My older sister blackmailed

... to grab her ass softly, she instantly flinches, but doesn't say anything. I continue to grab her ass, harder and harder, and use my other hand to push up her shirt and rub her waist. "What the hell are you doing?" she asks "Whatever I want" I respond, before pulling down her panties only slightly She then reaches her hand behind her back and swats my hands away, then pulls up her panties and turns around to face me "Why don't you go play video games or something?" she says sharply I frown and look at her, disappointed that she resisted "Because I don't want to" "Well can you stop touching me?" "Why should I?" "Because I don't like it" "Honestly, I don't care" I pause "How about you take off your shirt.. and underwear" I say with a smirk on my face "You want me to get naked.. in front of you?" she asks "Yep" "No way, not happening" "Think about this for a second, Kate" I respond, confident that she will comply She stand there frowning in silence, before rolling her eyes "You're disgusting" she says, while pulling off her tshirt quickly, and throwing it to the side. I stand there in awe, stunned at the sight of her sexy tits, and before I know it, she has her panties off and thrown to the side "Happy?"

"How about you stay like that for a few hours" I grin "Ugh, you are so freaking annoying" "Turn around" I demand She turns around immediately, ...

It instantly gets harder and harder before it's at it's final form. I place my hand on the back of her head and push it forward slightly, my dick goes into her mouth and she struggles for a second, but I hold her head in place. She starts to move her head back and forth on my dick, but doesn't go very deep down the shaft. "Wow, your pretty good at this" I say sarcastically It doesn't take long before I bust my load into her mouth, she holds it in her mouth for a moment, before I tell her to swallow it. She gulps it slowly and makes a sour face "That was great" I reassure her "No it wasn't" "For me it was" I chuckle slightly, then pull up my shorts and boxers "Can I get changed?" Kate asks "Nah, maybe later" I say in a cocky tone "I have to go shower" she says in a soft voice, before turning around and walking away. I slap her ass as she walks away, with a huge grin on my face "Wow, this is gonna be a great 2 weeks" I say to myself, and I walk into the kitchen to get a glass of water ...
