His phone buzzed on the desk, and he checked his texts. It was his wife, on the profile they used for dirty talk. "I'm horny, Daddy. When are you going to be home?" That's the kind of thing a man likes to see. His cock started to stir at the thought of her at home, desperate and squirming with need. He sighed and looked at the last few students struggling through the final lab exam.
"It's going to be a while. Sorry."
"What do you want me to do while I wait for you?"
She could have gotten herself off. It wasn't forbidden. He loved the idea of a sex-crazed wife at home, especially knowing that the orgasms she gave herself were never as good as the ones he commanded. If anything, they made her needier. But today she had asked.
"Put in your ben-wa balls and a plug. Edge three times."
The last two students seemed to take forever. With the last exam in and the tests dropped off for his grad student to grade, he zipped home. She was exactly where he thought she would be. In the bedroom, she lay sprawled across a nest of pillows. Her pale skin was flushed pink. Her hands were slowly twisting and tugging her nipples until tiny signs of pain flashed in her eyes.
"I did two of the edges, Daddy. I wanted to save the last one for you." She smiled sweetly at him and spread her thighs. He settled into the bed to watch. The slim pink handle of a plug peeked out below one very wet pussy, stuffed with the magic balls that vibrated with every movement. He gave two sharp slaps to the backs of her thighs, eliciting a jump and a yelp that faded into a little moan.
"Pathetic. Look at that messy little pussy. What kind of a filthy little slut has a pussy like this?" His voice was stern, maybe a little menacing, but his eyes were playful. He let his fingers glide through her folds. She shuddered in pleasure. He slapped her lightly, right over the clit. "Answer me."
"Your slut!"
"Good girl. Now show me how you edge." He liked that she blushed a little, even after years together. But she didn't hesitate to grab her vibrator and start grinding against it. In no time, she was whimpering and writhing, trying to get as close to the edge of orgasm as possible without tipping over. With a gasp she flung the toy away from her, breathing hard.
"How do you feel now?" he asked.
"Needy. All the sensations are too much and not enough, and all I want to do is come," she replied. It sounded like she was close to tears. Good. She was a pretty crier. There was something cathartic and primal in pushing her to that point. He studied her in silence. She rushed to fill it, blurting out, "I need your cock in me. I need to be used and fucked. Please, Daddy. I need it."
She looked miserable. He slid his fingers over her slick pussy, and she jerked back. Overly sensitized was fun. "Hold. Still." He hooked one finger through the silicone loop that tethered the ben-wa balls together and slowly tugged the first, then the second free. Her pussy fought him all the way, clamping down on the balls mercilessly. Her body was way past the point of her being able to consciously control it. He couldn't help thinking about how amazing it would feel when those strong inner muscles grabbed onto his cock like her life depended on it.
