Daniel's bedroom door blasted open, interrupting him in his work. Daniel looked up to see who was barging into his room. Of course, it was his younger sister. She was pompously standing in the doorframe, confidence beaming in her brown eyes. She brushed her wavy, dirty blonde hair behind her shoulder as she walked up to his desk.
"What are you doing here, Lizzie?" Daniel asked, irritation clear in his voice. He was still in the middle of revising for his upcoming exams.
"Mom and dad just left on their weekend trip," she proudly announced. She was wearing light clothing during the ongoing heat. Her white tank top was tucked into her denim shorts, showing off a lot of her pearly white skin. She bent over to get right into Daniel's face, sitting behind his desk. Her neck was already showing a tinge of red, even though it had barely been hot for a day or two.
"So?" Daniel replied curtly. "What about it?" he asked as he turned his chair back to face his textbooks. Daniel had to spit through another three chapters that day, so he was not in the mood for her antics. Of course, he knew their parents had just left the house, so why did she have to come over to state the obvious? 'Maybe she's just bored,' he guessed. She was eighteen, a year younger than him, and had just finished her final exams. She was now just hanging around, waiting for the results. She could most likely go to her first choice university if they were positive.
Lizzie wasn't daunted at all by Daniel's dismissive attitude. "I was just thinking," she mused cheerfully, while she forcefully turned him back around in his chair to face her. "That this would be the perfect time to give you another 'challenge', wouldn't it?"
Daniel's eyes widened and his heart skipped a beat. He looked straight through the gleeful expression on his sister's face, aware of the hidden meaning behind her words he had long been oblivious for. He felt a jolt in his crotch, after which he put his hands to try to comfort it. "Does it have to be right now?" he tried, his composure melting away at a rapid rate.
"Oh?" Lizzie replied surprised. "Don't you even want to try anymore?" she asked him, disappointment in her voice. "So you don't mind me sending a few pictures to mom right now?" Lizzie backed up to get her phone out of her back pocket, already navigating to her gallery.
"No! No, I mean please don't do that!" Daniel scrambled to stop her. Lizzie expectantly looked up from her phone, although her thumb kept scrolling through her photos. "I-I just tried to say that I was pretty busy," Daniel tried to explain. "But if you want to do it right now, that's also fine." Sweat was dripping along his back, which was not coming from the heat in his room.
"I hoped you'd agree," Lizzie said happily as she put her phone back in her pocket. For a brief moment, Daniel thought that he had dodged a bullet, but it seemed like it had still grazed him. "You obviously don't want them to know what a pervert you are," Lizzie started. Daniel's heart sank as the humiliation started coming down on him. "Sneaking pictures of your sister when she's wearing her cute bikini on the beach," she continued, running her hands over her naked thighs. "And furiously masturbating to that sight for weeks," she kept teasing.
As Daniel tried to avoid his sister's gaze, he noticed someone standing behind his sister. It was a bit dark in the hallway, but he instantly recognized her. It was Maya, one of Lizzie's friends with whom she often hung out. 'No...' Daniel thought to himself. 'She wouldn't...' His sister was practically shouting that her brother jacked off to pictures of her, while her best friend was standing right behind her. Panic welled up in Daniel's chest. Maya must have heard everything, and Lizzie's words couldn't be spun in any other way.
His sister noticed the anxious look in Daniel's eyes, as his voice was stuck in his throat. She followed his gaze, which was fixated on the girl behind her. "Oh god, you don't have to worry about Maya, Danny," she giggled. Daniel looked at her confused. On what earth didn't he have to worry that not only his sister but now also someone else knew about this?
"Yeah, this is nothing new for me," Maya said as she walked up to Lizzie, putting her hand on Lizzie's shoulder. She reached out with her other hand to show Daniel something on her phone. His mouth fell open while she scrolled through her chat with his sister. Not only were there chat messages from months ago indicating that Maya definitely knew what was going on, but there were also pictures. Dozens of them. Of him.
Daniel knew that his sister had been taking pictures of him. It was hard not to notice her pulling out her phone during one of her 'challenges'. He had just naively assumed that she kept those for herself, probably for even more leverage over him. He had never dreamed that she would directly send them to her best friend. The photos were bad enough, but the accompanying conversations made him look like an even bigger fool.
Seeing that Daniel now believed her, Maya put her phone away. "I was really curious how Lizzie had trained her big brother," Maya said. "You saw that she kept me up-to-date pretty well, although maybe a bit too well," she remarked, giving Lizzie a look. His sister just sheepishly smiled in response. Shaking her head, Maya continued. "Let's just say that I really wanted to see it for myself. But I have to say that I'm not that impressed yet," she voiced to Lizzie.
"Well, he's still Daniel," his sister laughed at the comment. "He can be a huge blockhead," she criticized her brother, "but that's just how I like him." This surprised Daniel. Maybe this explained her unyielding attitude when he tried to brush her off. "Let me show you how to flip his switch, though," she moved on.
'Oh no,' Daniel thought to himself again. 'She can't, not right in front of-' His train of thought was stopped when Lizzie put her hands on her chest. She bent down even further, almost pressing them up against his face. She put her fingers under her cute, firm breasts, pressing them against each other.
"Do you wanna get hard for Lizzie?" she asked in a sugary voice. "Is today the day that Danny is going to win my challenge?" As if someone had pulled the emergency brake, all trains of thought had stopped in Daniel's head. He stared at his sister's breasts, looking at the outline of her bra, barely showing through her shirt. The only reason he got back to his senses was because of the sharp pain in his crotch. He let out a yelp and put both of his hands on his lap.
"Oops," Lizzie said, quickly standing back up and pulling her hands from her chest.
"What happened?" Maya asked curiously, as it was now her turn to get up close.
"Ehm, I kinda forgot he was still locked up."
Maya looked back at her friend with a raised eyebrow. "Don't you do this, like, all the time?" she asked, perplexed.
"Yeah, but I guess I was nervous or something. You wanted to see Danny so suddenly, so I wasn't really prepared," Lizzie tried to explain herself.
"I have been asking for weeks," Maya poked right through it. "You just wanted to show off, didn't you?"
"Okay, okay, you're right. Come on, Danny, let's get to my room," Lizzie evaded losing face. Daniel got up from his chair, while Lizzie had already stormed out of the room. He heard Maya giggle. He saw that she found the whole ordeal endlessly amusing. Now that he took a good look at her, he noticed that the few days of sun had already colored her skin olive brown, in shrill contrast to his sister. Maya was wearing her black hair in a ponytail like usual. She was wearing a crop top and airy shorts, presenting more of her skin.
"Aren't you going after her?" Maya caught him gawking at her. "Or are you too busy?" She turned to face him. She was a few inches taller than his sister, almost matching him in height. She winked at him and mimicked what his sister had done just now. She put her hands under her breasts, hidden behind the tight top she was wearing. She pushed them together just like Lizzie had done. Her fingers dug into her boobs, which were a lot larger than his sister's. She released her grip, making her tits bounce back to their original position.
Daniel hadn't seen anything that sexy for months. He had to manually close his jaw, which had hung open from surprise. This made Maya giggle again. "Let's get to your sister, she's waiting for us," she urged Daniel as if nothing happened.
