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 seclude 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 asks "Are you willing to pleasure me as I pleasured you today?"
You give Clia a puzzled look. "But you have a fish tail."
"The taste may be strange at first, but I think you will learn to enjoy it."
"So mermaids do have vaginas?"
"Of course, silly human. How do you think merpeople breed?"
You felt her scales just below her waist, but there was no apparent opening. Clia brushed your hand away and lay on her back. "Try again."
You noticed an eager look on her face. You slipped down her body to where her groin would be if she was human. You probed with your tongue, finding only scales at first, with a fishy taste you didn't care for. You glanced at Clia who nodded for you to continue. If she didn't seems so hopeful you would think she was just toying with you. More probing with your tongue until...did you find a loose scale? You focus on the area and feel your tongue began to slip between her scales. You probe more eagerly and, like patiently working the tightest treasure chest lid with a crowbar, you slowly open up a slit.
Clia squirms. "That's it. Keep going. Please."
There's a longing in her voice you haven't heard before. You began working the tightest vagina you've ever encountered. As you do, you notice the taste inside is different that the scales of Clia's tail. It's almost intoxicating. You continue to pleasure Clia and start feeling horny yourself. If only you had your penis! Your efforts are drawing soft moans from Clia when you feel a growing warmth and pressure in a familiar location. You feel your own groin but find nothing yet. Your tongue is now thrusting deep into Clia.
Suddenly the mermaid's body tenses and you can taste a new, sweet fluid in your mouth. A cry of pleasure from Clia indicates she's had what you imagine must be her first orgasm. Then you feel something push you from your scales. You sit up, in the mer equivalent to kneeling. There's something sticking out of your groin. You can't believe it, but a gentle grab and stroke confirms. You do have a penis a merman ! Eric lied to you! Or is he a virgin and doesn't know?
Clia props herself up on her elbows. "Are you just going to stare at it or are you going to mate with me?"
You kiss her, more passionately than ever, and she returns the sentiment. You slide into her. It's the tightest yet slickest vagina you've ever been in, and it feels amazing. You begin thrusting and slowly establish a rhythm with your mermaid lover. It doesn't take much to drive her to another orgasm. That causes you to climax, pumping your seed into Clia, which triggers more orgasms for her.
When you're both finally finished, you collapse next to Clia. Maybe being a merman wont be so bad after all?
