It’s the week of Halloween and you’re preparing for the big Halloween party that happens every year, all of your neighbors, friends, and family go to it. You and your stepsister have a playful banter back-and-forth about who is worse at Halloween. She’s very overly confident about her costumes and your lack of them, so she suggests the two of you make a bet. Each of you will bring a costume to the party for the other one to wear, and no matter what the costume is both of you HAVE to wear it. Whoever can wear the costume for the longest at the party that night, wins the bet. She obviously has something in mind that she thinks is going to really humiliate you, but she doesn’t realize you have something in mind for her as well… Whoever loses has to do whatever the other one wants for a full 24 hours. She starts listing off manual labor, chores, all types of terrible things that she wants you to do for her. She really doesn’t think that there is a single chance that you might win this bet. She makes the two of you swear to follow through, no matter what!
The night of the party comes and she is so excited to give you your costume. She’s way too confident. The two of you exchange costumes and agree to go get changed in separate bathrooms and meet back in the living room where the big party is. Pretty much everyone that we know and care about is there that night.
She gives you a super cheesy snow white costume, she even brought a wig for you to wear. You really don’t wanna wear a dress and a wig all night, because it’s simply impractical and uncomfortable, but there’s no way that you’re gonna lose this bet. Your stepsister comes out, wrapped in her big coat and absolutely furious with you. She says that she has the costume on under her coat, but she never in a million years would’ve thought that you were gonna bring her such a slutty costume!!! She’s yelling at you and on the verge of tears, but she takes off the coat because she desperately doesn’t want to lose this bet to you. People start looking at her, nobody at this party dresses like this for Halloween. She looks absolutely ridiculous in this skin tight, barely-there kitty costume. She freaks out. Your stepsister runs out of the party and locks herself in the bathroom upstairs.
Now, you knew that this would be humiliating, but that was the whole point, wasn’t it? You’re excited that you’ve won the bet, but you feel really bad that she was actually crying. You go and knock on the door until she finally lets you in. She has tears streaming down her face, she is so terribly embarrassed that everybody saw her wearing something so outrageous. She never expected you to bring a costume like this, she thought you were going to bring something funny, not slutty! You actually feel really guilty and you do everything to try and cheer her up, you tell her how good she looks, and how she was the hottest girl at the party! You tell her that no one was looking at her because she looked bad, they were just in awe of how sexy she looked. She wiped her tears and starts acting bashful. The mood shifts. She fishes for more compliments and starts to show off a bit for you. You can’t help but get turned on. Her teasing gets out of hand, but the two of you are so caught up in this moment. Everything feels so intimate and before you can fully register what’s happening… she’s on her knees infront of you. Things get hot and heavy. She begs you to fuck her. She spreads herself and shows you how wet her pussy is because of you. You fuck her right there on the bathroom floor. She climbs on top of you and rides you until the two of you cum at the same time. Lost in the moment, you don’t realize how loud the two of you were but reality hits when there’s someone knocking at the door… you just came inside of your stepsister at a huge party that everyone you know is at. Happy Halloween!
