The introduction to the first chapter explains that this story may not interest readers who don't like to read all the thoughts of the girl who is the main character. Just a warning. I still hope you enjoy it. It has to get more interesting with her all naked.

The next morning, I was a little apprehensive about really joining my brother Pete in the bathroom with nothing on. I had, however, warned him that I would; I couldn't chicken out now. Would he have taken my suggestion not to wear his shorts? At the bathroom door, I murmured:
"Don't look," and tried to appear nonchalance as I lowered the ring on the toilet and sat down, then adding softly: "Unless you want to."
My nipples sure didn't look nonchalant. I looked straight ahead at the shower. Had I really imagined he would also be naked? He wasn't. Out of the corner of my eye, I saw his head move, then he murmured:
"I wasn't sure you really would."
"I wasn't either, but I had said so, so why not, and since you have already seen me?"
"Hmm? I guess so."
I wiped a forearm over my erect nipples. It helped, until I started to wonder what to say. Could I ask if he would have left his shorts off, if he had thought that I would be naked? Oh, and my other question from the morning before: if she had done anything else with him? I didn't try to make my nipples relax again, knowing they would still be stiff, now that I was thinking about that, about what he had told me he did with her. My first question:
"And if you had been sure I would?"
"Hmm!? ... If I would have too?"
"Yeah, I guess that's what I was thinking."
"You wanted me to?"
"Well, like I said, it seems kind of silly putting something on, if we both sleep n... - that way."
"Hmm? ... You do want me to."
It wasn't a question; I didn't have to answer. He must have recognized that I want to see his cock. Had he, was he remembering what they had told me about it? He was beginning to wash the soap off his face; I had to say something:
"I wouldn't mind. Just seems kind of fair."
"'Kind of fair'," he murmured with his face still over the washbasin.
"Um-hmm," I murmured, hoping it encouraged him to think that was all I was suggesting.
He raised his head and looked at me in the mirror. Could he see my breasts in it, see that my nipples had popped out again? Had he ever seen them when they weren't?
"I don't know," he murmured and grabbed his towel, drying his face before he turned to me. Wasn't his cock pressing a little on the left leg of his boxer shorts? Whatever he was thinking, it knew that I wanted to see it. Of course, he must know it was like that, maybe just not that I could see it. I had long since wiped. I flushed and stood up. I was blushing a little. This wasn't like with my friend, both of us naked. He lowered his towel, that had also been hiding his eyes. They opened wider. If my nipples could be even stiffer -- it felt like it -- they were. In a pure reflex, my arm wiped over them again. It looked like he tried to repress a grin, then murmured:
"At least, you're blushing, and that didn't work."
It hadn't, they were still stiff, but then I could nod with wry smile, shrugging in response. Of course, I had wanted him to look, even though it had made me blush. He stared at me -- up and down -- and then murmured: "I'd better get out of here."
He did. "Had to get out," because his cock had been pressing even more against his shorts? Why hadn't I looked? I took my shower, recalling our conversation. At least, he hadn't said "no," and hadn't said anything about my being his sister; and wasn't "being fair" part of his sports ethics? Well, that was really a contrived excuse. But he hadn't said "no." Didn't guys like to have girls see them naked, like I liked being seen naked? Not just by guys, well only one, I also liked being naked with girls in the school showers after sports. Everyone must like to be naked.
While I was drying myself, the bathroom door open, he left his room and glanced back at me. I grinned, maybe after he had turned away, but he had looked, and seen that I had seen that he had. He couldn't be too bothered by admitting that he liked to see me naked.
At breakfast, although we again reverted to our accustomed roles with our parents, I thought he gave me a veiled smirk. If it was -- were, better English -- he had still been thinking about it -- also thinking about letting me see him naked? If he did, what was I going to say?!
That day we both had different things to do. Luckily, because my thoughts kept returning to our morning conversations and wondering whether he would have his shorts on the next morning. The panties I took in bed with me that night were still a little moist. We hadn't shared the bathroom in the evening. Was that good or bad, hopeful or discouraging, I wondered with my fingers in my pussy and rubbing my clitoris, then remembering that I could ask him if he did that too, thinking about Barbs.
The next morning -- the next morning! Through the door, I saw that he was naked! Slender hips, nice ass, at least from my minimal experience.
"Don't look," I warned him again, and went to the toilet. He had already turned down the ring for me.
"Don't you, either," he replied, adding: "just to be fair," but chuckling softly. Then he remarked: "But you're going to, so better now, before I do."
In the mirror, I saw him close his eyes tightly, his face covered with shaving cream, and he turned.
Oooh! His cock! I understood his remark. I had only seen my friend's when it was aroused and then all small, when we were getting dressed. Pete's was somewhere in between: it was still hanging down, but bigger than my friend's had been, when we were getting dressed. And it looked different, a fold of skin covering its head. Not quite; the tip of it was peeking out, and while I looked, more of it was visible. He still had his eyes shut. What would happen if -- when -- he opened them and saw me with my aroused nipples? I wanted to know - of course!
"This is being embarrassing," he murmured, his eyes still clenched shut.
"Better not look then; shave."
With a grin on his soapy face, he nodded. My eyes dropped down and saw that more of the head of his cock was visible, before he turned back to shave. With open eyes, he looked at me in the mirror and murmured:
"It wasn't supposed to be like that."
"Thanks. That's alright; I didn't mind. I can't keep them from popping out when you look, even when I think that you will."
"Hmm? Hm-hmm! Something like that."
We both chuckled, and he shaved. I decided to save all my questions for later, and just sat there, not thinking about them, and my nipples relaxed. When he had finished shaving and washed his face, he turned, letting me see it again, now smaller. I liked that it was, that our being naked together didn't have to be arousing, and my nipples weren't either, until he looked at them before drying his face. Had he covered his eyes with his towel again to let me look at it some more? He could have used one end of his towel and let the other end hang down and hide it. He hadn't; he wanted to let me to see it. At least, it hadn't occurred to him that he could have dried his face that way.
Maybe he knew that he was letting me see it, wanting me too, since the head of his cock peeked out a little more. When he lowered his towel, but not covering it, he snorted with a wry smile and murmured:
"Stop staring! You're not supposed to see it that way."
I grinned with a nod, my eyes jumping back and forth from his face to his cock. Even though its head was wanting to peek out more, he only shrugged slightly, and murmured:
"Well, I guess you do."
I nodded. The roll of skin was slipping further up. Oh, I wanted to watch it let me see the whole head of his cock, which was beginning to be bigger, but I managed to reply:
"You had better go."
He gave me a sweet smile and turned to hang up his towel. Before he left the bathroom, I saw that his cock was even larger, not just hanging. Pleased with my discretion, I took my shower. I had seen it, he had let me see it. We were going to be naked with each other again. I could save my questions until we were both more comfortable -- less aroused -- at seeing each other. But then, if I dared ask him if Barbs did anything else with him, or if he rubbed his cock? Now I had a much better impression of how he could do that, how Barbs could do it, but she probably didn't any more, now that they really did it. But that would be fun, doing that!
The next morning we both were naked again and much more relaxed about it. My nipples only popped out when he stared at them, but then smiling and watching me look at his cock. He must have felt that it moved a little, but he didn't seem to mind, just smiling with a chuckle. He was enjoying it too! Even if I couldn't ask my questions, this was being delightful!
The next morning was even more relaxed, my nipples and his cock. I didn't want to upset that and kept my questions to myself, my nipples not even popping out when I recalled what the questions were about. Funny, how the roll of skin completely covered the head of his cock, almost a little tassel closed around it. I hadn't seen it like that before, but when I was taking my shower, it occurred to me how much loose skin there must be to rub up and down on his cock. I wanted to do that.
