"I'm not doing it! You do it!" Nicole argued.
She and Julie stood together, facing the lake. A large boat with at least a dozen teenage boys was passing by. They were clearly partying and getting rowdy, calling out at Julie and Nicole. Several of them made the motion indicating for the girls to flash them.
Ryan stood sheepishly to the side. The three of them had gone for a walk that afternoon and had found themselves at a clearing not too far from Nicole and Ryan's parents' summer lake house. He wondered if Julie really would flash the boys. He had never seen her boobs although they have developed quite nicely over the years. He always fantasized about what they looked like.
"Fine, whatever," said Julie as she lifted her shirt and bikini up in an instant, revealing her gorgeous breasts. Ryan could only see from the side, but what he saw was breathtaking. The side profile of Julie's boob was enough to give him jerk-off material for years, he guessed. It was perfect.
The boat full of boys erupted in applause as Julie proudly displayed her melons. She even shook side to side for a little extra show before pulling her shirt back down. "Think they liked it?" she turned to Ryan first. He nodded emphatically. "Ha! Nicole, I think your brother certainly liked it."
"Ryan, don't be a perv," said Nicole, scolding her brother.
"We want the other one! We want the other one! We want the other one!" the boys suddenly chanted over and over. The pressure was now on Nicole to show hers. Julie cracked up laughing. "Do it, Nicole! They're waiting!"
Nicole laughed. "They want to see mine too?"
"Certainly sounds that way. Do it, c'mon! I did mine!"
Nicole hesitated. She looked around nervously, then out at the boat. All the boys were eagerly waiting for her to reveal them. She crossed her hands and gripped the bottom of her tank top. She turned to her brother. "You look away," she instructed. Ryan obediently turned his head.
All he could hear next was a thunderous applause coming from the boat and Julie cracking up laughing. Nicole must have had her boobs out.
The applause continued and was supplemented by whistles and catcalls. Ryan stared at a nearby rock. The curiosity was killing him. Even though she was his sister, he found himself noticing her breasts a lot more lately. They were large, round, and she always wore clothing that accentuated their shape.
Ryan awarded himself a quick glance. As he turned, he immediately saw Nicole standing, legs apart with her hands holding up her shirt triumphantly. Just like with Julie, he could only see one of her breasts, but its perfect shape was something he will remember forever. Large, fair-skinned, and round. A single pink nipple protruded from her areola. Her thin and trim tummy made it all the more majestic looking.
He quickly turned away before getting caught. Julie continued to laugh as the boys cheered. Nicole finally put her shirt back. "Now they definitely liked that!" Julie called out. "Your boobs are so nice."
"Ok, I think that's enough for today, don't you think?" Nicole asked. "Let's go back and see if my parents will let us drink."
Ryan quietly followed behind the girls. He watched their asses move in front of him. But for some reason he watched Nicole more than Julie. He kept picturing her breasts. He wondered what they felt like. He wondered what they tasted like.
He knew, however, that he'd never find out. She was his sister.
Ryan woke up first. Sun peeked through the blinds in his room, stirring him from a deep slumber. He glanced at the clock. It was eight-seventeen. He turned back over. Nicole was still asleep. She had kicked the blankets off slightly so that just one breast was uncovered. Ryan stared at it, as if in a trance.
It was perfect. Round and plentiful, it draped off her chest. Her nipple, soft and pink, was just the right size for the available surface area. It rose and fell slightly as she slept. To think that breast was in his hands and mouth the night before was still a shock to him. And the fact that it was his sister was even crazier. How did this come to be?
Ryan felt his penis stir. He slipped one hand under the covers and clutched it tightly. He was getting hard. He stared at Nicole's exposed breast as he fiddled with his cock, producing a sturdy erection. Given his size, it would be too obvious if he stayed on his back, so he rolled over, facing Nicole as she slept.
Even though he had known her his entire life, it was in this moment, as the sun shone through the blinds and canvassed her body, that she looked the most beautiful. Like an angel had fallen from heaven. Her brown hair shined as it spread out across the pillow. For some reason, his focus continued to drift to her one exposed breast. It's perfect symmetrical elegance glowing in the light.
He stroked his cock staring at her. He couldn't help it. No more than eight hours ago, he was inside her. He fit much of his penis deep inside the untouchable confines of his own sister. He felt her wetness as he plunged in and out of her. He remembered how they both came at the same time in a climactic moment of mutual ecstasy.
Suddenly, she stirred. Her brown eyes opened with a gracefully slow reveal. She looked comfortable and content.
Ryan froze, hand on his penis. He watched as her consciousness activated. But Nicole's dreamy eyes quickly grew alert and guarded. Realizing where she was, she instinctively covered herself with the sheets. Concerned, Ryan removed his hand from the death grip he had on his cock. He watched Nicole come to.
She pulled the blankets all the way up to her chin. "What time is it?"
"Not even eight-thirty."
"Oh my gosh," she said as she closed her eyes and put her hands on her head. "Ryan..."
He remained silent, sensing an immediate and deflating feeling of guilt. Nicole turned to him as they locked eyes. "What are we doing, Ryan?"
"I don't have an answer to that. I'm sorry," he said softly.
"This is my fault," she said, shaking her head. "I don't know what's happening to me."
"It's ok, Nicole. It's fine," Ryan attempted to reassure her.
"It's not fine!" she grew angry. "It's not fine, Ryan! I'm sitting here in bed with my brother. I'm naked. I had sex with my fucking brother!"
Ryan tried his best to create separation in the bed, by shifting all the way against the wall. Nicole was clearly in anguish and he wasn't quite sure what to do or say. They two of them laid there, naked, for several minutes in silence. Nicole kept her eyes closed, wondering if the whole thing had even actually happened.
"Nicole," Ryan finally broke his silence. "Please don't blame yourself for what happened. Yesterday... yesterday was a very weird day. Everything from the dock to what happened back here afterwards. I think we were all a little charged up."
"Charged up? Really, Ryan? We were charged up so we had sex?!"
Ryan was growing frustrated with his sister's tone. There was seemingly nothing he could say. "Look, I'm just saying don't blame yourself. It's my fault too. And yes, we were charged up. We're human. You're fucking hot and I couldn't resist, ok?!"
