(This was originally filmed as a custom video, and the perspective moves back and forth between the brother and his friend) You're hanging out in your room with one of your friends, when your sister barges in and begins immediately bothering the two of you, wanting to know what you're up to and if you're going out to meet girls. You make fun of your sister, saying that she's so inexperienced that she wouldn't know the first thing about what you get up to with girls.Your sister gets defensive and starts trying to convince you both that she's actually had loads of experience, and that when she was in high school she even had a reputation as a slut, which you know is a lie. You decide to see how far she's willing to go to convince you of this, so you say that if she's done so much stuff with guys before then it will be no problem for her to kiss your friend. She protests for a second, feeling awkward, but then gives your friend a very quick peck on the lips. You tell her that wasn't what you meant, hasn't she ever kissed someone properly before? She insists that she has, and kisses your friend again, this time making out with him properly. She seems to expect that you'll believe her now but instead you tell her that surely if she's such an experienced slut she'll have no problem with taking her top off right now. She awkwardly peels off her top and sits in front of you in her bra, but then you tell her you meant the bra as well... She steels herself to do it, blabbering about how she does this sort of thing all the time so it's no big deal, then takes off her bra as well. You tell her she looks good, and she seems thrilled - but then quickly backtracks, pretending to be nonchalant about it and saying that guys compliment her all the time. You tell her that you've made your friend hard, taking her hand and placing it on your friend's crotch, and your sister is clearly shocked to feel his erection through his jeans. You tell her that any experienced slut would know better than to get a guy hard and then not take care of him, and she nervously agrees, taking out his cock and agreeing to blow him. You watch her giving your friend the worst blowjob you've ever seen, and start giving her some pointers and directions. She's irritated at first by your suggestions, but then begins to do what you're telling her, visibly improving under your direction. She realises that you've started stroking your cock as she sucks off your friend, and questions what's going on, but you remind her that two cocks should be no trouble for her, as she's so experienced and slutty. You step up next to your friend and tell your sister to kiss your cock, which she does nervously, thinking that a kiss will be no big deal. As she kisses the head of your cock you push your sister's head down until you're filling her throat, and she gags and splutters; pulling back and demanding to know what you think you're doing. You say sorry, it was just a deep throat, surely she's done loads of those? Your sister tells you sure, she's an expert at deep throats, she was just surprised, that's all. She begins to suck you both off, attempting to convince you of her deep throat skills, until you tell her that your friend is ready to fuck her now. She agrees nervously, asking if you're going to leave the room so she can do it, but you tell her you'll be staying right here. Your friend positions himself on the floor underneath her and you tell your sister to go ahead and ride your friend in reverse cowgirl. Your sister seems to find it quite distracting having you still right in front of her with your cock in her face, but as she rides your friend she relaxes a bit, enjoying the position, and eventually starting to suck your cock again as she bounces up and down on your buddy's dick. She's clearly getting more and more turned on by the situation, but keeps stopping to remark on how dirty and wrong it all is. Your friend gets close to cumming, so jumps up and shoots his load all over her face. Your sister gets covered in cum and smears it all over herself, turned on but shocked by how the situation has progressed. As she's sitting there all covered in your friend's jizz, you tell her that there's one more thing she needs to do to prove to you that she really is a slut like she claimed, and you make her lie down on her back. You get on top of her and slide your cock into her wet pussy as she weakly protests that it's wrong for you to cross this line, and besides she's all messy with cum - but you tell her not to worry about it, and as you pound her she relaxes and starts to enjoy the filthiness of it; telling you to use her like a slut and to make her cum on your cock. You cum together, filling your sister's pussy with your seed. Then, looking rather dazed, she stands up and - still covered in and leaking spunk - grabs her clothes and says she has to go, but maybe you should do this again sometime!
