A Wife's Secret Desire

Katie is a good wife. A good wife to a good man. She'd never even considered the charms of another, so when she met her daughter's fiancé, she just couldn't understand her near obsession with him. Caleb was tall and fine with a great smile, and he absolutely became the center of her unconscious and conscious mind. What is she going to do? ~~~~~ PG Excerpt ~~~~~ "C'mon, babe!" Frank laughed and marched down the stairs, keeping a hand on the banister.
Katie couldn't believe it, seeing her normally straightlaced husband walking down the beach nude, in full view of the neighboring home. As he walked away, she couldn't help but admire his physique. As an active man, Frank was still in fine shape for a man his age, but he'd never been much of an exhibitionist. To see him walking across the sand in view of strangers was very exciting and new. It was a beautiful day, and it's often said that late September in Florida is Mother Nature's gift to Floridians.
Schools are back in session, tourists have returned home, and it's the perfect temperature outside, in the mid-80s. Thick clouds moved across the sky, making it obvious that the afternoon would be full of thunderstorms. As locals know, if you're going to enjoy the sunshine, do it early. Katie took a last look at her husband and then slipped out of her jean shorts, untied her pink bikini top, and then stepped out of her sandals.
She darted into the house and grabbed sunblock and towels from the beach bag and headed down the stairs. By the time she got to the sand, Frank was already wading into the low surf, and Katie glanced down the beach to find the other couple looking at them as they set up their chairs. Katie waved and then hurried toward the water. The ocean temperature was perfect, and the curvy brunette waded out to her husband, who took her in his arms and kissed her in the knee-deep surf.
"Happy anniversary, babe, " he said, and Katie shuddered to feel his naked body against hers as the waves splashed up their thighs."You certainly are full of surprises, " she said with a wolfish grin, and noted a strange smile come over his face. Perhaps she would have thought more about his expression, but Frank turned and pulled her deeper into the waves. When they were waist deep, he turned and fell backward into the water, letting the waves wash over his head and he relaxed, floating on his back, rocking in the low surf.
Frank laughed as the cool water washed over his body and opened his arms for Katie who giggled and leaped towards him, swimming into his embrace. The ecstatic couple spent a couple of hours like castaways on a deserted island in a romantic movie, frolicking in the waves, lounging in the shallow water, touching each other, laughing and kissing. In a perfect world, they might have made love on the beach, but feeling the sand, constantly stirred up by the waves, between their bodies kept either of them from getting too adventurous.
When finally, Frank and Katie collapsed on the wet sand, the water ran up to touch their toes, Katie noticed Frank's body was getting pink in the sun. "I have another surprise for you, " he said, and that strange smile returned. In delighted curiosity, Katie rolled onto her right elbow and leaned across Frank's naked body and smiled. "Really? I can't wait to see it, " she said. Frank glanced towards the house and then looked back at his wife.
"It's up there on the deck."Perplexed, Katie looked at the house, and her heart jumped in her chest. It was Caleb. He wore a pair of Bermuda shorts and a tank top, and was leaning against the railing, looking out over the beach. Looking at them. In shock, Katie met her husband's eyes."Frank?" she whispered, not knowing what to say.
