Hi, I'm Lisa and I've never written anything for these kinds of websites although my brother and I have read quite a few. So, if my English isn't perfect, please be nice about it, I'm trying.
So, how to start? At the beginning, I guess, at least the beginning of the situation with my brother and me with our new neighbors, Steve and Sandra.
As I said, I'm Lisa and I'm fourteen, I'll be in high school in the fall. Most of these stories tell you what the people look like, I'm five foot-two with long blond hair, usually in a ponytail. The guys reading this will want to know that I'm considered quite pretty and my measurements are 34B-22-34 and I weigh one hundred and ten pounds. Yeah, you guys would like me, I look great in a bikini. I guess even better in nothing at all.
Now my brother, Kenny, he's two years older, sixteen and will be a junior in the fall. He's really cute, well, handsome, I guess, more these days, stands five feet-ten, has streaky blond hair, isn't really athletic but has some nice muscles and, well, he looks pretty good in his swim trunks and that's his sister saying it.
The two other people, the ones that moved in about a month before this all began, they're Sandra, I now know she's twenty-four, stands at five-five, has curly blond hair and is 36B-24-36, weighing about one-twenty. She looks terrific naked but I'll get to that in a minute.
Steve, well, Steve is twenty-six, six-one, has brown hair and has a beautiful, long, thick cock. You'll soon find out how I know that but, to finish up, they are both shaved in their pubic area. I am, myself but my brother isn't. Well, wasn't, he is now. You may wonder how his little sister knows this, well, that's coming, too.
So, here's how this started.
My brother and I have always been close and have talked about all kinds of things. As we've become teens, of course, some of that has been about boys and girls and sex.
We did some show and tell when I was eight or nine, looking at each other's genitals, the typical stuff, and even played with each other some after that. That began to change about two years ago when I began sprouting boobs and Kenny was fascinated by them almost as much as I was. I loved having boobs, I loved showing them to Kenny, I loved how he loved them.
When he first sucked them, well, can you women remember the first lips to suck your nipples? Oh, it was the best. He was attached to my boobs a lot after that. I loved it. I was also now giving him handjobs which I loved.
When I made his cum first spurt out the end of his dick, well, I knew he was in for a lot of stroking from his sister. I quickly had him masturbating me and then it was only months before we were doing oral like so many kids we knew.
We would have been fucking, I'm sure, if I'd been on the pill but we were both just deathly afraid of me getting pregnant. So, it kept us, like a lot of our friends, at the oral stage, not that that is so bad, it's really pretty wonderful.
So, we were very sexually involved with each other, very happy with it, loved loving each other's bodies, just relishing in the physical sex we were having.
We often spent our summer days naked in the house, just enjoying our sexuality together, there was no embarrassment or shame or shyness between us. It was wonderful.
We did have new neighbors, a young married couple, Steve and Sandra, who we met when they moved in. They had our parents and us over after they were in a few weeks. They're a really handsome couple, really nice.
Then a few months later, during the summer, Kenny came in my room, I figured he was looking for some sex with his little sister but I was wrong.
"Hurry, come on, wait 'til I show you what I've been looking at, come on," and he pulled me up off my bed by the hand and I followed him down the stairs and into the kitchen where he stopped.
"Now, you've got to be quiet so they don't hear us. Quiet, okay?"
I nodded and we went outside and I followed him over to the hedges that separated our yard from Steve and Sandra's.
He pointed and I looked.
There they were, laying out in the sun next to their pool on a blanket ... naked. Her hand was over slowly stroking his dick as they lay there with his hand on her bare boob.
They were beautiful, just beautiful. We had seen them, of course, but now, naked, well they were stunning. And, oh, so sexy.
Kenny had his hand on my boob up under my teeshirt as we watched. Oh, I was so wet watching them, then she moved, got up on her knees and took his dick in her mouth to suck, her butt facing us showing us her pussy glinting in the sun between her thighs.
Kenny leaned in to get a better view.
"What are you two doing?" Steve's voice called out. Sandra raised up and looked over our way.
"I know you two are there, I saw you both move. Kenny, Lisa, come around and in the gate. Right now. I mean it."
"Oh, shit, Lise, they've seen us. What do we do?" my brother whispered.
"We go over there. What else? They can tell our parents we were spying on them."
So, we both slowly went around and came through the gate into their backyard.
"Over here, come over here," he said and we both slowly walked over to them on the blanket.
I couldn't believe it but they just sat there looking at us as we walked toward them, still naked, not trying to cover themselves, I was so nervous and so turned-on, it was crazy.
"So, you two get a good eyeful?" Sandra asked.
"Well, uh, we ... well, I saw you and got Lisa to come look, it was really my fault," my brother owned-up.
"And you watched Sandra giving me head?"
"Uh, yeah, kind of, yeah," Kenny told them.
"You two want to watch me finish sucking him off?" Sandra asked.
We both just stood there. I mean what would you have said?
"Well? You wanted to see. Do you still? My poor guy is still horny because you interrupted a nice blowjob I was giving him. Look at his poor cock, all hard and ready, so horny," she said as she lifted his dick in her hand.
"Um, yeah, okay," my brother said.
"Well, if you're gonna watch, then you've got to get naked like we are, go ahead," Sandra said.
I looked at Kenny and he looked at me, then he started pulling off his teeshirt. I guess we were getting naked with our next door neighbors. My brother was soon standing there with his long cock sticking out as I slowly began taking off my shirt. I guess it was time to get naked. I wasn't wearing a bra underneath, I usually didn't when we were home alone, Kenny often wanted to see and play with my boobs and, well, I loved it when he did.
So, I slid off my shorts and panties and stepped out of them now all of us naked in the bright, warm sun of the afternoon.
"Go ahead, sit down," she said and then got up on her knees, bent over her husband's cock and took it in to suck.
It was fascinating to watch her, holding the long part, twisting her head around as she sucked the end. Then, she shifted over and swung a leg up over him and lowered her pussy down as he began eating her out.
Kenny and I often did the same thing but watching someone else do it, especially a beautiful pair like they were, it was so, so sexy. I soon had my hand between my thighs rubbing as my brother slowly stroked as he watched.
They went at each other, so hot, so sexy, I finally moved over to Kenny and stroked his cock for him as he fingered me while we watched. I think much of our nervousness was now replaced with sexual arousal, you just don't sit idly by watching a couple giving each other oral sex and just wonder about tomorrow's weather.
They were both moaning, the sun shining down, a little perspiration on each of them, then Sandra began to buck up and down over her husband's face. I knew she was close, I'd been there many times myself. Then she raised up off him, crying, "Oh, god, I'm cumming, more, Steve, mmm, more," and she was jacking his dick as she licks all around the top as he started spurting his white cum up onto her face and mouth as she dropped down to suck the rest.
Kenny rolled me over and got up over me to drop his head down between my legs as I gripped his dick and began sucking. We were in a sexual frenzy at that point, I don't think either of us was really thinking about what we were doing except for just doing it.
We were much more wound-up than usual, we just attacked each other and were soon getting each other off and just fell on each other at the end exhausted and happy.
"Well, you two seem to know each other better than many brothers and sisters," Sandra said.
Kenny had moved off me and replied for us both, "Well, yeah, I guess that's true. You'll keep this just between us, right?"
"Oh, don't worry, guys," Steve replied, "we think we'll all get along just great together. We already have been like this, naked and having fun together."
"Yes, I think the four of us could have lots of fun together if we wanted to." Sandra added. "Kind of grown-up fun, if you know what I mean."
Kenny looked at me when she said that and I shrugged my shoulders not knowing exactly what they had in mind though I was wise enough to know it was all about sex.
"Why don't you two tell us how far you've gotten with each other. Are you fucking?" Steve asked.
"Oh, I wish," Kenny replied, "Lisa's not on the pill and there's just no way we'll risk her getting knocked-up. No way."
"There are ways to prevent that, you know," said Sandra, "There's spermicidal gels, condoms, a sponge-thingy you put inside, for a few. These you can get at a drug store."
