Christian, Zach and Penny lay on the blanket for about half an hour, soaking up the sun and talking about their past summer jobs and experiences.
"I don't know about you guys," Penny began. "But all of that fucking and cumming has made me pretty hungry. Why don't we head to the camp to get cleaned up and have some food?"
The guys agreed and the trio started to get ready to leave. They decided to take a quick swim in the lake to wash the cum and saliva and lube off of their various parts. As Penny walked towards the lake both guys felt their cocks twitch as they saw cum oozing out of both of her holes, ultimately leading to a cum trail running down her inner thighs.
Penny noticed that she wasn't being followed so she looked over her shoulder before entering the water and asked: "Do you like what you see? Do you like seeing your sperm seep out of my fuck holes?"
"Yes," they both said in unison.
"You definitely wear our cum well," Zach said with a smile.
Penny smiled back and then dove into the water. The three of them swam for a few minutes and then packed up Penny's camping gear before heading back to camp. Upon arriving at camp Penny stashed her things in one of the female cabins ("I like you guys but we just met...and a girl needs her space!"). As Penny unpacked, Christian and Zach scrounged up some dinner and the three of them ate a good sized supper. By the time they had finished it was getting to be early evening and Penny announced that she was going to take a shower and then go to bed so she could enjoy not sleeping on the ground.
"Can we keep you company?" Christian asked.
"I was hoping you would," Penny replied, smiling. "After all, I already know that the boys' shower is usable."
Still naked from their earlier exploits, the three of them walked to the communal-style showers and turned three of the shower heads on. Despite having cooled off in the lake earlier, the clean water felt good after spending a lot of time in the sun. With her eyes closed, Penny let out a satisfied purr as both guys watched her beautiful body under the stream of water. After a minute or so, Penny cursed.
"Shit," she said. "I forgot to pee before we got in here. I really hate to leave this glorious shower...I'll be right back."
As she began to walk past Christian, he gently reached for her arm to stop her.
"You can pee in here, Penny," he said. "We don't care, right Zach?"
"It's cool with me," Zach agreed.
"Okay," Penny said, smiling. "Some boys - and girls - seem to find it gross for someone to pee in front of them. But if you guys don't care that's perfect!"
With that, she went back under her shower, purred again and spread her legs slightly. She then pulled up on the skin above her pubic hair line and a stream of light yellow urine began to intermingle with the water coming out of the shower head.
"Ah, that's so much better," Penny said as the stream finished. "Do you two have any soap?"
"We do," Christian said after a moment. "But there's an issue with it."
"Oh?"
"It can only be handled by Zach and me - girls named Penny simply aren't allowed to touch it."
"Wow, that's pretty weird," Penny said with mock seriousness in her voice.
"Well, it makes perfect sense to me," Christian retorted. "How about you, Zach - logical?"
"Perfectly," he said with a smile.
"Well, I guess that would be okay," Penny began. "I suppose with us being here all alone and there being two of you and one of me I couldn't really stop you even if I wanted to, right?"
Zach and Christian looked at each other and then looked at Penny, a puzzled expression crossing their features.
"We don't want you to feel..." Christian began.
"I mean, that wouldn't necessarily be a bad thing," Penny interrupted. "Some girls are into that kind of stuff. You know, being forced to do certain things against their will..."
Christian and Zach looked more confused than ever.
"I'll give you and example," Penny explained. "Let's say there's this girl named...Wenny. And she gets off on being forced to do certain sexual things by guys or girls that she trusts. And if those guys or girls ever started to do something she really didn't want to do she would say a safe word like "rabbit". And she'd like things to be pretty rough. And that game could start now."
With that Penny turned away from the guys, closed her eyes and put her face under the water, purring softly again.
Christian and Zach looked at each other, looked at their three-quarter mast cocks, and smiled and nodded.
Christian walked up behind Penny and started to soap up her smooth, toned back with his bar of soap. At his touch, Penny let out a startled gasp and leaped forward a step and turned around, covering her big tits and bush with her hands.
"Hey, what do you think you're doing?" Penny asked, a tone of disapproval in her voice. "You shouldn't be in here while I'm showering."
"Relax," Christian replied with a smile. "I just thought you could use some help getting clean. You look like you're a pretty dirty girl."
"I'm not a dirty girl," Penny replied. "I'm a good girl and I don't let strange boys touch me while I'm showering. I want you to leave me alone right now or I'll call for help."
"But we're here to help," Zach cut in stepping behind Penny so she was now between the two guys. "Christian's right - you do look like a dirty girl. We just want to help get you cleaned up. Besides, there's really nothing you can do to stop us."
With that Zach grasped both of Penny's arms from behind, firmly and not too gently. Penny let out a surprised shout but both boys saw her tremble a bit as well, belying the fact that she was getting very turned on. Christian advanced towards her and began soaping up her chest and abdomen and legs. Once they got a good lather he put the soap down and used his hands to massage the soap into her perky tits while playing with her raging hard nipples.
"Stop that," Penny said, keeping her voice as indignant as possible while moaning in pleasure. "I want you to stop now. I'm a nice girl and I don't let boys touch me like this."
"You love it," Zach said. "You're look like a nice girl but we know you like having your perky tits played with."
Zach let go of one of Penny's arms so he could get in on the groping fun, too; however when he did she pulled away as if to escape. "No you don't", Zach said and yanked her back toward him. Penny let out a yelp and Zach reached his left hand in front of her body and gently but firmly grabbed her throat.
"Now listen," Zach said into her ear. "You're going to do what we say or things are going to get unpleasant, alright? We just want to play with your body for a little bit. You're sexy as fuck and you've given me and Christian these raging erections by looking like a hot little slut. Now are you going to behave?"
"Yes," Penny said. "I'll do what you say."
"Good," Zach replied, keeping his hand around her throat for effect. "Now let's see what you have down here..."
Zach snaked his other hand down Penny's body until her found the curve of her perfect ass. He grabbed each cheek roughly and then proceeded to run his soapy fingers along her ass crack, eliciting a moan for his efforts. Meanwhile, Christian had moved down as well and was massaging Penny's clit, slowly bringing her to orgasm.
"I think she likes it," Christian said. "She's wet as hell."
"I don't like it," Penny moaned. "I can't believe you're doing this to me. I'm just glad you're not treating me like a dirty slut or hurting me at all."
