Chapter 7: My Turn With David

My pussy was so wet at this point that I couldn’t stand just being a spectator any more. I stood up and moved across the boat, kneeling next to Brenda and taking the same position she was in. My halter top fell open and my boobs hung free as my bare ass faced David, serving as an open invitation. I wiggled it for him and licked my lips seductively for him to see.

“Damn, looks like somebody wants a piece of this cock for herself,” David said.

“My turn,” I responded, “I wanna be fucked too.”

David was looking at my ass and the pussy that was his for the taking while he continued to fuck Brenda. Then he reached over with his left hand and grabbed my ass, squeezing each cheek and spanking me playfully. I wiggled it again for him and his hand worked its way between my legs and he pushed his middle finger up my pussy.

“Damn, I’ll say somebody wants some cock!” he laughed out loud, “Shit, that’s what I call a wet pussy!”

David quickly pulled out of Brenda, eliciting a moan from her as her pussy was suddenly empty and then there was another moan, this time from me as he took a step sideways and quickly thrust himself into me. Now THAT was much better! I mimicked Brenda’s previous actions and rocked on his cock as he stood there, basically letting me fuck his cock. With him all the way in I held myself in position, rotating my ass in a circular motion to rub his cock all around inside of me.

“Oh yea, that’s nice,” David groaned, “God you’re so damn tight!” After a bit he pulled back out of me and returned to Brenda’s pussy. Back and forth he went, alternating between the two of us every dozen strokes or so. I looked over at Brenda who was looking at me, a broad grin on her face as we took turns receiving his cock. She winked at me and I knew she had an idea so I winked back to signal I was OK with anything she wanted. The next time he pulled out of her she quickly turned around and pushed him backwards before he could start fucking me again...

“Have a seat big brother,” she commanded.

David sat back on the edge of the opposite cushion where I had been laying before. His hard cock was wet with our pussy juices and was sticking up in the air like a missile ready to launch. The hair in his crotch was matted down with our wetness, exposing even more of his cock for us to see.

Brenda pushed him back further onto the seat and then straddled him, placing her knees on each side of him, facing him such that her large boobs were hanging in front of his face. She lowered herself down as she grabbed her brother’s cock and guided it into her pussy yet again. Once it found the mark she dropped quickly down onto it until she was sitting firmly on his lap. She didn’t stay there long, though, as she started bouncing on his cock like she was riding a horse at a full gallop. David pulled her tank up to expose her large breasts which were bouncing even more in front of him and buried his face between them, letting her boobs rub against his face as she fucked herself on his cock.

As for me, once again I took on the role of spectator as I just sat back and enjoyed the show, playing with myself casually as I watched the two siblings enjoy one another. They were both good looking and it would have been hot to watch them fuck in any case but once again, knowing they were brother and sister made it something special for me.

Once again, as great as it was to watch them, how long could any reasonable person expect me just to sit back and watch them have all the fun? I understand that sex can be a great spectator sport but I prefer to be the one people are watching! I got up and stepped behind Brenda and tapped her on the shoulder, like I was on the dance floor and cutting in. She paused her bouncing and settled down on her brother’s cock. Even so, I noticed she was still squirming a little bit to keep him moving in her. She looked over her shoulder at me and grinned.

“Something you wanted Kelly?” she asked innocently as if we were all just hanging around doing nothing.

“You know damn well what I want,” I replied, smacking her bottom to make my point. “Quit hogging your brother’s cock!”

Brenda made an overly dramatic sigh and kissed David before lifting herself off and dismounting him. She stood to the side and waved her hand at him with a flourish saying, “Here you go ... all yours Kelly!”

With a clear shot at his cock, I turned around and backed into David. He scooted forward on the cushion so his ass was barely on the seat and he spread his legs so I could get between them. With my legs together it kept my pussy all the tighter but as wet as I was he had no problem entering me as I lowered myself down onto him. He reached around me and grabbed my boobs with both hands like handles as I rode him.

Brenda left her tank pulled up so her boobs remained exposed. It was all she had on as she stood in front of me and rubbed her boobs together as she watched me being fucked by her brother.

Just then we all heard a loud noise like a boat motor and Brenda quickly pulled down her tank and sat on the cushion next to us. I sat still, not sure whether I should get off David’s lap or stay where I was. The railing and seat back cushions would hide us from anyone seeing what was going on, at least so far as they were not right on top of us, so it seemed the best thing to do was to just act like nothing was going on. That sounds easier than it was given I could feel David’s hard cock throbbing in me!

About thirty seconds later we saw a large pontoon boat go by. It was out in the middle of the lake going full speed towards some destination. We waved at them and they waved back, not really paying a whole lot of attention to us. I just couldn’t help but squirm a bit - it’s hard to be still when a guy’s cock is inside of you! Fortunately, they had no interest in us and before long they were out of sight again and it was all quiet except for the muffled sound of their engine which gradually diminished away.

Brenda giggled a bit and said, “That was the people in that big house down the lake. I recognized their boat.”

“OH? In that case maybe we should have put on a show for them?” I offered.

“Oh fuck, that would be all we needed,” David replied.

His hands were on my hips now, pushing me in little circle like he was churning butter or something, making me rotate around on his dick. It felt good to feel his pubic hair smashed against my ass, rubbing against me like a soft brush as my ass swung around slowly.

“Well, I see it didn’t have any effect on you David,” I teased him.

I had my hands on my knees as I stirred his cock inside of me. Brenda was sitting next to us and now she opened her legs up and spread her pussy apart with both hands.

“OK David, that’s enough of her for now,” she said seductively, “It’s time to fuck this pussy again!”

I just rolled my eyes and pretended to be exasperated but it WAS her turn to be fair, even if I really didn’t WANT to be fair when it came to sharing his cock! I leaned forward which had the effect of lifting myself off his cock. I stood up and held my hand in my crotch, rubbing myself slowly as I watched David move over to where Brenda was exposing herself to him.

David pushed her back against the back seat cushion and leaned forward, holding himself off of her by grabbing the rail on each side of her head, suspending himself over her with his erect cock hovering over her stomach. He rubbed himself up and down her tight stomach, touching the tip of his dick to her boobs and then letting it slide down to below her belly button. Finally she grabbed it and pulled him down to where she was spreading her pussy open with her other hand and pulling the head of his cock against her pussy.
