Rosalyn embraces him first

"Josh!" his sister called out, breaking his train of thought and bringing him back to the matter at hand. Sarah quickly dodged out of the way as Rosalyn rushed him, nearly jumping in his arms as she embraced him in a warm hug.

"Hey Rose" he chuckled, pulling her in. The siblings stayed locked for a handful of seconds, enjoying each other's long lost company, before Rosalyn looked up at her brother, smiling brightly. "How was the trip?"

"Good!" she said as they disconnected, "Wasn't as bad as I thought it would be. It helped that I caught the early bus."

He nodded along as he entered the living room proper, Rosalyn trailing behind him. Sarah, letting the siblings reconnect, had disappeared deeper into the household.

"Unfortunately, I finished my book early in the trip" she continued, stopping next to the luggage she'd discarded not long after arriving herself. "But, I got lucky. I sat next to very kind, older woman who was coincidentally getting off at the same stop as I was. She didn't have any entertainment either so we chatted briefly before deciding it might be best to just make out. Ahh, kind of like Sarah and I just now, actually."

Josh froze the moment he heard her say 'make out'. "Sorry, what?" he asked, turning around.

If his sister heard him however, she ignored the question. "Anyway, I'm gonna go put my luggage away. I know I'm only here for a few days, but a girl's gotta have her wardrobe, you know?"

Before Josh could ask anything else, Rosalyn grabbed the large suitcase, lifting it with a deep groan of effort. It swung broadly as she made for the hallway, intent on disappearing towards her temporary room. Josh watched her go, stunned at the conversations he'd just had.

Reaching for his pocket, he took out his phone. He stared at it with wide eyes, the small electrical device suddenly having a weight it had never had before. If he had truly changed the rules of the world... If the app truly worked as he now suspected...

It was impossible. There's no way a small iPhone app could literally change the laws of the world and the fabric of reality itself. The only logical explanation was that Sarah and Rosalyn knew about his wishes in advance and planned to fuck with him. He must have accidentally sent that change to Sarah and she ran with it.

But when he checked their messages, there wasn't anything of the sort. Just her telling him that his sister had arrived.

That left only one option.

The app was real.

The world seemed to slow as he moved his thumb, reopening the app with two quick motions. Just like before, an endless list of rules and actualities that made up the world around him appeared before his eyes. A list that, if he edited, would **** reality itself to change and conform to what he'd written.

The power he had at his disposal.

He had to test it, understand how it worked, and how far-reaching was its abilities. Quickly, he scrolled through the endless array of text, reading each rule as they passed on his screen, hoping one that would spark inspiration. He soon found one that detailed how most people enjoyed changing into loose, more comfortable outfits once home, and decided it was the perfect rule to add upon.

• A girl's idea of a comfy, at home outfit consists solely of thigh high socks, panties, and a loose, open hanging cardigan. Depending on who's over, they sometimes opt to wear an oversized t-shirt, although the alternative is much more preferred.

Just like before, the new rule entered without mishap, almost causing him to doubt himself once more. Instead, he steeled his resolved and made his way further into the abode, intent on finding on the women.

As he passed by his room, Sarah's head peaked out and hushed him inside, closing the door behind him as she dragged him. What he saw took his breath away.

The app undoubtedly worked. Before, Sarah had always dressed modestly around the house, his girlfriend insisting that it was possible to be comfy without showing a bunch of skin. Now, she instead wore exactly what he'd described in his change - long white cotton thigh highs that covered her toes to her mid thighs, plain pink panties sitting a few inches above them, and a loose, rose colored cardigan that left her mid-rift completed exposed and opened her tits to the world. It was something she'd never wear, yet here she was, wearing just that. It was all the proof he needed.

It was only when she smacked his arm and told him to stop staring that he realized she'd asking him a question. "Sorry, what?" he asked dumbly, finally looking up from her tits to her face.

His girlfriend rolled her eyes. "I said, do you think Rosalyn would be more comfortable if I wore a t-shirt? She seemed pretty quiet earlier, and I'm hoping it wasn't because of the boobs."

Josh blinked, utterly baffled that he was currently having this conversation. "Um... no, I don't think so?" He didn't know; would his sister be comfortable with his girlfriend walking around nearly topless? Surely, considering Rosalyn had come all this way for a talk on feminism. "She's pretty open minded."

Sarah grinned something sinister. "Good!" Without another word, she reached over and kissed him. Instinctively, his hand snaked their way around her waist, grabbing naked flesh beneath her open cardigan. The girl, holding the hem of his shirt, pulled him to her and **** him to tumble onto the bed, lips still locked as he landed on top of her. Sprawled beneath him, hair a disheveled mess and cardigan now fully open to expose her tits, Sarah giggled. From the deep haze that clouded her eyes, Josh could tell that his girlfriend was aroused.

"Making out with Rosalyn was rather arousing" she stated while nibbling his ear. "I saw the size of her suitcase. Think we have time for a quick fuck before she unpacks?"
