Take Xiarel again right here

Hearing her sweet voice, and her gentle touch has made you hard again. You don't want to risk further damage to your testicles, so you roll on top of her, and cup her cheek, asking, "Would you mind if I fucked you again?"

She gives you a gentle smile. "Of course! This is a very unique experience for me. I never knew fornication with you land dwellers would be so pleasurable."

Just as you slide your cock inside her again, you pause, as her words register. "Land dweller?" you ask.

Xiarel nods. "Yes, I'm a maiden of the sea, a mermaid."

You gasp in shock, only now noticing that on the sides of her neck are gills, and that she has no nose. Her fingers and toes are also webbed, and on her shoulders you spot some lime green scales.

"Can you breathe on land?" you ask, your hips starting to move on their own.

With a moan she nods. "Y-yes, but it takes practice."

Well, this was certainly an unexpected development, you think to yourself. You've only heard myths and legends about the sea dwelling elves, but now you are fucking one.
