I instructed Karen to strip as usual in our home. She did without hesitation. Betty and I sat on the settee and watched her. She complimented Karen on...her naked body and jewelry.Betty’s hands were stroking me all the while. I told Karen to remove Betty’s clothing. She wore a beautiful black dress. When Karen removed it, she was in a black bra and panties, with matching thigh high stockings. Karen removed her bra, and nipped at her rather large nipples. I let them play a bit before telling her. Originally it had two tunnels to enable controlled release of water, but a third tunnel had been built in 1996 to enable the production of hydro-electricity.The bus then took them through the Lake Argyle tourist village that used to house some 350 construction workers, but had now been converted to cater for tourist. The group were then taken to the boat for their two hour scenic cruise on Lake Argyle itself.Here they were able to explore just a tiny fraction of the waters that resulted from. But stopped. It felt good. It was a good size and when I touched it, it pulsed in pleasure.I didn't know what I was doing, but before I could think it through, I had slid my hand down his pants and had started to jerk him off.I heard a moan in my ear. It turned me on so much that I started to give it more enthusiasm.What was I doing? This is the opposite to what I should be doing. But I could feel myself getting wetter and wetter with every stroke. I started to move my hips now, so I could feel. This started a wave of orgasms like she had never experienced. He did not stop as she shuddered, but fucked her with a relentless rhythm. After a lifetime of orgasm, she felt him wither inside her and withdraw. "Thank you," she said.Mark pushed her forward onto the bed. She flopped like a rag doll. He grabbed her by one ankle and spread her open. She could sense him once again examining her pussy, pleased with its wetness. He straddled her face and began touching her sex. She eagerly took his.
