You probably should have cleared your search history before lending your laptop to your sister... :P Now she knows what a dirty fucker you really are! So much dirty porn...your sister teases you and tells you she watched it all. You're embarrassed at the confrontation but your sister tells you she enjoyed it, she actually kind of likes the thought of the brother being a dirty fucker, jerking his cock to dirty porn videos in the room right next door to her. She tells you that she's dirty and loves to watch porn too - she asks you if you enjoy taboo brother/sister porn, that's the sort of fucked up porn that reeeeally gets her off! Ever since she found your dirty vids, she hasn't been able to stop thinking about being dirty with you for real. She tells you that if you don't fuck her then she'll tell your parents about all the dirty porn she found...and you'd get in sooooo much trouble, wouldn't you? :P She wants to be so bad and dirty with her own brother! She wants you to jerk off together, she wants to fuck you and she wants to watch dirty, filthy porn with you. She's especially excited to show you all her favourite brother/sister porn videos...she just knows you're going to enjoy them as much as she does... :P
