Quenching her thirst forever

John put some protein powder in the cup, and pissed in it.

What... what is he doing... Eve was worried about where this was going.

John pinched off his stream, holding his dick tightly in his hand after adding a bit of piss to the shake. "Since I'm going to be predigesting everything you drink and eat as a reward, that means that your entire diet - except for this flavorless protein powder - will come out of my very helpful penis. It will be the source of everything in your life. You will survive on piss, cum, a multivitamin, and this protein. You can eat it dry, or you can ask me to wet it as I just did to help. Before I go any further, though, I need you to finish off this stream. Holding it like this is getting slightly unpleasant, and you know how I hate things that are slightly unpleasant for me. Get on your knees and start drinking."

Eve hesitated for a moment, then got on her knees in front of John's cock and opened her mouth. She flinched a little as the piss hit her tongue. She still hadn't gotten used to the taste. She guessed he was trying to be helpful by taking on some of the work around the house, digesting some of the food for me and all. But damn - she really wish he would be able to do something about the taste.

John released his grip on his cock and the stream started flowing into her mouth. Eve started gulping as well as she could.

"What are you doing?" John said. "Are you sure that you're willing to spill some of your food on the ground like that?" He asked, seeing that as she swallowed and her mouth closed some of it ran in rivulets down her tits.

He made no effort to aim for her mouth as he drank down the beer and water. "I worked really hard on this for you. Digesting all of this for you and all. But this spilling... it's wasteful. Ungrateful of the work I'm putting in to make your life easier. While you're eating, I expect my cock to be as far down your throat as it can be. Show your appreciation for my effort by not wasting a single drop."

Eve looked up at him and moved her head down to the end of his dick. If she relaxed her throat, she didn't have to swallow at all. Like chugging a beer, she could just let it all slide down. Somehow, she could still taste it as bits and drops bubbled up into her mouth.

John smiled at her. He had been drinking an incredible amount of water and beer all morning to prepare for this, so he wasn't even close to done. He savored the feeling of her tongue on his cock, and noticed that as he grew harder and poked further down her throat the stream slowed down to a trickle. Good, he thought. Make her work for it.

"I'm even eating these fresh sugared strawberries to help my cum and urine taste better for you - as a treat. You were a good dream slut last night, and I didn't even wake once. You'll find that if you focus really hard, you can even taste the fruit yourself."

Eve frowned and thought hard about it. She felt the acrid taste of piss swish around her tongue as she looked up at John. He had a relaxed, orgasmic expression on his face as he took bites and nibbles of the sugared strawberries she had laid out. After focusing really hard, Eve found that she could actually taste a little bit of the strawberry flavor coming out of his cock. She made a very slight pleased sound, even as her face still scrunched up in distaste from the main flavor of the piss.
