That feeling of mild panic might have influenced what I said next, as I tried to assure her she was in the upper percentile of beautiful women. "Most ...guys would have fallen all over themselves to get you naked after seeing that."She didn't perk up like I had hoped."But not you," she said."Of course not me," I said, confused. "You're my niece, for Pete's sake. I'm not supposed to have feelings for you like that." Oh," she said again, just as dismally as the first time."What is with you?" I. With a little wiggle I managed to lift myself and sink down on it, but somehow in the process, I succeeded in dunking us both underwater. We separated quickly to rise to the surface, spluttering and laughing."You did that on purpose!" He accused. Laughing, we swam closer to the rocks where we could balance ourselves. This time he sat on a rock close to the edge of the pool that was still in the water so that he could balance himself with me on his lap. I sank down onto him, engulfing him inside. He poured himself a glass of wine from a bottle on the bedside table. He was waiting for someone, but he did not know who.As he was taking his first sip of the wine, the door to the bedroom opened and a woman entered, also naked.She seemed to be about five feet seven or eight tall, and sensually curvaceous. She had chocolate brown hair that fell to the middle of her back in thick waves. Her warm brown eyes lit up when she saw him, and her generous mouth curved in a smile."Have you been waiting. She went back and forth between each breast. As she did Serra commented how feeling horny was so bad and yet felt so good. Kelsey asked if she felt strange at all to which Serra said no she felt normal.After a while Kelsey stopped and Serra said, “Let me do a little something to you.” She reaches across and starts to move her hand down Kelsey’s stomach to her panties and Kelsey makes a comment about how she is close to touching her pussy. “I’m letting my hand wander.” She starts to rub her hand.
