Learning Curves 04

The next morning when I awoke, I could hear Kara moving around in the kitchen downstairs. I put on my panties, skirt and blouse before heading down. I found her in the kitchen eating her breakfast and getting ready for class.

She looked up at me and smiled, "There's my girl."

She was dressed in blue jeans and a sweater and was looking positively thick. Her powerful legs filled the jeans and her ass had a new curviness to it with all the muscle giving her a very sexy, full femininity.

I looked at her and smiled weakly back and pleaded, "Come on, Kara."

"Oh don't be like that, don't be grumpy. Come here, please." She said and gestured for me to come to her. I walked over to her and she encircled my waist with her arm and easily pulled me into her lap.

The contrast between us was getting clearer. My vegetarian diet of salads, yogurts, nuts, and vegetables had shrunk the size of my arms and legs so that I now had the body of a small woman. My skin had always been smooth and I didn't have much by way of curves but my arms were thin and soft, the size of her wrists, maybe smaller, and my legs looked not much larger. Because of all the butt lift exercises in class my ass had filled out nicely and had a roundness to it but that was the only real curve or muscle on my body. I felt small and nimble and had energy but I had noticeably reduced in size in the few months that I'd been enrolled in Professor Stanton's class. At the start of the year I wore a 30" waist but those old clothes hung off of me now and I had been reduced to a 26" waist.

Kara, on the other hand, had filled out so much that her already strong body was now becoming thick with muscle. Her biceps and traps were noticeable even when she was relaxed and she generally looked toned all over. Even in her sweater and jeans I could see muscle rippling under her clothes. Her arms were bigger than my legs and sitting on her lap felt like sitting on two iron plates. She had gotten so much stronger over the past month that she moved my body like I was a doll. Next to her I looked like her tiny companion. Her new strength had affected the rest of her body too: her face was flush with colour and her skin was clear.

She looked deep into my eyes.

"Did you like last night sweetie?"

Once again I gave her the submissive look that I'd been perfecting in class. "Yes, Kara. Thank you."

"Good girl. Thank me again."

"Thank you, Kara."

"Yes, but say it like a girl, and call me Master Kara."

I paused... this was going a little far, but then I remembered that really I had no choice. I was ensnared in every possible way: physically, intellectually, emotionally. She knew my secrets, she held me in her power, she could break me physically and emotionally. I gave in, raised my voice into a girlish register and said, "Thank you Master Kara."

She smiled a broad grin. "Good girl."

She spoke softly and deliberately: "I want you to do well in your classes and I think that you'll do your best when your under my guidance, under my supervision. Do you agree?"

"Yes, Master Kara."

"You know, Michelle, you have a lot of potential, but it was being wasted by your male self. But I think you could really excel in your new female role." I didn't reply.

She continued, "You might see what I'm doing as cruel or unnecessary but really... it's about bringing out the best version of you."

She stroked my leg with her hand as she spoke. I couldn't help but notice how large her hand was compared to my thin leg. Her fingers were strong and firm and she looked like she could wrap her hand around my thighs.

"I know this is who you are, Michelle, and it's what you want. You just would never get there unless I force it on you."

She held me there for a moment and I felt turned on as I felt my body raising with her breathing and her words... so true, so wrong.

Her breasts were pressed into my side, reminding me of the feminine power that lay beneath her muscle and power. She looked and me and then continued, "Isn't it wild to think that you're older than me? I was reading some of the stories that you like to look at and... well, I think I understand what you like. And honestly, I think I like it too."

I was both intrigued and concerned, "What parts?"

She smiled and ran her finger along my leg possessively, "Well, I think you like the reversal, the transformation of gender roles, being dominated by a younger woman, someone who should be smaller, weaker, and dependent but who is taller, stronger, and dominant... Am I right?"

"Yes," I said, weakly.

"It makes you feel, conquered, controlled, emasculated. And you like that, don't you?"

"Yes, Master Kara."

"And you like how I treat you don't you Michelle?"

"Yes," I repeated.

"It's kind of a perfect situation for you. I'm the girl next door, younger, but I surpassed you so easily, made you mine, controlled you."

"Yes," I said, feeling submerged within the erotic situation.

"And maybe you want me to be your girlfriend?"

Of course I wanted that... "Yes..."

She smiled and gave me a gentle kiss. She then gave me a knowing look in my eyes before continuing, "But really, secretly, you want me to be your boyfriend."

I was silent, "I..."

She then gave me a forceful kiss where her tongue invaded my mouth. She placed one of her hands on my breast and squeezed before pulling away.

"No need to argue or explain. I'm going to be your boyfriend from now on."

I was breathless but whispered, "Boyfriend?"

She smiled at me, "I love how you play coy... it's what really convinces me that you're a weak girl underneath all of the pretend masculinity. You know you want it but you're too scared to say what you really want. You want me to force it on you, to make you feel like it was my idea and you're just obeying like a good girl. You're like any slutty girl... you want your man to force you to do it."

She placed her hand around my throat and gave it a gentle, firm squeeze before continuing. The strength was incredible, she could've snapped my neck. I let out a tiny, weak moan.

"I've read the stories, Michelle. I know what you want. A surrender, a submission, an acknowledgment that despite all the advantages you had as a man, more muscle mass, privilege, all that stuff, despite it all, I've taken charge of you, I've taken the dominant role."

She squeezed my throat again, gently but firmly, "I'll be the man... I'd suggest that we could wrestle for it, but I know you'd love that and we both know how it would go... And, besides, you make such a sweet little girl. Remember what you said last night," and she mimicked my comments from the night before, "Please Kara... be my man... Uhhh... Uhhh," she said with a wicked grin.

I blushed but was also getting turned on. My chest heaved and I could feel my nipples hardening just as I could feel an erection in my panties.

Kara noticed it to because she looked down and said, "See, sweetie. Your mouth says one thing, but your body says something else."

She grabbed my dick in my panties, "It says, I want to be Kara's girl. I want Kara to be my man." She squeezed my dick which was now rock hard. I was unbelievably aroused at her words. "Just like in all the stories you love. Where a woman takes your place, makes you her girl. You want that, don't you?"

I was almost breathless with desire, "Yes, Kara. Yes, please be my man. Be my boyfriend."

"You need me to hold your leash with a firm hand, right sweetie?"

"Yes, Kara."

She squeezed my dick again, "Maybe I should rip this thing off you? Take it away and make it my own?"

She squeezed my dick again before kissing me firmly on the mouth.

"I'm making you into a far better girl than you ever were as a man, aren't I?"

"Yasss..." I felt so aroused, being held in her strong embrace with her hand wrapped around my cock.

She released my dick and said "OK, sweetie. You can be my girlfriend." And with that she stood up, placing me on my feet and stepping away from the table. I almost fell over, I was so turned on, but she simply walked away and said, "Come and sit next to me in class today" and then walked out of the kitchen.

I was so turned on I stumbled around the kitchen for a second, trying to recover myself. After Kara left our apartment a few minutes later, I ran to the bathroom and masturbated furiously, cumming as I recalled the feeling of her strong thighs and her words to me. She knew my deepest fantasies and was pushing all of my buttons. I was powerless in her grasp and I had to acknowledge to myself that I loved the entire experience.

I quickly cleaned myself up and changed into a pair of yoga pants that Kara had got for me. I smoothed out my penis so it wouldn't show any lines and put on a light green top. My ass was more and more pronounced and really stuck out in the pants. After getting dressed, I headed to school.

That afternoon, I found Kara in class. She was sitting in the front row in the same outfit as before. She had saved a seat for me and waved at me as I approached. As I sat down she said, "I've got a surprise for you sweetie. Close your eyes."

I did as she instructed and felt her placing something around my neck. I opened my eyes and saw that she had given me a gold necklace with the word "Kara's Girl" at the bottom.

"This is for you, sweetie. I want the world to know you're my girl."

I was embarrassed as a group of other women nearby were listening.

I spoke quietly "Kara, I..."

She smiled at me and said in a loud voice, "Oh don't be shy Michelle. You asked me to be your man, to be your protector, and I will. But you need to wear this to show the world, you belong to me. What do you say?"

My cock was rock hard in my yoga pants and my heart was racing.

A girl sitting behind us said, "That's so nice. Kara is so nice to you Michelle."

I felt a mixture of humiliation and arousal and I softly said, "Thank you, Kara."

"Thank you, what?"

"Thank you, Master Kara."

Kara smiled leaned in and kissed my neck gently and whispered, "Your neck is so feminine. You're such a sweet girl, Michelle. You're welcome. Now, will you go and grab us coffees before class starts?"

I did as I was instructed and left the class to get the coffees. Standing in line, I tucked the necklace into my shirt, feeling somewhat embarrassed.

I was waiting for the coffees when I felt someone press into my back and whisper into my ear, "Hi, slut."

I recognized the voice -- it was Stacey. I turned to face her and was somewhat surprised that she was dressed quite femininely, in a pink dress with a cardigan over her shoulders, and matching heels. In her heels she stood at least 3" taller than me. She was actually really pretty -- a kind of classic blonde! Not at all the sweaty woman I'd seen in class the previous day. I must've worn my shock quite clearly on my face because she looked at me suspiciously before speaking.

"What's the matter? Didn't expect to see me like this?"

"It's just--- wow, you look... great."

She really did. Her blonde hair was styled down her back, her neck was thin and graceful, and her breasts were full. As we stood there talking, lots of guys were checking her out when they walked past. The only sense of her muscular body was in her legs and the rounded shoulders apparent just above her cardigan. The rest of her outfit was designed to present an image of femininity and perhaps to hide her powerful body.

She smiled at me slightly as she watched me survey her body.

"Thanks. I know. I don't just wander around in gym clothes all the time. I like to get dressed up and look my best."

She placed a firm hand on my shoulder and then said, "But don't let this outfit fool you, slut. I may look like a nice girl, but I'll still fuck you up." She squeezed firmly and I could feel the strength in her arm.

"And remember, I want you at my apartment this evening."

"Oh, Stacy, I'm not sure that I shou..."

As I spoke she squeezed my shoulder, sending a bolt of pain up my arm. "Ow..." I cried out. She didn't take her hand away.

"I'm not interested in your excuses, slut. I want you at my place at 7pm sharp to clean. If you're not there, I'm going to kick your ass where everyone can see."

I looked at her blankly. My brain was conflicted as I took in this image of this girl who exuded sweet femininity and who was calling me a slut and forcing me to clean her apartment. Kara had told me not to do this but the pain in my arm made me blurt out "Yes, Stacy... I'll be there," without thinking

"Good slut," she smiled at me again -- the way she could transform from angry, aggressive woman to a seemingly demure and gentle girl was scary. "Oh, and since you're here, you can buy my coffee."

She gave me her order and I followed her instructions, ordering her coffee and the coffees for Kara.

Standing there waiting for the coffees, I wasn't sure what to do. Kara would be pissed if I went to Stacy's apartment but Stacy would be pissed if I didn't. I was caught between these two powerful women and didn't know what to do. I was being pulled in two directions but what did I want? Did it matter? These thoughts ran through my head as I collected the coffees. I returned with them just in time for the Professor to start the class. She eyed me coolly as I slipped into the seat next to Kara.

"I want to commend the class on what you've achieved so far. Equity is a complex concept and we might be inclined to think that it simply requires equaling out opportunities or results. No! Equity requires more than that: it requires re-balancing the scales. To that end, the class is doing very well. I can see the way that Kate's group is learning to step back, to give space to my group. Excellent work girls and women. You've all learned so much and come so far."

As the Professor was talking, I was lost in my thoughts concerning what to do about Stacy. Kara had told me to keep away from her but she was so forceful. Truth be told, there was a part of me that wanted to obey Stacy, to clean her apartment like she told me... I had to admit, it turned me on. There was also a part of me that was legitimately scared about what Stacy might do if I disobeyed. What would Kara do if I told her about the situation? Would I be in trouble for speaking to Stacy at the coffee shop? I felt like I was screwed no matter what I did.

The class was excited to learn what the special event was going to be and as we left the lecture hall we were all wondering what the Professor had in store. I was walking out of the hall and found myself holding onto Kara's arm: it was thick and powerful and I felt safe clutching onto her firm upper body.

Kara looked down at me with a smile, "What's up, sweetie?"

I bit my lip, "Well, I know you had plans tonight with your friends, but I was thinking maybe we could have dinner together?"

Her expression was unreadable for a moment, and then she leaned in and whispered in my ear, "I'm sorry, but I'm going out with my friends. We can have a dinner another night."

I nodded, trying to keep the disappointment out of my voice, "OK, sure. Have a good time, Kara. I'll be fine at home."

But I wasn't fine. I had hoped that being with Kara would put the thought of Stacy out of my mind but this just opened a new possibility to seeing her. After Kara and I separated, I felt a thrill run through me at the thought of going to Stacy's place. It was a dangerous and exciting prospect. I had the perfect cover now, and I knew that Kara would never suspect a thing. As the day went on, I found myself getting more and more turned on by the idea of going to Stacy's place and serving her. I had never felt this way before and I knew that Kara would be furious if she found out. But there was something about Stacy's dominance that called to me, something that made my body crave submission. I knew that Kara would be furious but I felt intoxicated with this possibility and I couldn't resist.

That evening I showed up at Stacy's door at 6:55 and knocked. There was no answer so I knocked again until I heard her call from behind the door, "Hold on, hold on!"

Finally she opened the door and looked at me with a smile. She was wearing a bath robe and had clearly just come out of the shower as her hair was up and she had just applied makeup. I had never seen her this done up and I was amazed at just how beautiful she looked -- even better than this afternoon. With her high cheekbones, blue eyes, slender nose, and plump lips, she was a classic blonde beauty -- made all the more apparent by her makeup.

"Come in, sissy" she said at full volume so anyone nearby could hear.

I walked into her apartment -- it was comfortable and tastefully furnished but small. She let me take in my surroundings and then I realized she was staring at me. I felt both intimidated and enthralled by this imperious beauty.

"I'll want this entire place cleaned by the time I get back. That includes the dishes and vacuuming and cleaning the bathroom."

"You're... you're going out?" I asked. I had hoped that I would have at least been able to spend time with Stacy. I had to admit that the possibility of hooking up with her was at the front of my mind.

"Um, yes. I have a date. Not that it's any of your business."

I felt humiliated. Here I was thinking that this girl's aggression expressed a strange form of interest in me when in fact I really was here just to clean her place while she went out on a date. I had lied to Kara to clean this girl's apartment. How low had I fallen?

She gestured towards the couch and said, "And when you clean, I expect you to be in your uniform."

I looked at the couch and saw was a French maid's outfit. I swallowed before asking, "Is that really necessary?"

She looked at me fiercely before speaking in a firm voice: "Yes, it is necessary. Now get changed you little slut."

I scampered over to couch and she left the room. "Come into my bedroom when you're dressed," she shouted.

I slowly took off my clothes, folding them neatly and placing them on her coffee table, before picking up the costume. I noticed that it was a size small as I pulled it over my head. I felt ridiculous although I had to admit that the costume fit me very well. This evening was turning into one humiliation after another but I went through the process of putting on the costume, straightening it so it fit properly and then walking into her room.

When I walked into Stacy's bedroom she looked at me and smiled. "That suits you, girl." She then dropped the robe and stood in front of me with looking equal parts haughty and attractive. My eyes shot open -- her body was amazing and she stared at me with an imperious, arrogant look. Her breasts were quite large, they had to be DD, and her stomach was flat and smooth but with a hint of abs. Her shoulders were round but feminine and I could see the hint of veins and wiry musculature in her arms. Her calve muscles flexed as she stood but they were subtle and graceful. She was incredibly attractive: I had no sense of her proportions but she looked like a living Barbie with curvaceous hips, large breasts, yet with a layer of muscle atop her femininity.

Her thighs were not close to being as big as Kara's but were firm, tan and layered with muscle, like a gymnast. She was clearly very strong but her muscles lay beneath her smooth, golden skin. Her ass was round and firm -- with her combination of muscles and feminine curves, she was like a fitness model or porn star. She put her hands on her hips and looked at me.

I felt like a servant in her presence and, really I was. I was smaller, weaker, under her control. I was clothed but she was clearly the one in charge.

"Well, girl? I'm not standing here for you to gawk at me." And she snapped her finger. "Make yourself useful. Dress me!" she nearly shouted and I scurried over to her, looking for clothes.

Standing next to her felt oddly humiliating: she was an inch taller than me and while she was naked and I was dressed in the maid's uniform, it felt like she had all the power. I was humiliated, emasculated, completely robbed of any masculinity yet also completely aroused. I was drowning in desire and it took real effort for me to pull my eyes away from her incredible body. I looked around and she sighed before pointing to the bed. I saw her clothes lying at the bottom of the bed and moved to pick them up.

I stared at the pile of clothes for a second before she said, "Underwear first, you dumb cow."

I picked up the black silk panties and handed them to her.

"Put them on me! Jesus ... are you that stupid?"

I looked at the silky black underwear in my hands and felt intense humiliation and arousal at what she was asking me to do. To be so servile... felt wrong and right. I licked my lips and sank to my knees in front of her.

She raised one foot and I held out the panties for her to step into. She then stepped into the other leg and I raised them up her legs and smoothed them out on her glorious ass.

"Good girl. See, you can be useful if you follow instructions."

Next was a short, plaid skirt on her bed and I again, sank to my knees to pin it on her waist.

As I was about to do so, Stacy placed her hand on my forehead and pushed it roughly forward, forcing me to look up at her.

"Before you do that, show me some appreciation. I want you to kiss my ass and thank me for allowing you to serve."

I knew better than to argue so I smiled passively and submissively.

I moved, on my knees to face her back and leaned to the back of the black panties, and kissed her ass cheek gently. I then looked up at her, "Thank you, Ms. Stacy, for allowing you to serve."

She smiled down at me, like a benevolent bitch: "You're welcome. Continue."

I placed the skirt around her body and zipped it up.

"Heels next, please."

I found the heels at the foot of the bed: 3" black stilettos. I picked them up, knelt in front of her and placed them on her feet, one by one. Her toes were small and delicate but I could see the strength in her legs as I slid the shoes onto her feet. I then stood up and picked up her bra to put it on her. It was a black silk push up bra and I noticed it said 34DD. I gently slid it around her body before clasping it on her back.

As I clasped the bra I felt the muscular power in her back and once again I felt the contrast between us: her lithe female body, her taut muscles, wiry and firm, her large breasts and her feminine power had all overwhelmed my weak failure of masculinity. She could break me with one arm, seduce me with another -- I was powerless in her alpha presence. Her back muscles were tight and knotted and I must have been so entranced by the power of her body, so much so that I must have accidentally brushed her sizable breast.

"Ew, keep your hands off my tits," she shouted and turned around.

In her heels she was 4" taller than me -- a vision of feminine power and muscles. I could see the abs in her stomach flexed and in her heels the muscles in her thighs stood out firmly. I tried not to stare but I couldn't stop my eyes from glancing at the glorious full breasts, in the black silk bra, dancing just in front of my face.

My dick was hardening as she stood in front of me.

"I'm not some dyke who wants to fuck you, slut. I'm going out with a MAN tonight. Do you think you're some kind of man?" she said, with her hands on her hips revealing taut biceps.

"No, no Miss Stacy."

"Would a man come and clean a girl's apartment and then dress her for a date?"

"No, Miss Stacy."

"Look at me when I speak to you."

I did as she instructed, taking in the muscular power of her body, the swell of her breasts, the perspiration on her chest, the taut muscles of her legs. I wanted to pull out my dick, fall to my knees, and worship her.

Her eyes drove into me: "If you were a man... you'd try and have your way with me. A real man would force himself on me. But you're not a real man are you?"

"No... no Miss Stacy."

"You're a little sissy. My little servant girl."

"Yes, Miss Stacy."

"Good girl."

She looked down at me and smiled a wicked smile. "Maybe I'll bring my man home tonight so you can see what a real man is like. Would you like that?"

I looked up at her with weak pleading eyes, "Please... please no."

"Oh sweetie. You might like it."

"No, Ms. Stacy, no."

"You could serve us while we fuck like our little maid slut. Doesn't that sound nice?"

"Please, no..."

She placed her hand on my chin and said, "Well if you clean the house very well, then I won't make you slut it up for my date. But if I come home and it's not absolutely perfect, then next time you won't be so lucky. OK, slut?"

"Yes, Ms. Stacy! Thank you." I said, with humiliating readiness to please and serve.

"Good girl."

She stared me for a second before flexing her biceps. The transformation from imperious cheerleader to amazonian goddess was instantaneous and I could feel my jaw slacken and my dick move in response to the image of female muscular power before me. She was a goddess before me and my brain was scrambled as I took in her perfection.

"I'm more of a man than you'll ever be, aren't I?"

I was speechless with desire. I simply reached up and wrapped a soft hand around her large, firm bicep; I let out an involuntary moan.

She smiled and stepped away. "I'll expect this place cleaned from top to bottom. I demand perfection."

"Yes, Ms. Stacy."

I watched her leave, feeling a strange mix of arousal and fear. The door closed with a thud, leaving me alone in her apartment. I took a deep breath and turned my attention to the task at hand. The place was surprisingly tidy, but I knew that any imperfection would be met with Stacy's wrath. I set to work, scrubbing the floors, dusting the shelves, and cleaning the kitchen until it gleamed. The scent of lemon cleaner filled the air as I moved from room to room, ensuring not a single speck of dust was missed.

As I worked, my thoughts kept drifting to Kara. What would she say when she found out? I knew she would be mad that I had gone against her wishes. Part of me thought that this was my life, I make my own decisions, and I should do what I wanted. If I wanted to see Stacy, even as a submissive maid, then that's my choice.

But another, truer, part of me knew that Kara was right and she was in charge of my life now and that I should obey her. She detected something in me, some deep truth, that I needed to be controlled by a dominant woman. I fingered the necklace that hung around my neck and I knew that I really did want to be Kara's girl. Kara's words echoed in my mind, turning me into a nervous wreck as I moved around the apartment. I had never felt so small, so utterly at the mercy of two such powerful women.

As I finished up the living room, I couldn't shake the feeling that this was a pivotal moment in my life. I knew I had to come clean to Kara. I couldn't keep this secret from her. The fear of her wrath was nothing compared to the fear of losing her trust. I took a deep breath, changed out of the maid costume, gathered my things, and left Stacy's apartment with a new resolve.

Walking back to the apartment I shared with Kara, my heart raced with anticipation. What would she say? Would she understand? As much as I dreaded the conversation, I knew it was the right thing to do.

When I stepped through the door, Kara was in the kitchen, her back to me. She was dressed in her usual workout gear, her muscles bulging and powerful. She turned around, a look of confusion crossing her face as she took in my flustered state. The sight of her only made me more nervous. I swallowed hard and began to explain.

"Kara, I need to tell you something," I said, my voice quivering. She raised an eyebrow, a hint of amusement playing at the corners of her mouth. "I went to Stacy's tonight. She made me clean her apartment and wear a... a French maid's outfit." The words tumbled out of my mouth, each one heavier than the last.

Her expression shifted from amusement to anger in an instant. "You went behind my back?" she growled. "You disobeyed me?" Her muscles tensed, and the room seemed to shrink around her imposing figure. "What the hell were you thinking, going to see that bitch?"

"I... I didn't mean to," I stuttered. "I just... I wanted to tell you everything. I'm sorry."

Kara's eyes narrowed, and she took a step towards me. "You're sorry?!?! You lied to me. You disobeyed my rules."

"Yes, Kara," I murmured, dropping my gaze to the floor.

"I knew you were incapable of managing your own life but this..." she paused, "this is incredible. I can't believe you would disobey me like that."

I looked up at her pleadingly, "But, can't I choose who I see?" I said weakly.

She stepped close to me and I could feel the power of her body as she stood over me.

"No, you cannot" she said firmly. "I decide for you." She grabbed hold of my arm and squeezed it firmly. "You're weak. You're small. You're my responsibility and you will obey my rules."

I was silent.

"Do you understand?"

I looked up at her again, "Yes, Kara... I'm ... I'm sorry."

She looked down at me with fury in her eyes but I could see that she was beginning to sympathize.

"I didn't know what to do! I fucked up but... she's so forceful."

She looked at me silently before saying. "Yes, you fucked up but it just shows me that I need to have a firmer hand when dealing with you ... I'm going to have to punish you."

"You are? How?"

"I haven't decided yet... But I'll punish both of you. Fucking Stacy... She'll get what's coming to her." Kara's voice was like thunder, and I knew she was more than capable of backing up her words with action.

"Kara, please," I begged.

"Quiet," she barked. "You're mine. You both need to be punished, and she needs to understand that you're not available for her games."

The tension in the room was thick as she considered her options. Kara's jaw clenched and her biceps bulged. I stood in front of her like a scared child awaiting her decision. Finally, she stepped away from me and picked up her phone, and called Stacy.

"You're going to regret the day you laid your hands on my girl," she hissed into the phone, her voice low and menacing. "Get your ass over here right now, you bitch, or I'll come to you and it won't be pretty."

"Yes, I'm serious. Get over here now or you'll regret it." And with that Kara hung up.

Kara looked at me fiercely, "Get in your room now. Undress and wait for me."

I began to say something but decided otherwise and nodded hastily, scurrying to the bedroom. I took off my clothes and sat on the bed. What had I gotten myself into?

The house was silent aside from the sound of Kara moving around and lifting weights.

After about 10 minutes I heard someone knock weakly at the door and Kara move to the door. There was some shouting that I couldn't make out and then a sound of tussling in the living room. I sat in terrified silence in my room before I heard, "Come out here please" from Kara.

I quickly slid myself into a pair of panties, a skirt, and a top before stepping out of the bedroom.

I walked into the living room to see Kara was sitting on the couch in a black tanktop and shorts, revealing her large, powerful muscles. Stacy was in the same outfit that I had dressed her in and she was splayed across Kara's lap with her skirt pulled up over her ass and her arms held behind her back. For all her strength and dominance, she looked absolutely puny compared to Kara, who was pinning Stacy's wiry arms behind her back with one of her powerful hands.

Kara looked at me intensely, "Stacy has something to tell you, Michelle."

Stacy was on the verge of sobbing and looked at me with pleading eyes, "I'm ... I'm sorry, Miss Michelle, for what I did to you. I know you're Kara's girl and I was wrong to do it."

Kara looked from me to her and said, "And you'll never bother Michelle again, right?"

Stacy replied, "No Miss Kara."

Kara smiled and then raised her hand and proceeded to spank Stacy with intense ferocity. After a few blows, Stacy cried, whether from the humiliation or the pain, I don't know. Kara said, "I want you to thank me for punishing you, Stacy," firmly, not breaking her rhythm.

Stacey, through her sobs, managed to say, "Thank you Miss Kara for punishing me. I deserve it and I'll never do it again."

Kara spanked her a few more times, her muscles flexing and releasing with each slap. I felt a mix of pity and excitement watching her.

Then she stopped and caressed Stacy's face and hair, "Do you understand why I have to punish bad girls?"

Stacy said, "Yes, Miss Kara. I was bad. I'll never do it again."

Kara said, "OK, then stand up."

She did so and I had to admit I was still impressed with her amazing body as she stood up and stepped away from Kara. Watching her pull herself off of Kara's lap, she still looked incredible.

Kara then looked at me and said, "Your turn, Michelle."

I was shocked -- I felt my stomach drop as I realized she was going to spank me as well. I assumed I would be spared... I stepped over to her and she pulled me over her knee and roughly pulled down my panties.

I felt her strong legs below me just as she brought her powerful hand down on my ass and it burned with intensity. I shook with pain. She did it again. And again. And again. Each smack brought forth a new wave of pain and a new yelp from my mouth. I couldn't even feel embarrassment, I could only feel the pain -- I began to cry, the pain mixing with the emotional overload of the situation. The sound of her hand connecting with my flesh echoed through the room and I knew that she was taking this seriously. It was like she was branding her ownership onto my body.

"You will never lie to me again, do you understand?" she said, her voice firm and unwavering.

"Yes, Kara. I'm sorry. I'll never lie to you again," I whimpered.

"You are a bad girl!"

"Yes, Master Kara. I'm sorry. I'm a bad girl."

Kara spanked me until my ass was a deep shade of red and I was crying uncontrollably. I felt so small, so utterly dominated by her power. When she was finished, she helped me to stand and then looked at me.

"Stand there for a minute."

Both Stacy and I stood in front of Kara like two abashed children. We held our hands in front of her and she sat there assessing us. My eyes traced the thickness of her thighs, the tight muscles of her stomach and her biceps and forearms, swollen with the work of slapping our asses.

"Have you both learned your lesson?"

"Yes, Master Kara," we said in unison.

"And you'll both be good girls from now on.

"Yes, Master Kara," we repeated.

She smiled. "Good. Now the two of you can clean this apartment."

We looked at each other, confused.

"In the nude," she added.

My face turned red and Stacy looked at me, wide-eyed. But we knew better than to argue with Kara in this state. We both began to undress slowly, feeling the heat of Kara's gaze on us. The room was silent except for the sound of fabric sliding off our bodies. When we were both naked, she nodded in satisfaction.

"Now, clean the living room together," she ordered. "And remember, no talking to each other unless you're discussing the cleaning. You're not friends; you're just two sluts who need to learn their place in this house. Got it?"

We both nodded meekly, and Kara leaned back into the couch, watching us intently.

As we began to pick up the mess we had made earlier, I couldn't help but feel a mix of humiliation and arousal. Stacy's body was stunning -- muscular yet feminine, with curves in all the right places. I tried not to look at her, but our eyes kept meeting, and I could see the same confusion and desire reflected in hers.

Once the living room was spotless, Kara inspected our work, running her hands over the surfaces we had cleaned.

When she entered the room, her muscular body glowed with a sheen of sweat. Her biceps bulged and flexed with every movement, and her abs looked like they had been carved from marble. Her legs were thick and powerful, a testament to the countless hours she spent in the gym. Her breasts, while not large, were firm and high -- I felt positively tiny in comparison to this amazon. Standing nude in front of her while she surveyed my work made me feel like her servant.

She was thorough, making sure that every inch was up to her standards. After she was satisfied, she turned to us and said, "Good girls. Stacy, I don't ever want to see you talking to my girl again, do you understand?"

"Yes, Miss Kara," Stacy replied, her voice shaking slightly.

"And you, Michelle," she continued, turning to me, "You're to stay away from Stacy unless it's to serve me or to do as I say.."

I nodded, feeling a strange mix of relief and sadness. Kara's words stung, but I knew she was right.

"Good," she said, standing up. With that, she turned to Stacy and said, "You can go now. And remember, you're never to set foot in this apartment again, is that clear?"

Stacy nodded and whispered, "Yes, Ms. Kara," quickly grabbing her clothes and rushing out of the room, her cheeks flushed with embarrassment. I watched her leave, her breasts bouncing against her fit body, feeling a pang of something I couldn't quite place. As the door closed behind her, Kara looked down at me, her expression unreadable.

"I'm sorry, Kara," I whispered, my eyes cast down.

She stared at me in stony silence.
