Satisfaction brought it back

David took a moment to respond, still caught in the scene before. By the time he eventually pulled himself from it, she was gone, her bedroom door an impassable barrier. He took up the stairs and knocked, frowning, thinking about what just happened. He shook his head. It would be easy enough to just ask. He knocked again, calling out, and though he heard noise, movement, scurrying on the other side, there was no response.

"Hey sis," He began, the idea suddenly coming to him, "Whenever you hear me speak to you, or ask you a question, you have to respond honestly." He paused, waiting for a response. He knocked again. "Hey sis? What's up?" The noise stopped suddenly. Silence permeating from the room like a sickly aura.

"It's just, you know." She paused here, the sound of movement picking up again, and David could only wait, as she considered her words. "I know that when we're alone, and not going to be disturbed, I can only wear my underwear, and that's embarrassing enough, but to also forget a bra and show you my bare tits is even worse." She paused. He paused. "Don't tell mom I swore?" David laughed.

"Don't worry sis, It's fine. This may sound a little creepy coming from your brother, but I mean, with you already like this, I figure it won't make it any worse, so... For what it's worth, you have nice breasts." Once again the sounds stopped. He could almost hear the frown in her voice.

"If I hadn't shown them to you myself by forgetting a bra, that would have been really creepy." There was a gap in her speech, but even the first part alone left his heart clenching. "But still, I guess I did show them to you, so I mean. It's not your fault. So thanks. I guess we're not so good at the cheering up part as siblings huh?" She laughed, the sound breaking the tension, as her bedroom door opened just a crack, a slither of her face showing, the rest of her hidden behind the door. "Still, I don't really want my younger brother ogling me in my underwear, so I'm just going to stay in here till mom's about. Sorry." Despite it all, he could hear in her voice that she was actually sad to be purposefully avoiding him, and instantly, with little thought he came up with a new condition.

"Hey sis, Every time you purposefully avoid me, you have to slap yourself on the ass." He quickly thought about the mental evaluation of exposing yourself in underwear to your brother and slapping yourself on the ass, quickly changing his mind. "Wait no, on your pussy. Hard." He paused, smiling, sure that this would work. No-one wanted to go through that, man or woman. He smile vanished when he heard it. A cry echoed from the room, filled with pain, and subtle undertones. He paused, his eyes widening as he realised what he had just done. He reached for the door, before pausing, hands just off the handle, as he called through to Amelia. "Hey Ame, you okay? What happened?" He merely heard a moan through gritted teeth in response, having to repeat himself before she could register that he was even talking.

"It's okay bro. I just realised I was avoiding you. *Ow* that hurts. guess I'm not doing *that* again. Just give me a second to stick a bra on, you kinda interrupted me when you knocked." Another dull thwack, and another cry through gritted teeth, he could hear her letting him in, even as he heard her still moving across the room. "Actually it's fine. You can come in."

"You sure sis? Sounds like you're still not dressed." He pitched his voice slightly, wanting her to hear, but trying not to wake up their mother.

"Ow, yes I'm sure. Owowow. It's fine. You can come in. I'm not avoiding you. Feel free." There was something about what she just said that should have stood out to him, he was sure of that much, but he couldn't put his finger on what. He shook his head. Things were moving so fast he couldn't properly keep up, but when he had a moment later on, he'd think about it. For now, he cast it aside. He opened the door. He had been right in that she was still looking for a bra, and in the short instant he thought about her wording, that hadn't changed. She did however, have her back to him, and the muscles, just like the front, were sleek and visible, yet not prominent, having signs of development through use in a practical form, rather than simply putting on muscle at the gym for the sake of bulking up. Her black hair ran low down her back, spreading off the sides below her armpits where they overflowed, pulled back by their own weight. Her panties, black as they were, squatting as she was, were stretched across her backside, the slightly loose fit from earlier having disappeared with the different posture. He watched as she stood, her hands reaching behind her back, clasping the pins of a dark blue bra, likely the first one she could find. A quick fumble, and some twisting of her back and arms, and she turned around, showing of her front in its almost naked glory. The lower half he had seen before, but the bra, where her breasts had hung, supported by their own flesh and muscle, they were now held up by cloth and wire, presented before her like a prize for a grand champion. He coughed, trying to clear his head, even as he avoided staring at her tits. A difficult task to be sure, but he couldn't simply make a condition that she had to accept it. It just wouldn't work.
