The new girl

teasing her, but she never complained; all she ever had to say to me was words (at first; later, it was just noises) of appreciation and encouragement.

I must have spent nearly half an hour that way, slowly moving Charlene's arousal higher and higher before I recognized the signals that she was getting damn close to having another orgasm… one that would put the previous one to shame, if I was reading the signs correctly. I'll confess to being more than a little concerned about what might happen with her, but she'd not only said that that was what she wanted, but she'd told me that she'd let me know if she thought it was going to be too much; despite my reservations, I kept my word to do the best I could for her. Knowing just how excited she was, I deliberately slowed my actions as I moved her to the brink of her release — then let her slide back again, prompting her to release a deep, frustrated moan as she tried to press herself up against me. I didn't let her find the relief she sought, and when I heard her soft whimper, went back to stimulating her again. The second time, I slowed my actions even more, and managed to hold her at the very brink for a couple of seconds before nipping at her clitoris with my lips pushed her over the edge.

She did scream with the start of her orgasm, but it was cut off by the force of the first incredible spasm that nearly folded her in half. She didn't have time to even begin to straighten out before a second wave of pleasure overwhelmed her. She was about halfway straightened out again when a third spasm froze her in place with a deep groan; from that point on, the rest of her climax tapered off fairly quickly… due mostly, I think, to simple exhaustion of her body. She was stretched out, shivering while intermittent shudders and spasms ran through her body when I again got myself laying next to her and into my arms. As I was holding her, Eva reminded me of her presence by saying 'Yeah, you hold her like that, and I'll go get a damp cloth…', then clambering off her bed and heading out the door.

She reappeared a few moments later, handed me a washcloth, and said 'Start wiping her face while I get something for you two to drink' and disappeared again.

Doing as I was told, I gently wiped Charlene's face until Sis got back with cold sodas for all of us. She set them on her night stand, then took the washcloth from me and said 'You just hold her now, and I'll take care of the rest.'

It couldn't have taken much more than another minute before I saw Charlene's eyelids start to flutter; a few seconds more, and they opened — though it was pretty obvious that Charlene really wasn't seeing much of anything just yet. Sis wiped her face again, and that seemed to help; when Eva began to carefully wipe up the collection of fluids from between Charlene's thighs, Charlene tried to protest but couldn't quite make it happen.

Once Charlene was cleaned up, Sis left us again to do something with the washcloth; while she was gone, I went ahead and opened up a soda and managed to get Charlene propped up enough that she was able to take a couple of sips from it. Just as Sis was coming back into her room, Charlene said 'That was way more than I thought it'd be. I mean, I knew you were teasing me, and it kept feeling better and better; and I could feel it building inside me, and I knew it was going to be a big one — but I really didn't expect anything like that.'

After she was seated on the bed with us, Sis looked closely at Charlene and asked 'You're okay?

Really?'

'I'm fine', Charlene answered. 'I think the only reason it left me feeling like this is because of how big the other one was. Besides, I knew it was going to be the biggest ever, and I didn't tell Billy to stop or anything even though I could have. I don't think I want to go through anything like that again any time soon; but, honestly, I'm not sorry it happened.'

Following that, she turned to look at me and said 'More than anything, I'm glad it happened. I've, you know, given myself orgasms before, but I've never had anything like what happened tonight because Billy did things that I just can't do. I've always been afraid and worried about what it would be like if I was ever with a guy, but Billy has made me feel so much better. He wasn't afraid to touch me, or kiss me, or do anything else with me. He even did stuff that I know wasn't easy for him — but he did it for me, and made me feel so good and so happy. I pretty much thought he was better than most guys I've ever known or met, but I found out tonight just what kind of guy he really is, and how special.'

That was when Sis surprised the hell out of me by adding 'Yeah, he surprised me tonight, too. I thought it was going to be kinda weird doing stuff with him, but it wasn't. I mean, sure, at first it was; but he never said or did anything to make me remember he's my brother. It didn't take long until I was just thinking about him as a guy, and not Billy. He was somebody I could trust completely, and not have to worry.' Then she turned her attention to me and said 'When we asked you in here, I was still a little worried about all of this… I mean, we have been doing, you know, sex stuff with each other, and I was afraid that it was going to be like when we were kids. Except that it wasn't; I was afraid that you weren't going to be as polite and understanding and everything as you've been. I was sure that you would say something to us about being naked, or doing things, or something — but you haven't, and it makes me glad you're my brother.'

I had to look back and forth between them for several seconds before I could think of anything to say in response to what they'd told me. I finally managed to come up with something, and looked at Charlene as I told her 'I can't know what it's like for you… but it isn't hard to figure out how I'd feel if it was me, and go from there. No, it wasn't easy to start doing some of the things I did with you — but it wasn't all that hard, either. You trusted me enough to share yourself with me, and I like you and care for you enough that I'd never do or say anything to betray that trust. You did things that made me feel good, and I was happy to do stuff that made you feel good, so there's no reason you have to thank me for that. Whatever I did that was different happened only because you're different… no so much the physical part, but as a person, different from Eva or anyone else.'

Then I turned to Sis and said 'Yeah, it was kinda weird for me, too, doing this stuff with you. But because you didn't make anything out of us being brother and sister, it was easier for ME not to. I know we fuss and argue sometimes, but I know we still love each other, too. Tonight, I was glad you're my sister, because I knew that no matter what else, I could trust you.'

Finally, I told both of them 'What we did tonight… I was nervous about it, too. What you said about not having anyone you could learn about guy stuff with, that's how I was about girls. I would have been glad to learn and do the things I did with just about any girl, but it being you two was something that actually made me happy. If anything like this ever happens between us — either me and one of you, or all three of us — I'd like that; but if you decide that you don't want to, then I can accept that and won't bother you about it. I really am grateful for what happened tonight, and proud that you trusted me enough that you were willing to let us learn about each other as much as we did.'

I had my arms around Charlene, and when I was done talking, she gave a contented sigh before snuggling a little closer. The smile I got from Eva told me that she appreciated what I'd said, too. The three of us just sat there for a little while, content to simply have each other's company; it was Sis that finally broke the silence to say 'As much as I hate to say it, Mom and Dad are going to be back before long. I'm not sure that there's enough time for separate showers even if Charlene and I shared one, so I think we'd better all clean up together — that is, if you two don't mind.'

I spoke first, saying 'Well, I suppose I could take a shower with both of you…' in pretend reluctance, and drawing a laugh from them. Charlene was next, saying 'After tonight, taking a shower or bath or anything else with either or both of you is fine with me.'

It took a little longer for all of us to get motivated, but we did finally get moving. Sis insisted on starting the shower and getting it adjusted, which left me free to simply stand back and hold Charlene in my arms. I started to get hard again from having her cute butt rubbing against my cock, and she turned her head to look at me impishly and say 'We don't have time for any more fun, remember, Billy?'

After giving her a hug, I started to play with her nipples before answering 'I'm not trying to get any more fun going, Charlene. That's just letting you know that I think you've got a really nice butt -

particularly when it's pushing against me like it is!'

Before she could make any kind of reply, Sis let us know that the water was ready; I helped Charlene into the tub, then she and Eva steadied me as I got in. As was to be expected, there was some figurative and literal grab-ass as we helped each other rinse off, but we somehow managed to keep it to a bare (heh!) minimum. Once we were all dried off again, I got dressed and headed back into the living room where I went ahead and ejected the movie — it was well past when it would have ended, and Mom and Dad had seen me starting it when they
