Placed in Chastity

Isabelle pranced around the kitchen as she prepared Nathan's breakfast. She was wearing nothing but a blue babydoll nightie that was just short enough to reveal her chastity belt when she moved. It had finally been two weeks since she was first locked up and barred from her orgasm. Six days was her previous record, not that she ever tried denial before.

To mark the occasion, she wanted to surprise Nathan with breakfast in bed.

'At least, that's what I'll tell him,' she thought. 'He should be eager to see me naked, grab me, or order me to service him. I know my boy gets turned on by chastity; he said so himself. I assumed he came out of his shell last week. But he's been avoiding me ever since. Not that I want him lusting after me, of course. I'm just horny from all the denial, and I'm projecting. It'll go away after tonight.'

She placed his meal on a tray and brought it up to his room. Nathan was asleep in bed. There was a soft orange glow from the sun streaming in from the window. Isabelle pulled his blankets back and noticed his morning wood pushing against his boxers. She kissed his forehead and gently rubbed his bare chest. His eyes fluttered open, and he looked at her, confused.

"Good morning, sweetheart," Isabelle said. "Sorry for waking you up so early. I wanted to do something nice for you, but I have to leave soon. Work called me in." She looked at his boxers, provoking a slight twitch as she did. "Though we do have enough time to give you some special attention."

Nathan noticed the nightie she was wearing, his eyes drawn to her bare thighs and ass. "This?" Isabelle said innocently. "It's been in my closet for a while. What do you think? Should I wear it more often?" As she spoke, her fingers began playing with the elastic band of his boxers.

"Yeah, I don't mind," he blushed. He glanced over to observe what his scantily clad mom's hand was up to. "Thanks for trying to look out for me, Mom. But I'm not sure I should ask you to do this. I don't want to treat you like an object for my relief."

Isabelle audibly tsked. She pulled down his boxers to expose his hard-on, saying, "And I'm just using you to keep myself under control, is that it? That's not how I see you, so please treat me with the same respect. I want to be in chastity, and I want to follow my keyholder's orders. Please tell me what you want."

After a deep breath, Nathan took a resolute tone, "Mom, I want you to jerk me off."

Isabelle finished taking his boxers off and began gently stroking his cock. The warm sunlight on her body made her satin nightie glow. Her chastity belt, barely visible, glinted in the light. She spread her legs to let him see it more clearly. Their horny breathing and the sound of skin on skin filled the room.

She reached over his head to grab some tissues on a nightstand, placing her tits directly in front of Nathan's eyes. Her perfume filled his nose as she practically laid on him to whisper, "I'll make you cum just like you want. So please do whatever feels right."

He grabbed her thigh with one hand, reaching up her nightie with the other to fondle her breasts. Isabelle responded by tugging harder and faster. She was amazed at how aggressive he could get. In the middle of all this, they happened to make eye contact. They studied the tiny expressions on each other's faces, getting lost in the secrets they told.

Straddling his leg, she dry-humped him as he thrust into her hands. She felt nothing but the dull pressure of a chastity belt pushing against her, but the look in his eyes told her not to stop. Nathan's cock tensed, and Isabelle barely reacted. He shot a load of cum, mostly on his own stomach. She cleaned him up with the tissues, continuing to glance at his face. Both of them were a little disappointed at how early it ended.

"I have to get ready for work," she groaned. He slowly drew his hands from her breast and thigh, and she wished he didn't. When she left, he didn't touch his breakfast. He stared at the ceiling, brow furrowed like was considering something.

Isabelle's mind lingered on that moment while she got ready and drove to work. This was supposed to be a day off. Thankfully, one of her friendly coworkers was called in too. On their lunch break, they took turns complaining about having to work on a Saturday. As was common for them, the conversation eventually moved onto more salacious topics. She confessed to Isabelle that she had anal sex with her husband as a birthday gift, even managing to orgasm from it.

Jealousy was written clearly on Isabelle's face. Despite her best efforts, she could never cum from backdoor penetration. Her friend gave some advice, not that she could try it out given the stipulations of her chastity contract. Still, Isabelle couldn't get the idea of it out of her head. She considered how Nathan would react if she could or if she couldn't, and how it might factor into chastity. As the day went on, it sent her down a spiral of horny, shameful fantasies about her son.

Nathan wasn't there when she got home, which she half-expected. She went to her room to change for her jog, pulling on a sports bra, tank top, and tight leggings. Alone with her thoughts, she stood in front of the mirror. She had been debating whether or not to ask Nathan about anal, and picturing the conversation made her fingertips cold.

'I wonder if he's gotten bold enough to go for it, or if he'd enjoy it. Would he call me Mom while we fuck? I wonder what position he prefers. Does he like eye contact, or would he want to be behind me?'

As she considered the possibilities, she squeezed her ass. Her grip was so much weaker than his.

Her endless stream of horny thoughts caused her to gradually shift gears. Isabelle leered at her reflection, assaulting it. She loved to see herself as a toy made to give and receive pleasure. Her best orgasms happened when she was absorbed in this mindset. Now, though, she couldn't receive pleasure. Not without his permission. If his orders and his touch controlled her, she realized, then she was his toy.

She pulled her leggings down. Two fingers ran along the underside of her chastity belt. They found where her asshole was encircled by a large metal loop. She turned and bent over, seeing in the mirror how inviting her ass looked while it was framed this way. It's been two weeks since she touched herself, and that includes back there. Testing if she had lost any skill, she drooled on a finger and started running it around her rim.

Remembering a well practiced routine, she clenched and relaxed the muscle, readying herself. Her finger slid in with a little more resistance than she had hoped. It didn't take long to ease into her hole, and another finger quickly followed. Standing bent over wasn't the easiest position, so she eased slowly into a squat without removing her fingers. Legs spread wide, she pushed as deep as her fingers could go. The pretense of merely testing herself had faded, and she fucked herself in earnest.

Her lust, finally uncontrolled, dominated her thoughts. Her pussy throbbed, and she tried to reach it with her other hand. She didn't even heed the reminder of her chastity belt, forcing a finger underneath it to just barely make contact with her clit. With no better option, she tapped it rhythmically. The sensation was so minimal, but two weeks of denial made up for it. She closed her eyes and started to moan, trying to hold onto every pleasurable twitch her body could make.

Today, she could have an orgasm. Nathan's going to unlock her and give his permission. She moaned his name, "Nathan... Nathan!"

"Isabelle?" a voice came from outside her door. She froze, clenching painfully around her fingers. Pulling her leggings back up, she went to open the door. Nathan was standing there. If him using her name wasn't enough, his eyes made it clear that he wasn't happy. "What were you just doing?" he asked, a false neutrality in his tone.

She confessed what she did. Something in the way he looked at her almost had her in tears, though she didn't understand why. Nathan crossed his arms and said, "I see. You've tested boundaries before, but you know that this is a clear breach of the contract you signed. After something like this, do you think you should be allowed an orgasm today?"

Isabelle was shocked at the question, looking for some sign that he didn't mean it. He had neither mercy nor flippancy on his face. She tried to voice protest, but it died in her throat. She looked at her feet, shaking her head as she began to cry.

He softened but showed no sign of breaking. "I've been doing a lot of thinking today. This is my fault. Instead of being your keyholder, I viewed myself as your son. I didn't see how horny of a person you are. That ends today. I won't allow any more slip-ups." He kissed her forehead and hugged her. Isabelle was slightly taller than him, but she felt so small. She held him tightly, whispering, "I'm sorry," over and over.

He broke the embrace and her repeated apology, saying, "It feels terrible to mess up, I know. This guilt can be eased if you want. A physical punishment helps you feel better. Do you want that?"

Isabelle stood before him in a closed and hunched posture. She gave a small nod. Following his instructions, she walked to the foot of her bed, pulled her leggings down, and bent over. Her upper body pressed into the bed, leaving her ass sticking up in the air. She felt his eyes behind her, and she wondered if he planned to punish her with his cock.

A loud smack on her ass made her yelp, the expectation of pleasure met with sharp pain. Each spank had enough force to leave a stinging sensation for a few seconds. He left enough time between each one for Isabelle to question whether or not he had stopped. The shame and disappointment in herself melted into the pain. When Nathan finally did finish, all she felt was a gentle, throbbing heat and a powerful submission.

They went to the bathroom. She stripped in front of him, happy to be so exposed to her keyholder. He unlocked her belt himself. That was the first time. She wanted that moment to last, but he ordered her into the shower. The water was frigid in her attempt to quell any lingering arousal. When she was finished, she stepped out to meet Nathan's gaze. He had a look she didn't recognize.

With a steady confidence, he said, "There's something I want to try with you before I lock you back up. It'll pair well with your intense sexual appetite. Do you want to try edging?"
