“Yup, I’m all set!” Jimmy said, trying to sound casual; hoping his sister had not noticed his rising boner. He prayed for it to deflate, but when he saw his sister’s tits nearly exploding from the very small, white, separate top, he knew he would have no such luck. His cock twitched as he gazed at the swells of his sister’s breasts, glistening from the lotion she had applied to them.
“Let’s go then!” Susan said, turning and heading toward the beachfront shore. A slight sway filled her hips from the knowledge that her brother was gazing at her sweet ass.
On the beach, Susan lay in the hot sun pretending to read her suspense novel but secretly watching Jimmy spread lotion on his body. Susan couldn’t help but feel spasms shoot through her pussy as she watched her brother’s slender, toned body flexing with every move. She licked her lips before realizing what she was doing and pushing the lustful thoughts from her head. She returned to her book as Jimmy put on his sunglasses and leaned back on his hands, soaking up the scenery, which was filled with nubile, young girls nearly half Susan’s age.
After soaking in the sun for about thirty minutes, Jim decided to cool off. “Well, I’m going in,” he said, glancing briefly at his sister as he made his way toward the clear, blue water.
“Okay,” Susan replied, gazing at her brother momentarily before returning to her book. But her thoughts returned to Jimmy, as she gazed at him through her dark glasses, running a long, red fingernail across her bottom lip. Susan set her book down and allowed her mind to wander, as she continued gazing at her little brother who, after cooling off for a few minutes, had struck up a conversation with a young girl.
Susan wondered if her little brother was still a virgin? He certainly had the looks to get laid, but his focus on his studies had prevented him from developing social skills until only recently. Susan wondered if the girl he was speaking to was his type? Her mind envisioned the two, young kids fucking, as she bit her bottom lip and squeezed her thighs. Her mind flashed a vision of her brother’s cock slipping between the young girls lips, as a moan escaped Susan’s lips.
“What is wrong with me?” She whispered to herself, standing and deciding she needed to cool off herself. Heading toward the foamy water, Susan could feel several men’s eyes upon her as her small, tight body swayed as she walked. She worked hard to stay in shape, so she welcomed the hot stares, which now included her brother’s.
“Going in?” he said, watching his sister walk by him and the young girl.
“Yup,” Susan replied, noticing the ice-cold stare from the young girl. Susan waded into the water, letting the coolness relax her as she sunk in to her neck and turned. Her brother had ended his conversation with the young girl and returned to his seat, sitting up and gazing in his sister’s direction through his sunglasses.
Susan swam and splashed, bouncing and turning, letting the water drip from her wet body as she subconsciously put on a sexy show for her brother. After a few minutes, she ran her hands over her hair as she stood in the water facing her brother. Moisture dripped from her plump breasts, as she discretely glanced in her brother’s direction, while adjusting her g-string at her hips. Jimmy’s head seemed riveted in her direction, she noted, smiling. His sunglasses seemingly pointed right at her, as she began to make her way back to their spot.
“Phew!” she said, reaching their settlement and grabbing her towel. “That felt good!” She said, toweling off in front of her brother, as he gazed up at her through his glasses. A noticeable bulge was present in his trunks.
Jimmy Watson gazed lustfully at his sister. He hadn’t really realized that his sister’s white bikini might be transparent when wet, but he now sat gazing at her hard, dark nipples visible through the semi-transparent, wet material. He let his gaze wander to her wet mound, which displayed the slightest pink spot with a thin, dark line running down the center of the wet cloth. Jimmy’s cock uncoiled further, as he adjusted himself and gazed at his sister’s pussy through the wet material. Susan sat back on her towel and turned toward her brother.
“Put some lotion on me?” She asked, holding the tube of sunscreen up toward her brother, as she gazed at him. She had put her sunglasses on again.
“Uhm, sure,” Jimmy said, grabbing the tube quickly but taking his time in moving toward her, hoping his sister would turn away and not notice his hard cock. Luckily for him, she did.
“Thanks,” Susan replied as she lay on her stomach and reached back to unsnap her bikini top, letting it fall to the sand. The creamy, white sides of her breasts were barely visible to her brother, as he began to rub lotion across her back. “Mmmm,” Susan moaned, her head to one side and resting on her forearms. “That feels good,” she added, as her little brother rubbed and massaged lotion across her back, briefly swiping the sides of her breasts. As he traveled further down toward his sister’s exposed ass cheeks, he wondered momentarily whether to continue, when Susan spoke. “Make sure to get my butt cheeks, or I won’t be able to sit down the rest of the week, and it’ll be your fault!” she kidded, as she glanced back at her little brother and grinned. Her breast rose slightly, as Jimmy’s eyes caught a brief glimpse of nipple, before he recovered.
“Is that humor?” He quipped, trying his best to keep the conversation light and hope that his swelling cock would deflate. As he rubbed the lotion across his sister’s sumptuous cheeks, she moaned again, lifting her hips slightly. Without thinking, she spread her legs a bit and gave her brother a view of her mound from behind, and the indentation that her slit was making against the white cloth of the bikini g-string.
Jimmy Watson’s cock hardened to full staff for his sister. And Susan Watson’s cunt was soaked for her brother. Yet, neither brother nor sister realized or acknowledged the other’s desires. At least, not yet.
Jimmy glanced around briefly, wandering if anyone was paying them any attention. But, no one did. Even the young girl with which he had struck up a conversation was gone. Jimmy did his best not to think of his sister’s body as he finished rubbing lotion on it. “There you go,” he said throwing the tube down next to her. “Protected by Ethylhexyl p-Methozycinnamate,” he added with a wiseass tone.
“What?” Susan grumbled, not getting his reference to the active ingredient in most sun block.
“Nothing,” Jimmy said, chuckling, as he lay on his stomach next to his sister, only a bit lower, so that his gaze rested on her exposed, glistening asscheeks.
“You are so weird,” she replied, turning her head to look down at him. They gazed at each other through their sunglasses, neither saying much as the hot sun soaked into their already glistening bodies.
After several hours on the beach, brother and sister walked to a nearby food stand and had lunch. Susan continued to sway and flaunt her sexuality for her brother, convincing herself it was more for the men on the beach than anything else. And Jimmy continued to take in his sister’s beauty, as she walked ahead of him, bent over in front of him and brushed up against him when they walked. For his part, Jimmy fought hard to keep his raging hard on under control. He longed to whip it out and stroke it to orgasm, but the thought only fueled his raging hormones. And so, he forced his mind to analyze his surroundings: What was the bacteria level of the water? What was used to make his fruity drink blue? And of course, what were the odds of a seagull shitting on him?
He continued these thoughts as they made their way back to their spot on the beach and hung out until late afternoon, when Susan had finally had enough.
“Well, squirt, stick a fork in me I’m done,” Susan said, turning toward the hotel. “You staying longer?” She asked.
“Yeah, just a bit.”
“Okay, see you inside,” Susan replied.
“Okay,” Jim said, laying back and staring up into the sky through his sunglasses.
Twenty minutes later, he grew bored and headed back. In his hotel room, he dropped his belongings as he heard the sound of the shower. He walked over to the doors separating his room from his sisters, which were still both wide open, and cautiously stepped into his sister’s room. Susan was in the shower. Immediately, Jimmy noticed that his sister had left the bathroom door half open, as she hummed a pleasant tune.
Jimmy wasn’t sure what possessed him to do it, but he had a sudden urge to see if he could glance his sister naked. He quietly walked over to the bathroom door and peeked inside. To his disappointment, his sister was hidden behind a heavy curtain. Just then, the shower stopped running, as Jimmy’s eyes widened and his heart quickened. Quickly, he backed away and went back into his room, stopping in the doorways separating the rooms. Hidden mostly in his darkening room and peering through the crack in the doors, he could see the shower curtain in the bathroom mirror, as it moved aside and his naked sister stepped out. He caught a glimpse of her pert tits, capped with raspberry nipples, hardening from the sudden breeze. Jimmy had a hard time seeing his sister’s crotch, as he shoved a hand into his trunks and stroked his cock.
As luck would have it, Susan swung the bathroom door fully open and toweled her hair, as her little brother now gazed at her stubbled mound, his cock growing as he fisted it harder. Without warning, he lost his load. The sexual torture that his sister had put him through earlier had brought him closer and closer to the edge, so that now, without realizing it, he had orgasmed within minutes. His semen soaked into his trunks, as he backed away and headed quickly into his own bathroom to shower.
