Chapter 18: Cyndi returns for another visit

Tuesday after school

Opening the door, Niki moved to lift the seat for her friend to get in back, like last time, but Max shook his head. Unperturbed, if a bit uncertain, Niki paused, slipping her skirt off before she crawled into the car, scooting over to make room for Cyndi to sit next to her, not waiting to reach up and hang up her skirt.

Cyndi was well aware of how Max had forced her friend to ride home, smiling as she watched Niki place her skirt on the rearview mirror. What was new, and a bit more shocking, was when Niki removed her tube top as well, tossing it into the backseat, and turnied to wave at the watching boys. Obviously, this was a new ‘rule’ put in place since Cyndi’s last trip with them.

Max had not said a word, simply sat there, strumming his fingers on the steering wheel, waiting for his slut of a sister to do as she was told, ready to move if anyone honked, but thankfully no one did. Glancing down at his lap, he waited, sure his sister knew the routine by now.

Niki looked at him and then back at her friend. He really was going to do this to her again. Moving over to put her face in his lap, she exposed her backside to her friend as she opened his pants, pulling out his cock, knowing that he would not pull away until the head of it was in her mouth.

Max put one hand onto the back of Niki’s head and pushed her down onto his cock, looking over at Cyndi and smiling “This is just the routine for my sis, I am sure you understand. Maybe next time you can take her place if you want,” he said with a laugh before pulling away, one hand still on the back of Niki’s head as he drove. “So Cyndi, how was your day at school? Anything fun or interesting happen?” he asked with a smile when he looked over at her when they stopped at a light.

Cyndi had watched, entranced, as her friend seemed to eagerly suck on her brother’s cock! She knew that Max had ‘caught’ her, and leveraged her into embracing her desires, but it was still a bit unnerving to see how quickly Niki got naked and filled with a male appendage. Her own brother, too! Well. Step-brother. But still.

She shared the mundane details about her boring day distractedly as she watched her friend, Niki’s bare bottom pressing back against her hips - the two were quite close in the front seat. Cyndi kept watching, unable to keep from looking at the stretched, exposed backside of her friend, who seemed okay with being completely naked and sucking on a cock in the front seat of a car, driving down the road, in broad daylight. It was just too crazy. “I heard that Roach’s girlfriend was teasing her during PE, but I forgot to ask her about it over lunch -- she was kinda busy.”

“Yes, well, she had mentioned Roach’s new routine for her yesterday, I guess it cut into her lunchtime you guys share?” Max smirked, slipping his fingers inside of Niki’s slick lips, boldly fingering her right in front of her friend. “Keep me hard but don’t make me cum today, sis,” he ordered as he pushed down on her head.

As they pulled up to the house, Max pulled Niki’s head up, giving her a soft peck on the forehead before patting her head. “Good girl” he added before looking back at Cyndi “Would you mind carrying in Niki’s skirt and shirt, I don’t want her putting them back on again today, she tends to forget to take them off again once we get back in the house so I am only allowing her to wear them at school and no other time,” he said with a chuckle as he handed her the skirt before getting out of the car and opening the door for Cyndi and Niki. He didn’t waste too much time unlocking the door, sparing Niki any extended embarrassment; the walk from the car was enough to make his point.

Niki had said little, as she carefully kept him hard the whole way home. As they arrived at her house, she blushed at hearing Max tell Cyndi to bring in her clothes, sure he was insisting on continuing to embarrass her, even in front of the neighbors. Still, she hurried inside, hoping that no one noticed, glad when the door closed behind them, Cyndi putting Niki’s discarded items on the small shelf.

Once inside, Max looked over at Cyndi.

Cyndi, for her part, was amused, watching Niki’s bare backside hurry into the house. She knew what was likely waiting for her friend, and though it was scary, she wanted to see everything. As she set her friend’s clothing down, she heard Max speak up.

“Now this is only a firm rule for Niki, but as a guest in my home, I would ask that you abide by it as well and strip down while inside. It’s only fair, right? I mean, forcing only Niki to be naked is not being a very nice friend, don’t you think?” he said with a chuckle as he leaned against the wall and smiled at her. “And I couldn’t help but feel that you felt a little jealous of Niki last time you were here, am I wrong?”

tell her to join Niki in her naked state, and she quailed, scared for just a moment.

Looking at Niki, who simply shrugged, as if it was up to her, she looked up, appealing to Max, wondering if she truly had to do as he asked. Thinking about his words, she allowed his sentiments to ‘convince’ her, secretly wanting some reason to feel some of the thrill that she imagined her friend was feeling.

“I can’t, I mean. Ummm,” she said, temporizing. Her inner turmoil was roiling her emotions as she wavered between accepting his suggestion (and all that it likely entailed) and refusing to follow Niki down that rabbit hole so quickly. Though if she were truly honest with herself, she was not sure how long she might really protest. She flushed, remembering just how aroused she had gotten last time - and how wet she had been and how hard she had cum as soon as she had gotten home.

“O ... K...” she said, slowly, uncertain, as she kicked off her shoes and reached for her blouse. As she began to unbutton it, her pale blue bra began to peek through, and she watched as both of the siblings seemed to watch her every move.
