiction ever conceived by the mind of Man. (I'm not being sarcastic: been there, done that.) So on page one, your 6'5, 220 lbs (all muscle) protagonist has a 10" cock and can cum like a firehose 6 times an hour. He runs into a supermodel—no, two supermodels! They have flawless hourglass figures, huge HH-cup tits, and the tightest pussies on the planet. They're dressed like sluts on the prowl and they're dripping wet. The instant the 3 of them see each other they all fall in lust, and 2 sentences later they're in a hotel room having the literal best sex ever. They enthusiastically engage in every sex act known to man, invent several that aren't, and repeatedly faint with the intensity of their orgasms. Your superlatives have superlatives. Excellent! ...But now what? How do you raise the stakes from here? Where do you go next when your story starts by standing on the peak of Everest? Leave some room for escalation! Of course your sex story should (probably) be hot from the get-go. Your thriller should be thrilling, your horror movie should be scary. But leave some headroom! When your action hero protagonist finally goes up against the Big Bad, it needs to be a more intense fight than the ones against the legion of mooks he waded through to get to this point. When your on-again, off-again couple finally get their happily-ever-after scene at the end of act 3, it needs to be happier than the first 7 times they got together. After your step-son diddles his step-mother for the first time, don't immediately transition into fucking 24/7, and make sure at least one of them is full of doubt and self-recriminations afterwards, or you'll have no incest taboo left to play with for the rest of the story.
