(This was originally filmed as a custom video) You're hanging out on the bed with your sister when she starts complaining about being bored. You try to suggest a few things you could do together but she shoots them all down, saying she wants to do something more interesting. She brings up a game she saw in a movie and says it might be fun to play, but warns you that it's a little unusual... She explains that it's a guessing game, where she would put on a blindfold and you would put random objects into her mouth, for her to guess what they are! You agree and let her guess a few different objects from around the house, which she manages without too much trouble. She then says that in the movie they took it a bit further, but again warns you it's a little strange... She describes how they would get a few different sex toys, and try to identify those in their mouths! She tells you not to feel awkward about it, but she has some toys in her bedroom, if you would be up for trying that... You're a little surprised but say sure, why not, so she puts her blindfold back on and you begin putting a few different dildos into her mouth for her to identify. It's turning you on quite a bit watching her sucking each dildo to figure out which one it is, and when it comes to the moment where you would put a realistic dildo into her mouth, a crazy idea seizes you and you quickly pull out your hard cock and put that into her mouth instead! She's confused, taking her time feeling it with her tongue and trying to figure out which toy it is, but she just can't do it. She goes to remove the blindfold and you quickly stuff your cock back into your pants and hold the dildo in front of you, just quick enough that you get away with it! Your sister accepts that she must have just not been able to identify that one properly, and then decides to tell you about the third and final part of the game she saw. She says it's pretty kinky, but if you have an open mind it should be fun - she wants to try identifying the same toys again, but with her pussy this time! You're still rock hard in your pants so of course you agree straight away, and she puts the blindfold back on and bends over, pulling down her panties to give you access. You use all the toys on her again, and briefly consider using your cock again instead of the realistic dildo, but decide against it and instead slide the dildo into her pussy. She guesses which one it is straight away, and remarks on how odd it is that she could recognise it in her pussy when in her mouth it felt so different! You watch her thinking to herself for a moment, then she surprises you by asking if she could see your cock, as she wants to compare it to the dildo... Nervously you agree, and pull out your hard cock for her to examine. She holds the dildo up next to it and thinks to herself, and just as you're starting to panic she surprises you again by saying she's got another idea for how you can continue the game.... She wants you to strip off and lie down on the bed, then hold the dildo so that she can fuck it and pretend it's your real cock! She says she'll put the blindfold back on so it really feels like she's riding you, and says how dirty and hot it will feel pretending to fuck her brother - though of course it's fine, as she'll only be fucking the toy, not you! You lay back and hold the dildo over your crotch as she climbs on top of you, then as she pulls the blindfold down again you make a split second decision and pull the toy away, letting her slide down onto your erection instead. She groans in bliss and says how much more real it feels in this position, it really does feel like she's got your actual cock inside her! She begins riding you, getting more and more into the 'pretence' and talking about how filthy it would be to actually fuck her brother like this, instead of just pretending... At one point your cock slips out and you manage to grab the dildo and put it back in position just in time for her to remove her blindfold. She seems a little suspicious but wants to carry on, and you manage once again to take away the toy and get her to mount your cock instead. It's not long before she's cumming hard on your cock, and her pussy squeezing you feels so incredible that you can't help but orgasm at the same time as her. She realises as she's cumming that she can hear you moaning, and feel your seed flooding her pussy, so she pulls off the blindfold to find you buried deep inside her as cum begins to leak out of her pussy! She's exasperated and annoyed, though it seems like she's less annoyed about you tricking her than you cumming inside her! She angrily tells you that she's not on the pill, so you'd better hope she doesn't get pregnant, as she's super fertile right now!
