This story contains incest/taboo sexual contact as well as pee, pain, and a little bondage. If any of these are not in your interests, do not read this. This is my first erotic story.
*****
She was zoning, daydreaming without a care in the world. It was summer vacation—the summer before senior year of high school, and she had nothing to do. It helped that her parents were going to be gone for two weeks on their anniversary cruise. Her mother and step-father—who was the only father she knew; her biological dad walked out long before she was even born—were celebrating their sweet 16th wedding anniversary. With her parents being gone, she didn't have to worry about being yelled at for something or be ordered to do anything. She especially didn't have to be worried about being scolded for tanning by the back pool in her birthday suit, but who had time for tan lines?
The only people who might see her were her 40-something year old neighbor, though she didn't care because she was 18 now, and her older brother—technically step-brother, but since she came around while her mother and step-father just got together, he was really like a brother to her. She didn't care about the neighbor, but rather would be flattered that he would stare at her naked body, and her brother was with his college friends. He had just finished up his sophomore year in college and was the eldest of his friends, having started college late and was a 23 year old soon-to-be college junior. Why not take advantage of being alone in a huge house next to a huge pool?
She had her music playing next to her, loud enough to sing along to it, but not so loud to drown out all the surrounding sounds; she still could hear dogs bark and birds chirp. With a towel propped behind her head as a make shift pillow, she started to doze off. She was awoken by her brother calling for her in the house.
"Joce!!" her brother's voice echoed. "Joce, where are you?"
"Max?" she gasped, quickly unfolding her temporary pillow and covering herself as best as she could. She tucked her bikini behind her back so Max wouldn't see it lying on the floor. The sun had begun to set and it had started to get dark.
As soon as she had properly covered herself, her brother walked out of the patio door towards the pool. His shorts were tight and he had already taken his shirt off, revealing his tight, muscular body. Even though they were brother and sister, she still was secretly, painfully attracted to him.
"Jocelyn, how was your day?" he asked, standing across the pool from her.
She was glad that it was semi-dark so her nakedness wouldn't be easily seen. "Good, Maximillion" she answered. "How was the time with the boys?"
"Awesome," he replied, sliding his basketball shorts off. His compression shorts underneath left little to the imagination and Joce had a hard time not staring at the bulge they outlined. "A few of us had a quick b-ball game before the rest of the guys showed up for our softball game."
He walked to the edge of the deep end of the pool and dove under water. After he surfaced he shook the water out of his shaggy dark brown hair before swimming to the ladder and climbing out. As Joce stared as drops of water rolled down her brother's firm body she could feel herself getting wet. She was relatively inexperienced in matters regarding sex; she had only done it a handful of times with a past boyfriend, but she never enjoyed it with him. The only time she enjoyed any type of sex was when she was alone and daydreamed about Max. She started to get nervous as she felt her body respond to her arousal. It didn't help that every time she looked at her brother her eyes always went to his cock.
"Joce, is something wrong?" Max asked his sister.
"No...well, sort of, but it's hard, uhh...difficult to explain," she stuttered. Max stared at her in bewilderment.
"Why don't you relax? Lean back."
"I'm good."
"Lean back and relax," he repeated more sternly. She leaned back and reflexively bent her legs, not realizing her towel was no longer covering her. "Uhh...Joce?"
She opened her eyes and, again, they immediately focused on her brother's cock. This time it was semi-hard and almost pulsing. When Max didn't say anything, she followed his gaze and figured out he was staring at her now visible pussy. She quickly sat up and re-covered herself.
"Oh, my gosh," she groaned, embarrassed.
"Why are you..." he didn't need to finish his sentence for her to know what he was going to ask.
"I was tanning...and didn't want tan lines."
This time, when she was eyeing up Max's bulge, he caught her. Instantly the look on his face changed to a devious, yet sexy grin. He walked towards her, asking, "Want to play truth or dare?"
"Sure," she said as he sat next to her. "I'll go put on some clothes."
"I dare you not to."
"What if I picked truth?"
"Okay...tell me the truth; do you really want to put clothes on?"
"No," she said as her cheeks flushed red.
"I think it's my turn. I pick truth."
"Do you want me to put on clothes?"
"No!" he answered quickly. "Now, I dare you to take off the towel." He leaned back and had a smug grin.
Not being one to back down from a dare, she pulled her towel off. She sat there, vulnerable as she watched her brother's eyes scan her body.
"I dare you to take those shorts off."
Max stood up in front of his younger sister and slowly slid his compression shorts off, stepping out of them before tossing them to the side. Joce let out a gasp as she eyed up her brothers now rock-hard cock. She had imagined what it looked like, using bits and pieces of time she had spied on him in the shower to compose her own idea of what his cock looked like; it was so much better in real life.
"This next one has multiple parts," Max began. "I dare you to lay back with your eyes closed, keeping them closed, and spread your legs."
Eagerly, Joce obeyed. She leaned back on the chair and lifted her legs up, spreading them slightly. It was difficult to keep her eyes closed and not peak, but she did her best. After a few painfully long seconds, she felt her brother crawl on the end of the chair. His fingertips began trailing up her legs to her thighs.
"You're already wet, like a little slut."
Joce could hear a grin in his tone and she snuck a little peak. Max caught her, and he reached out and slapped her bare tit.
"No peaking!"
Joce quickly closed her eyes again as her tit burned after being slapped. She was a little surprised at how much she like being slapped. Max's fingers slowly began sliding towards her pussy, trailing around her lips. She couldn't help it anymore and she peaked again. This time Max didn't slap her tit, but instead slapped her pussy, his hand making hard contact with her clit.
Max leaned in close to her ear and whispered, "You're going to pay for disobeying me." All of a sudden Max's hard cock was forced into Joce's mouth. She sucked as hard as she could. "Look me in the eyes." Joce opened her eyes and looked into her brothers as he slid his cock in and out of her mouth. Every time he let out a moan she got more turned on. Joce's pussy got wetter as Max gently slapped her tits around. "You have such nice tits, Jocelyn. And you are great at sucking dick."
"Thank you, Max," she said as she slid her hands up the back of his legs, squeezed his as and pulled him closer to her, forcing his cock deeper in her mouth.
"Wait here, and don't move," Max ordered as he pulled his cock out of his sister's mouth. "I'll be right back." Max walked off into the house and was gone for a few minutes. He returned with a closed box. "Lay a towel down on the ground and lay down on top of it."
