Jay and Sarah came home from the gym, tired and sweaty. She worked out in a loose grey tank top with a hot pink sports bra peeking out from around the collar, hugging her small, but perky a-cup breasts. The yoga pants she wore clearly defined her thin and tight rear and thighs she had, though the tank top obscured this. She often felt self-conscious at the gym, especially when they worked with their new personal trainer.
"Ally worked us pretty hard today," Jay said. He wore his usual shorts and tank, which showed off his biceps and chest. Lately, he hadn't been making much gains as much as just maintaining, but his arms were well-defined.
As they unshouldered their gym bags and dropped them near the door, he caught the playful look in Sarah's eyes.
"Oh? How hard did she get you?"
They walked through the living room to their kitchen, where Jay got out two glasses. He began filling them from the fridge dispenser. "She's attractive," he said carefully. "But if I don't focus during squat lifts, I could fall flat on my ass. With a chub poking out."
"An impressive chub," she said, stepping behind him. "Your thick, girthy chub..." She began to rub his crotch through the gym shorts.
He smirked. "You know that 'chub' is not great for sexy talk, right? It's kind of silly."
"But didn't Ally look good today though?" She continued. "She's got such a sexy body."
"She does spend all day working out. It's part of her job requirements," I said.
"Abs, long legs, big tits," she said. "I was worried you were really into her..." and she paused here. "Daddy."
This had been happening nearly every time they had a workout session with Ally. Sarah couldn't help but fantasize about how inadequate she was compared to their trainer. It usually culminated in a quickie before their shower since it so reliably got her wet.
"You're not wrong," he said, handing her a glass. "Her body makes yours look like a little girl."
"I'm sorry," she said.
"I know," Jay said. "How big would her tits be on your chest?"
She looked down, raising her hands with palms inward as she measured out. She went out far, too far, by Jay's eye, indicating how big their personal trainer's assets would sit on her thin frame. It would be cartoonish.
"About here, Daddy."
"Yeah," he said, sipping his glass with one hand. The other hand slapped her left breast. "I can't even tit fuck this."
Her knees ground together as she swallowed, a touch of pink touching her pale cheeks. "I know. Sorry, Daddy."
He gripped her face, thumb and fingers pressing in on her cheeks, hard enough to make her open her mouth. "And she's sexy. A full-grown woman. You think you're all cutesy with this stupid face."
He gave a light slap on her cheek, enough to demean without much physical pain.
"Tell me what else makes Ally better than you," Jay put a couple of his fingers into her mouth, fish-hooking her and distorting her mouth as she talked so her words were garbled.
"... urk.. Er... asth es etter..."
"Yes, her ass is better, isn't it? Show me your flat booty."
She turned around obediently, bending forward slightly. He slapped it with an open palm. "God, it's so fucking worthless. There's nothing here. Your ass is worthless. Your tits are worthless. Why the fuck should I be with you?"
She bowed her head, "I don't know. I'm..."
"You make my cock hard."
She raised her head, arched her back, and looked up at him with a big pleased smile. "I do, Daddy?"
"You do. Do you know how you do that?"
"How?"
"By being a stupid cunt, who's willing to do stupid things to make me hard."
She bit her lip, whimpering slightly. "Yes, Daddy. Always."
"Do something now. Make me hard. Your tits and ass aren't going to work. Do something dumb."
She was often quite bad at thinking on her feet in these situations, which was understandable. Their dynamic was such that he often took the reins and directed things, so she always stumbled when she had to think of something to do even though they had a long list of things they'd done before. He always enjoyed watching her struggle.
"I... uh..." She turned around and looked at him, uncertainty in her eyes.
"Come on, you stupid cunt, do something."
In a near panic, she slapped herself. She smiled again, but this time it was a forced one that put him in mind of a kid being told to smile for a family photo. It was a smile that was too wide with too much teeth, a parody of the usual representation of contentment.
He loved her beautiful face, but he couldn't help it that seeing such a beautiful thing twisted and warped into something silly or stupid - by his fingers, his cock, or service to debasing herself for him, always made him hard.
However, he gave her no feedback. He didn't say that he was pleased or displeased. He just glared at her silently. Her smile fell, and she swallowed. Then she stuck her fingers into the corners of her mouth, stretching it out.
He almost smiled at her, but instead flatly stated. "Tell me about your education."
She removed her fingers, and cleared her throat.
"Put your fingers back. Actually, try to swallow your fist while telling me your resume."
Her hand was small, but her mouth was also small. She began to try to cram her fingers down her throat with real effort, gagging at first, but recovering enough to say, "I graduated magna cum laude seven years ago from the University of California, Berkeley. (translated into English from Stupid Whore.) I then graduated from medical school there with honors, as part of Alpha Omega Alpha 4 years ago. I'm now chief resident in my department at..."
She was coughing and gagging through all this.
"Look at you, a grown-ass woman. A doctor and a respected member of the medical community, acting like a stupid whore to get a cock hard. But you know the worst part?"
He pulled up her tank top and reached into her pants roughly, cupping her damp quim. "It's how fucking wet it makes you."
Jay took his hand, wet with her cunt juices, and smeared it over her cute little nose and mouth. "You're fucked up in the head. Any normal person would be disgusted by this. Not act like a fucking btich in heat."
He slapped her again, once again, lightly to demean but not physically harm. He looked down further, and noticed that her knees were spread, with one hand stuck into her pants as she jilled herself.
