My first experience with voyeurism was so exciting I have to masturbate almost every time I think about it. It's burned into my mind like a videotape. The fact that I got to share it with my girlfriend and that she was and is as excited about it as I am adds to the eroticism of the whole thing even more. When you throw in the fact that we watched a virgin being taken by her father, it becomes mind-blowing. The mountains in California make for amazing camping. The area that we stayed in was gorgeous, though I've heard that it got some damage from recent fires out that way. There were lots of areas to hike that you wouldn't run into people for hours if you didn't want to. My girlfriend, Toni, had family out that way, so we visited with them and then went to camp for a while. We were in that sexually charged point in a relationship where we couldn't get enough of each other's bodies, so it was a lot of fun, swimming, hiking and fucking like bunnies back at the tent. Although we could hike without running into people, the actual camping area was not private. We tried to keep some decency about us when fucking, though Toni couldn't quite help herself the first night when I was licking her clit, and she moaned through an orgasm as I buried my fingers inside of her. We had neighbors in every direction, but everyone tried to be cool and I honestly don't think anybody heard us. One of our neighbors was a family of five, with two tents on the site. We met them while taking our trash to one of the bins, and they seemed nice enough. The couple was in their late thirties or early forties, with a son of about 14, and two daughters of 18 and 13. Tom was the son, Jessie was the 13 yr. old and Elizabeth was the virgin I mentioned. The family was the Jays and they were an attractive family, but I really wasn't as interested in them as I was in Toni, who I always let walk in front of me so I could see her terrific ass while we walked. I was cordial to them, of course, but didn't think much about them until we were on a hike the next day. Toni was, as usual, a few steps ahead of me. Toni was not wearing a thong that bared her whole ass, but the bikini she was wearing was probably not ideal for a hike. Fortunately the path was fairly well marked, and we had intended to make our way up to a branch in the stream where we thought we might get some private swimming, and maybe playing time. On the way we paused for the occasional grope, hands beneath swimsuits, my cock at a steady swell in anticipation of later activity, her pussy wet from the sun and the warmth and my hand occasionally on her stomach, or her nipples. We made sure the process was as important as the result. When we got closer to the stream, our pre-coital flush dropped down a notch or two as we heard voices ahead. "Damn," I thought, "I'll have blue balls by the time we get to do anything." We really weren't trying to sneak up on them, but Elizabeth and Mr. Jay were fairly oblivious to our presence. As we got closer, I was a little surprised to see that they were naked. Elizabeth was a very attractive young lady. Her hair was cut short, but feminine, a brownish blonde, she had the breasts that all girls hope for, smooth, unmarked skin with pinkish nipples. Her stomach was flat and her pubic hair was sparse. I stood speechless for a moment. "Probably just nudists," I whispered, closing my mouth and trying not to let Toni see that I was openly gawking at a naked 18 year old. I looked at her and noticed that she too was staring. "Yeah, probably." She replied. I reached up and took her hand, trying to lead her down another path that I thought might let me get to fuck her. I needed to do it soon now. Elizabeth had not slowed my arousal at all. Just then, Mr. Jay, daddy, picked up Elizabeth and threw her into the water, splashing and laughing and generally having a good time. It was obvious that they were not uncomfortable naked around each other, confirming our suspicions of nudism. "Wait," Toni said, almost too loud. I really didn't want to get caught peeping at these two, though they were the ones standing there naked. "Look, daddy's got a hard on." Toni said. She was right. During all the wrestling and throwing each other around, Mr. Jay's dick had started to rise. He was kind of looking at Elizabeth and then looking back at his clothes on the side of the stream. Abruptly, he stopped the playing and headed towards his clothes. Elizabeth stood in the water, about thigh high and told her dad to come back. "I can't Elizabeth, we need to head back." Elizabeth was obviously puzzled and she ran up and grabbed her father from behind before he made it to the side. Her breasts were pressed up against him, and she jumped and threw her legs around his waist. "I'm going to dunk you!" She shouted, trying to get her father back into the midst of the stream to play. "Elizabeth, please!" Her father was almost angry with her, but he removed her from his back and put her down gently. It was then that Elizabeth figured out the real problem. She saw her father's erection and stood still for a moment. Her daddy could tell she was staring. Though it was only a second, to Toni and I it seemed an eternity. Given a sofa and a bowl of popcorn, we would have sat back to watch events unfold. "It's ok, daddy, I've seen Tom's hard on before, it's not your fault." Definitely nudists, but that didn't stop Toni and I from dropping our jaws again. This girl had seen her brother and now her father at full attention. If she could have seen from her sunlit spot in the stream, to the well shaded area from which we watched, she could have seen my hard on too. It was throbbing. "Are you going to play with it?" Elizabeth asked, no malice, no embarrassment in her voice. Mr. Jay was staring at Elizabeth, taking in her naked form. So was I. Toni was too. In a distracted way, Mr. Jay was already stroking himself, absent-mindedly, slowly. Elizabeth watched his hand. Mr. Jay's voice was almost robotic. "I don't think we should be talking like this. It's not appropriate." Elizabeth seemed to be a cheerleader by nature. She might as well have said "c'mon daddy, you can do it, put a little power to it." Instead she told her father "It's ok, you and mom said so. I play with myself too." With that, Elizabeth moved her hand down to her pussy, and cupped it. Mr. Jay groaned. Elizabeth groaned. Toni and I groaned. Within a fairly small space in the woods, four people were masturbating. Mr. Jay moved closer to Elizabeth, and soon hands were swapped. Elizabeth's small hand was rubbing her dads cock, Mr. Jay's hand was rubbing his daughters pussy. Toni and I went further. We didn't say it, but we both wanted to keep watching. Toni went to her hands and knees and in seconds I was behind her, and then inside her. I almost came as soon as I put my cock inside her wet pussy. Mr. Jay was now kissing his daughter, licking her neck, her ears, her face, as they rubbed each other and moan. I would give anything to have been up close, watching as his fingers penetrated her, to see the semen leaking out of him as it left trails on her skin. At this point, they're speech become too low for me to hear, but I imagine it as things like "Oh Elizabeth, we shouldn't..." "Daddy, that feels so good." "Mmmm, my baby girl." "Oh, daddy, oh daddy." Meanwhile, Toni and I were moving slowly, already breathing as if we'd fucked for an hour, but knowing that if we came now, we'd regret it. My hands were on her hips, and I wanted nothing more than to pull her back hard against me and shoot deep insider her. Actually I did want something more. I wanted to see Mr. Jay fuck his daughter while I fucked Toni. I love it when I get what I want. I don't know if Mr. Jay knew he was going to do it, or if it was just a sudden thing, but in a split second, he lifted Elizabeth, wrapped her legs around him and plunged his cock inside her in one motion. Again time seemed to stop. Elizabeth's head whipped back, her teeth clenched. Her father's face was knotted. I swelled inside of Toni, mentally working to not cum yet. Toni moaned. And then with a sudden release, we were all fucking furiously. Mr. Jay lifted Elizabeth and thrust his cock into her again. She was easy to hear now, just one word, daddy, over and over, mixed with ohs and nnnnn's and grunts that seemed to come from deep inside both of them. Elizabeth's arms were around her father's neck, helping lift and pull. She was grinding her young cunt against him, taking her father's cock deep inside her. I was crouched over Toni, my chest against her back and neither one of us cared who heard us. We knew Elizabeth and her dad couldn't. The moaning from the two of them was constant. It was hard to keep my eyes focused on them, but I wanted to. Toni and I were fucking to the same rhythm as Elizabeth and her father. We've talked about it since, and though Toni and I didn't say it at the time, we were definitely roleplaying. I was Mr. Jay and she was Elizabeth and we were fucking each other silly. It didn't take long for any of us at this point. From the time I first entered Toni until we all finished couldn't have been longer than ten minutes. But it was fabulous nevertheless. We were all sweating, Mr. Jay's arms were bulging, his hands under his daughter's ass, lifting her. Elizabeth's hair, damp from perspiration, her forehead resting on her father's shoulder. Her arms lifting, straining around her father's back. Toni and I pushing, pulling fucking, my cock plunging into her, my crotch against her ass. Her pussy slightly frothed with the motion. We were in pure, animal heat, all of us. If anyone had touched us we would have killed them or fucked them or both. Then we were all coming at once. Elizabeth screamed "Oh god, Daaaaaddddyyyyyyyyy." and we were off to the races. I pulled Toni's ass hard against me, and began shooting what felt like quarts of sperm deep inside her. After the second shot, Toni gave a another grind and her cunt began spasming, milking the remaining cum out of me. Mr. Jay shot what I'm sure was a load equivalent to mine deep within his daughter. His knees buckled and I thought for a moment he might drop her, but he held up and slowly kept lifting her, cooling down from the fucking as Toni and I did the same. Mr. Jay and Elizabeth took their time getting back to the side of the stream. They were very sweet with one another, holding hands as they walked back, kissing, fondling, and finally lying down and falling asleep. It was all Toni and I could do to walk again, but we managed to head back up the trail, crawl into the tent, our pulses still racing, but an overwhelming sense of exhaustion prevailing, and we fell asleep almost instantly, visions of daddies and daughters fucking drifting through our dreams.
