Wash

Liandra thought the request was strange, but she didn’t mind. What harm could bathing do?
She removed her dress and undergarments and, completely nude, stepped into the pool. The water was warm to the touch and if felt wonderfully refreshing. The pool was not very deep and she was submerged only up to her knees.

Water flowed into the pool from an overhead arch, making a waterfall that sparkled in the dim light. The princess stood underneath it and began bathing while Aquis waltzed around her. After a brief moment, Aquis paused just behind Liandra's shoulder. It's touch was gentle and Liandra found herself enjoying it.

“Please, allow me to help.” Aquis said.
The liquid version of Liandra hugged her from behind and and ran it’s hands across her body. Its touch was gentle and Liandra enjoyed it.
Aquis washed all of Liandra’s body. Her arms, her legs … even her breasts. It was a pleasurable feeling so Liandra merely relaxed and allowed Aquis to do as it pleased.. The princess hadn’t realized it, but her nipples had already become hard with excitement.

Aquis really did intend to wash the princesses entire body. Eventually one of it’s hands flowed down to her pussy and took hold of it. Liandra gasped, reveling in the new sensation. She allowed Aquis to continue and soon she was moaning.

Unbeknownst to Liandra, Aquis slipped a small finger inside her pussy. It had adjusted the shape of it to be extremely thin and, once inside far enough, it expanded again. When Aquis' phallic finger in her pussy touched her walls, she moaned again, thinking it was all a reaction of her own body.
Aquis then moved it’s ‘cock’ in Liandra’s pussy. It shifted it up and down alternately, and throbbed gently. Liandra accepted it’s ministrations and found it difficult to keep her hips from moving. She placed one hand on her underbelly, focusing on the feelings inside her pussy. Another hand made for her breast where she kneaded and squeezed in time with the movement inside her.

Soon the room was filled with the moans and groans of the princess while the water spirit gave her a thorough fucking. When Liandra orgasmed her inner walls contracted and pulsed, causing Aquis' cock to explode. Tiny drops of water were sent in every direction and flowed deeper into the princesses womb. When Liandra had caught her breath and could stand on only mildly shaky legs, Aquis released her.

“Thank you for this payment, my dear. As my gift to you, you shall no longer have to worry about your marriage to the prince.”
"But.." Aquis placed a finger to the girl's lips, effectively hushing her.
“No buts, dear princess. Everything has been taken care of and will fall into place accordingly.” Aquis explained.
"That's wonderful! Thank you so much Aquis!"

Following Aquis' directions, the princess made her way out of the ruins and went back home to the castle.
