Roger asked us if we would like to return to the island where we had made love on the beach. We agreed to go with him and take some food and drink and make a day of it.
Roger was to put up a wind break that would also serve as shade from the baking sun especially as we would not be wearing any clothes because that was the unwritten rule on the island. In fact as we were going down the river Roger said Mary should go down into the cabin and undress, which she did and returned to the cockpit quite naked. She was quite at home nude and did not mind being seen by the occasional angler on the river bank.
She looked great and I had difficulty keeping my hands of her and as we set off across the estuary to the island Roger went forward leaving Mary and myself in the cockpit and the temptation was too much for me. I unzipped my shorts and liberated my stiffening penis and standing behind her I rubbed it up and down between the cheeks of her bottom. After a while she bent forward and allowed me to slip inside her vagina.
Once we landed on the island Roger erected the wind break and said that we could enjoy a day in the sun. At this state of the tide the water was fresh and not at all salty. We had a swim and a little cuddle on the edge of the water which was quite cool and caused Mary’s nipples to firm up and become very sensitive.
A bit later after we had settled in on the island Roger announced that he had a meeting further round the coast and he would be back for us later. He left us naked on the island and took the boat together with our clothes. We set off for a walk along the beach and Mary announced that she had bought some condoms to keep her vagina clear of sperm running out after we had made love as she knew we would.
There were other people there many of whom were engaged in some energetic love making. Some we noticed were having oral sex and others with his penis up her bottom. I asked if Mary would like to try either of these options. She agreed to oral but drew the line at anal entry. We were invited to join one couple who were doing oral on each other and we joined them without too much embarrassment and I was soon able to bring Mary to orgasm.
I will post some pictures later (sadly no intercourse pictures).
