Big Sister’s Submission Part 7

(Becky sets Bobbi’s punishment; Bobbi goes on her second date with Amy)

My dress code outside of my room was a T-shirt and panties: no bra, no shoes, no socks. I’d usually wear shorts and socks at home, so even the slight difference was effective in making me feel like a little kid.

I had spent the last hour thinking about what my punishment should be after forgetting to call her “Mistress.” It was a darned if I do, darned if I don’t kind of thing. If I didn’t come up with a good one, I’d probably get it even worse.

When I sat down at the dinner table, Becky didn’t waste time asking me what I had decided regarding my punishment. I looked around to see if our parents were around. My mom was still in the kitchen and dad was watching television in the living room.

“Can we wait until after dinner,” I asked in a loud whisper. “Please Mistress.”

“Nope. You better hurry if you don’t want our parents to hear. I’ll make you announce it during dinner.”

“Fine, so I think 10 swats on my naked butt over your knee, followed by corner time … Mistress.”

Becky looked as though she was considering it and I was getting antsy. She deliberately took her time, taking delight in my uneasiness. Just as our mom announced dinner, Becky said “Triple it.”

I saw my mom come out of the kitchen with the main dish, so I hurriedly agreed. Becky clapped in her hands, a broad smile on her face. I wanted to hide my blushing face.

Our father went into the kitchen and brought out our side dishes. Our drinks had already been poured.

Our parents told us about their trip and asked us how school was going. It turned out to be a regular evening, although every time I glanced at Becky, she was smiling at me. I felt like my upper body turned into a furnace and getting hotter.

After dinner, Becky and I cleared the table, did the dishes and cleaned up in the kitchen. Our parents remained at the table, each with a cup of coffee.

Becky walked with me up the stairs and into my room. I took off my T-shirt and panties and stood there, naked, waiting for further instructions.

“I’m going to do you a favor,” Becky said. “I’m going to defer the 30 whacks until tomorrow. I’ll give you the choice between an hour of corner time in front of your computer or a half-hour in the living room, with the drapes open.”

“I’ll take the computer for an hour Mistress.”

“Good choice, little one. You may begin while I go to my room and relax. You’ll be so much fun to watch.”

You just don’t understand how humiliating it is, to stand in the middle of your own room, naked and with my hands behind my head, facing my computer while my younger sister sits comfortably in her own room, watching me.

Embarrassment washed over my whole body as I realized how small and vulnerable I felt just standing there alone but knowing I was being watched. Gosh, she could be recording this or even live streaming it. I shuddered at the thought. The deferment of my spanking didn’t really help either because I was going to spend the whole day thinking about it.

I successfully held my position for an hour, even as I felt the rush of embarrassment pass through me. There was also a rush of excitement simultaneously that affected another part of my body.

At school the next day, my thoughts bounced between the spanking and my “date” with Amy. I liked Amy but that was it. I didn’t want to have to say yes to everything but when you put yourself in a submissive relationship, what I wanted didn’t matter. I had to remember that however I am pushed, I actually want the feeling of obeying someone. I never thought it would be my 15-year-old sister. I had hoped for someone in which I could build a relationship.

I decided it was practice for when I went off to college in the fall and really explored all the possibilities. It hadn’t dawn on me yet that Amy had also assumed a dominant role, even if she wasn’t aware of it.

I passed Amy in the hallways just before my final class. She raised her hand over her hand and waved. I waved back, though not as enthusiastically. She still had two classes left and I would have to wait in the library, where I usually wouldn’t want to spend time.

After my final class, I spent the next 50 or so minutes in the library -- on one of the computers. There were several sites blocked, including most social media platforms. So, I searched make-up ideas for my age (17) and was encouraged to avoid heavy foundations that would clog my pores. My mom reminds me all the time, even on Halloween.  When you can’t get on Tik Tok, Pinterest or Instagram, you don’t get many cool ideas.

The final bell rang and Amy appeared less than a minute later. She tossed her backpack into the cubicle and told me she’d be right back. I got a whiff of her perfume as she walked into the stacks. The pleasant aroma stayed with me for a few minutes. I stopped using the computer and just sat there enjoying the scent.

Ten minutes later, Amy returned with a stack of papers she copied off the internet. She told me about the research she’s doing on climate change and how it will affect our future. I figure things will just work out.

As we left the library, Amy asked my opinion. I told her I thought it sucks that previous generations have negatively affected the world we’re about to inherit.

“What are you going to do about it?” she asked.

“What do you mean, like recycling?”

“You’ve got to be proactive, set goals to help reduce carbon emissions,” said Amy. “Recycling is good but there are many other things you can do. Promise me you’ll look into ways you can reduce your own trash and maybe stop using products that are sold in plastic containers.”

I knew she was interested in saving the Earth and I was beginning to understand just how serious she is about it. So, I promised to cut down on my trash and reduce my use of plastic materials.

Amy started smiling and said we should walk out toward the athletic facilities where the girls’ soccer team was practicing. As we got closer, she slid her right hand into my left hand and locked fingers. I was shocked but did not pull away. I still had to be nice to her. I looked at her and our eyes met. She looked radiant and that caused me to smile. And there was that sweet scent of her perfume.

Amy led me around the practice field, from where we could watch the team preforming drills. I knew several of the team’s members and had classes with at least half of them. I had the feeling she was showing me off, like we were in a committed relationship. I felt embarrassed and knew I would be getting some questions the next day.

As we walked toward a park which backed up against our school, she asked me my position on LBTQ+ rights. I followed the “Love is Love” motto and felt they should be given every opportunity as anyone else. I didn’t want to talk in depth even as Amy peppered me with questions. I just kept agreeing with her.

We had reached the park and she led me to a group of large trees where we could avoid being watched. She let go of my hand and angled me so that I was leaning against the truck. She stepped up until her face was within inches of mine. Her eyes shone brightly and I was mesmerized by them.

“Can I kiss you, Bobbi?”

 My face boiled with heat and a sensation I can only describe as both scary and wonder ran through me. I couldn’t breathe for a few seconds and I couldn’t open my mouth. I looked at my feet, then back at her and nodded my head yes.
