The new girl

left.

With that out of the way, it was back to my room; as I passed Eva's room, I saw that she and Charlene hadn't bothered putting anything on, and both of them posed for me briefly, then smiled and blew me a kiss when they saw me looking at them. I went ahead and closed the door to Eva's room, then went into my room and closed my door, as well. Perhaps twenty minutes later, we heard Mom and Dad get home and call out to see if we were still up. When they learned that we were, they said they were going to bed and wished us a good night. I couldn't help thinking to myself 'I've already had one, and it was way better than just 'good'!'

It was roughly a month later, and Charlene was spending the night with Sis again. Our folks were going out to a retirement dinner for one of the people that Dad worked with, and the two of them wanted me to join them again. Our second session together went much like the first; the big difference was that because we didn't have to start from the beginning, we were able to get a lot more pleasure out of the lesser period of time we had: each of them gave me a blowjob all by herself while I was eating the other's pussy. Between rounds one and two of that, we used the opportunity to get even more familiar with each other's bodies and comfortable about touching each other. Before we went in to clean up, Sis was on my lap toying with my semi-erect penis as I played with her nipples; Charlene was stretched out next to us, softly stroking my balls while I gently caressed her incredibly firm and smooth ass. We got dried off and dressed just a few minutes ahead of Mom and Dad getting home.

I was just hanging out in my room during the day when Sis came in. Charlene was out with her mother getting ready for the start of school (just a few days away), so it was just the two of us at home, since Mom was at the Senior center where she volunteered 3 days a week. I just looked at Eva with an eyebrow raised in question, and she gave me this strange grin as she said 'I'm feeling really horny, and I really want to, um, taste your juice. It's just us, and nobody'll be home for at least a couple of hours… think you'd like to, uh, fool around for a while?'

Her question threw me for a number of reasons. For starters, it was the first time she'd ever indicated she wanted anything to happen between us without Charlene present; and for her to come right out and ask me that way…

Even knowing that something else was going on with her, the idea of getting a blowjob and a taste of Eva's pussy was too much to pass by. As soon as she saw my grin, she started taking her clothes off -

suprising me again when I saw that she didn't have panties OR a bra on under the dress she had on.

Well before I was rid of my undershorts, she was laid out on my bed; when I climbed onto the bed with her, she said 'You've heard about '69', haven't you?'

I said that of course I had, and she continued 'I want to try that… it sounds like it would be really fun…'

'It does to me, too', I answered. 'I think you should probably be on top, though, since you don't weigh as much as I do.'

She nodded her agreement, and I got myself positioned next to her but 'facing' the opposite direction.

She quickly moved to her hands and knees, and then moved over me; it was only a few moments before we were properly situated.

Both of us took a few moments to look at the other from our new perspective, and I found myself delighted by the new view I had of her: I could still easily see the trim strip of her bush around the glistening labia that split it, but I also had a great view of her tight little ass. Charlene's ass was terrific, but Sis' wasn't far behind (so to speak). The first thing I did was to move my hands up so that I could start caressing and squeezing the wonderful globes of my sisters butt; once I'd done my best to memorize the sight of it, I raised my head and stuck my tongue out so I could run it along the cleft of her sex, starting at her clitoris. Even as I was learning just how wet and aroused Eva already was, she moaned her pleasure at what I was doing before lowering her head and taking my entire cock into her mouth.

I knew that I was in for a truly novel experience when Sis went about getting me hard, but without using her hands even once. Purely through judicious use of her tongue, lips, mouth, and suction, she managed to bring me to full erection without once losing contact with my manhood. It was something no other woman has ever done, and I still treasure it to this day.

Knowing that we had plenty of time and privacy (Sis had closed my door before letting her dress drop to the floor), both of us took the time to not only pleasure our partner, but enjoy ourselves as we slowly and steadily got each other more and more worked up.

Without bothering to say anything to each other, we both went about pleasuring the other so that our climaxes would happen more-or-less together: Eva was content to basically just entertain herself with my cock to start with, while I was more interested in getting her aroused and bringing her as much pleasure as I could. That made it possible for me to bring her to an initial orgasm that had her nectar practically flowing out to where I could happily lap it up. Once she'd recovered from that release, she gradually increased the amount of outright stimulation she gave me. After a bit, I realized that I could tell how relatively excited she was by how much she was doing to get me going. What she was doing felt damn good, and I finally reached the point where what I wanted more than anything else in the world was to unload my balls in her warm mouth; to encourage her into making that happen, I got serious about what I was doing to her by doing more and more of everything that I'd learned she liked.

After a bit, it turned into something like a race — but not the kind anybody really loses: both of us knew that we were both going to cum like gangbusters; the only question was which one of us would be first.

As it turned out, it was me. When she took as much of my hard penis into her mouth as she could (I could feel it touching the back of her throat!) and used her tongue to massage it all along the underside, it was more than I could stand and I sprayed what felt like gallons of cum directly into her throat as she eagerly swallowed every drop of it.

She got her 'payback' as soon as I could manage it, however. I decided to try something new by trying to fit as much of my tongue through her vaginal entrance as I could… while using my bottom lip to kind of massage her exposed clitoris. That combination had the desired effect, and it wasn't but a minute or so that she began nearly convulsing on top of me from the force of the spasms her body went through.

Once Sis had gotten herself back together, she let me help her move off of me; I swapped ends, and she indicated that she wanted us to spoon — something I was happy to do. When I put my arm around her and cupped her breast in my hand, she released a happy sigh before putting her hand on mine. The two of us had been laying there for a few minutes when I heard her ask 'Billy? What would you think about it if a brother and sister were doing even more stuff together than we do? I mean, do you think it would be wrong or anything if they actually had sex with each other?'

Coming out of nowhere like that, the question completely threw me… though it did seem to explain what was going on with her; it didn't take a genius to figure out that she was thinking about the two of us becoming even more intimate than we already were. Still, the question itself wasn't something I'd given any thought to — I was already experiencing more with her and Charlene than I'd even dared dream about.

When I'd been silent for a couple of minutes, thinking about what she'd asked, she turned her head a bit to query 'Billy? Did you hear me?'

That prompted me to run my thumb across her nipple as I answered 'Yeah, I heard you. I never thought about anything like that before, so I'm trying to figure it out now.'

'Oh. Okay.'

I continued to caress her breast and idly toy with her nipple while I figured things out, and got my thoughts organized so I could talk to her without botching things. When I was ready, I cleared my throat and told her 'I don't think that a brother and sister having sex with each other is automatically a bad thing, but I do think that it could turn pretty bad awful easy. More than anything, I think it's something they'd have to be real careful about, in a lot of different ways.'

'What do you mean?'

'About the first part, or the second?', I asked, already knowing what the answer would be.

'Both.'

Taking a deep breath, I began by telling her 'For it not automatically being bad, that's just what I mean.

If both of them are doing it because they want to, and neither one of them is forcing the other, or taking
