"What's going on Mike?" asked Karen.
"What do you mean?" queried Mike, fairly sure he knew but hoping he could play dumb.
"You know damn well what I mean. Angela and Brendan vanished around that corner over there and then four of the boys went that-away, laughing, and a number of others, including you, started smirking. So talk."
Mike hastily ran what he knew of Karen through his mind, the big questions being was she prudish and was she a nasty gossip? He was quite sure that she wasn't a virgin and the way their relationship was developing he had hopes of taking her to bed very soon.
Karen waited, confident that Mike would talk to her sooner or later. He was considering something and she felt sure he would confide in her.
"You know Angela and Brendan are sleeping together?" Mike asked.
"Yes. Angela hasn't been too backward about hiding that information," laughed Karen. "According to her he's an artist in bed."
"I'll take her word for that," said Mike dryly. "Right now Brendan is taking her to a secluded little nook that he knows of, where he will proceed to strip of her bikini and demonstrate his art to her."
"That doesn't exactly surprise me, but it doesn't explain where the other boys went or why you and some of the others were laughing about it."
"Well," said Mike, "if you go that-away," indicating the direction the boys went, "you will find a couple of places that gives you an excellent view of Mike's secluded little nook."
Karen stared at him. "You mean that they're going to go and watch Angela and Brendan have sex, without them knowing," she said indignantly.
"I didn't say that, exactly" said Mike.
"You mean that Angela and Brendan do know and don't mind?" Karen asked incredulously.
"I didn't say that either," said Mike, starting to feel a little nervous about where this was going.
"Maybe you should tell me what you did say," demanded Karen. "Do Brendan and Angela know or not?"
"Well, yes and I don't know," returned Mike. He sighed. "Brendan knows about it but I don't know if Angela does."
"You mean that Brendan is going to fuck Angela while the boys watch and she may not know? Shouldn't someone tell her?"
"No. Generally, if any of the girls do find out they keep on pretending they don't know. If they know and don't want to be watched they just make sure they don't go there. If they get a secret thrill out of being seen then they'll let their boyfriend talk them into going there. And if they don't know then they act naturally, enjoy themselves and never know that they've been seen."
"Oh. You mean I have to keep my mouth shut about it," said Karen.
"If you would, please," said Mike. "We're all adults and it's just a bit of harmless fun really. The boys get a thrill being voyeurs and it gives some of the girls a chance to be an exhibitionist without anyone being able to point the finger and say you knew we were watching.
"Hey!" Karen was suddenly indignant. "Andy tried to talk me into going down there for some fun, just before we broke off. Does he know about it?"
"Yes," said Mike with a grin. "I believe he does. Did you go?"
"Fortunately, no," said Karen. "Like I said, I was in the early stages of breaking up with him." She looked at him. "Have you ever taken a girl down there?"
Mike shook his head. "No, and I wouldn't unless she knew. I wouldn't consider it fair to her. I have to admit I have watched others there a couple of times."
"Oh. Did you see anything interesting?" asked Karen curiously.
"A couple of times there's been a real exhibition put on," said Mike with a laugh. "Sometimes you can guess when a girl probably knows from the way she acts."
Karen blushed as she asked "Do you ever get any girls watching what goes on?"
Mike's smile had an evil tinge to it. "There is one spot that is reserved for girls. The boys are careful to keep away from it, because any girl seen there is obviously not going to take part in any future entertainment. Want to go and see if Brendan and Angela are performing?" he challenged.
Karen's blush deepened, "You're kidding, right?" She paused and looked at him, her blush deepening. "You're not kidding. I couldn't."
"Why not?"
"What if someone should see us?" she protested.
"We're just going for a walk. If you don't know when to stop you would never notice them. Come on. Let's go for a walk."
Mike headed up one of the paths leading away from the beach, drawing Karen reluctantly behind him. Half way up he diverted down another path that led up to the cliff face, and indicated a cave in the cliff. "Ever explored these caves?" he asked.
"No," said Karen, wondering what he was up to.
"Well come and take a look. They're quite well lit. There are a number of places where the sun shines in."
Karen followed him into the cave system, a bit suspicious of his intentions, but willing to give him the benefit of the doubt. As they wandered down the passage Mike indicated a couple of holes that gave an excellent view of the beach. At last, at a point where the tunnel turned and went deeper into the cliffs, he indicated another couple of peepholes. "Try one of those," he said.
Karen glanced through and gasped, staring harder. She was looking out at what had once been a cave that had collapsed, leaving a small circular area that was almost but not completely enclosed. She could see a narrow gap that evidently led back to the main beach. And in the middle of this little circle she could plainly see Angela, naked and on her hands and knees, laughing back at Brendan who was kneeling behind her.
Even as she stood and watched, she saw Brendan align himself with the offered bounty and thrust vigorously forward. She saw Angela raise her bottom up, joyfully meeting this cock that was driving into her. She knew she should look away, but found herself unable to tear her eyes away from what was talking place before her. Brendan was happily thrusting into Angela, while her bottom was bobbing up and down as she moved in time with him.
Brendan's hands reached forward and cupped Angela's breasts, and Karen could almost feel them, as though he were clutching her own breasts. "Wait a minute," she thought, startled. "I can feel that." Looking down she realised that Mike had slipped his hand under her bikini top and was cupping her breasts and playing with them, which was a lot more than she'd ever let him do before.
Not wanting to make a noise in case the couple outside heard, she reached up to draw Mike's hands away from her breasts, but found herself just clutching his hands as she watched Brendan continuing to plunge into Angela. She continued to watch, fascinated, as Brendan and Angela enjoyed each other. She barely noticed one of Mike's hands drop away from her breasts and slip down the front of her bikini pants and cup her mound, while pressing his erection firmly against her buttocks.
Mike continued to gently tease Karen, feeling her move restlessly against his hand, breathing hard as she continued to watch the action through the peephole. Seeing her preoccupied with the action outside while enjoying his caresses, he took the time to slip her bottoms down, watching with satisfaction as they dropped away.
Karen was aware that Mike was seducing her in time to the action that was taking place outside, but found she didn't care. His hand was invading her private parts now, rubbing her labia, moving her lips apart and darting his fingers inside to further tease her. She could feel his erection pressing hard against her, and while part of her was nervous a larger part wanted him to take her, now.
Mike felt Karen reach down and grasp his cock. She was bending over now, spreading her legs, while at the same time trying to watch the action taking place outside the cave. Mike felt Karen pushing his cock down away from her buttocks and between her legs, trying to steer it into the folds there so that it could bring her relief. He didn't try to help her, sensing that she wanted to do this herself, and heard her gasp of relief as she managed to direct the head of his cock between her lips.
Now that he had the go ahead Mike drove firmly up into Karen, feeling her vagina stretch and swell around him, welcoming him into her. With both his hands now grasping and playing with her breasts, Mike drove home with a vengeance, hammering his cock into the eager pussy that was thrusting happily back to receive him.
Brendan and Angela were hitting an orgasm together, Karen noticed, relieved that the action outside was effectively over, letting her concentrate on the lusty fuck that she was enjoying. Not realising how tense the voyeurism had made her, she now relaxed that little bit, pressing eagerly against Mike's cock, feeling it sliding in and out of her, stirring up all sorts of delicious feelings.
Mike could tell that he now had one hundred percent of Karen's attention. He could feel her eagerness for completion as she writhed under his hands and pressed frantically against his cock. He drove into her, harder and faster, eager for his own climax and happy to feel her reaching for her own. He heard her shocked gasp as her climax hit her, and was relieved that his own came at almost the same time. Heavy final thrusts pumped his seed out and into her willing body, before both of them relaxed, leaning heavily against the cave wall.
Karen was the first to speak. "Oh my god," she moaned. "I can't believe I just did that. First of all I spied on Angela and Brendan, and then I let you take me. You had no right to just take me like that you know."
Mike was no fool. If blame was being assigned he was quite willing to accept it. With a bit of luck he'd shortly be in a position to earn more blame.
"I'm sorry, Karen," he said, apology patent in his voice. "I just found you irresistible."
"I suppose I'm partly to blame," mumbled Karen. "I didn't exactly fight you off."
"Not unless you call grabbing my cock and jumping on it, fighting," thought Mike, but had more sense than to say it.
"We'd better be heading back to the beach ourselves," he told her. "It probably won't hurt if we go in for a quick swim on the way back, either."
Karen grinned at him. "That might be a good idea. A better one would be to help find my bikini bottom. It seems to have gone astray."
Disporting themselves in the water later, Mike re-opened the subject of the voyeurism. "So what did you think of a little voyeurism?" he casually asked Karen.
Karen appeared to consider the question. "I'd love to know if Angela knew that she was being watched," she said.
Mike laughed. "I suspect she did. She definitely positioned herself so that she could show off everything she had to any watchers in the caves."
