Your little sister has been borrowing your laptop, and when she returns it to you she sits down with a gleam in her eye, asking you if you remember that time years ago when you walked her through how important it is to delete your browser history frequently.... Your heart begins to race as you realise what she's alluding to, and you blurt out excuse after excuse as she lists off all the interesting videos she saw you've been watching! You try to convince her that you must have been hacked, you would never watch that kind of stuff, but your sister challenges you by slowly stripping off, saying that surely you'd tell her to stop, if it really wasn't you watching those videos... Surely you'd stop her and tell her to get out of your room, not watch frozen and staring as she gets naked and plays with her pussy right in front of you! You can't tear your eyes away, even as you weakly protest that it was a hacker, it wasn't you... But the growing tent in your pants only eggs her on! Soon you can't help it and you pull out your cock to stroke it, making your sister grin as she fingers herself, knowing she's won but keeping up the pretence of how of course it wasn't you, that would be so wrong, you would never think about your sister like that... You can't stop yourself from cumming as she watches, and she laughs and gets up, telling you to make sure you're more careful with your browser history in future, or she'll keep getting the wrong idea!
