I went to work licking and sucking her dry. Her clitoris hardened and began to peek through the folds in her ample lips and clitoral hood. I took her ...ady penis in my mouth and licked and flicked it with my tongue sucking it as far into my mouth as it would go. She gasped and gave a shudder ,her hands came down to my head encouraging me on. Oh lick it my little fucker she moaned oh yes give it some flicking you little horny bastard fuck your mums clit you know I like it. I obliged and sucked. Suddenly she looked up and noticed us watching her."God," she sighed, "what now?" Having fun?" I asked innocently."What?" She responded."Feeling good?" Peter asked emphasizing the word 'feeling'.Our sister knew we had caught her out, her hands guiltily dropped to the couch and she uncrossed her legs."What if I am?" she said defiantly."Well we could help you." I laughed.I'm not quite sure why I said it, probable to get a rise out of her; she looked at me then at Peter."You two." she laughed,. .. uh ... don't change the sheets afterward. I haven't had that smell in my bed for way too long." You are a pervert, Lena," Gail laughed. "You kids have fun. We'll try not to disturb you." They left."Where are they going for the weekend?" I asked. "I feel bad about kicking them out of their apartment." You needn't. We talked about it this summer and everyone was fine with it. I paid for a hotel room for them and a nice dinner tonight. We won't be disturbed," Elaine said as she came into my. Her full breasts sagged a little, but their pink nipples stood out like beacons on two hills. My gaze followed the movement of her hands past her navel, over her belly, to the small patch of red pubic hair. The vision of her protruding clit hit me where I didn’t want to go. Or a place I denied myself to enter.For the first time in my forty-nine years, I saw another woman’s vulva, her slit, and the shy protruding lips. I was mesmerised by the vision. I wanted to touch it, to feel the smoothness.
