My top came off and so did his shirt. After sucking on my titties, he reached down to unbutton my jeans and I had a moment of panic. I reached down to... stop him and lied, telling him I was on my period. He made a sour face and then dropped his pants. "Will you suck my dick?"Sucking dick always makes me wet. I got on my knees and serviced Zach's dick, which was smaller than I expected it to be. I could fit the whole thing in my mouth without having to push his head into my throat, but it was. " she kissed me on the lips, just briefly and smiled again. "Thank you."Milly didn't help my erection to subside either by moving forward and backward on the stool."I'm in love," she said dreamily and pouted prettily as Sarah slipped back into her skirt."Let's eat," she said, and we also got dressed to follow the siblings back out into the garden.The swell of Sarah's sexy little bottom was just visible beneath the tiny skirt as we walked behind them and I knew that Milly was itching to be. It had done wonders for their marriage. The remainder of the guests had arrived and I was introduced to everyone and warmly welcomed. After several drinks and dirty dancing to several songs, I was pretty horned up and wanted more than anything to take Lynn over to the sofa and fuck her wild. Two of the other couples had already swapped and the two wives were facing one another French kissing one another while the husbands fucked each other's wife in the doggy position. The scene was. ‘Just remember what I’ve told you. Show him you’re wife material. Show him you know your womens’ work.’ The door slipped closed, and her hand squeezed me, her expression very excited. I asked what kind of womens’ work was meant. ‘Hmm, well,’ she said seductively, leaning closer. ‘I think she meant… cock worshipping. She always says, a good girlfriend sucks cock, but a good wife worships it.’ I shivered, thinking about being with this little teenie bopper tonight. She looked at me seductively.
