"What?" I cried. "Surely not. It would mean I`d be masturbating my sister and you doing it to your brother".. " Why ever not? Where`s the harm? It sho...ld be exciting. I`ll undress fo it". "I`d be seeing you naked for the first time as grown-ups. I`d like that.". While waitng for her to undress in her bedroom my cock lost a little of its hardness, but when she returned, stark naked it came up again. I hadn`t known what a lovely figure she had. No sun-tan but firm breasts with pink nipples, flat. She leaned down to begin biting and kissing my neck again, giving me an angle to start powering my cock up into her from below. I could feel her moan into my skin as I began thrusting my hips upward into her, my skin slapping against her ass with every hard thrust. I could feel cum boiling up inside of me, threatening to explode into her. As much as I wanted to cum into her I knew there was at least one more thing I wanted us to do before we finished. I asked Molly to get off me and turn. I followed her through a small wood lot, and we both saw two sets of footprints leading from the lean-to toward the woods. "I think they got away," she said, smiling for the first time. "I figured them brutes would be raping both a'them by now." You got some whisky in there?" I asked as the noise of a German song reached us.She nodded. "Paw used to make some. White lightning. There was a couple'a kegs left." Where will your ma go?" Nearest neighbor's 'bout a mile down the trail." She. "oh ... let me clean you ... its all my fault," she said, sounding falsely worried. She took my dick in her hand and grabbed a tissue from her night table. She rubbed me for a few moments. The tissue was a bit rough so I asked her to stop. "oh my god I am so sorry," she exclaimed, "its my fault. I think with a bit of saliva it will be better" and before I could react she had taken my dick into her mouth and was sucking it passionately. I felt my balls boiling. A moment before coming she stopped.
