My aimless wandering had led me to the small playground, where finally I sat down in one of the swings. I had not realized how long I had been sitting there, lost in thought, until my growling stomach reminded me I hadn't eaten since breakfast, ten hours ago. As I looked at the time, I was surprised to see how much time had passed since mom and I had exited the bath house.
All around me, the almost deserted campsite site was coming alive with the families that returned from their various daytime activities. It reminded me of my own family, who was probably waiting for me at the caravan, so I quickly got up and walked back. When I got there, dad and Nick had returned as well and were all dressed up and ready to go.
The restaurant mom had picked was an old diner not far from where we rented the horses. According to the campsite manager, this place served the best steaks in the country. An hour later the four of us were sitting at a small table in the very small restaurant with four big, juicy steaks in front of us. It could very well have been the most delicious steak I've ever had in my life, but my mind wasn't really into it. I kept thinking about the stranger's cock I had sucked and how mom had fucked him right in front of me.
Luckily, my father and Nick were too pooped to notice it. Only mom knew what I was thinking and gave me a playful wink while she enjoyed her steak and salad.
That night in bed it was even worse. I lay awake for ages, contemplating the things that happened, feeling frustrated and horny as hell. I vividly remembered how the stranger's tangy sperm had filled my mouth. It was like I could still smell it, but then I realized that might also be because my brother was feverishly jacking off in the bunk bed above me. Even our parents had fallen asleep ages ago, but my brother wasn't even slowing down yet. He had been masturbating almost non-stop for an hour now. I had heard him grunt in orgasm at least four times, but it didn't seem to give him the release he apparently needed so badly.
"Nick, do you mind? I'm trying to get some sleep here" I whispered, a little annoyed.
The rhythmic creaking stopped for a minute, but slowly and softly it started again.
"Aren't you afraid you'll wear it out like that?" I whispered.
"I can't help it, I can't sleep when it's this hard" he grunted.
Part of me was feeling a little sympathetic. I'd give almost anything to be alone in my room right now. Just me, my pussy and my hairbrush handle, surrounded by four thick walls that blocked any sound I might make. I wish I could be as impartial to the rest of the world as my brother was and give my pussy the release she so desperately needed, but even the experience in the showers had not changed that.
"You can't tell anyone, but I fucked a real woman today" Nick suddenly whispered.
We weren't actually that close, my brother and I, but I guess he just had to tell someone. Since there was no-one else, that someone was me. My brother's conquests were not something I was hugely interested in, but, as a good sister, I asked him to tell me more. Maybe we would finally get some rest once he got it off his chest.
"It wasn't, like, my first time or anything, but a real woman with lots of experience is so much better than a girl"
Great. If his easy girlfriends weren't even good at it, what did that have to say for a complete virgin like me? Maybe it was a good thing mom was giving me this opportunity to learn from her and practice with strangers via the glory hole
"So, who was this woman?" I asked.
"Well, eh... you see... I don't know... I mean, I haven't actually seen her face, and we didn't speak much, but she really knows how to suck cock. I know she's got a big, round butt and she was incredibly wet. Best of all, she really knows how to move and use her muscles. Every time she came, I felt her pussy squeeze my cock"
"So you made her cum too?"
"Oh yeah, like three or four times!" he said proud.
"But you have no idea who this woman is?"
"It... it's kind of a long story"
I wasn't going to get any sleep anyway. I may as well hear it.
"Tell me"
"Well, it started when dad and I were in the bath house. Dad said we had to share a shower because those fucking coins are so expensive."
"Yeah, I know. Mom and I shared too" I said, feigning a shared discontent. I didn't want my hormone-crazed brother to know how much I had enjoyed the salacious acts that transpired in our stall.
"Wasn't it weird to be naked with dad?" I asked, thinking back to when I had to undress in front of mom.
"Yeah, it kind of was. But, you know, me and the guys always shower together after practice. With dad it was just like that. At first."
"At first? What happened?"
"Promise you won't tell?"
"Yeah"
"Dad had a huge boner, and I mean, huge. But that's not all. Just as we got naked and dad turned on the water, this woman puts her fingers through this hole on the wall and taps it a few times. So dad walks up to it, and then he sticks his cock in the hole!
I thought he looked kinda stupid, standing against the wall, but then he starts groaning and he's saying things like 'Oh yes, suck it'"
With a shock I realized, that's exactly what I did! That woman could have been me! But then I remembered Nick and dad took their shower well after ours, I had even seen Nick wait for dad as I strolled home.
"And what happened next?" I asked, my heart pounding in my throat.
"I don't think he came then, but he steps back and says I should try it too"
"So, did you?"
"Hell yeah!"
"What was it like?"
"At first I was a little uneasy, I mean, you don't know what's gonna happen and you can't see shit. But she really knew how to suck cock, that was like the best blowjob ever. She even let me cum in her mouth and I think she swallowed, too."
"Didn't you say you fucked her as well?"
"Yes I did. But dad fucked her first. After she let me go, he took his turn again and stuck his boner through the hole. It wasn't long before he started grunting again and I could feel the entire wall move as she fucked herself on his cock. Dad started thrusting too and saying how good it was. I think he came and then he said it was my turn again.
My dick was all hard again, so I poke it through the hole and the next thing I know, the woman grabs my cock and puts it inside her."
The more I listened to my brother's story, the more it started to bug me. It sounded suspiciously much like the experience I had with mom. Too much to be purely coincidental. Both our parents had been more than eager to exploit the hole and to have us involved. In both our adventures there happened to be someone in the other stall that was just as eager to participate. It was beginning to look more and more like it was one big set-up.
My brother was oblivious to any of this, he was still going on and on about the woman he fucked.
"I couldn't move much, because of the wall, but what she did was awesome, I never felt anything like it and I think she came again, because her pussy began to squeeze and then I came too and I shot it all inside her. Man, I never done that before! But she didn't stop fucking, she kept going until she couldn't take it anymore and then she sucked me until I came again, in her mouth.
After that we were all kind of tired and then we had also ran out of coins, so we quickly rinsed off and got dressed. I told dad I wanted to go see who it was, but he said I couldn't"
"You couldn't? Why not?"
"He said the women only did this because it was anonymous, and we had to respect that, because if we didn't, they wouldn't do it anymore."
"Well, that makes sense. So that's why you don't know who it was?"
"Exactly"
"Then what happened?"
"Nothing, really. We went home and waited for you and mom. You know the rest"
There was one thing that bugged me more than anything else. There were eight or ten stalls in the women's showers, so presumably also in the men's part. Yet, both Nick and I had ended up in the only ones with the hole. It was like they had guided us deliberately to the showers with the hole, as if they had known it beforehand.
Wait a minute, didn't mom go to that stall on our first day?
"Do you think dad had a reason to choose that particular stall?"
"I don't know, they all looked the same to me. Why?"
"Oh, nothing really"
But why would they want to have us involved too? If they wanted to fuck a stranger in the shower, wouldn't they better go alone? While it wasn't unthinkable mom might have wanted to teach me a thing or two, Nick surely didn't need any coaching. There were lots of girls willing to fuck him, and apparently he did. Dad had nothing to complain about either; mom was ready to fuck him day and night.
Come to think of it, where exactly was mom during all this?
With a shock it suddenly all made sense. All the little pieces of the puzzle fit together. Mom had explicitly sent me back to the caravan alone, thereby making sure she would be on her own and able to do whatever she wanted. Or rather, whoever she wanted,
The mystery woman that Nick kept going on about was none other than our very own mother! Just like the stranger I had sucked off must have been our dad! They had purposely planned everything from the start, and it had worked!
I was shocked our parents had played us like that, and even more shocked when I realized the reason they did it was because they wanted to have sex. Only not with strangers, but with us, their kids.
"I know who the girl was" I said.
"I don't think so"
"Yes I do!"
"Yeah? Who is it then?"
"Could you see her pussy? Was it shaved?"
"I don't know about the top, but the lips were as smooth as a little girl's"
"Then let me guess... Was she moaning so loud you were afraid everyone would hear?"
"Yeah, she kind of did" he said. I could almost hear the embarrassment in his voice.
"And did she really slam her butt at the wall when you were fucking?"
"Yes. How do you know all this? Were you there also? Did you hear us?"
"No, I was walking home when you were in the shower. But tell me, when you made her come, did she squirt too?"
"Yes, she did! How do you know all this?" he asked, perplexed.
I chuckled softly.
"Dear brother, you have fucked your own mother!"
Nick was silent for a minute.
"Shit" he muttered. "I thought she sounded familiar"
He was silent for another minute, trying to accept or justify his deeds.
"How did you know?"
"They did the same to me earlier"
It was now my turn to tell what happened during my shower with mom. I told Nick how beautiful she had looked and how she brazenly shaved her pussy in front of me. I told him about mom's reaction when I discovered the hole in the wall and what happened next.
As I described mom blowing and fucking the stranger, the bed above me started shaking again. It would be hypocritical to tell Nick to stop. Not when my fingers were also between my legs, softly circling my little nub as I told my story.
I even told him about me sucking the guy's cock and swallowing his cum, but skipped the part where mom and I ended up in each other's arms and kissed. I finished my story with me walking home alone.
"So... that stranger was dad?" Nick asked when I stopped talking.
"I think so."
"At least you haven't fucked him"
"No, not yet"
"But you are going to do it?"
I related to Nick the conclusion I had come to before. I had loved it way too much not to continue.
"Even if you know it's dad?" he asked.
"If you had another opportunity to have sex with that woman, wouldn't you take it? Honestly?"
"You're right. I fucking would" he sighed.
"Val?" Nick said after a while.
"Yes"
"Do you think they'll let us do it again?"
"Probably"
"What if it wasn't dad... I mean, what if it was my turn? Would you fuck me too?"
"Gee... I hadn't thought about that."
"Do you think they'll let me fuck you?"
"Maybe"
"I hope so"
