However, as the soundsgot louder, he could not be sure, but he thought they sounded likemoans. A little concerned, he moved quietly downstairs until h...e couldsee into the living room. The sight that greeted him was surprising tosay the least.There was his wife Liz, quiet, shy Liz, on all fours while her oldersister was pushing a rather large dildo in and out of her pussy whileLiz was moaning in obvious enjoyment. He did not realize it at first,but Susie had been waiting for him to appear. “Sorry. “Now,” Mark said, “if that was not Communal self-help, I had never seen a better example!” Both couples, by mutual agreement deciding to restricted their swapping to just the weekends when the pair Megan described as `pain junkies’ were away, so as, in Marks words, “not to get stale, as when all was said and done, they were two friendly couples, not a commune!” It was the wee small hours when the party broke up four sexually sated folk falling into their own respected beds exhausted but happy. When we bobbed back up to the surface, she wrapped her legs around my waist, her arms around my neck and kissed me passionately. My growing erection had to be as obvious to her as her hardening nipples were to me. When the kiss was broken, she said, “I hope you don’t mind me doing that, I don’t know what came over me.” “Not at all – it’s the best sex I’ve had in weeks.” She nibbled on my ear lobe while whispering, “That wasn’t sex – you’ll KNOW it when we have sex.” I kissed her back and said,. She took my t-shirt off and I took her top off. She started to lick my bare chest and also bite it in between. Even I gave some wet kisses on her neck, shoulders and bare chest. I made her turn around and hugged her from behind. I grabbed her boobs which were fitting perfectly in my palms. I was simultaneously kissing and licking her neck.She was pressing her ass on my erect dick and I started to rub her pussy over her jeans.This made her wild and took off my jeans and underwear, went to her.
