Asim woke up the next morning, with a raging hard-on, only this time he knew what it was for. Last night had been one heck of a night for him, which had led him to furiously jerk off thinking about his own sister. His sister who had deliberately shown him more than she should have.
In the next room, Sarah's awakening was no different. Completely dehydrated, panties drenched. She had been very horny lately, and the most important, her horniness was triggered by exposing to her own brother. She was so fucking turned out by this game that she was playing, and wasn't in any state of denial either. Getting off by herself wasn't working for her anymore, she needed some real action, she wanted to be fucked real good. She immediately called up her boyfriend, she wasn't asking for a romantic date, more like a booty call, luckily her boyfriend had half day at work today. They fixed the specifics and Sarah were excited about meeting her boyfriend in a few hours.
Freshened up, as she was about to leave her room, she heard the TV sounds from downstairs, her brother was home again, not that she minded. Quite the opposite really. She quickly checked her attire in the mirror, and applied some perfume, all this while confused by her sudden inclination of going an extra mile to look and smell nicer to her brother. Deciding to change her attire, she stood naked in front of the mirror, she put on a red bra [red was her favorite color in undergarments] and wore a white t-shirt which had a thin fabric, meaning her bra would be proudly visible. She picked out a pair of shorts that snuggle her tight ass but decided to up the ante even more. She pulled out her red panties instead - not thongs though. Wearing that, she stepped out of the room.
She was feeling very nervous. Going around in her panties was definitely something new, more for the fact that her t-shirt wasn't a long one and came only to her waist. The panties wouldn't be considered slutty, but they were after all panties so a good amount of her ass was on display. Either way, she was ready to do this. When Sarah entered the lounge, Asim saw her at first, then looked again, this time a little longer. Sarah walked casually as if nothing was different about this morning.
While the siblings were having their breakfast, Asim was looking at his sister a lot, and he was doing so very openly. Sarah, too, was looking at her younger brother sitting with her, fully aware that she was being scanned, particularly at her ass, and this was turning her on.
She stood up after finishing her breakfast and did additional strides around him, so he gets a proper view. She was going wild with this whole thing. Asim got up as well and as Sarah went to do the dishes, he simply stood behind her at a distance and enjoyed the show. He then came behind her to put a plate on the counter, she could feel the heat radiating from his body. Asim was also getting more confident, he leaned next to his sister's neck, and said "You smell amazing sis"
"Why, thank you! Not that it's an appropriate compliment that a brother would give his elder sister" from her tone, it was evident that she wasn't complaining, as she smiled and winked at her brother.
"I believe appropriateness is out of the window already" he responded, smiling back. They were flirting with each other openly.
"What? I'm just being free. I don't know how to say this, but when I'm home alone, I like to be comfortable. These mornings used to be 'me time' till you stopped going to work!" again, a lovely smile as she said that, the statement was open-ended and she was expecting Asim to follow it up with a question.
"What do you mean by me time?" knowing an answer already, but he wanted her to say it.
Sarah wrestled with the response but decided to go ahead. "Well, you know... Roaming around the house in undies or... nude" hesitating at the last word.
Even though Asim knew what his sister's going to say, he was delighted to hear the words.
"So, who's stopping you now?" winking at his sister.
"Let's not carried away bro. One thing at a time" she winked, smiled, and she was walking past him, touched his arm lovingly.
Asim surprised both himself and his sister by his next move. As he turned her head to see his sister's panty-clad ass walking by, he spanked at her right ass cheek. Sarah jumped in reaction, clearly not expecting that, she turned to look at him with what could be best described as a confused expression, she wasn't sure how she felt about this sudden gesture, but surely she wasn't going to tell him off. Sarah then surprised herself by simply giving him a naughty smile, and kept walking, her hips moving seductively for her brother's hungry eyes.
Asim grew in confidence due to the lack of disapproval of her sister for this bold move and followed his sister to join her on the couch. The siblings talked about normal things, with occasional glances at one another. Sitting much closer than they normally would. But Sarah wanted more material to get herself more worked up.
"If I wasn't home, would you be walking around naked too?" she asked her brother, inquisitive yet seemingly innocent.
"Not sure about being naked, but without a shirt for sure. I usually don't wear them in my room, if you haven't noticed" reminding her of the times she had seen him in his room, under the covers, his shoulders visible. All that before their recent adventures though.
"Well that's like me not wearing pants, you can take your shirt off if you want... Would make me feel a little less conscious," she said with a soft voice.
He didn't need to be asked again. Just like that, he pulled off his shirt and threw it away. Sarah took her time in checking out her brother's bare chest. Asim was fit, neither very muscular, nor very boney. She liked that actually. She was looking at his bare chest as if it's completely normal to do that.
"Do you mind?" he asked as he moved his hand to her right leg, around the knees. Just adding an additional layer of closeness as they sat together. By the time Sarah signaled no, her brother's hand was already there.
Sarah, without asking for permission, moved her hand towards his chest, using her nails to explore his body. Applying a little more pressure, she was trying to push him towards his side, making him lie down on the couch. Asim quickly figured out what she was going for, and lied down. He then sort of pulled his sister towards him, and now Sarah was literally lying on top of her brother.
As Sarah lay her head on her brother's bare chest, she knew this was going much further than she had ever thought. But she was in no mood of putting an end to this. The scent of her sex was now evident in the air, and as she was on top of her brother, she realized she's not the only one who's turned on.
Asim brought his hands behind her now, pulling her closer to him, Sarah's breasts pressing into his chest, he could swear he felt her hard nipples through the two pieces of clothing on his sister's upper body. Soon he smoothly made his way towards her bottom, Sarah only pressed more into his chest, as her younger brother's hand casually explored her bare ass cheeks, the area that was not covered by her panties.
"This feels nice," he said, first one to acknowledge that something was going on here. His elder sister simply nodded at that but her breathing was much faster now.
