The entire area around her asshole depressed as her sphincter resisted stretching the four inches it would need to spread to take in Sally's hand. But...all of a sudden her ass opened and Sally's hand slipped inside. Sally didn't stop, but pressed further until her hand, wrist and a good three inches of her forearm had disappeared inside mum's ass."Oh my God," cried mum. She sat up and looked down to see how much of Sally's hand was inside her. Her eyes widened in shock at the sight, and she. I noticed as she began to toss the greens and other ingredients how her breasts had just the right amount of bounce to them. As usual she was not wearing a bra and the swaying of her breasts had started her nipples to react. I saw her look over at me checking her out and quickly took a sip of tea. I could swear she smiled as I headed out saying I needed to flip the steaks.Five minutes later we were digging in with gusto into both the steaks and the salad. Samantha had grabbed another beer to. By the time we landed on shore the couples were already sunning themselves allowing the sun gods to kiss the boys and girls… This was the first time we really saw them au natural and I must admit all four of them looked good. We fit in really well from a shape and size perspective although one guy had a rather long dick even soft, while the others were standard sensual packages. All of the gals were in good shape with lovely looking breasts, one trimmed very close with only a small patch on top. Then one night we had been to a private function and I was dressed in a black evening gown with a low cut front that did little to hide my global assets. We took a chance and hubby decided to drive the short distance back to our hotel, with myself in the passenger seat. He took a wrong turn and I had him stop the car and fish out the street directory to find out exactly where we were.The town clock chimed on the half hour as we stopped under a street lamp to provide enough light to read the map.
