Chapter 6: David Does Brenda on the Lake

The lake was only a few blocks away so we walked along the side of the road and reached the docks in just a few minutes. There were several guys struggling to put their boat in the water at the ramp. I smiled wickedly at them as they turned to stare at the two of us walking by. Another time and I might have hung around a bit and teased them but we had other things on our mind.

When we got down to where her dad kept their pontoon boat tied up we saw it was still gone and there was no sign of her dad or brother. Fortunately the section of lake in this area was relatively narrow and Brenda knew where her dad liked to fish so we walked along the bank until finally we spotted them. They were quite a ways away but after shouting for a minute or so they finally heard us and her brother waved. The fishing must not have been very good because in a few minutes they had pulled up anchor and were heading back to the docks as there was no place along the shoreline for them to get close enough to pick us up.

Brenda and I ran back to the dock and waited for them anxiously. It wasn’t long before they showed up, going as fast as the little motor would push them. We helped them tie up the boat and Brenda hugged her dad and brother. David looked at me and winked. I looked at his crotch and memories of how his cock had tasted just a few hours ago came flooding back in my mind and my pussy tingled as if to tell me it wanted his cock as well. From the way he was looking at me I had an idea he wouldn’t mind satisfying that wish!

Brenda asked her dad if we could go back out fishing with them. He just shook his head and complained the fish weren’t biting and that he had had enough for one day. No sooner had he finished than David volunteered to take us out if we really wanted to. Brenda’s dad just shrugged his shoulders and said something about “a stupid waste of time” but then he had no idea what we would be fishing for. I had a feeling we weren’t going to be disappointed with our catch! Her dad went up to the parking lot with his gear while the three of us pushed off and headed back out to the middle of the lake.

As we motored down the lake I looked around me. Compared to my parents’ ski boat their pontoon boat wasn’t all that fancy but it was clean and comfortable. The front end was surrounded by well-worn padded seats with a small swinging door at the bow that opened to a small “porch” up front. In back there was an overhead awning that covered about a third of the pontoon boat. A pedestal-like thing had the steering wheel and throttle on it and the entire floor was covered in tacky green indoor-outdoor carpeting.

David was at the wheel and he steered us out to take a cruise around the lake. Brenda and I each took one side of the front end and stretched out on the cushions. It was still early in May but the sun was out more than ever and it was a perfect day so far as I was concerned.

I stretched out my legs, allowing my shorts to work their way up my crotch and over my ass to expose as much of my legs and butt as possible. Brenda was doing the same and she looked positively sexy as she leaned on one elbow with her boobs hanging down and her nipples poking through. David was watching us more than he was the lake and while we pretended not to notice, we both were doing our best to give him something to look at.

The boat wasn’t exactly fast but eventually we made it to a bend in the lake where an inlet led to a small cove. There wasn’t another boat in sight as it was still early in the season and not many people were on the lake period. Once we were far enough in to where it was hard to see the lake, David stopped the engine and dropped a concrete anchor overboard with a loud splash. It was a good thing we weren’t planning to do any real fishing as it must have scared every living creature for a hundred yards!

“Are you sure we can’t do swimming?” I asked, hoping that perhaps in the privacy of the cover we could do it even though it was against the rules...

Brenda shook her head at me and answered, “Well, first of all, if you thought the pool was cold, this the water is FREEZING and second, it’s not too deep here and lord only knows what’s down there when you jump in!”

I took a second look and realized what she meant. You couldn’t see more than a few inches below the water and along the bank was lots of weeds and the whole place in general may have been nice for fish but definitely not my idea of a swimming hole.

“Well, if we can’t swim then what do we do out here in the middle of nowhere?” I asked in a naive tone. It was obvious to us all what was on our minds - why else would we be here in the first place after all? Still, it was fun to play around and pretend we were on an innocent little cruise. Judging by the looks that Brenda and her brother were exchanging, I had a feeling the game was going to get a lot more serious pretty quick!

“So David, are you just going to stand there staring like an eighth grade boy peeking into the girl’s locker room or what?” Brenda teased her brother.

“Oh? ... is there something on your mind little sister?” David teased right back at her. He made a few steps closer in our direction and gave her a good, long look up and down her sexy freckled body.

Brenda turned more on her side and pulled her right leg up and put her bare foot on her upper leg which had the effect of spreading her crotch apart and pulling her already tight shorts even tighter up into her crotch. She wasn’t wearing any panties - that was obvious as the thin strip of material pulled up into her pussy slit and you could see the outer lips of her pussy poking out each side. It had the desired effect on David as he licked his lips and I saw that his shorts weren’t as flat as they were before!

As for me, I was getting tuned on just watching the little tit-for-tat that was taking place between this brother and sister pair.

“Hmmmmmm, maybe a little lower,” Brenda cooed to him as she took her right hand and cupped her crotch with it, pulling upwards and then rubbing herself. “See anything you want?”

David moved over until he was standing next to her head. Without further ado he simply unbuckled his pants and unzipped them. Pushing his underwear down, he pulled out his cock, which was about half-erect by now, and started stroking it right in front of her. I had to flip over to my other side to keep an eye on what was happening - I didn’t want to miss any of this, that’s for sure!

“You know, I hate to say this about my own sister, but you are one fucking slut Brenda,” David said with a grin, “Not that THAT’S bad!”

“Well, I may be that but what do you call a big brother who pulls out of his dick right in front of his little sister?” Brenda responded softly, her eyes fixed on his cock as he slowly stroked it right in front of her face.

“I don’t know but why don’t you just suck my dick and if you’re lucky, maybe I’ll fuck you,” he said with a smug grin on his face...

Brenda rubbed her pussy for him and replied, “Well, I think it’s more like if YOU’RE lucky you can have a piece of this pussy.” She unsnapped her shorts and pulled down the zipper, opening the flaps and then pushing her hand down inside where she started playing with herself again for him.

“Mmmmmmm, this feels soooooo good,” she sighed, “God I love touching me!” Then Brenda pulled her hand from her pussy, licked her finger suggestively, and then reached out for his hardened cock. “Alright, come here ... I want your cock in my mouth.”

She took him in her hand and started to slowly stroke him as he reached down and pulled her head up towards his crotch. He grabbed a thick handful of her long red hair and used it to hold her head close as she opened her mouth, her tongue extended as she waited impatiently for a taste of his cock. David moved forward just enough to slip his cock into her open mouth and then she closed her lips down around it. I watched intently as she started to slowly suck it, just the head at first, like he had put a popsicle or sucker in her mouth.
