"We should call it a night" said Adrian. "I have to get up early. Some of the fishermen always seem to need things before they head out at the crack of dawn."
Marina nodded. Adrian walked over and scooped her up in his arms.
"How's your tail after being dry for several hours?" he asked. "Do you need to spend the night in the bathtub?"
"I was hoping I could spend the night in your bed."
"I was hoping you'd say that."
Adrian carried Marina down the hallway to the houseboat's only bedroom and laid the mermaid on the bed. Then he quickly undressed, giving Marina a look at his tanned, athletic body. She had admire Adrian from the first day she rented her boat. Marina hadn't expected to end up in bed with him, but she hadn't expected to end up a mermaid either. He climbed into bed and they shared their first kiss.
Many more kisses followed and hands roamed over bodies. Adrian began kissing his way down Marina's neck to the breasts he had been admiring for hours. The medallion was nestled between them. Adrian took a moment to regard the beautiful mermaid engraved on it before returning to the beautiful mermaid it had created. Marina couldn't believe how sensitive her breasts were, which she assumed was a side effect of her transformation. She wrapped a webbed hand around Adrian's penis, stroking it. With her other hand she made sure her vagina hadn't been moved or altered by her transformation, but found the wet slit right where it would be if she still had legs. Not wanting to wait any longer, Marina guided Adrian into her. She clung to him as he thrust, her tail flopping unconsciously. She could feel wave building and then it crashed over her, her tail curling up to brush Adrian's back with the tailfin which triggered his climax.
Man and mermaid collapsed into each others arms.
