He wrapped his hands around her hips, staring down at the juicy curves of her ass. Oddly, her prominent pussy was missing its neighbor, the long curve of her labia stretching farther back to where her asshole should have been.
Sensing his pause, Naia looked over her shoulder. "Nymph's don't need assholes. Now hurry up and fuck what's in front of- Oh God!" Mike, wasting no pretense, shoved himself inside her awaiting hole. Her body lurched forward as he pounded her from behind, giving no thought to her pleasure at all. Somehow, this didn't seem to matter to Naia. She panted like a dog, her raspy breath echoing off the tiles of the bathroom.
"Holy shit," Mike shouted, desperately shoving his dick inside. His newfound sensitivity was driving him wild, and he clawed at Naia's ass cheeks, his excitement building. The water around them bubbled with energy, tiny water spheres taking flight and hovering in the air.
"Fuck, fuck, fuck, FUCK!" When Mike came, his vision turned black around the edges, the world briefly losing focus, his back arching as he filled Naia with hot sperm. She let out her own shriek, pushing back against him as her back spasmed, ripples traveling down her spine and legs as she shook uncontrollably.
"Oh Mike," Naia moaned, going limp beneath his hands. She sank into the water, and Mike joined her, the two of them easily floating side by side.
"Naia." Mike was officially spent. He ran his fingers through her hair, sighing to himself as her fingers traced circles on his chest. "That was absolutely magical."
"I'm glad you liked it." Naia kissed him on the neck. "Consider it a down payment."
"For what?" He asked.
"For taking care of me. This place." Naia's face was suddenly serious. "If you choose to stay, you will find out that there's a lot more to do than just live out our days fucking. There are some really bad people out there, people willing to do anything to get their hands on this place."
"Because of you?" He asked.
"The man who built this house didn't just do it for me. He was a collector of magical items. These objects have tremendous power, and he hid them well. My job is to guard the house-because of the spring, I can never leave, so I was the best choice to be its guardian. Every time the house is passed to a new caretaker, I either make the pact like I have with you, or the new owner suffers an accident. Also..." Her face went blank for a second. "Damn. It's that thing I want to tell you again. I just can't remember, it's so frustrating. Anyway, I can't leave this room, or the fountain, once it's repaired for that matter." Naia stroked Mike's stomach lovingly. "Please fix my fountain. I miss being outside."
Mike stared at the canned lights in the ceiling. Magical artifacts? This night had taken a strange, impossible turn. "It shouldn't be too hard to figure out where these magic artifacts are kept. The house is big, but it's not that big."
Naia smirked, kissing Mike on the lips. "You keep telling yourself that." Yawning, Naia stretched. "I'm exhausted. You get some of that muck pulled from the fountain, and you and I can stay up all night if you like."
"Consider it done." He stayed with her for a while, but the water grew cold. Bidding her a good night, he watched as she vanished beneath the water's surface, the cool liquid flowing down the bath drain. Drying himself off, he stretched out on the giant bed. Within moments, he was asleep.
