It was far enough off the beaten path to never see another person. Her retreat was very well appointed with all the amenities. She lay nude upon a lar...e, flat rock in the sun, her curvy body glistening in the late Summer sun. She often roamed naked. Her life was ordered and controlled, so when she had free time, she often retreated here alone, to lose control, and be free of the life which confined her. Lana Baxter had long beautiful chestnut brown hair, which she kept upswept in a strict bun. "OK I'll do it!" I announced softly.Chris laughed "you didn't hesitate".My arm snaked around her waist and I kissed my big sister soft lips. She put her hand on my chest "one minute" and stood removing her thong, and he freshly shaved pussy was there. I stood and removed my t-shirt, sneakers and socks, leaving my gym shorts on.Sis moved to me and I was holding the most beautiful naked sister in all the world. Our lips locked together and tongues darting into each other's mouth. Chris looked at. I moan into her wetness as she pushes down on to me, grinding my face in a slow, circular motion, my tongue taking in what she allows me. Her circles transition into a vertical glide, her clit dancing on my tongue before entering her wet folds, then tracing along her perineum before finally settling on her beautiful asshole, where she lingers deliberately, urging my probing.I do as I am bid, pushing my tongue into her tight opening, probing, teasing, tasting, her pussy enveloping my nose and. I had never been with another woman, nor had I ever really wanted to. Well I guess now I was going to find out.As Susan began to moan and groan, Brad abruptly stopped his oral activity. Before I could get out a muffled cry of protest, I felt the engorged tip of his penis at my slit; his cock worked itself between my lips and closer to my ever-waiting hole. I took his cock and guided it into me. The tip started to penetrate and then he stopped. He slowly withdrew a little and then with a thrust.
