Splashing water at each other!

I looked at the three people enjoying the cool water. My wife Anne, my sister Kristin, and her new found boyfriend Patrick. They were knee deep in the water, waddling about and occasionally splashing water at each other jokingly while chatting and smiling. They truly looked like they were enjoying themselves.

My gaze wandered to my wife Anne. She was wearing a white t-shirt that was mostly soaked from all that splashing so it was translucent and clinging onto her body. Her slim and alluring body underneath and the navy blue bikini top were clearly displayed. The t-shirt ended at her hips and her creamy white thighs and a hint of her supple butt cheeks that were peaking out from her bikini bottom could be seen below. As she engaged my sister in a splashing competition, I noticed Patrick hanging back behind her and checking her perky ass out. From the tent in his shorts, it was obvious that he was enjoying whatever he was seeing up close.

"Anne's really hot!" I heard Alvin suddenly say from beside me. I turned to him, a little surprised at how direct he was, only to find him still staring ahead. I was about to say something when Shandy smacked him on the back of his head jokingly, breaking him out from his admiring stupor.

"Huh? Heheh.. sorry bro. I think I might have drank too much of that cocktail." Alvin apologized embarrassingly. I chuckled back in response as my eyes went to the empty glasses that laid around us. I wondered how good the cocktails must have been for them to finish so many glasses.

Suddenly, a shrill scream from the water followed by loud giggling drew my attention back. My eyes widened when I saw Patrick hugging my wife from behind, his arms around her holding her in place as my sister bombarded them with water from the lake continuously. The two of them were shamelessly ganging up on Anne. I was about to step in when I noticed that my wife was still laughing at the situation even though she was struggling to break free from Patrick's tight hug. I held back a little, wondering if I was simply being too paranoid when they were simply having fun.

It was then that I noticed how Patrick's arms that were wrapped around my wife was pushed up against her breasts. One of his hands even slipped underneath Anne's t-shirt and clearly started grabbing her breast. I watched my wife wriggling about in his arms, her ass continuously rubbing and pushing up against Patrick's crotch as she tried to escape from his hug. The huge erection Patrick was having in his shorts was clearly seen by me even from this distance, and I thought that it was impossible that Anne would not notice or even feel it when she's rubbing her ass against it over and over again. Was she doing it on purpose? It did not even look like she was truly trying to get away from him.

I was about to step up and put a stop to their horsing around when Anne suddenly turned around to face Patrick and pushed him away from her. I was gloating inwardly in glee and praising my wife when I saw a piece of navy blue fabric flying away from Patrick's flailing arms and into the lake. At the same time, both my wife and Patrick fell into the water with a loud splash.

It took the both of them a few seconds to resurface. Since they did not go too far away from the shore, they were not at a deep part. Patrick seemed to be sitting on the lakebed, the water coming up to his shoulders when he sat down. What made my eyes grew wider was the fact that my wife Anne was right in front of him, still facing him with the water also coming up to her breasts. She seemed to be seated a little higher, so it was obvious that she was straddling Patrick right now! My sister waddled up to them to ask if they were alright, and both Anne and Patrick told her that they were okay as the wiped the water away from their faces.

I knitted my brows when I saw that the both of them did not have the intention of moving at all. Anne was still sitting on Patrick's lap under water, her legs spread apart and on either side of him. My mind suddenly recalled the navy blue piece of fabric that was tossed deep into the lake earlier. Could it be?

I gazed at Anne's chest and could clearly see the navy blue bikini top still underneath her white t-shirt. So that means that what I saw flying away earlier was her bottoms? I looked at Anne's face and immediately noticed her flushed and embarrassed expression. Patrick in the meantime, had a mischievous grin on his face.

"Alright. You can give it back to me now." I heard my wife say as she slapped Patrick playfully on his chest.

"What are you talking about? Give you what?" Patrick said as he raised both his hands in the air above the water, the smile on his face getting bigger with each passing second.

"What are you two talking about?" my sister said with a confused look on her face as she stood beside them. She must not have seen Patrick throwing the piece of fabric away in the chaos. I took a brief moment to admire my sister's young but attractive body inside the one-piece swimsuit. Her young but perky breasts and slender waistline leading to her trim and fit legs. My attention was quickly drawn back to my wife though as she started reaching under the water seemingly to tickle Patrick's waist.

"Your boyfriend took something of mine and he doesn't want to return it!" Anne said as she continued to tickle Patrick underwater.

"I didn't take anything of yours! Search me if you want!" Patrick exclaimed as he struggled to push my wife's hands away from his body. I knitted my brows when I saw how intimate the two of them were acting. What was Anne's thinking behaving like this? She is usually a little more proper. Was it the fact that we were at a holiday right now that made her less careful?

"Stop lying! Ahh! I know! You must have hidden it inside your shorts!" Anne suddenly exclaimed as both her hands reached down into the space between the both of them. I saw her hands fumbling around a little bit while Patrick simply watched her with an amused look and no intention to stop her. Suddenly, Anne jerked her head back and stared at Patrick with a shocked expression. At the same time, a wide grin broke out on Patrick's face as he gazed back into my wife's eyes, his eyebrows jumping teasingly at her.

"So? Did you find what you were looking for?" Patrick said with a grin on his face. Anne remained silent but I noticed that her hands had started moving back and forth under the water ever so slightly in the small space between her and Patrick! It did not take a genius to guess what her hands were grabbing under the water right now! I looked back at my sister and saw that she had waddled away from my wife and Patrick while looking like she was searching for something in the water. That must have given Patrick the courage to think that he could play with my wife a little bit. I saw Anne suddenly getting pulled closer to Patrick and he took the chance to practically bury his face in between my wife's breasts! In that brief moment, I noticed Anne's body getting lifted up slightly before she abruptly fell back down onto Patrick's lap again. When that happened, I saw Anne tilt her head back with her eyes closed and her mouth open slightly. She looked like she wanted to cry out but was trying hard to hold back her voice for some reason.

I was momentarily stunned by the series of events that happened so rapidly all of a sudden. Did Patrick just slip his cock into my wife just now? Why is Anne making the same kind of expression she has when she is having sex with me? I sat mindlessly on the beach while trying to make sense of what I was feeling when I saw what seemed to be Anne bouncing up and down ever so slightly on Patrick's lap.

"It can't be... right? It must be because of the waves that is causing the illusion of Anne bouncing up and down right?"

I was still in denial when I suddenly hear Alvin say from beside me.

"Heheh.. hey Jake, doesn't it look like Anne is riding that guy in the water right now?"

I kept my eyes on Anne and Patrick as I was too afraid to turn to look at Alvin. I was scared that he would notice the complex emotions in my eyes right now. My mind blanked out as I stared at the woman I just married yesterday possibly having sex with my sister's boyfriend in the lake right in front of me. I heard a slapping sound next to me, probably given to Alvin by Shandy for saying what he said earlier. The edges of my mouth curled upwards slightly when I heard that. Shandy had always been sensitive to my feelings. I instantly felt a bit better, but it was quickly washed away by the various streams of emotions gushing through me again.

Just what was I feeling right now? Jealousy? Desire? Lust? Anger? Excitement?

All I could say was that, I was feeling all of that. The fact that I was having a raging boner in my shorts was prove that I was turned on right now! I cannot say that I am getting turned on by the fact that my wife was cheating on me. In fact, it cannot even be proven that they are fucking right now since everything is hidden under the water. Maybe they were simply sitting there and enjoying the gentle waves right now. Maybe it was all a misunderstanding or fantasy on my part. More importantly, I realised that maybe I was simply an extremely lust-driven man. I can get turned on very easily by the simplest of situations or the simplest of fantasies.

Suddenly, in the midst of my introspection, I heard a shout from the lake.
