"Whoa... I don't know about this..." Kevin protested.
Kevin and his girlfriend Jessica were visiting his friends Mike and Nikki who'd just moved into a new house by the lake. It was a humid summer weekend, and after Mike grilled up some steaks on the deck overlooking the water, the four of them had decided to go for a swim.
Jessica insisted that she needed a shower before going swimming. Kevin didn't particularly understand the point of rinsing yourself off if you were just going to hop into the water, but he'd learned not to argue with his girlfriend. They'd been dating for almost six months. Kevin actually met Jessica through Mike and Nikki. He'd been friends with the married couple for years and at one of their parties Nikki had invited her coworker Jessica. Kevin had immediately fallen for the gorgeous, petite Asian woman and they'd been together ever since.
"Come on, it will be funny!" Nikki insisted, pushing Kevin back onto the bed.
Kevin had gone into the guest bedroom to change into his swim trunks. He'd already peeled his shirt off and begun to unbutton his jeans when Nikki had come barging in. She spoke in a hushed, hurried tone and had the giddy, excited look on her face that she always did when she was up to something. Nikki liked to play jokes on people and no one was more frequently targeted than her husband Mike. For the most part Kevin found her quirky sense of humor amusing, but at times she seemed to not understand what lines not to cross. He was beginning to think this was one of those times.
"Oh, come on, lighten up, Kev!" Nikki said teasingly, using the nickname she knew Kevin didn't like, "It will be hilarious. Look, I have the webcam set up at just the right angle to catch his reaction when he walks past the door. All you've got to do is sit there and act like you're enjoying yourself."
It was all beginning to make more sense. Since he'd gotten there over an hour ago, it seemed that Nikki was being particularly flirtatious with Kevin. He hadn't thought much of it at first, her hand lingering on his as she passed him a beer, batting her eyelashes and laughing just a bit too long when he cracked a joke. She'd been planning this since she invited them, Kevin guessed.
Nikki's plan was to have Kevin sit on the edge of the bed. She would get on her knees in front of him and pretend to give him a blowjob. The webcam on the computer would capture Mike's reaction when he walked past the open door and saw what appeared to be his wife sucking on his friend's cock. It was typical of her kind of risky, questionable humor.
Nikki took Kevin's reluctant silence as consent and moved quickly. It wouldn't take Mike long to change in the master bedroom and she wanted to be in position. Kevin's pants were already unbuckled, so Nikki tugged them down around his ankles. His striped boxers were tugged down a little as well, far enough that a tuft of pubic hair peeked out over the elastic waistband. Kevin quickly pulled the boxers back up, opening his mouth to protest. He lost his train of thought however as Nikki peeled off her shirt.
The tight shirt dragged Nikki's large breasts up as she pulled it over her head so they fell free, bouncing generously. Nikki had indeed planned this joke out far in advance. So much so that before the other couple had arrived she changed out of her bra and put two pieces of black tape over each nipple in an X. Kevin's eyes watched Nikki's perky tits jiggle as she laughed in anticipation of the joke's effect on her husband.
Kevin felt the blood rushing to his cock. He knew that Nikki was just doing this for a laugh, but still he was getting turned on. Nikki was a cute Latina a couple years shy of her thirtieth birthday. She had long flowing brunette hair with blonde highlights and full, puffy lips. Her tits were amazing. They were real and very big and round, like her ass, jiggling with every movement. Unrestrained by clothing, they swung freely, brushing against Kevin's bare thigh as she bent over and flipped the short skirt she was wearing up over her ass so that her husband would have a good view of her panties when he came by. Kevin noted that there was no sign of tan lines on her smooth, olive colored skin.
"Okay," Nikki whispered with one more hesitant look over her shoulder, "now we've gotta make this look as real as possible. So just close your eyes and pretend you're having a good time, maybe throw in a moan or two if you think you can keep a straight face."
With a final wink, Nikki licked her lips and began bobbing her head up and down, lips parted as if taking Kevin's invisible cock into her mouth.

Mike was already changed into his swimming trunks, a towel thrown over his shoulder. The squeaking door on the master bedroom reminded him of something. They'd just moved in last week, and the previous owner was supposed to fix a couple things. One of which was the doors to the bedrooms, both were slightly warped, making it so that they would not lock properly. Apparently the contractors had not gotten to the doors, so he decided to take a quick little video on his phone to demonstrate. He opened and closed the door a couple times, showing the misalignment at the top and bottom before moving down the hall to the guest bedroom.
Mike rounded the corner and stopped short, shocked by what he saw. Ten feet from him his wife was on her knees, her round ass poking out behind her with her face in Kevin's lap. Her head was moving up and down as she sucked him off. Mike could hear the slurping noises she always made as she went down on him. Kevin's eyes were rolled back in his head, and he was leaning back on his elbows with his pants around his ankles.
Fire began to burn inside of Mike. He watched as his wife rubbed her pussy through the lace panties he'd bought her last valentine's day as she continued to slurp on his friend's cock. Instinct told him to run into the room and beat them both senseless, but he was frozen in fury as he watched. He didn't breathe for several seconds, finally storming off down the hallway without saying a word.
As he continued to walk down the hallway, his anger grew hotter and hotter. Nikki had been flirting with Kevin all afternoon. He thought she was just trying to get him jealous, which she'd been known to do from time to time. She thought it made the sex hotter when she got him all riled up. Now he started to suspect that Nikki and Kevin may have been having an affair. How long had it been going on? Did Jessica know?

Kevin could feel that his face was flushed. He was embarrassed, because his cock had begun to grow hard, starting to lift his boxers. He couldn't help it. Just the visual image of Nikki's full lips wrapped around an imaginary cock as her tits brushed up against his leg was turning him on more than he would have liked to admit and now she was making very convincing sucking sounds to augment the illusion. He leaned back on his arms and closed his eyes, unknowingly missing Mike who stood briefly in the doorway with his phone out. When he opened his eyes back up he and Nikki still thought Mike was still in the bedroom down the hall.

Jessica was in the shower that had access to the deck. It was a nice addition to have a shower that one could use before entering the house proper when coming back from a dip in the lake or the hot tub which was out on the deck.
She had just stepped into the warm spray of water when she heard the door open. Instinctively, Jessica threw an arm over her b-cup breasts and her other hand between her thighs to cover herself as she spun to see a wide-eyed Mike. His face was the picture of unbridled rage.
"What's wrong?" Jessica said, keeping herself covered with her hands.
Mike opened his mouth as if he was going to say something, but no words came out. Instead he exhaled heavily through clenched teeth. He punched a couple buttons on the phone he was holding with a white knuckled grip, turning it so that Jessica could see the video.
Still confused, and uncomfortable at being accosted by her host while she was nude, she leaned closer to see the image. It was just a door opening and closing followed by the image of Nikki on her knees blowing her boyfriend.
Jessica's mouth dropped open, and she held a hand in front of her face in disbelief as she watched her friend and coworker take her boyfriend's cock in her mouth as she rubbed her own pussy.
"What... where.... where did you get this?" Jessica asked, still in shock as the video ended.
