Your little sister comes into your room looking rather upset, and wanting to hang out. You ask if she's still going out with her boyfriend tonight, and she tells you no, he broke up with her just now. You begin to comfort her but she tells you she's not that bummed about it, she wasn't really into him. Mostly she's just annoyed that they didn't last long enough to do anything, you know, sexually! She complains to you that she keeps dating these guys who break up with her after a few days or a couple of weeks, and she's stuck being a virgin! She's worried she's never going to lose her virginity, and the longer she waits the more stressed out and in her head she gets about it! She laments to you her lack of any male friends, saying if only she had a male best friend, he could just help her out one time, and then it would be less of an intimidating thing for her. You agree it's a shame that she only has female friends. Your sister then gets a sly look on her face, and to your horror suggests that YOU help her! You immediately try to shut her down, but she begs you to help her, saying it would only be one time, and you're supposed to want to look after her!! You tell her no, no way, she's your little sister, it would be totally wrong. It would be the i word! Besides, you have a girlfriend anyway, who you love. Your sister looks even more sly at the mention of your girlfriend, and horrifies you even more by pointedly asking what your girlfriend would think about all the messaging, and sexting, and exchanging of nudes you've been doing with girls online... You're furious at your sister for snooping and for using it against you like this, but she's got you trapped. You eventually, reluctantly, agree to help her this one time, on the condition that nobody ever finds out, and your girlfriend stays in the dark about your online activities. Your sister gleefully strips down, having a moment of doubt when she sees the size of your cock and wonders whether it will be too big for her first time; but she's extremely detirmined to lose her virginity, so she lays down and beckons you closer. You position your cock at her entrance but freak out a bit before you can put it in - this is your own sister! She's having none of it and reminds you of the awkward positition you're in, bossily demanding that you hurry up and take her virginity. You take a deep breath and slide your cock into her pussy, feeling the mix of shock and pleasure as you penetrate your sister. You try to tell her to shut up and stop talking so much, so you can concentrate (and try not to think about who it is you're fucking), but she chats away constantly, and in spite of this you're surprised to find yourself getting into it. You feel extremely guilty as you begin to enjoy yourself, but you can't deny how very intense it feels to be inside your own sister! Your sister cums hard on your cock, and you find yourself admitting to her that you didn't finish yet, but... Your sister immediately tells you to just get on with it and cum inside her, it's no big deal! You don't need any more encouragement and begin fucking her hard again, quickly flooding her pussy with cum as you wrestle with how wrong this all is! You know you shouldn't, but as you pull out you tell your sister that if she wants any more experience, you'd be happy to help out, after all...
