Linda and I finish cleaning the house by late in the afternoon. By the time we finish, we're both filthy dirty and want a bath. The house has no bathtub or shower. To take a bath, you go down to the ocean and take a salt water bath in the ocean. Then you walk back up to the house and rinse with a small amount of fresh water. As on many small south seas islands, there's clean body or drinking water, take your choice. However, the climate on the island is such that bathing in the ocean isn't really such a hardship.

Linda tells me, "Larry, I have to climax at least once a day and I'm noisy when I climax."

Since we have lived in the same house, on and off, for over 18 years, I wonder why Linda finds it necessary to tell me about her need. However, that's a girl for you.

As Linda and I walk down to the ocean, we each wear the grubby house cleaning clothes and we each carry a towel. Linda carries a largish bucket, a clean toilet plunger, salt water soap and a bottle of detergent. I carry a fishing pole. We'll wash the clothes and ourselves in the ocean. We'll then walk back to the house and rinse ourselves and our clothes in fresh water. The more or less fresh rinse water will then be used to water our garden. Waste not, want not!

We get to the shore and I ask Linda, "Do you want to take either the left or right beach and I'll take the other?"

Linda looks at me with great impatience. She sighs, "Brother dear, we have something of a problem here. I damn well need a good hot fuck or two after a week on the road. If the little surfer girls were correct, you need the same thing. You need pussy, I got pussy. I need cock, you got cock. Now what's this shit about separate beaches?"

I stare back at Linda and ask, "Wanna fuck?"

Linda half turns, looks down, makes a show of biting her lip and says, "I thought you'd never ask, you smooth talking son of a bitch!" Eloquence is definitely not Linda's strong suit. Getting to the point is!

Linda and I find a good patch of damp, packed sand. Linda gets down on all fours, I mount her from behind and we do it doggy style.

I'm at my horny, pile-driving best and Linda wants to be raped, not just fucked. Mind you, she's willing to help with the rape, but just keep the hard cock coming until she climaxes!

I get in deep and a damn good thing! Linda wiggles like she's hanging from a tree. It's like two lions fucking and easily the best I ever had. (Actually, I doubt a male lion could have kept up the pace!)

My big, hard cock gets in deep.

Linda wiggles to make sure every part of her pussy and every part of my cock are getting fucked. If Linda's pussy was a business, it would be called, 'Internal Muscles R Us!'

We thrust back and forth. Linda has volleyball muscles and I have surfer muscles and we use 'em all! We keep up the hectic pace until we can feel each other getting to climax. I speed up from raping ape to supersonic and Linda speeds up from raped ape to gotta have it now!

I shoot my cum over several strokes and Linda milks me dry with her internal muscles.

After we finish, I pull out and lie beside Linda, who has collapsed on the sand. We stay there for a bit, lying on the packed sand. I then get up and give Linda my hand and help pull her up. There's a brief stroke of lust lightning as we stand face to face only a couple of feet apart. Then Linda steps back and says in a 'good girl' voice, "I hope you don't expect a kiss sir, you're my own goddamn brother for chrissakes!"

I ask politely, but with a leer, "Do you come here often?"

Linda vamps me and says, "As long as I come here, I come here, Big Boy!"

We then go about washing ourselves and our clothes in the ocean. Well, we put our dirty clothes in the bucket, pour in some ocean water and some detergent. I then work the toilet plunger agitator. The work necessary to move the clothes with the plunger is fairly hard and I do it all. Actually, I have to stop when the water in the bucket gets really dirty and Linda empties the bucket, rinses it out, fills it and then I agitate again.

We take our time and we're pretty well recovered from our fucking by the time we finish.

I have been looking for a place to fish and I think I see a good place a little further down the beach.

Linda steps up and asks, “What are you looking for?”

"I have been looking around for a fishing spot that should yield us some supper. However, I'm now looking at tits."

Linda wiggles her tits and slightly opens her pussy. She smirks, "Swap you a hot fuck for a share of your catch. I'd rather be a whore than a slut any day!"

Linda has found my weak spot and see if I care!

We do it again, doggy style on the damp sand (got to keep the sand out of Linda's pussy.) It 's as good as our first fuck and maybe better. We're both still horny after a week without sex. However, the desperate edge is off and we can enjoy the sensation instead of trying to fuck away a week's worth of horns in one fuck.

I get in deep and hard, but work slowly. Linda takes it all and wants it as badly as I do. We work slowly and it's like each thrust is a fuck all by itself. With the urgency of the first fuck gone, I not only feel the internal muscles of my sister working, I can also feel the muscles work in her torso as she gyrates like a woman possessed.

Okay, our second fuck is even better than the first and I want it to last a long time. However, I can feel Linda getting ready to climax and I join her for a second shattering, mutual climax. I don't pump as much cum in her the second time and Linda is able once again to milk me for all of my cum.

After we finish, I tell Linda, "We need to bring down a blanket or something next time, because I want to get your legs over my shoulders and try to ram my cock so far up your pussy that you can feel it in your throat! Also I want to get you into multiple-climax until you're my sex slave."

Linda tosses her head and says, "I might become a sex slave and then again, I might not. However, you'll have to earn it, if I'm going to be your sex slave!"

We wash ourselves again and Linda keeps away from me when she gets out of the water. She tells me, "The path back to the house is steep and I need to find out how much energy I need for the climb up the hill before I fuck it all away."

I tell my sister, "Take my stuff up the hill with you and I'll stay and try to catch some fish for supper."

Linda gathers up both of our clothes and asks me, "Do you want a towel?"

"Yeah, I'll need the towel to wrap around myself when I come back to the house."

Linda leaves me my towel.

She then poses nude and says, "I aint gonna wear no towel home, chicken! Nyah, na nyah, Na nyah, nah!"

I reply, "Then you better think of something clever to tell Laura."

Linda asks, "What's she gonna do when she doesn't like it? Throw me out of the house to sleep like a mermaid on the beach?"
