Kristi is your bitchy older sister who always seems to have it out for you. You can't ever seem to do anything right, she is always on your case about something! That sucks for you because today you weren't as careful as you usually are... You were in such a hurry to bust one out that you carelessly forgot to lock your bedroom door! That was your fatal mistake... Kristi came barging in to your room without knocking, like always, and caught you with your dick in your hand! She quickly snatches your phone before you could delete the evidence and now she knows your naughty little secret.... you were jerking off to fart porn! This couldn't be any worse, now your bitch sister has all the ammo she needs to make your life a living hell! Ofcourse, after experiencing what comes next, you would have preferred that she told your parents instead of the evil devious punishment she made you endure!
