Valerie cracks first.

I watched my daughters often as I would bend their mother over the arm of the couch or as she would drop to her knees to service me on command. Sometimes they would meet my eyes and sometimes they simply stared at their mother, but neither of them gave much of an indication of what was going on inside their pretty heads.

One night, shortly after dinner, I was in my office going over some notes from a recent surgery I'd performed. The patient was doing fine but the patient was complaining that I'd made her breasts uneven. I had several photographs of the breasts in question spread out before me and I was positive I had gotten them right. I suppose I'll have to have them back for a follow-up. I sighed.

Judy was washing some dishes from dinner. She was wearing a sports bra and tight athletic pants, as she had plans to work out when she was finished. I noticed Valerie was standing nearby, watching her. They were speaking softly, and Judy was smiling. It had been a while since I'd observed such a conversation so I didn't interrupt.

However, when Valerie finally walked out to disappear upstairs again, I called her to me. She was wearing a pair of light sleeping shorts and a baggy t-shirt, torn in half across the middle to expose most of her flat stomach. It hung off one shoulder, revealing that she wore no bra. She looked ready for bed.

"Yes, Daddy?" She used to call me that all the time as a small girl, but stopped at some point during her teens. She'd taken to using it again suddenly ever since the day I first disciplined Judy in front of them. I hadn't really thought about it.

"Valerie. Have a seat, sweetie." I gestured to the chair opposite my desk and she sat down slowly, almost warily. It had been a while since I'd taken any time to check im with my girls. Perhaps that was wrong of me.

I continued. "I saw you were chatting with your mother. That looked like it went well."

She nodded, "Yeah, it was nice."

"What were you talking about?"

She paused, uncertain. "Um..."

"Now don't tell me you've forgotten. I want you to tell me." I kept my voice pleasant, but I'd become less and less patient ever since Judy became totally subservient. I simply didn't want to have to work to get my way in my own home.

She swallowed. "Well..." I could tell she was still searching for a way out of answering.

"Valerie." I lowered my voice, taking on the commanding tone I'd begun using with Judy. "Now."

She looked at me, swallowed again, and spoke. "I was asking her about all the changes we've seen in her lately. About her relationship with you. I asked her if she's happy."

So that was it. My daughter disapproved of the way I was running my house. "Of course she's happy. Why wouldn't she be?"

Valerie met my eyes and continued carefully in her soft voice. "Because she's basically your ****. Because you hit her all the time. Because you fuck her like a whore whenever you're in the mood. Because-"

"Enough." I said, and she stopped taking. "I hit her because I love her. Because that's the only way she will obey me, and I know what's best for her. It's good for her to obey me, do you understand?"

She didn't respond. She just started at me with her beautiful eyes, her expression the same blank mask it had been for months. Then, still softly, she said, "That's what Mom said, too."

I sat back in my chair as she continued, curious what she was going to say about Judy.

"She said that she's happier than she's ever been. She feels safe knowing exactly what you want from her, knowing exactly what makes you happy... What doesn't. She said... knowing you're here to keep her on her best behavior helps her be her best self. That she would be disappointed if you failed to discipline her for something obviously wrong." Her face was slightly flushed by the end, and her eyes had a strange intensity. She must have been furious.

"Well, there you have it. Your mother is happy with the arrangement and it's none of your business. Now, I see your mother is heading down to the gym. Are you going to join her? I know you and Melanie have-"

She cut me off, leaving me slightly speechless that she'd be so audacious. "Daddy, do you love me?"

Still shocked that she would interrupt me, I responded automatically. "Yes, sweetie. Of course I love you. You know that."

She nodded, as if to herself and then stood up. "I love you, too."

Then she turned and swept the entire contents of my desk to the floor in one motion. She grabbed my diploma off of the wall and smashed it to the floor, stepping on it repeatedly.

"Valerie! What has gotten into you?! Stop this immediately!"

She ignored me, throwing things to the floor and knocking things off the wall. She was like a child throwing a tantrum, but her face was calm, determined.

I stood up, stepping around the desk to reach her. "Valerie, enough!"

She persisted, pulling open drawers and shaking the contents to the floor before tossing the drawers themselves aside. She reached for the filing cabinet where I kept sensitive patient information, unlocked because I had been reviewing a file.

"That's enough!" I grabbed her roughly by the back of the neck and dragged her away from the cabinet, instinctively forcing her over my sturdy wooden desk to maintain my leverage. I brought my hand down hard against her pert ass in a slap sharp enough to sting my palm terribly. Almost out of habit, I spanked her again, then again, and a fourth time before I realized what I was doing and who I was doing it do.

Valerie was breathing heavily but she wasn't struggling. Her palms rested flat on the surface of my desk. Her feet shifted slightly as she felt the burning stings from my spankings."Daddy?" She said, her voice trembling. "Why did you stop? Don't you love me enough to punish me? We both know I deserve this."

The whole tone of our conversation suddenly made a lot more sense. Valerie wasn't disgusted with me. She was jealous. She wanted the same kind of attention I gave Judy. How could I have been so blind?

"You're right, sweetie. You deserve this." I said, resolving to treat her like the brat she'd become. It was my fault, really, for ignoring her discipline. I tore her shorts down to the floor and began spanking her again. She wasn't wearing any panties.

Valerie squealed as I assaulted her bare ass again and again, but I knew she needed it. Not for trashing my office. That was deserving of a punishment, to be sure, but she needed to be taught a lesson. She thought she could walk into my office and coerce me into giving her what she wanted, just like that. Well, be careful what you wish for.

I warmed her up with my hand until her entire backside was bright red and my hand stung. Valerie was panting and wincing occasionally. I had hurt her, but only a little. She was pretty tough as it turned out, and a spanking you enjoy is no proper punishment.

"Don't move." I ordered. She remained still as I moved around the desk to retrieve my brand new paddle from the drawer. I'd gotten it for Judy but it would work just fine on Valerie.

"Now that we're all warmed up, I'm going to punish you." She whimpered slightly but otherwise remained still. She'd probably thought we were done.

I pressed the flat surface of the paddle gently against Valerie's sore backside and she hmm'd softly. Its cool leather surface must have felt nice on her tender bottom.

Then I pulled back and spanked her with it hard enough to produce a cry of surprise. She jumped, but I kept one hand on her to keep her from trying to get up.

I hit her again, and then again. Her jovial attitude quickly faltered as she realized she was going to be spanked for real, that this was no game.

"Apologize." I said, and brought the paddle down again.

"I'm sorry!"

Again. "For what?"

She yowled. "For making a big mess!"

"Good." I paddled her again. "What else?"

"Uhh, for trying to escape and making you put this collar on me!"

This continued for another several paddles until she was crying, unable to come up with anything at all. "I don't know!"

I brought the paddle done one last time, her beautiful teen ass covered in bright and dark splotches and welts, and she started sobbing.

"I'm sorry for being a bad girl. For disobeying and disrespecting you. I won't do it again. I'll be good, like Mommy. Please, I promise I'll be good."
