Both dogs were brothers and indeed weighted over 100 pounds each. She asked why they were wearing boots of some type on their front feet and I advised...they were to keep them from digging in the yard. She seemed to accept that lie and was to find out soon what the real purpose of the boots on the dogs front feet were for.The evening progressed well and I lead her off to the room where the night's event was about to take place. I had been drinking several big shots of whiskey and she worried. We were breathing really heavily on each other and I could feel the sweat rubbing between us. “Oh yes, oh ,oh OH YES!” she was getting so horny now. “DESTROY MY PUSSY YOU BITCH” she shouted. So I started lifting my waist so high I thought it was going to slip out. As I lifted up I then slammed down as hard as I could making her scream out in every time. We were getting so fast now and I could feel her about to cum. I moved my hands down from under her shoulders to her ass which I squeezed. I felt like a high-school kid finally getting to kiss the girl he had secretly liked since middle school. It was a silly, exciting, mystifying moment, and I loved it. We stood there just staring at each other for a few seconds, no words necessary.Over the next couple of months we started going out. It was like our one night together had never happened. We acted like two people who had just met and were getting to gradually know each other. Other than a few innocent goodnight kisses, nothing. The two boys were expert in sharing the attention of the two voracious friends. While one thumped away mercilessly at Sharon's arse, the other was simultaneously fucking Tracey's cunt. And then while the girls were in ecstasy, they'd somehow alter positions: the first boy taking Tracey's arse while the other transferred his attention to Sharon's cunt. And then as Tracey gulped in paroxysms of delight, the one took his prick out of Sharon and pushed it into Sharon's arse, giving her again that.
