Sophie "offered" to paint her nails

[Originally by lolwritingcom]

"Mackenzie!" Sophie squealed, hopping forward and grabbing one of her hands excitedly. "How did I never notice what beautiful nails you have? You have to let me do them for you!"

"What?" Mackenzie was still processing Anne's little taunt about controlling all the jets. "I don't... ah, okay, I guess..." Apparently Mackenzie did have to let her do them, because Sophie was not giving her any other choice. Sophie held her left hand while she pulled nail polish out of her purse, with a firm grip that let Mackenzie know full well that she wasn't going to be allowed to use it anytime soon. It was a paper-thin excuse to put Mackenzie even further into their clutches- she didn't have beautiful nails at all- but the guys present were not paying Sophie or Anne any attention.

Meanwhile, Anne was still eyeing the hot tub controls like a new toy she was dying to play with. She smiled at Mackenzie. "All these different buttons... and yet I think I know exactly where to start!" She reached for the control panel, and found exactly the jet Mackenzie was afraid of. Slowly but surely, the stimulation of her nether-regions intensified, until Anne was satisfied that Mackenzie was being thoroughly teased. Mackenzie bit her lip and clenched her free hand in a fist, moaning very quietly. The jet was almost more than she could take. She hadn't wanted to turn it up this high until she was just about to finish... which she now probably was!

"Are you shivering, Mackenzie?" Anne asked, in mock concern. "Let me turn up the temperature for you!" Once again the water heated up, and Mackenzie felt like every inch of her skin was being stimulated. She managed to hold back somehow, but with the heat and the jet going as high as they were, she really wouldn't be able to keep from cumming for long!

"Whoops!" Sophie giggled, dropping her nail brush into the hot tub. "I'll get it, Mackenzie, don't worry." She reached into the water and shocked Mackenzie by giving her pussy a small stroke. It was so unexpected, and she was already so close to the edge, that she almost lost it right then and there. "So, are we finally going to learn whether the carpet matches the drapes? Hee hee!" Sophie whispered in her ear, retracting her hand.

Anne continued to tease Mackenzie, gently altering the strength of the jet, up and down, up and down, until Mackenzie was swaying her hips in rhythm with the changes in strength. Things somehow managed to get even worse for Mackenzie when...
