Ellie was laying facedown on a towel near the pool, soaking up the sun while her parents were out having lunch with old friends and Jason was in the house. Her 19th birthday was coming up soon and she wanted to have a nice golden tan for her party. It had been a month since the day Jason caught her taking dirty pictures and used that to blackmail her into sex.
Neither of them had mentioned it since and nothing had changed in their relationship. It was like it never happened. The only thing convincing Ellie otherwise was that she couldn't stop thinking about her brother's cock. She knew it was wrong, but she liked to think about his cock slamming into her from behind when she was touching herself.
Ellie would never fuck her brother again though. They were lucky that she didn't get pregnant, because she wasn't on the pill. She couldn't risk that happening again.
Jason was sitting at the kitchen counter drinking a beer, staring at his younger sister through the glass wall separating the kitchen and the pool area. Tiny blue bikini bottoms only just covered Ellie's perfect little ass, and the matching bikini top was tied behind her neck and behind her back. The curve of her ass made Jason's cock start to swell, as he remembered staring down at her cute little asshole a month earlier when he'd caught her in her room.
He hadn't stopped thinking about that day either. Unlike Ellie, Jason couldn't wait to do it again; he was just waiting for the right opportunity. Today was finally that day. He finished his beer and got up from the kitchen counter, taking out his phone and scrolling to the video he wanted. Smirking down at the image, he strode out the back door and walked over to Ellie, his empty beer bottle forgotten on the counter.
He stopped when he was close, and she hadn't noticed him yet, so he took this moment to admire her up close. Her face was tilted towards him and her eyes were closed, and her full pouting lips just begging to suck his dick.
He grabbed the bottle of suntan lotion off the table and walked even closer until his shadow fell over the curvaceous body of his tempting little sister.
Ellie opened her eyes and saw Jason standing above her.
"Hey Jason, what's up?" Ellie said casually, trying not to let it show in her voice that she was incredibly horny from remembering his cock in her tight virgin pussy.
Jason wordlessly poured some suntan lotion onto his left hand, knelt down, and started to massage it into her back. With his right hand, he tilted his phone screen towards her and hit play.
Ellie's words from a month ago poured out from his phone. "I want my big brother's cock in my tight little pussy. I'm such a fucking slut for my big brother. Please fuck my pussy, I need your cock inside me, please, I need you. I need my big brother's cock to fill my slutty pussy with his hot seed."
Jason stopped the video there. Ellie's jaw dropped in horror. She had no idea he had filmed her, and would have never thought that he would do something like that to her. She was mortified that she had begged for her brother's 'hot seed' to fill her pussy, but that didn't stop the unconscious shock of pleasure through her body at hearing herself ask for such dirty things from her brother.
Putting the phone down, Jason resumed rubbing the lotion on Ellie's back, using his now free right hand to undo the back strap of her bikini.
"What do you want?" Ellie whispered, and Jason could feel her body tense up beneath his hands. That only made his cock swell even more.
"I want that pretty little mouth on my cock again, and unless you want all your friends to see that video, you're gonna want that too," Jason said coolly.
Ellie thought that since a month has passed with no mention, that that was the end of it. She didn't think Jason would approach her again, and she definitely didn't think that he'd recorded her last time. She didn't want to fool around with her big brother, it was so wrong, but what choice did she have now? And the thought of his huge cock in her mouth again had her dripping, even if she thought she didn't want to do this again.
She turned and sat up on her side, holding her bikini top on with one hand and using the other to balance. Jason rocked back to crouch on his haunches.
"Fine," Ellie said, trying to ignore the wetness pooling between her legs. She didn't want Jason to think she was desperate for his cock already.
Jason grinned. He knew she'd agree. "I'm sure you understand that, just like last time, you have to do everything I say."
Ellie nodded.
"Good," Jason said. He stood and walked away from her to a deck chair by the pool. He sat down, undid his pants, and pulled out his huge semi-hard cock. "Well? What are you waiting for?"
Ellie felt a jolt of pleasure in her pussy as she remembered the last time he said that, and then felt instantly ashamed for wanting this so badly.
Suddenly Ellie had an idea. He was looking so cocky, enjoying his little power trip so much, and she wanted to take back some control. Slowly she got on all fours, releasing her bikini top and letting it dangle uselessly around her neck while her full tits swayed beneath her in full view. She started to crawl over to Jason seductively, a predatory gleam in her eyes. She wanted to make him want her as desperately as she wanted him. She wanted him to beg. She was sick of being the one in his power.
