*** PLEASE READ DESCRIPTION FIRST*** ***ALL SCENES IN PREVIEW ARE ONLY SCENES AND IN THAT ORDER*** You see a fuckmachine in the preview but i dont turn it on (I do grind and fuckmyself on the machine though).....I have a very preppy/bratty/ditzy girl vibe in the vid so keep that in mind......I say the words "fucked up" "what the fuck" "good boy" "good doggy" "pervert (calling you a pervert)" fairly often.*** ***PLOT*** Your sister wants to go out tonight but she already spent all her money so she asks you for some. She says she'll do anything and you tell her you want her to fuck the family dog. She freaks out calling you a perv and says no. The dog hears the two of you and comes into the bedroom with you two and your sister starts to freak out because the dog is staring at her. After staring at her she notices he has a huge erection and she freaks out again saying how huge it is and that even if she did fuck the dog theres no way she could fit it. You tell your sister you'll up the price to $100 if she does what you asked and she gives in. She gets on all fours trying to get the dog to mount her until he starts fucking her. While shes being fucked she says often how "fucked up this is" and at times calls you a pervert for watching and if you get off to this kinda thing. The dog fucks her in multiple different views until she gets a huge creampie inside her pussy. In the end she tells you she secretly loved being fucked by the family dog and that she cant wait again until next time
