It's Sue!!

Ben turned, the pool water rippling around his naked form, and his eyes going wide in surprise and delight. Before him, standing looking down at him, was Sue. She had obviously woken and showered again, cleaning herself of their previous activities. Her hair and body were now dry, but the thing that had made Ben’s jaw drop was that she was standing in black, high ‘fuck me’ platform shoes and the sexiest set of black lace lingerie he had ever seen.

“Ready for round two, sexy?” She said, grinning wickedly, her hands on her shapely hips as she gave them a little wiggle. Ben was speechless, he could feel his cock stiffening almost instantly under the cool water of the swimming pool. Sue turned, flashing him the glorious sight of her perfectly curved ass, covered in the sexy black lace of her lingerie, and began stride, hips swaying sensuously, across the patio.

Ben scrambled out of the water to follow his sister. Sue hearing the splashes as Ben exited the pool, turned her head and caught his lust-filled eye, beckoning him with the same finger that had enticed him into the shower. She reached one of the patio lounge chairs and lay down, her legs spread eagle, straddling the long seat. When Ben reached his sister, his cock was hard and erect, and he looked ready to jump on her and fuck her senseless.
