The moon was shining, making it seem almost like a dull day. She glanced at the sky, as there were no clouds just a myriad of stars.Each twinkling bri...htly in the night sky.She was unafraid, she'd been to this beach many times both as a c***d and as a fully grown woman.Conscious of her own sexual needs and how to achieve those ends.They walked for several minutes, neither talking. Both just watching the night, and where they placed their feet.As he led her towards the place he had prepared, his. She caught herself again in a fog of lust and was able reign it in. "I cant, he's my son." She once again repeated out loud.She walked back to the bedroom and looked into the mirror a one last time to admire her clean shaven body. She ran her hands over her freshly shaved and moisturized pussy. Megan was so right, it felt so sexy. It felt nasty. And again she could feel the rush of moisture between her legs. She slipped on the bra and loved how it cradled her tits and made her exposed nipples. Her dark bush was matted against her pussy from the constraints of her bikini but I could see her labia poking out of the hairy patch. At that moment Beth ceased to be my sister, she was a gorgeous seductive young woman and I was a sex starved young man, nature was about to take over.I pulled my boxers off and we tumbled onto my bed. I kissed her as my hand explored her tits that were large and her nipples hardened to my touch. Our breathing came in gasps as we kissed like two long lost lovers. Nina was only wearing one item of clothing. They made the first spin and the guy doing the spin made sure it landed on Nina. ‘OFF OFF OFF OFF’ they chanted to her. She glanced across at me and without hesitation I nodded. She stood up and slowly removed her dress. They all cheered. Nina stood there naked for all to see. Her aging, slightly over weight body on show. As I said before, her tits were a bit saggy. She is short with a largish belly containing stretch marks. Her ass is large as is her.
