Your sister comes into your room looking really upset, and tells you she's discovered that her boyfriend has been cheating on her for a year, with her best friend! She's furious and humiliated and you try to comfort her, before she tells you that she wants to do something to get back at them. She wants to make her boyfriend think that she's been cheating on him the whole time too, by sending him some pictures of her with another guy! The trouble is, she needs to send them quickly so that her boyfriend will believe that she had them ready - if she just goes out on the town looking for a guy to fuck and take pictures with, her boyfriend will guess that's what she did and won't believe her that she had them from before. Besides, she doesn't want to have to go and find a stranger to fuck... She says she knows it's a huge ask, but could you maybe help her take some pictures..? She says you don't have to do too much in them, they can just be like lingerie shots of her but with your hand or maybe your cock in them... Just so that her bf is convinced that she's been messing around behind his back too. You're understandly not keen on this idea, but your sister begs you, saying would you rather she went out to find a stranger?? You say no, of course not, and reluctantly agree to have your hands and your cock in the photos. Your sister is so grateful, and immediately strips down to her lacy red lingerie, getting you first to take some pictures of her on the bed, and then asking if she can just like, hold your cock, or maybe put it near her mouth as if she's going to suck it....You take some photos like that, trying not to think about how hot your sister looks, before she asks if maybe she could just suck it a bit, just for the photos? You want to be helpful so you say yes, and she starts sucking your cock.... You're feeling very weird by now but you can't help but get super turned on as your sister sucks and licks your cock while you take photos. You find it harder and harder to concentrate on the task of taking pictures, often ending up just enjoying the blowjob for a while until she reminds you to take pictures again... It's feeling so good that by the time your sister asks if you could maybe take it one step further and take some pictures with your cock in her pussy, you find yourself agreeing readily... Your sister bends over on the bed and peels down her panties, and you're surprised by how dripping wet her pussy is as you slide your cock in and begin to take some pictures! It's even harder to remember to take photos now, but your sister also seems distracted and isn't reminding you as much, instead moaning and breathing heavily as you begin to fuck her harder and harder... You're getting quite carried away when your sister suddenly stops you, and for a moment you worry that you've gone too far, but to your surprise your sister tells you that she's got an idea - her boyfriend always wanted to put it in her ass and she never let him, so if she had some photos with your cock in her ass that would be sure to really piss off her boyfriend! You can't believe this is happening as you slowly slide your cock into your sister's tight virgin asshole, and your sister seems to love it, saying she should have done this ages ago, it feels amazing! You quickly snap a few pictures and then focus on fucking your sister's ass, with your sister starting to furiously rub her clit as she pants and moans beneath you. It's not long before your sister cums, and you just about manage to hold onto your own orgasm, asking your sister if she's sure it's alright if you cum - you don't want things to feel weird between you... But your sister tells you to go ahead and cum, you deserve it after helping her out so much, and she begs you to cum all over her ass so you can take one last photo of her ass covered in cum to send to her dickhead boyfriend!
