Big Sister’s Submission Part 2

(Bobbi wants to end her current situation with her sister but Becky has other ideas)

I was restless on the floor of my own room, my head on a pillow and a blanket thrown over me. Otherwise, I was naked on the soft carpet.

My bed was currently being used by my 15-year sister Becky, who had caught me watching a lesbian femdom video last night.

I confessed to my younger sister than I wanted to be under the control of another woman and she offered to help, possessing more domineering tendencies.

I was able to get a few hours of sleep in between thoughts of actually submitting to a female authority figure. I just never thought it would be to my younger sister.

I couldn’t think of her as a mistress but I did trust her. We were close growing up and could tell each other anything. It was embarrassing confessing my feelings and she made it even more embarrassing by having me get naked and call her mistress.

I already had an assignment as I woke up on the first day of my submission, I had to stay naked while I bathed and then had to go to the kitchen for two glasses of orange juice. She also asked that I bring a bowl.

The first part was easy, since I didn’t normally wear anything when I showered. But when I dried off, I realized that I would not have any covering going to the kitchen.

What if somebody caught me? What would I say? What would I do? This caused all sorts of humiliating thoughts. My face felt like I was on fire. It was also hot in another spot of my body.

I opened the bathroom door slowly, making sure as to not disturb anyone else in the house. I crept out the hallway and then used the wall to slowly move down the stairs one … step … a … time. I reached the bottom and turned to survey an empty living room, an empty dining room and an empty kitchen.

Now that I was downstairs, I started moving a little faster and was able to open the refrigerator, pour two glasses of juice and grab a bowl, Just as I turned for the stairs, I heard our neighbor’s door open and shut. I froze, hoping to become invisible. I heard a car door opening just outside the window. Moments later, the car started and I heard it back out of the driveway.

I don’t think anyone saw me since it didn’t take long for the car to leave. I didn’t dare turn around but I did start to step livelier, heading up the stairs without spilling the juice or dropping anything.

I reentered my room, placed the juice carefully on the floor next to me and assumed the position established by Becky: kneeling, with my hands on top of my head. The longer I knelt there, the more embarrassed I became and the warmer other areas of my body became. It was humiliating and exciting at the same time.

I was beginning to question this whole situation. Sure, we were close friends but I didn’t think it was right that my younger sister suddenly had so much power over me. I had to get out of the arrangement. It was fun for a night but this couldn’t go on.

Becky sat up in bed and stretched her arms out a few minutes later. She rubbed her eyes and yawned. Then she looked down at me, kneeling, naked, on the floor.

“Good morning little one,” she said.

“Becky, I’m having second thoughts about all this,” I said straightaway. “I don’t want to do this anymore.”

Becky didn’t say anything for a few moments. Then she started walking slowly around me and spoke gently.

“Why Bobbi, I am surprised. I see you followed my orders and brought us orange juice and you’re in perfect position. You only made one mistake and called me by the wrong name. You don’t want to get into any further trouble.”

“But Becky, I mean, Mistress, I don’t feel good about this,” I whined.

“Such a shame little one. You are going back on your word. What am I supposed to feel? You longer like me? That hurts my feelings. Besides, you have already committed yourself and now you think you can break the rules?”

I couldn’t say anything. I felt bad that she felt slighted. I didn’t mean anything other than to just go back to normal.

“OK little one, if you want a choice, then you’ll show me by your actions,” Becky said. “I’m going to pick up these glasses of juice. One is for me, of course. The other one will be your choice. You can stand up and take the glasss like a big girl, or you can slide that bowl in front of you and ask me nicely to pour it into the bowl for you to lap up with your tongue. Doesn’t that sound nice?”

I looked up at her, then at the glass and then at the bowl. The longer I thought about it, the more I convinced myself that I should honor our agreement, At the same time, I felt a fire building up within my vagina. All my resistance left me.

“Please Mistress, pour the juice in my bowl so I can lap it up.” Those words came out of my mouth before I could think about them.

“Good girl,” Becky said as she got off the bed and poured the juice into the bowl. “Now, little one, you can only use your tongue to lap up the juice and I want the bowl nice and clean.”

She patted me on the head and returned to the edge of the bed to watch her older sister drink out of the bowl. She was smiling and emitting sighing sounds and other noises that reflected her contentment.

I wasn’t feeling anything close to contentment. Putting my hands behind my back, I knelt over the bowl, stuck my tongue in the juice and started lapping at it, getting as much on my face as into my throat. I felt so small compared to my sister. With her on the bed and me on the floor, the difference between us felt enormous. My face glowed red with shame and embarrassment as I was obeying her order. At the same time, the warmth inside of me was also growing into something like a need for sexual fulfillment. Not that I wanted to have sex with my own sister, but if I had a girlfriend at the time, I’d definitely do something about it. Now I just wanted to find some alone time.

Finishing the bowl was hard work. I had to put my whole face into it to make sure I got everything. When I finished, I returned my hands to the top of head and knelt up, waiting for Becky.

She seemed a little spaced out bt when she realized I was done, she looked at me and could not stifle a laugh.

“Little one, your face is a mess,” she said. “Don’t worry, your mistress will clean it up for you.”

Becky used the blouse I was wearing yesterday and wiped my face much like a mother would do with a baby, including making cooing sounds. “There, there, much better little one. Now you need to thank mistress.”

“Uh, thank you Mistress,” I uttered.

“What for?”

“For wiping my face?”

“You can do better than that little one,” she said. “Think about what you’ve already accomplished today and then thank me again.”

It took a minute before it came to me. “Thank you, Mistress, for allowing me to take a shower, walk naked to the kitchen and brin back orange juice. Also, thank you for allowing me to drink out of the bowl and finally, thank you for cleaning the mess off my face, Mistress.”

I was proud of myself for thinking about everything and even knelt a little higher.

“Oh, my poor babygirl, you missed the most important thing. You have one minute to remember.”

I slumped down again, knowing I had just let her down. I didn’t understand how I had let her down and the minute was up before I could say anything.

“Well, I suppose you’ll start to remember as I deliver your punishment. Come up her and lay face down over my knee.”

“Please Mistress, I’m sorry I can’t remember. I’ll be better, honest. Give me another chance, please Mistress.”

“Up and don’t delay unless you want further punishment little girl.”

I quickly rose to my feet and then laid down over her lap, my breasts hanging down over one leg and my pink parts wedged into another leg. Then, she started rubbing my bottom. It felt so nice.

“Okay, little one, mistress will now explain why you earned this spanking. First, you failed to call me Mistress.”

The first hard slap on my butt came while she said that.

“Second, you wanted to run away from your contract.” The second and third slaps met their targets.

“And then you failed to apologize to me for your silly antics and never thanked me for allowing you to continue to be my pet.” She reached 10 during that time, each one seemingly harder than the last. My bottom was sore and I couldn’t keep still on her lap. My eyes were tearing but there was no way I was going to cry.

I thought it was all over as she rubbed my butt some more after 10 slaps. But she held me down with her left arm and suddenly delivered 10 more spanks in rapid fire, even hitting the same spot few times in a row. It felt like small daggers nailing me and the not-crying thing went out the window. I was balling loudly, my screams echoing off the walls of my room.

Realizing what I must look like made me feel so weak and helpless. The humiliation raced through my entire body and seemed to slam into my pink parts.

Becky was again rubbing my bottom but it didn’t feel as good. Her hands seemed to find little landmines of pain all over, making me jump a few times.

“Now, now, baby girl, you only have 10 more to go and we can forget about all this other nonsense. Be brave foe me little one.”

The thought of more spanks across my butt again filled me with both dread and delight. I tried to clench butt but the first slap made that go away. Nine more of them followed in no particular rhythm. When the final one was struck, I just buried my face in the bedspread, my crying out of control.

Becky started rubbing my back and ran her fingers over my head. She turned me toward her and threw her arms around me, holding me close. I put my hands around her waist and sobbed.

Big Sister’s Submission Part 3

(While talking things over with her older sister, Becky gets an idea and starts scheming with a couple of her friends to make it happen.)

After a lengthy recovery time, in which Becky allowed me to sleep in my own bed, she came to collect me. She sat at the downstairs dining table while I was kneeling beside her, still naked.

“With mom and dad returning home sometime this week, we’ve got to find another location for our arrangement,” Becky said. “I don’t want you confined to just your room. That’s not fair to either of us. I wonder, dear girl, if you had any thoughts?”

“I do have some thoughts Mistress but I can’t articulate them just now,” I answered. “I do have a major question though. Since there are just a few months left before I graduate, what happens after that?”

“That depends on you little one. What are your college choices? Are you still in the running for that scholarship? Where do you plan to live?”

“I’ve narrowed my choices to either the University of Texas or Paramount University and yes, I’m a finalist for a scholarship; they’re awarding three of them. If I go to Paramount I can live here, or I could rent one of the school’s apartments, especially if I get the full scholarship.”

“How interesting,” Becky said. “You just gave me a great idea. I’ll explain more when I get home from school tomorrow.”

As a senior, I had the final hour of the day free and usually just went home. Becky had already told me to be in position by the time she got home.

We continued the conversion for about an hour before she requested me to cook and serve dinner. She went upstairs and I went to the kitchen to prepare the meal.

After dinner, with me clearing the table (usually her job), we watched television for a few hours. She allowed me on the couch with her as long as I sat on knees and didn’t make a sound.

She sent me to bed at 8:30 p.m., more than an hour earlier than my normal bedtime. She allowed me to sleep in my bed but I still remained naked. It had been nearly 30 hours since I last wore clothing and I didn’t mind it. What I did mind is that Becky stuck the pacifier in my mouth.

I replayed everything that had happened, beginning with her catching me on the computer and it seemed like an emotional whirlwind, with complete humiliation mixed in with an arousal I could not deny. I fell asleep with the pacifier still in my mouth.

In the morning, after using the bathroom to clean up and prepare for school, Becky allowed me to get dressed. She assigned me one of her white tank tops, one of her bras, one of her panties and one pair of her jeans. She didn’t care about the footwear. She is a size smaller than me, though we used to share clothing all the time.

Today, though, her clothing felt a little too tight. I had to suck up my belly to fit into the tank top, which forced me to push out my breasts a little farther than normal and her jeans squeezed my waist, making it a bit harder to breathe. Her panties kept digging into spots I’d rather not say.

We don’t normally see one another during the school day but she made it a point to run into me a few times that day, once pinching my butt and always making a remark about how “tight” I looked.

Becky sat with her two best friends, Amy and Daniela, at lunch, which ran an hour later than the upper-class lunch. She knew that Amy had a crush on me, so she wanted to invite her home that day to maybe see what might develop. She wanted to play matchmaker.

When I was a junior, I shared a science class with Amy, who was an advanced student and was able to qualify for the junior science course. They had been assigned to each other as lab partners and worked closely on several projects. Despite being older, I had to defer to Amy a lot during their projects. I recognized Amy as the better science student and reluctantly followed her suggestions.

Becky, Dani and Amy sat as far away from others in the cafeteria so that Becky could suggest her plan without being overheard.

“You know Amy, my big sister likes you,” she said. “You really impressed her with her science knowledge. Too bad, you couldn’t be classmates again this year.”

“That’s only because I’m in Advanced Chemistry and she got stuck in remedial Biology,” Amy said. “She needs to pass that course to graduate. And what do you mean by ‘likes me?’ “

“Look, I know this sounds crazy but I think I could hook you two up for a date,” Becky said. “Bobbi is a lot different this year. She’s a lot nicer.”

Amy chocked on a French fry. “What are you talking about? Seniors don’t hang out with sophomores.”

“Like I said, it’s different now. You could go to a movie, to the park, or even a coffee shop. It’s all trendy.”

“Does she know how much I like her?” Amy asked. “Does she know I’m into girls?”

“All I can tell you that she gushed on and on about how good at science you were and how smart you are. So, maybe she knows. Just come home with me today – you too Dani – and let me get you two together just to catch up on stuff. Be yourself. How bad can it be? At least you’ll get to talk to each other again.”

I received a text from Becky telling me she’s bringing a couple of friends over and that I better be nice. I panicked. I mean, I already got out of her clothes and planned to stay naked the rest of the day. Was she warning me to put her clothes on again? Or did she want me to be in position for her? Maybe she wanted to humiliate me? Did she tell them about our new relationship?

They’d be here in just a few minutes. I grabbed my phone and started typing away.
