Your older sister is busy texting away on her phone, and tries to ignore you when you tell her that you've got something she needs to see. She tells you to just send it to her and she'll look later, but you insist that she looks at it right now. She sighs grumpily but looks at your phone - only to see a video you secretly took of her fucking her boyfriend! She's shocked and furious that you recorded her, but you quickly remind her that you both know she's been banned from having any guys over to your parents house, and if they saw this video she'd be in deep trouble.... Your sister quickly catches on to the fact that you want something for her, and angrily tells you to spit it out. Do you want her to do your chores for a while? You say no, you want something different. You want a look at her pussy! She's grossed out and refuses, but you remind her that you can very easily send the video on to her parents, and eventually she relents - though not without lots of complaining and telling you what a weird little pervert you are! After you've had a look for a moment she asks you to delete the video, but you inform her that you've decided that's not enough to keep you from sending it to your parents. She's going to have to let you touch it! She's furious that you've gone back on your word, but doesn't really have much choice if she doesn't want to get in trouble... So she lets you touch her pussy as she squirms awkwardly! Of course, you're not going to stop her, and you inform her that the final thing she'll need to do is to let you fuck her. Although she protests, she realises again that she's stuck, and so she finds herself agreeing! As you begin to slide your cock into her tight hole she shuts her eyes and complains about how weird and unnatural it is, but as you start to thrust hard inside her she can't stop herself from enjoying the sensation, and she gets more and more into it until she orgasms on your cock! She can't believe that she actually just came on her own brother's dick, but you don't give her any time to dwell on it, instead informing her that it's your turn now, and thrusting hard and fast until you flood her pussy with cum - ignoring her protestations about not being on any birth control!!
