(This was originally filmed as a custom video) Your sister walks into your room looking very embarrassed, clutching a robe around her to hide the ridiculous outfit you've made her put on! She tells you she can't believe that this is what you wanted to waste your favour from winning the bet on, but just to get it over with before your mom gets home in 10 mins. She reluctantly drops the robe and lets you see her in the tiny skimpy outfit you selected; complaining about how weird and gross this is as she turns and lets you admire her. You make her come closer and sit before her, looking up at her as she grimaces and tries to ignore you. She asks if you're trying to humiliate her, and you tell her yes - and you even make her do the 'floss' dance just to drive the point home! After you finish laughing you tell her to get on the bed, and you make sure she sits with her legs open so you get a great view. Your sister complains about the backwards g string you've made her wear; saying it's so small that it's basically like she's not wearing anything - you can totally see her pussy! She pulls the string to the side to prove how useless it is, then sarcastically asks if you're going to ask her to finger herself now. You quickly say yes, and she tells you that was way too fast a response! She considers it for a moment, then steels herself and starts slowly playing with her clit before sliding two fingers inside and starting to fuck herself with her hand. She accuses you of being perverted as you watch her, and asks if this is what you think about when you beat off at night. She says she can see your boner in your shorts, and as she keeps fingering herself you can see her considering... Suddenly she stops playing with herself and tells you that this is going to be a one time thing... but to get your cock out. You quickly pull down your shorts and your sister starts stroking your cock, looking like she's enjoying it even as she continues complaining and accusing you of being a weirdo for liking this. After a few minutes of stroking your cock she suddenly pushes you down onto the bed and starts sloppily sucking you off! You're amazed but keep quiet so as not to put her off, and your sister continues to give you a very wet, sloppy, gagging blowjob as she looks at you intensely. You try your hardest to make it last but eventually you can't hold it anymore and unleash a huge load down her throat, making her gag and twitch in surprise as she struggles reluctantly to swallow it! As soon as you're done she seems to realise how crazy that all just was, and she quickly runs from the room, saying that you guys are definitely even now!!
