My wife, Tammy, and I live in a western state with our daughter, Jenny. My wife has always been a horny little thing, and our sex life has been very active. We also are an outdoor oriented family and spend as much time as possible at the lake or up in the mountains during the hot summer months.
Our best friends live next door to us. Tom and his wife, Jan, have a boy and a girl. John is 18 years old and Heather is 15. All of us had all decided to rent a cabin up near the high-country for the weekend. The cabin slept all seven of us comfortably. Tom, the kids and I, had decided to make a run down to our favorite creek, for a day of swimming and cliff jumping in the cool mountain stream. Tammy and Jan found out about an arts and crafts festival that they wanted to check out. We decided that Tom, the kids and I would drive down to the stream in his Jeep and Tammy would drive our Jeep down around noon with the rest of the supplies.
That’s where the plan first unraveled a bit. As we loaded Tom’s Jeep with a cooler and some bags with a change of clothes, it became apparent that there simply wasn’t room for two adults, two teens, and a girl. We finally decided that Jenny would have to sit on my lap for the 12-mile ride down the rough dirt road to the creek. Jenny was probably 80 or 90 pounds, so I didn’t think it would be too uncomfortable. Jenny had always been a pretty girl and as she blossomed, I knew I was going to be fighting off boys. Having said that, I never once thought of Jenny in any sexual context. I had seen her topless or even accidentally nude a few times in the year previous, but I certainly never entertained any inappropriate thoughts about her.
Everything was fine, until a few minutes after we hit the dirt road. That is when it happened. I suddenly realized that the jostling and having the weight of Jenny on my lap was starting to make me hard. I didn’t entertain any sexual thoughts of Jenny, it was simply the motion of the Jeep and her weight on my lap. I tried to will myself back to flaccidity and when that failed, I began reciting the periodic tables. It was useless. As the jostling continued, my cock grew to full size. I still hoped that Jenny hadn’t noticed, but then I saw her turn towards me with a quizzical look. Then she very discreetly eased her right hand under her butt and it came to rest on my rock-hard cock. She gave it little squeeze and pulled it away.
I was mortified. My daughter now knew that I had a raging hard-on. I just hoped like hell that she didn’t think I was having perverted thoughts about her. Jenny settled back against me as we continued bouncing down the road. I was a little relieved that she seemed to be ignoring my problem. However, as we went further down the road, I could swear that each time we rocked over a bump that she was actually wiggling her ass. The movement was not at all helping the swelling go down. I saw another bump coming up and braced myself. As we went over it, Jenny pushed back against me then slid forward dragging her ass over my raging hard-on.
My twelve-year-old daughter was grinding into my hard cock on purpose! That tidbit of information did not help my situation at all. I saw that we were getting closer to the parking lot, and I was flooded with relief. Only a couple more turns down the road and we would be there. However, Jenny wasn’t letting up. She was moving her little butt back and forth over my cock enough that I was worried that Tom or his kids would notice.
Suddenly, a new more urgent problem arose. It started feeling really good as she ground back and forth on my cock. I realized that if we didn’t park soon I was going to blast a world class load of jism in my drawers and all over my innocent daughter’s little butt. You see I have what my doctor calls hyperspermia. That is the overproduction of semen. Most men ejaculate about a tablespoon of semen. I ejaculate about a cup or more depending on how long it has been since I ejaculated. Even though I had a vasectomy after Jenny was born, I still produce a huge amount of semen every day.There was no way I could hide that from her and I started to panic. I thought of asking Tom to stop so I could…what…adjust my pants? Or maybe throw up? Have a look at the cute squirrel by the side of the road? No, I just needed to last a few more minutes. Now it was a race between Tom parking and me cumming. Tom pulled into a parking spot and shut off the Jeep just in the nick of time. He looked over at me smiling about to say something, but the smile turned to a frown as he said, “Damn, Jim. You Okay? You’re looking pretty red.”
No shit! I felt my juices receding and said, “Yeah I’m fine. Just a little warm in here.”
Jenny turned to me giving me a knowing smile, then she hopped out of the Jeep and suddenly my shorts tented up. Whoa! What now? At least Tom had already jumped out of the car and dropped the seat back so Heather could get out. I looked back at Heather to see her eyes locked on the tent in my trunks. When she looked up at me, she had a smirk on her face. Busted! Now I really was feeling humiliated. Heather probably thought that Jenny had given me a hard-on. Well, OK, she did, but at least the thoughts in my mind were pure as the driven snow. I grabbed a bag off the floor and positioned it strategically to cover my now waning tent pole.
We finished unloading the Jeep and we were soon all jumping off a cliff into the cool, blue water. That finally got me back to normal and soon I put the whole sordid mess out of my head.
Tom had been on the dive team in high school and college and he entertained us with one amazing dive after another. Playing in the cool mountain water and jumping off the cliffs made the hours fly by. I did catch Heather staring at me a couple of times, which made me a little uncomfortable. I keep myself in very good shape; I have to be since I’m married to a sexy Pilates instructor. Heather was a good-looking kid. About 5’8” like her mother, with a nice body and C- cup boobs. She was wearing a form-fitting blue one-piece suit that really accentuated her assets. She was also the daughter of our best friends and I wasn’t too happy about this new attention directed at me.
Around 1 P.M. I saw Tammy and Jan pull up to the parking lot in our Jeep. I marveled at the two women. Tammy is very petite, about 5’4” and 115 pounds, with red hair. Her mom was from Ireland with flaming red hair and her dad was from Sicily. She has red hair and blue eyes, but her skin has an olive tint to it and in the summer, she sports a beautiful tan. Tammy is a Pilates instructor and now runs her own studio, so she is in amazing shape. She has six-pack abs and great muscle tone. Her boobs are a very perky C-cups, and she has the best butt and legs I’ve ever seen on a woman. Although she’s 42 years-old, she looks better than most 20 year-olds. When she pulled off her shirt to reveal that she was wearing a small bikini top, every man in the place stopped to gawk at this beautiful creature.
Jan is much taller at 5’9” and about 155 pounds, with long blonde hair. She is curvier than Tammy, with D-cup boobs and a little extra padding. She is also in good shape, because she is one of Tammy’s customers. Even though my wife is the hottest thing I’ve ever seen, I have to admit that I fantasize about fucking Jan occasionally.
Now that the women had arrived, we unloaded the camp grill, camp chairs, and backpack coolers out of the Jeep and headed to our favorite spot about a mile up the stream. Lunch was amazing with grilled steak and corn on the cob and Jan’s amazing potato salad. This water hole here isn’t as crowded, but there are still a few of people around. It is beautiful, with a large waterfall that empties into a deep pool. The pool has a nice sandy beach across from the falls and cottonwood trees lining the banks.
I’d been horny all day and finally saw a chance to sneak off with Tammy for a mid-afternoon quickie. We took off upstream to another favorite spot. There is a smaller stream that feeds into the main stream and we followed that upstream for a few hundred yards to a small waterfall.
I couldn’t wait anymore, and pulled Tammy close and kissed her. She’s always been a very sexual woman, and her body responded immediately. I pulled off my trunks, freeing my turgid 8” cock. Tammy purred and dropped to her knees in the pool and sucked it into her mouth. I only let her suck me for a minute and said, “Babe, I’ve gotta be inside you now!”
No argument from her, as her clothes came off. She laid back on a small boulder; legs pulled up and spread in invitation. When I entered her, a shudder ran through both of us. I buried my cock to the hilt and then started pumping into her, as I circled my thumb on her clit. I felt my need rising…and then it happened. Completely unbidden, a vision played through my mind of Jenny rubbing her cute little butt back and forth across my dick. Then another of her turning and giving me that coy little smile as she got out of the Jeep. The speed and intensity of the orgasm completely took me by surprise. I blasted all the semen I tamped down earlier and more into Tammy’s waiting womb.
When I pulled out of her, my seed gushed out of her like a white waterfall. That’s when I caught some movement out of the corner of my eye. Up on the bank to our right, was somebody wearing a blue swimsuit standing behind a bush. She had witnessed the entire episode. Oh my God, it had to be Heather! First seeing me with a hard-on, and now this. I was about to say something to Tammy, but the girl turned and quickly headed up the hill. That’s when I saw the red hair. Oh my God, my own daughter had just witnessed me fill her mother with an unnatural amount of cum! Suddenly I was at a loss for words, so I did what I do best...nothing.
Tammy looked at me with a dreamy look and said, “What got into you, cowboy? You know if the construction business ever goes bust you really do need to get a job as a porn star.” We both chuckled at that.
When we got back to the water hole, Jenny was there with Heather. She was bent over facing away from us, with her legs parted slightly. My eyes wandered up her toned, athletic legs. The fabric of her swimsuit barely covered her pussy, and I could easily see the crease of her little slit. The back of the swimsuit had ridden up revealing the soft, round globes of her cute ass. When she stood up, I couldn’t help but study the rest of her lithe, little body. She was only about 5’ tall. She had her mother’s red hair and a cute little sprinkling of freckles across her nose. She had begun her menstrual cycle about 6 months earlier, and she was developing nicely. I’d never noticed her boobs before, but as she turned to the side, I couldn’t help but notice them. They were A-cups, but on her tiny frame, they really stood out. She was wearing a kid’s swimsuit that was a size too small. There was no padding in the cups, so I could see her hard, little nipples straining against the fabric. Shit! I was getting hard again, so I dove into the water to cool my body and my mind. I thought, “Shit Jim, what the hell. You're all turned on by seeing your twelve year old daughter. What kind of pervert does that?”
She saw me and was right behind me. She said, “Hey dad, Heather and I want to play a game of chicken with you and Uncle Tom.”
The kids had grown up with Tom and Jan, so they always referred to them as uncle and aunt. Tom and Heather got in the pool and the girls climbed onboard. The first game, Tom and Heather managed to push us over. As we dumped into the water, Jenny got turned around and her crotch pressed right against my face. I was getting turned on again, but quickly refocused as she climbed back up for another try. This time, we managed to push them over. As we waited for them to recover, I became acutely aware of the heat on my neck coming from Jenny’s crotch. I could swear it felt like her bare pussy was rubbing against me neck, but I figured that was just my newfound perverted imagination at work.. Thank God the water was above my waist, because I was sporting another raging hard on.
The third round we, both managed to stay on our feet for a while, even though Jenny was distracting me. Finally, all four of us fell at the same time. As we tumbled in the water, Jenny turned around again so that my face was in her crotch. I opened my eyes. What I saw was blurry, but unmistakable. She had her legs spread with the fabric pulled to the side, revealing her little virgin pussy to me. I resisted the urge to stick my tongue out and lick her slit. When we came up I looked at Jenny and she acted as if nothing had happened.
I sat with Jenny a while. We chatted about all things she wanted to do during the summer. I brought up the subject of boys, but she told me she wasn’t interested in boys at all. I thought that was interesting considering the events of the day.
On the hike back to the Jeeps, both Jenny and Heather were right in front of me. I really couldn’t help but watch as their cute little butts swayed back and forth a few feet ahead of me. I couldn’t believe what a pervert I'd become! But, Damn, They did look good!
During the drive home, I tried to get a feeling for any changes in Jenny, but she just acted like her normal, bubbly self. I wondered where all this was leading.
