Handbook of Erotic Fantasy: Fish Foot Fetish (Patreon)

"Really?" she asked, coquettish laugh bubbling up towards the surface. "Are you certain?" 

"Yeah, dude," said the triton. "It looks soft. It looks comfy. Plus I'm pretty sure it's classical."

"What?" she teased. "Were you an art history major?" 

"No way. That class was just a prereq for my school's piracy program." 

She stared at her two-legged lover, uncertain whether it was a fish pun or a the simple truth. He seemed to be serious about the three-way though, not that she was complaining. As any full-time resident of Handbook-World's oceans might attest, pockets of strangely intelligent sea life had been cropping up lately. Pods of chatty dolphins, gossipmongering reefclaws, and even the occasional pontificating sea turtle had all appeared in the setting's depths. While not precisely common, such things as talking bivalves were not unheard of. And as a mermaid, the union of humanoid and fish was not so strange. 

"So," she said to the mollusc, "Think you'll be into it?" 

"Oh yes," said the voice of the clam. "You have no idea how long I've been waiting to have someone like you inside of me." 

For the mermaid, it was an adventurous departure. She had never spoken to a giant clam before, much less propositioned one. But for Swash, being an amphibious triton, and therefore not being a a full-time resident of Handbook World's oceans, and therefore not privy to their secrets, the voice seemed to come from an different clam entirely. 

"Whoa!" he cried in wonder. "A talking clam!" 

"Shall we give this lady of ours the time of her life?" said the clam. 

"Open wide, l'il buddy!" said Swash. 

"Ahhhh!" said the clam. 

"Ahhhh!" said the Mermaid. 

And many a pearl necklace was made that day.
