Author's Notes: All characters are over 18. The story is concluded.
In spite of the category there is not much non-consent. This is an over-the-top free use and piss fetish story, and there are strong elements of dominance/submission, self-deprecation, and voluntary sexual slavery. There are some exaggerated stereotypical gender roles. If you have a hard time with any of this or with verbal or physical degradation or body fluids, then this story is not recommended.
-------------------
Dan figured he had all he could wish for with his girlfriend Erica. She was beautiful, flawless, popular, commanding a following of other girl hangarounds, and through sheer luck had chosen him as her boyfriend to complete her image.
He wasn't a slouch himself. After an early life as a straight-A student he was developing his social skills as a PT at the local 24/7 fitness. There was a year until his economics degree, and then he was set to work his way into the family business with nation-wide growth potential, but that future still seemed far away. He and Erica were just 24, and their relationship was just 3 years old. Being honest, the only thing really on his mind was squirting his cock into her tight, hot cunt-squeeze as often as she would let him.
Erica actually had some other hopes for their future, of course. Running a boring HVAC firm out of a smaller town didn't quite fit with her idea of a stimulating life. Dan figured she would probably come around, and then her social creativity would take his business to the top. It was just one more of the many qualities he loved her for. He knew he would really have to treasure this girl to keep her, and he made a point out of staying monkishly faithful, even as his new, hard-ass friends from the gym shared stories of anal perversions and one-night stands. As much as selfish pleasure tempted him, it wasn't in the cards for everyone. He would be better off in the long run if he tried to ignore the sexual obsessions his sick mind pestered him with, choosing instead to nurture the loving partnership he had already built.
So, he had to hide how intrigued he was when the news came.
"I sort of promised a girl in our study group to move into the spare room for a few days," Erica explained one day. "I hope it's ok. I mean, she just needs help for a while. She'll be out in no time."
The very small room was actually more of a walk-in closet, since they had put up hangers and used it as storage. But they kept his old bed in there. Technically, it was in fact his closet, since this was all his apartment, and as owner he had no objections to having another girl around.
The day came, and a surprise walked in through the outer door. The girl didn't fit in with Erica's normal entourage at all. This one's name was Tricia. She was their age, but compared to their well-exercised bodies she was distinctly chubby. Her face was short somehow and a little too wide at the same time, and her hair was long, black, and straight, hanging down all over her breasts, which seemed big and saggy even through the clothes. This was obviously one of the more socially inept girls Erica hung around sometimes to make herself look big-hearted. You could tell from their interaction how Erica considered herself superior, and the girl appeared to agree. Then, the shy eyes of their guest studied Dan, and they looked awestruck.
She had multiple layers of clothing, but she didn't appear to have a bra, and the eye-catching, very free dangling of her sizable breasts soon had his cock pushing out his briefs. Her ass was round, looking soft and cushiony, making you want to touch it, grab it, squeeze it hard. He had some trouble accepting the arousal he felt over this shy girl, who wasn't someone he normally would even look at. Maybe there was something about the submission in her eyes, promising opportunities he no longer dared to dream about in his everyday life.

"Oh, fuck yeah baby," his girlfriend panted out that first night, climbing on top of him. "We're gonna fuck so good now!"
He was surprised by how determined she was. She sat on top, squeezing his entire thick and long cock with her smooth, tight body. A perfect, smooth-shaved cunt was grinding itself to orgasm against his rock-hard abs, smearing horny juices all over them. You could hear the wet slaps between their crotches, fucking his cock into her warm depths. She was moaning out loud, and he knew you could hear them through the wall into the closet. She was flaunting her flawless life for someone less privileged, and she was getting off on it. Her orgasm cry was meant to leave no doubts about what happened. The superior people were fucking and loving it.
It was amazing to see the girl he loved so willing, and her excitement was easy to understand right now. There was a whole new dimension to fucking for another person. He imagined the lonely desperation of the girl right on the other side of the paper-thin wall, and then he started grunting loud enough for her to hear, and soon he pumped his sperm into the well-aerobicized cunt that actually fucked him, milking him through loving squeezes.
"Oohhh, yeaahhh baby," he cried out. "Aaahh, I'm coming! It's so good! Aaahhh, I love you baby!"
For a few weeks, this world they shared became ideal. To Dan's delight there was now fucking every night, and his girlfriend seemed excited to make more and more noise, making sure everyone knew their place. In daytime, Tricia came off as enthralled to just be around them. She would always hurry out of the way. She would always hunch her body, showing her lack of confidence very openly.
The first time he touched Tricia, she was standing in the way of the coffee cups. There was still nothing about her cowering body that was supposed to attract him, and there was nothing about her personality that was supposed to appeal to him, but the sight of her loose tits and ass always stiffened his cock, and today he couldn't resist. He reached out from behind, and then he put his palm down on her ass to move her. He knew he was out of line, but he was also certain by now that he would get away with this.
"Yeahh," he grunted in her ear with the plumpness of her ass in his hand. "We need to move you a little. Mmhh, yeahh. You don't mind if I grab your ass, do you?"
His fingers squeezed a little harder, making it clear that he was in fact taking advantage of the timid house guest. Then, he got even more courageous and pressed his now erect organ into her ass-cushion. The soft warmth was insanely comfortable. Her ass seemed made to take cock, and at this moment, he was almost prepared to risk anything just to feel that ass for a few minutes.
Tricia's response came as a bit of a surprise.
"Mmfhhh," she let out through a timid half-gasp, half-moan. "You can do whatever you want to this body. You can! Anything!"
She turned around and looked at the floor in shame, facing him now, bringing her bra-less tits into focus under a stretching top. The nipples were dark and stiff, protruding very clearly through the white fabric. He felt drawn without control to those horny squeeze-bags, which jiggled almost without restraint.
But he couldn't give in to his desire to just grab her fat body and fuck it hard. The thought of what he stood to lose made him force himself to take his cup and go. He was faithful! She would be out of his life soon anyway.
A silent agreement formed in the household that Tricia would start doing more cleaning and dish-washing as her stay grew longer. Apparently, she was perfectly happy to be of service. He often noticed prolonged stares of adoration right at him while she was cleaning up after him specifically.
His girlfriend began to lose her interest in loud fucking for dominance. Instead, signs of irritation towards their guest started to surface.
"Shouldn't you eat less and try to lose some of all that fat?" came a question for Tricia after she had prepared a wonderful dinner. "No sane guy would ever want your body now. I'm just saying it as a friend."
The comment obviously wasn't friendly, and then everything derailed when a helpless Tricia threw a split-second glance over at Dan, and he failed to come up with anything to support his girlfriend.
His girlfriend spent more time out with her other friends, and now she started complaining about taking Tricia along during those nights. Tricia was part of their study group because apparently she always understood the difficult stuff and was always willing to help, but classes were over soon, and her usefulness was running out.
