Chapter 4: Taking a Dip and a Dick

My attention was on them so much that I almost smacked another boat so I figured it was time to make the day a bit more interesting. Nodding back to the two in the back, I told Sam that it looked like they weren’t too interested in tubing anymore so would he mind if I pulled over somewhere? Needless to say Sam didn’t mind so I found a small cove to pull into. It wasn’t exactly a private beach but it would do. With the boat anchored we could swim on the shore side of the boat without drawing too much attention to ourselves, not to mention anything else we might do...

“Cool Kelly!” Kristen exclaimed once we had the boat anchored in place. “Now THIS is more like it!”

With that she pulled her hand out of Mike’s suit, quickly stripped off her bikini and jumped in to the water, initiating a skinny dipping party. Mike rapidly followed suit and I look at Sam who just shrugged his shoulders and started pulling his own pants down. As I stripped I finally got a good view of what had been hiding all day under his shorts and was truly impressed. Although it was still pretty soft I estimated his cock was probably in the seven to eight inch range making it better than average in that category and it was surrounded by a thick bunch of dark pubic hair which, as anybody who knows me will attest, is a definite positive for me. He didn’t seem shy about me seeing him and as he turned to jump in I couldn’t help but lick my lips at the tight white ass in front of me.

I was the last to hit the water and then we were all in. The water was fairly shallow and the bottom was sandy which was a relief for me. I hate mud bottoms as they always make me feel like there is something slithering around below me. In this case I was able to keep my head above water but the rest of me was submerged. The water was surprisingly clear for a Pennsylvania lake but still not quite enough for anyone to see more than my boobs and the same went for Kristen. I could see Mike and Sam’s chests but that was about it.

Mike swam over to Kristen and she squealed with a big smile on her face as his hands disappeared under the water and touched her only lord knows where. He was behind her with his arms wrapped around her lower body, pulling her against him. I had little doubt that he was getting pretty hard and that she was feeling something poking her in the back by now.

Both Sam and I just swam around for the time being, watching the show developing in front of us. Mike maneuvered Kristen back over to the stern of the boat where the there was a platform at water level for getting in and out of the boat. Kristen grabbed the wood decking for support and I saw Mike reach down between them. He must have been guiding his cock in her as before long he was humping her ass and obviously fucking her, a fact that was soon established by her moans and cries.

“Oh yes Mike, fuck me harder!” my cousin the little slut begged.

I tried to imagine what was happening under the water and felt myself getting wetter than what was being caused by the lake water against my pussy. I turned to Sam who was now right next to me.

“What do you think Sam, ever watched your brother fuck a girl before?” I asked.

For the first time so far today my assessment proved to be wrong. I had just assumed that based on their comfort with stripping in front of each other that they had probably had sex together as well - not with each other mind you but with other girls or maybe even sharing a girl. Obviously I was surprised by his response.

“Actually no Kelly,” he said, “Can’t say I have ever seen Mike like this before. Actually, I’ve never watched a guy fucking a girl for real. I have to admit though, it’s pretty hot to watch!”

The way Kristen was pushing back into Mike with each thrust and the cry she would let out each time he drilled her I had to agree with him. Needless to say Kristen was no virgin so when she was looking this hot a guy must be doing quite a number on her.

I was quickly growing tired of watching though, especially when I had a hunk like Sam naked in the water next to me! It seemed like there was some definite cock going to waste!

I turned to Sam and in as seductive of a voice as I knew how to make, said, “So tell me Sam, who fucks better - you or Mike?”

Sam grinned and turned to me as well. “Well, I don’t want to sound egotistical but my little brother may be good, he could still learn a few things from his big brother.”

I reached down and grabbed his cock and once again found myself wrong - twice in one day! But if you have to be wrong, this was definitely the way to be. I had judged him to be above average in cock size but he was evidently the type that started out smaller but grew a LOT when he got erect. My hand barely fit around the monster I was holding and though I couldn’t see it through the murky water, I had a damn good idea of what it must look like. I normally like a more average sized cock because it is easier to suck but from the looks of things today was going to dominated by fucking so a big cock was more than welcome.

“Wow Sam!” I couldn’t help but gush, “I guess you weren’t just being chronological when you called yourself his ‘big’ brother.”

Sam smiled and looked just a little bit satisfied with himself but who could blame him? He had to know what he was blessed with and I am sure I wasn’t the first girl to be wide-eyed when she realized what was waiting for her. My pussy throbbed as I stroked his giant cock and I knew I had to have him in me sooner than later so I pulled him along by his dick until I was side-by-side with Kristen who was still being fucked hard by Mike. Actually only a couple of minutes had passed since they had started, it guess it just seemed longer due to my preoccupation with such a big male specimen.

“Hey girl, mind if I join in?” I asked her.

“Oh my god Kelly,” she gasped, “God I love this! I love fucking in the water!!”

Usually I’m a big fan of cuddling and sometimes I can spend the entire night doing it without even fucking but this wasn’t one of those times. At this moment though I just wanted to be fucked and fucked hard so there was going to be no foreplay, kissing or anything. I just wanted that big cock in me as fast as I could get it in! I could feel Sam reaching between my bare legs and then he started pushing his finger deep inside of me. I gasped as he fucked me with his finger while his other hand reached around and started to play with my clit.

He must have wanted to fuck my pussy as bad as it wanted to be fucked because the next thing I knew I could feel the head of his cock pressing up against my ass. He squatted down to allow it to move down the crack of my butt and then it slipped down between my legs. I could feel it slide under me as he drew it back until it was properly positioned just outside my waiting pussy hole. For just a second though he hesitated, as if unsure he should be going this fast. It was less than ten minutes since we left the shore and here he was already nude in the water with a new girl and he was about to fuck her already!

“Do it Sam,” I begged, “Fuck me ... damn it don’t wait any longer, just fuck me with your great big cock!”

Sam obliged and I immediately felt the pressure from his cock head increase as his fingers spread my pussy lips apart to make way for him. I groaned from a mixture of pleasure and then pain as it felt like I was going to be split in two as his cock head forced its way into me. My God he was huge! It had been a long time since I had a cock anywhere near this size in me. The last time was around Thanksgiving last year at a frat party and actually I was beginning to think Sam’s was even bigger than that one which would make Sam the biggest cock I had had (so far at least!). It felt like he was filling my pussy and so far only the head was in me!

“Oh ... my ... god!!!” I exclaimed as he shoved it roughly further up into me. It was like a huge log was inside of me, actually forcing my legs apart like I was having a baby except this monster was going IN instead of OUT! Each time I thought I had all I could take in me he shoved it in me deeper, pushing yet another inch of his engorged penis into my welcoming pussy.
