School - Thursday
Heading out to the car, Niki was almost used to the half-naked walk that Max enforced on her. Her eyes still darted about, seeking out any nearby neighbors, and she was somewhat mollified to only spot Trent watching from next door - albeit a bit discreetly from his porch. After all that he had seen in Niki’s backyard, he was relegated to the safe zone - safe from further embarrassment. As soon as she got in the car, replacing the skirt that was hanging from the rear view mirror with an unworn one, she glanced at her step-brother, who was simply sitting and waiting for her, not even starting the car.
Flushing a little, realizing what was expected even if it was not spoken aloud, she leaned over the seat and opened his pants, her hand and mouth quickly enveloping his already stiff prick. She slid her mouth up and down his shaft for a long minute or so before she heard him start the car.
“So glad you like to fuck dogs, slut. This has got to be the best way to drive you to school!”
Niki flushed. She had not really embraced the fact that she must like fucking dogs so much as it just sort of happened. And once it happened, rather than fight it, she had surrendered to it. Or so she told herself. As she sucked her brother’s cock while he drove, she could feel her matching arousal making her thighs damp. Perhaps she was just a slut, she thought. Who else would get wet from having to service a rude boy like her brother?
“Hold on a second. I let you walk out today wearing your shirt - no punishment after all, but I think I liked yesterday’s trip much more. Let’s see, naked is for when you are being punished - at least for now, so, new rule - you get to wear only one item until you get me off. You can pick. Shirt or bra, but if it’s your bra, you don’t get it back until tomorrow. How’s that for a fun game? Nice huh?
Niki felt heat building inside her at the continued shaming control Max liked to exert. Her hard nipples and wetness between her legs gave mute proof to her mind and body’s enjoyment of his rude games. She took off her shirt, feeling a flush of nervousness as her top half, clad only in her bra, was exposed when she turned to put it in the back. Once again, thrilling tendrils of energy darted through her due to just how outrageous her behavior was. Good girls definitely did not get naked, or half naked, in a car on the way to school!
Obediently returning to her task, Niki inhaled his hard shaft again, feeling his eagerness thrusting up into her mouth. Only a week or so had gone by, and she could barely remember a time when she wasn’t sucking on him. Feeling an answering tingle in her insides, Niki could not really blame him all that much. She obviously enjoyed this. All of this. It was just ... shocking.
She felt him throb and thrust with more energy, and she sensed he was getting close. A low moan escaped his lips as she bobbed up and down his shaft eagerly. When he held her head with one hand and began to shoot inside of her mouth, she struggled to close her mouth and swallow, stopping when he announced: “Hold it, don’t fucking swallow until I tell you!”
Niki felt him shoot off a few more times before he let go of her head and let her slide her mouth off of him. She could feel his stuff coating her mouth, her tongue coated with his cum, and her mind steadfastly not thinking about what was coating everything. She looked at him, a bit like a deer caught in the headlights, and waited for his permission.
“Best get dressed. And don’t swallow until you are inside. I want you to think about me the whole way into school!”
Niki jerked back, looking around and realizing they had once again gotten to school without her quite being aware of it. Remembering his order not to hide just yesterday, she did not duck down even though she was sure everyone could see she was only wearing a bra. She darted her hand back into the back seat, her nearly nude body most assuredly on display, and worked to get her top half covered as quickly as possible, her full mouth making every movement a challenge.
Quickly getting her shirt back in place, she grabbed her skirt and, without any fanfare or attempts to really hide anything, pulled it up her legs and over her hips, collapsing back into her seat with a muffled (mouth full) grunt. She stared at her brother, shocked and turned on, and got out of the car, ignoring the crowd that had gathered nearby. Word was obviously spreading about the show she kept putting on.
“Did you see? I swear she didn’t have a shirt on until they pulled up!” “Yeah ... I saw her bra. Fucking nice!!” “No way ... her bra?” “Probably naked again like yesterday or something. She’s really crazy.” “Yeah, total nympho!”
Cyndi hurried over, smiling, and tried to engage her in conversation, though Niki steadfastly kept her mouth shut, simply shaking her head no. Cyndi stared at her, and then at Max’s car pulling away, and blushed a little.
“Again, huh? God, I can’t believe you!”
She didn’t sound upset, really, more like she was teasing. Which was good, Niki thought as she made a beeline for the girls’ washroom, quickly splashing her face with water and sucking a little bit of the water into her mouth to wash some of the taste away.
“God, he...” she said, turning to explain it to Cyndi, stopping when she realized there were quite a few girls nearby. “Later ... I’d better hurry to Comm.”
“Sure! Lunchtime again?”
Niki nodded before heading off to Mr. Jackson’s class.
Communications class was rather tame today compared to her near-constant teasing the day before. She did have her bra on this time, so she kept her teasing to a minimum, parting her legs teasingly only a few times when she was sure Mr. Jackson was looking. She wasn’t really worked up or anything. It was just kinda fun.
Like the day before, Roach and his buddies found her as soon as class let out, and they bracketed her as they walked towards Art class.
“Hope you are ready for tomorrow! Not that you need to worry about it too much. The way you ride to school, modeling should be easy-peasy! Besides, I know how wet you got yesterday - even if you didn’t let me check! Just imagine a whole hour of everyone staring at every inch of you!” Roach was obviously excited about what he had set up. Niki was not a hundred percent sure about it all, but, like everything else lately, she felt as if she had little choice. The decision had been made, or so it felt.
Arriving at the Art classroom, she stopped at Ms. Dougal’s desk and handed over the permission slip.
“Oh, great! I am so glad that you are interested. It’s going to be quite the exciting time, for sure. That reminds me,” Ms. Dougal said before turning to the class.
“Do not forget your permission slips. No slip, no class!” A number of students hurried over and handed over their slips, while the rest ignored the chaos.
As class got underway, Niki nervously kept an eye on Roach, though he seemed to be ignoring her. For all his talk of being in charge and being able to do whatever he wanted (at least in a few of their classes), today was rather anticlimactic. At first.
“Yesterday was such a nice show. Why don’t you undo a couple of buttons again today? You are quite lovely. Besides, tomorrow you are going to be completely naked; it’s only fair we get a preview today.”
Niki glanced up at Ms. Dougal, shifting a little in her seat.
“I told you, we have her under control. You could strip and walk around the room, and she’d not say a peep!”
Niki shook her head, though the image of her walking naked amongst the class was enough to get her juices flowing again - and naughty, impure, and definitely improper thoughts began to run through her mind.
“We have this place wired, and your brother was quite clear that looking was just fine. So why don’t you sit down and undo a couple of buttons while you are at it? Roach was confident, his voice steady, his eyes never leaving hers, not even to get his buddy’s approval - this was all about her and him.
It was almost like she wasn’t in control sometimes. Whether it was Max, at home, or Cyndi at lunch, or now, with Roach in Art class, all someone had to do was suggest, or dare, or tease her into doing something. And she did. Her fingers quickly undid the top two buttons of her shirt, and she felt that familiar daring thrill shoot through her.
“Good girl!”
Roach echoing everyone’s words seemed to make her flush with arousal even more. And when she caught him staring at the parted opening at the neck of her blouse, she reached up and undid another button without even being asked.
“Hmm, shit! You have a bra on again. I thought Max was making you go without?”
