{Context: Liv is a beautiful 19-year-old brunette, and Benji, her step-brother, is a 21-year-old muscular black male.}
Liv never looked at Benji as anything other than her step-brother, yet that was about to change. Her mom and step-dad had left for their yearly week-long anniversary vacation three days ago. Liv thought back to the first night they were gone. She had hosted four of her closest friends and three of their boyfriends for a party with Benji supplying alcohol. They likely had enough to get forty people drunk, let alone nine, and most of them were drunk by midnight, except for Liv's best friend Reagan, who didn't drink, and Benji. By 1 AM, they had all passed out inside. As Liv thought back, she only remembered one other thing about the night, as faint as it was. She had woken up in the middle of the night, needing to use the bathroom. As she did, she heard quiet moaning and faint clapping coming from the guest room where Reagan and her boyfriend Jake were supposed to be sleeping. At the time, she thought nothing of it, yet Reagan told Liv that Jake had gotten picked up a little after midnight, well before she had heard moaning coming from Reagan's room. Liv had been thinking about this since and finally decided to confront Reagan about it.
As Liv called Reagan, thoughts raced through her head. Who was in there with Reagan? She immediately suspected Gary, another of her friends' boyfriends. She always thought he seemed disloyal, constantly hitting on her and the other girls. Yet Reagan would never fuck him, right? Her thoughts were interrupted, though, as Reagan answered the phone. "Hey, girl! What's up?" Reagan answered as happy as she always sounded.
"Hey, uh... I have a question that I've meant to ask you. About the night of the party." As Liv spoke, Reagan could tell something was wrong purely from her tone.
Much less happy sounding now, Reagan would reply, "Yeah, what is it?"
"So, I woke up late after everyone has passed out and... when I walked by your room, I heard moaning inside. I assumed that it was just you and Jake, but you said that Jake left earlier. So uh... who was it?"
"I... well... I was... masturbating. Yeah, I was mastur-"
"Reagan, come on. I literally heard clapping too. So either you have balls connected to your hand, or you're lying to me. It was Gary wasn't it?"
"No, Liv, it wasn't Gary. I... Promise you won't get mad first."
"I won't get mad! Just tell me!"
"Fine... It was Benji."
"Wait, what the fuck? My brother? What the fuck, Reagan! Did he make you?"
"No! I was going to the bathroom, and I accidentally walked in on him, and I saw his... you know... and it was huge. Like way bigger than Jake's. Then one thing led to another and... well yeah."
"Jesus Reagan! What the fuck! I... I gotta go..."
"Wait, Liv! I'm sor-"
Liv hangs up the phone and stays motionless, shocked. She looks at herself in the mirror, running her hands through her hair and replaying the conversation over again. Not only had Reagan cheated on Jake, but with Liv's step-brother at that. Yet, it almost made Liv curious. What was so great about Benji that it compelled Reagan to cheat with him? Wanting answers, she would move into the living room, which happened to be next to the in-house gym. She turned on the tv and silently waiting for Benji to end his workout. After a little while, he would finish, and, as she suspected, he headed to the bathroom for a shower.
When she heard the water running, she made her move, silently walking up to the bathroom door and slightly opening it so that she could peer inside. As she pushed open the door, she could see just her brother's backside as he washed himself. Now that the idea was in her head, she couldn't push it out as she looked over her step-brother's body. He was 6'4", 219 pounds of muscle. Additionally, he had a tattoo sleeve on his right arm that complimented his clear dark skin. Slowly, he turned, revealing what she had been looking for. Precisely what Reagan said, it was huge, and it didn't even look like he was hard. An audible gasp escaped her lips as she saw it, immediately moving away from the door, not wanting to risk him catching her. She left back to her room, yet she knew that she didn't want this to be the end.
Later that day, Liv was letting her mind wander in her room, always somehow ending back on Benji. As she saw him walk out to the pool to sit, she decided it was time to make her move. She didn't know how she was going to do it, but she was. She slipped off her clothes and would move to her closet, grabbing her favorite bikini, then quickly putting it on before looking at herself in the mirror. She was never ugly by any sense of the word, but she had never considered herself hot. She had long wavy brown hair, which nicely fell on her slightly tanned shoulders. Otherwise, she had a more petite figure, at 5'2" and 124 pounds. With B cup breasts, most of her weight went to her ass. Liv felt as confident as ever when she put her red bikini on, not leaving much to the imagination. She walks to the backyard pool, where her brother was sitting down, sunbathing. Immediately she could see her brother's eyes on her, though she tried to hide it. His offset abs were on display, as he was only wearing a pair of shorts. Liv approached him with a smile on her face.
"Hey, Benji! How do I look? I'm thinking about having a pool party, so I'm trying out bikinis." She smiled at him, trying to act as if she wasn't showing off.
