That night you were laying on your seabed silently lamenting the limitations of your merman form when Clia joined you. The two of you cuddled and kissed. She was a beautiful, sexy mermaid but the sexless life was just not for you. Should you try to escape tomorrow? Maybe Clia wouldn't mind going to a secluded beach with you on a regular basis where you could transform back to human so she could pleasure you?
Before you can make any suggestions to Clia, she says, "I know what you're thinking, and I'm sorry, but it won't work anymore." At your questioning glance, she points at your neck. You reach up and feel at your gills, and you also realize: damn, no necklace. Clia didn't give you one after using the starfish this time. Even if you could get away, with or without Clia, you don't know how to become human again. You sigh, forlorn.
Clia kisses you for a long while, trying to cheer you up, or maybe to soften the blow when she explains, "The necklace only works once. Even if I got you another one, and they aren't easy to come by, it couldn't change you back. You're a merman forever now."
You nod. "I understand. It's just—"
"You're sad that I can't suck on your mating-nub anymore."
The way the mermaid said that, so innocent and serious, suddenly makes you chuckle out loud. "Yeah. I'm sad because of that."
"It felt really good?"
You nod again. Clia has a thoughtful look on her face. You wonder what she's thinking, but you're afraid to let yourself hope. Still, you can't keep the eagerness out of your voice as you ask, "How do mermaids mate?"
Clia smirks, sad and knowing. "We lay eggs, just like most fish. It feels good, but probably not as good as what you're used to."
"Can . . . can we try?"
She shakes her head. "I'd like to mate with you, my love, but it's not our time."
You sigh again and drift back down onto your shared seaweed bed. Of course there would be something like that. "So when's mating season? Spring?"
At that, Clia actually giggles. "No, silly human. It comes around every month. For a few days before and after the full moon."
You raise an eyebrow. Several days out of each month? That wasn't SO terrible, provided the actual mating was worth it. After all, jizzing on a pile of fish eggs didn't -sound- very pleasurable. But then you guess that there's no way to know until you try. At any rate, it wasn't like you had many other options. "So, uh, how long do we have to wait?"
"Maybe a week," says Clia, who now lets herself fall down onto you. Her chest presses against yours, and the belly of her fishtail rubs against yours in a way that feels alluring but disappointingly non-sexual. She starts kissing you again, more passionately this time; it's obvious that the thought of mating with you has her excited now.
What a pity, you think, that there's nowhere to go with it. Tentatively, you ask, "Is . . . is there anything we can try in the meanwhile? Don't merfolk have any way to pleasure each other when it isn't mating time?"
Clia answers
