Sounds like a good deal... for the women.

"So, I'm not saying I'm agreeing, but what do I get out of this?" My hand naturally came around her, and she turned so her back was to me. I enjoyed the feel of her soft breast against my palm as my fingers clenched on her, bringing a soft gasp to Carla's lips.

"Oh, so you're not just going to say yes when I ask. Ok, let's see..." Her hand slipped along my thigh to squeeze gently, the back of her hand grazing my flaccid penis, but definitely making it feel good. Shit, wasn't going to be staying soft long at this rate. "Hmm, I suppose you could get one day too."

"So, One day a week where I just get to tell you all what to do, compared to four where you all get to tell me what to do? That's a rigged game, because you and your sister already double your time." I pointed out, resulting in a quick pinch from Carla.

"Oh, so you're thinking a couple moves ahead now. Let's see if I can get the other brain working instead," Carla snickered, her fingers pulling on my thigh, this time I was sure making deliberate contact with my dick and the back of her hand. I had to keep my head straight here, even though the urge to just nod as she continued the maddening pace was indescribable.

"Uh, uh, no cheating now," I gripped her wrist with my free hand tightly and pulled it away from myself. "You know how much that likes to do the thinking."

"Yeah, I'm thinking how much it likes knowing that it was inside four women. If it wants that to continue, maybe it should take over a bit..." Carla teased, pulling her wrist against my hand playfully. "Oooh, are you going to do awful things to me..."

"Carla, you're way too good at this," I nipped my teeth at her ear, and her shudder and soft exhale gave me all the encouragement I needed to begin kissing down the back of her neck as my thumb rolled over her nipple. I still held one of her hands tightly in mine, and the feel of her skin under my lips as I found the juncture of her neck and shoulder was intoxicating. Impishly, I decided that I might as well leave a mark so that I could easily tell the twins apart, and sucked the flesh of her neck into my mouth hard, biting down just enough to bring a whimper to her lips. She groaned back at me, her hand pulling against mine as her free hand scrabbled at the stone of the tub. A second more and she relaxed into it, her sounds of resistance changing to a mewling purr of contentment.

"Shit... so are you..." Carla breathed out as I released my lips hold on her neck. "Okay, so... There's only Seven Days in a week, Brent. You can't expect four."

"Hmmm, Three to your collective four does sound fair," I grinned a bunch of fantasies running through my head involving bedroom activities. "Course that does put an onus on me..."

"Actually Brent, I was thinking if one of the girls has a work day..." Carla began, rolling her head as I began to suckle at her shoulder again. "Fuuuuuck, that feels good. Ok, fuck... I can't think right now."

"That's the Idea," I spoke, nibbling and sucking at the exposed flesh of her neck as my hand slid down her belly. I still hadn't released her hand, and from time to time she would playfully fight against me, as if testing if I was still paying attention to her the way she wanted.

"You better drink some more water..." Carla cautioned me, as my fingers combed through her lower hair.
