Your sister is kind of a loner, but one day she comes to you asking for help getting into a sorority. You’re a little surprised but you love your sister so you want to help. She says the sorority is having a party for everyone who wants to join but they have insisted that everyone brings a boyfriend. Your sister doesn’t have a boyfriend so shes asking you to come to the party with her and pose as her boyfriend. At first you’re not sure and wonder what if someone recognizes you as her brother, and what if they expect you guys to be all flirty or kissing or whatever? She ensures you that you will just be hanging out at the party and thats all. You agree because you really want to help your sister, she seems like she’s so excited you don’t want to let her down. You guys get to the party and everything seems fine, its actually a little boring and you are both confused as to why everyone had to bring their boyfriend. Then they call for everyone’s attention and say that they want everyone to start giving their boyfriend a hand job… ok this is super weird and you guys were not prepared to do that kind of stuff together… your sister pulls you aside to discuss in private if you feel ok doing this. You end up agreeing because you just really want to help. After a few minutes of this they tell everyone to stop. You both think its over, but then they say to move on to blowjobs… this is a little much. The 2 of you discuss and agree that since you’ve already gone this far might as well just do it and get it over with. Your sister starts sucking your cock and after a few minutes they tell you all to stop again. Thank god! It’s over!! Except its not over. They tell you all to move on to riding your boyfriends. Ok now this is way too much!! Your sister assures you that you guys don’t have to do this, but you both agree to just do it and get it over with. A few minutes into your sister riding you the sorority girls confess that they know you 2 are siblings and that this was all an elaborate hazing prank. Your sister is pissed and tells them they are evil and that there must be something really wrong with them. She says you guys are leaving, but they have been recording the 2 of you and threaten to show everyone on campus if you guys don’t finish. With no other choice your sister rides you until you creampie her right in front of everyone, and even after you cum they say you have to keep going for a couple minutes to shove the cum in even deeper. After you guys are done your sister tells them off and apologizes to you and the 2 of you leave.
