Paul was glad he had come home. Swimming here in his parent's backyard was ten times better than sitting in his danky old dorm room for the holiday. Even if it was just with his family. He was going to miss his friends (Damn them for going to Cancun without him!) and his girlfriend, Rachel. Especially Rachel. He loved their long make out sessions, feeling her warm body wrapped against his on the couch, touching her soft tits. He was hoping to go a little further and maybe get into her pants during the break, but no such luck. She had the money to go elsewhere, too. She was in Hawaii with her family. Oh, well. So he had come home for the break at his mother's insisting. She had pretty much guilted him into it.
"You're sister's coming home," she had said, "Why can't you? We miss you. It seems all you want lately is money..." blah blah blah.
So he had finally relented. At least Brandy was here. If she hadn't come home too then he really would've been miserable. He hadn't seen her in a long time, with them both leaving home for college. Despite what he usually said, he genuinely liked her. She was different than what he remembered though. He almost didn't recognize her when he got home. She was no longer the little annoying tomboy who used to follow him around all the time. A year in college had changed her. She had let her short chestnut hair grow out and had started to dress differently. The tight top she was wearing showed off her chest. Paul absentmindedly guessed she was probably about a C cup before realizing he was looking at his sister's tits. She had on makeup when they met at the airport. She never wore makeup. She's even lost some weight from what he could tell. No more baby fat. She felt like a woman when they had hugged. He definitely remembered that. Feeling her breasts press into him. That was different for sure.
"Hey, loser, get your butt in the house! Mom says dinner in five minutes!"
Brandy was smiling over him at the side of the pool. Paul slowly started to climb out of the pool. Just as he was about to swing his foot up to step out, Brandy reached her foot out and pushed him back in. When Paul resurfaced, sputtering water, Brandy was doubled over with laughter.
"You... should have... seen... the look..." She was gasping for breath now trying to get out the sentence. Her effort ended as she again bent over with laughter. She never saw Paul's hand as it reached up and grabbed her ankle. Now it was Paul's turn to laugh when Brandy shrieked as she hit the water.
"Oh! You! You're deadmeat now."
Brandy was grinning as she grabbed Paul and tried to push him under. She jumped on his shoulders but she was no match for Paul now. He grabbed her around the waist and pulled her back around his body and shoved her under. As she struggled, he quickly countered, moving his hold on her. It was just like when they were younger. Brandy was just too small to get anything over on Paul unless she surprised him. She still squirmed though, trying to grab at anything she could. To be honest, Brandy was enjoying the feeling of Paul's body, of being close to him. Not that she would ever tell anyone, let alone Paul. She'd always had somewhat of a girlish crush on her big brother, and it embarrassed her.
Paul began to notice that this was quite different from when they were younger after all. He was playing with a woman now. He felt her breasts rub against his chest as she tried to turn around and dunk him. He saw her smooth tanned legs under the water. He had never had to worry about what might end up in his hands when he grabbed at her before. All of this started to have the reaction on Paul that it had already had on Brandy. Paul felt his dick begin to stir in his trunks. Brandy felt it too. That was it. Getting a hard-on from playing with your sister was a little too much for Paul. He grabbed her and tossed her into the shallow end.
"Had enough?" Brandy challenged.
"Yea, I'm getting tired from beating on you shrimp. Besides, you need to get cleaned up before Mom yells at the both of us. Go get changed. I'll finish my laps."
Paul spun away from Brandy and started swimming. He wasn't quick enough though, as Brandy caught what he was trying to hide before he turned away. She got out of the pool with a secret smile on her face and walked back in to the house, toweling off as she went.
"Hey! Paul," Brandy whispered, "You asleep?"
Paul groggily glanced up and saw Brandy standing in the doorway. "What are you doing in here? It's 3am," he said. "Go to bed."
"I can't sleep. I was hoping we could talk. You seemed kinda upset with since we got out of the pool. You hardly said a word to me during dinner. Did I do something wrong?" Brandy put on the best pouty puppy-dog face she could. She was trying to sound sincere. She walked in and sat on the bed next to Paul.
Paul immediately noticed what she was wearing. Or more important to him at that moment, what she wasn't wearing. She had on one of his old T-shirts and nothing else as far as he could tell. The shirt barely covered her little bottom. He felt her next to him on the bed. Paul felt himself starting to react again. He cursed himself for noticing and looked back up to her sad face. "Oh, no... You didn't do anything wrong. I guess I just wasn't in a talking mood, that's all." Paul mumbled. He was nowhere near the actor Brandy was. She knew he was lying.
"Are you sure that's all it was? I thought you might be embarrassed..." Brandy trailed off. She scooted closer.
"About what? Why would I be embarrassed?"
"Well, you know... in the pool. I saw you after we were playing," Brandy blurted, "I saw your reaction."
Paul was dumbfounded. He had no idea of what to say. He sat staring at his sister not believing his ears, his jaw in his lap.
