"Damn it, Sheila, I wanna fuck!"
The sound of the young man's demanding voice brought Trudy Robinson up short. She recognized that voice. It belonged to Clint Rockwell, her teenage sister's current boyfriend.
Wow, Trudy thought, what a late evening walk on the beach can teach you!
Cautiously, she made her way to the top of a sand dune and peered over. There, on a blanket, was her younger sister and Clint, naked. The sight of the two beautiful nude young bodies made Trudy's own pussy gush. "No, no, we can't..." Sheila protested. "I know you want it," Clint said, his voice softer now as he ran his hand up and down her syrupy cunt. "You're wetter than hell... c'mon, let's do it."
