Soon, I started matching her motions. I don't think I we were doing that for more than a few minutes than I started hearing from Val, "Oh, God, Mark.......I'm cuming, I'm cuming, Oh, God, I'm cuming hard." Her breathing was at a marathon runners pace. I could feel her vaginal walls contracting on my penis and then, Val just let out one long high pitched squeak. I could hold it no more and I shot my load. My breathing did its usual when I came as well. So I stood there, as my dick became. She holds my head and pulled towards her pussy to suck it more.I gave a nice licking and sucking for more than 15 minutes…By this time she came more than 2 times… She holds my tool and told me to fuck her boobs…I put my thick and long tools in her tits and fucked for the next 10mins… She made me lay on the bed and gave a nice blow job for more than 15 minutes…Now we both are ready for the real session…I placed my dick on her pussy and started to rub my tool over it…She was screaming like. Anyway, my friends were sleepy and I decided to cool off in the water. I climbed from the boat into what I can only describe as a beautiful warm sea, lay on my back, and slowly drifted away from the boat. The cooling waters sent delicious shivers through my body, my skimpy bikini allowing the maximum of my body to be exposed. I drifted between the two islands. It was lovely and quiet and hardly anyone else about. Most people on our trip and the boat anchored up nearby appeared to be dozing on. I say my hello's and try to squeeze past them so i can get to the front door where i know i can have my cigarette, but as i squeeze past, i overhear the house mate say to my brother in-law, " what a sexy little bitch " my brother in-law reply's " if she is half as dirty as her sister, she would be a great little fuck " i look back in disgust and was about to scream at them at the top of my voice, but just then my sister arrives and i loose the moment.My sister looked so happy, she was also six.
