Smarter Than It Looks

Astri can't deny her hot merman to wash her the way he wants. There's no other place he likes to be with her than water, he helps her wash her scalp and hair, her arms, back, then chest and breasts, building up her desire for him.

He washes her legs and then kisses her feet.

"You're not making things easier, Koa.. We're outside and we can't be loud.." She says in a low voice.

He brings her to a rock inside the water and then sits her there. The water is on her chest, he mischievously smiles at her and goes underwater. She holds her gasp with her hands when she feels his tongue between her legs. He creates a vibration with his merman powers and uses his tongue to make her come undone easily. 

"Remind me to build a bigger bathtub.." She says, heavy breathing, after he puts his head outside the water again.
