Julie, the driver, was the first to drop her towel on the sand and wade into the water only to her waist. She turned and asked Barb for the soap. Barb... slung her towel over my head, in an attempt at modesty, and went to join her friend. Barb took the soap in her hand and started to lather up Julie’s back. It wasn't long before they faced each other and started to soap each other down. Their motions were not that of a mother washing it's c***d. They were erotic in their movements with Julie. One or two had more flesh on them but that was the only change. Several waved at me. I waved back. ‘Bill, how long have you known that this was a nude day event?’ I asked. ‘Since the beginning. Didn’t Janie tell you?’ ‘No. Not until we were nearly here. Meeting your Louisa was a shock.’ ‘I’ll bet it was. She’s in great shape, isn’t she?’ ‘Yes, Bill.’ What else could I say? Could I admit that Louisa had given me a massive boner and pressed her naked body against it? ‘You want to watch yourself. Suddenly a big wave hit the boat and made her thrust up hard to meet me thrusting down and knocked the wind out of both of us as I shot my cum deep inside her unfaithfull pussy and I filled her with my firtile seed, she didn’t even realise I had cum in her so I continued to fuck her for ages. After a long time humping this lady she asked me when was I going to cum, I just looked at her and then said, “When you want me to!” She then said, “NOW! Cum in side me please?” How could I refuse this. With upward motion I was massaging her inner thighs and sometimes touching her panty for which I could hear light moan from her.My dick was hard by now and I have to adjust so that she doesn’t think bad of me. I asked her to switch and I kept the small towel on her boobs and started massaging by touching her boobs from side and below. Her eyes were closed and was moaning a bit.All of a sudden she couldnt control and got hold of my dick and started pressing it and said I want this as I am.
