As the sun beat down, his daughter stirred, reaching down to adjust her towel once again. She hiked it up further, exposing the bottom of her cheeks, and folded the top over to ensure her hips and waists would still get bronzed by the sun. From Adrian's viewpoint, he could now easily see the crack of her vagina between her slightly spread legs. His mouth watered and his thrusts grew more urgent.
That was all he needed to put him over the edge. He grunted as his cock began to throb and jerk rapidly, pouring his pent-up semen into his wife's lubricated pocket. Emily felt his fertile offering filling her up and she, too, climaxed. Her muffled moans echoed against the sink basin, as she lowed from behind her husband's firm grip. Her legs quivered weakly beneath her and her feet slipped on the sweat-slicked floor. Eventually, having spent his load, Adrian's pace began to slow and he slipped out of her pussy. As his dick exited her body, a dollop of their mixed cum followed and slid down his wife's leg.
Adrian sighed, pulled up his pants, and caught his breath. "God, Emily, I really needed that. You're so sexy."
Emily put her twisted bikini bottoms back in place and grabbed a fistful of ice cubes from the freezer. "I'm not the only one in this family who's sexy."
Adrian gazed out the window as she dropped the ice cubes into the lemonade, one-by-one. Outside, the two girls had flipped themselves onto their backs and were chatting idly. Trendy sunglasses covered their eyes. With the clarity of mind that only comes after an orgasm, he said "I don't know that I'd call her sexy, exactly. She's our child, after all."
Emily walked over to her husband and yanked at the waistband of his pants. His attention snapped to her and she looked him in the eyes and said, "I wasn't talking about Elle, I was talking about you." Adrian felt like he had been caught, and excuses began to race through his mind. But then a wicked grin crept across his wife's face and suddenly she reached down his pants and dropped in the remaining ice cubes. Adrian howled and cursed at the unexpected prank.
Emily cackled and then retreated out the back yard, pitcher in hand and thighs streaked with pearls of semen. She approached the two young girls laying on their towels. "Hey you two pussycats. You getting enough time in the sun?"
Elle glanced up to acknowledge her mother and saw she was topless. "Oh my god, Mom!" she shot out. "What if someone sees you?" Nat wrenched her head up at the question to see Emily's bare breasts once more.
Emily replied frankly, "You're one to talk, honey." Elle blushed. Her mother was right. If anyone should have been concerned about people seeing something, it was her. Emily continued, "I just don't want any tan lines."
Nat couldn't believe she was seeing Emily in such a state for the third time today. Yet this time felt so different. She wasn't so shocked, so taken aback compared to the morning. This time she felt comfortable, even envious that the woman had such confidence. She looked her up and down, really sizing her up for the first time. Emily had the perfect proportions and beautiful hair. Her smooth, already bronzed legs glistened in the sun. Her breasts stood out, capped by tempting, pink nipples. Nat found her adrenaline pumping, still quite turned on from the pool, and ready to take advantage of this situation. She wanted to impress Emily who, after all, had already seen her topless twice today. "That's a good idea! No tan lines!" she giggled. She untied the back of her suit and pulled the top over her head. She was sure Adrian would be able to see her from inside, but she was feeling brave.
Emily smiled proudly at her, then asked, "Does anybody want any lemonade?" Both girls cheered. As she poured the glasses, Emily's eyes flashed only momentarily to the kitchen window. Beyond the windowpane, Adrian suddenly wished he hadn't just cum, because he felt the show was now ten times better. As he prepared the meal they were all to eat, he kept an eye on the three girls. They moved around the back patio, sometimes lying on their backs; Nat's small breasts exposed to the summer rays; sometimes lying on their fronts with their toes pointed out; sometimes sitting cross-legged and playfully teasing one another. At other moments, they took extra care when reapplying each other's suntan lotion, sighing softly at the attention.
As he was finishing up, Adrian turned his back on the window, only to hear a high-pitched shriek. He identified it as his daughter's. Before he could turn around, the back door crashed open as Nat trampled in, cackling maniacally. He looked up and saw her grinning out the door, gripping a towel in her hands. Elle stalked in, a look of consternation on her face, and a lack of anything covering her hips. Adrian put together that Nat had stolen the towel that his daughter was wearing in place of the trunks she lost. "You kids," was all he could think to say, as he stared at his bottomless child and her topless friend.
Nat shrieked again and blushed, suddenly aware that her bare breasts were on display in front of him. She used Elle's towel to cover herself from his gaze, but Elle snatched it away from her. Nat hooted in embarrassment and crossed her arms to cover her nipples, ducking around the corner, "Sorry, Mr. Rowan!" she yelled.
Elle strode purposefully after her, calling back to her dad, "Dad, we're not kids!"
"No," Adrian sighed aloud to himself, as he watched the two disappear down the hallway and climb the stairs, "No, you are not."
"They're not what?" Emily asked, coming inside and startling Adrian.
"They're not... going to give me a moment's peace."
"No," Emily agreed, leaning her head on his shoulder, "I don't think they ever will."
