The mix of Clia's pheromones and your own still-unsatisfied horniness makes for a heady brew indeed, but not so much that you're ready to be a dad. You want kids someday, and you want to give them to nobody but Clia, but this isn't the time. Not until you've settled into your life here and made sure that you make a living, provide for a family.
"Let's wait until we're ready," you say. "There's always next time."
Clia smiles and nods. You can see that she's a little disappointed, but also relieved. "I understand," she says, and she kisses you again. Then she does something you don't expect: she reaches down to the little nest and runs her hand through the pile of eggs. Her fingers are now coated with a little bit of that orange fluid, and she brings them up to your face and tells you to smell. It's another sudden jolt of aphrodisiac hormones, and between that and your serious case of merman blue balls, you can tell that if you were still human, you'd have the mother of all boners right now.
Clia uses her tailfin to cover the eggs over with sand. You get the sense that she's saying goodbye to a child who will never be: it's a profound little moment, but a moment only. Then her attention is all over you, and she begins to pleasure you, lavishing your body with much the same attention that you were only minutes ago giving to her. She uses many of the same techniques, which isn't all that surprising given how similar merman and mermaid anatomies really are when you get right down to it: kissing every little place on your human half that is in any small way an erogenous zone, paying particular attention to the gill-slits in your neck and the now painfully-hard and very sensitive nipples that adorn your manly pecks.
It feels different now, to the way that Clia would tease and kiss you in your bed together in her home—not because of the pheromones or the mating season, not really, but just because of the way the mermaid is behaving. It's different because she knows now that it isn't just a tease and bit of love-play foredoomed to frustration without release. She's making love to you with absolute abandon, driving you closer and closer to a climax that she knows you can actually reach now that the time is right. She has every reason now to keep at it and not give up or let you give up—
And God DAMN, are you ever tempted to give up now, because the mermaid's gifted tongue on your chest has very quickly got you gasping for seawater, just as you were doing to Clia earlier. It's so damn good, so amazing, and you're at that plateau, and you also know that just this alone won't get you there.
You can barely think at all, Clia's lips and tongue have you in a daze of overwhelming and frustrating pleasure. And then she begins to kiss her way down your chest, down your respectably toned abs, playfully pausing at your navel to give it a little lick (if merfolk are egg-layers, how and why do they even have navels? who cares?), and then down to where skin transitions to scales. She has one hand firmly on your ass, pinning your writhing body to hers, while her other hand continues to casually flick at your nipples. But her tongue: she brings that down to your own fishy opening, and she starts to lick and tease at it, and dip the tip of her tongue the very tiny distance that it will go inside. And it's fucking INCREDIBLE. It's not like a blowjob and it's not like vaginal sex, but in the mental and physical state you're in now, if this is the best you can hope for, it's definitely more than enough.
After upwards of fifteen minutes on the edge of a shattering orgasm—it very suddenly, and calmly, ends. You realize as you come back to yourself and your ears quit ringing that you had been gasping and crying out in pleasure too. A milky white cloud has formed around your genital-vent and Clia's lovely face, and she is doing what she can to either waft the cloud away from her nest with her hands, or to take the wisps and globs of whiteness into her mouth and swallow them down. As for you, you feel satisfied. You've had release. The orgasm wasn't actually all that intense (in fact, the release of your ejaculate into the water reminded you of nothing quite so much as a good pee after being obliged to hold it for a really long time), but it was definitely a climax of a sort. It was brief and low-key and not localized to any particular part of your body, and it was definitely different from what you were used to as a human.
But your body is satisfied, and you're more content than disappointed.
"Well?" asks Clia, grinning from ear to ear. "Was it worth the wait?"
You don't really know what to say. You just grin back.
Then Clia says, "And that was just the beginning. They say it gets even better for a couple, once all of a mermaid's eggs are out. We've got the rest of the cycle to frolic together, and no more worries about fry!" As she talks, Clia gently kisses and laps around your midsection, cleaning the mer-jizz off your scales—and your heart swells. It gets better? You certainly hope so—this was a release from the tension, but in all honestly it was barely even adequate compared to a human orgasm.
No, what made it worth it was the fact that it was with Clia, and that you were now certain of one thing. You were as much head-over-fins in love with this mermaid as she was in love with you.
Maybe being a merman wouldn't be so bad after all. At least, it wouldn't be if the rest of the week was going to be as good as Clia was hinting it might.
