Your sister yells for you to come see her in her room. You can hear the palpable anger in her voice so you instantly go see what it is that she wants. As you walk in your laptop is sitting on the bed in front of her. "Care to explain what my porn is doing on your laptop?" she asks, turning your laptop towards you so that can you see the still image of one of her sex tapes clear. You can't believe she found that folder. The folder that contained each and every one of her porn videos that you were able to find. Your sister begins to berate you, saying that only a filthy pervert would have so much of his sister's porn on his laptop. "How often have you jerked your cock for me? How many times have you cum, how many loads have you shot out for your sister?" she asks. Then, she says that she wants to see for herself just how perverted you are. She wants to see how turned on you get by watching her porn. She plays the video, making teasing comments the whole time. By the time she stops playing it you are completely hard, something that does not go unnoticed by your sister. She wants you to now unzip your pants so she can see just how hard your cock is for her. You do what she wants. She then lifts up her shirt, teasing you, seeing if you can get even harder, even bigger for her. It's then that your sister leans forward and tells you something that absolutely shocks you, while also turning you on even more. "I'll let you in on a little secret. I think being a pervert runs in the family, because I'm just as big a pervert as you are". You can't believe it. Seeing your big, hard cock has her turned on! Knowing how filthy, how naughty, how it would be to fuck her own brother has her turned on! And she wants to fuck you! You can't believe it, you are finally going to get the real thing. Without any hesitation, the two of you begin fucking. Your sister's pussy is already sopping wet from how turned on she is by what is going on. You pound into her while she is beneath you in missionary position. This is the best sex either of you have ever had. The whole time she continues to dirty talk to you, tease you, making your cock throb even harder inside of her. She then tells you to lay down on the bed, so that she can ride you. You can't take your eyes off your sister as she bounces up and down on top off you. Her small, perky body looks absolutely amazing. Her tight, warm pussy feels better than anything you've ever felt before. And then, your sister is cumming on your cock as she continues to ride you. Then, she is telling you, demanding you to cum inside of her. She wants her brother's huge, warm load deep inside of her pussy.
