(This was originally filmed as a custom video) Your big sister barges into your room looking very stressed out - she's completely wrecked your dad's car in a parking accident and is terrified of what your dad will do when he finds out! She's really freaking out and demands that you help her - that's what brothers are for, right? She says she's willing to do anything! You say well if she'll do anything, there is something she could do to convince you to help her, but she might not like it... You want to fuck her up the arse and then cum on her face! At first she thinks you're joking and then is horrified to realise you're being serious - she asks is there anything else she could do instead?? But you tell her nope, if she wants your help that's what she has to do. She offers to suck your cock instead, hoping that maybe she'll be able to make you cum that way and she won't have to let you fuck her ass, and you say well we can start with a blowjob... She complains loads at first as she sucks you off, talking about how wrong and dirty it is to have her little brother's cock in her mouth, but you make her shut up and show you her skills. She gets super messy and sloppy deepthroating your cock, desperately trying to make you cum, but it doesn't work and you tell her it's time to spread those cheeks! As you fuck her tight hole she talks constantly about how dirty and wrong this is, worrying about having her ass juice all over your cock, but you can tell she's starting to get into it as her words start getting filthier and filthier and she starts to moan more and more! You keep fucking her in the ass with regular breaks to make her deepthroat you and clean her ass off your cock, and she's surprised by how much she's enjoying it now, begging you not to tell your friends what a whore she is. Eventually she begs for your cum and you shoot your load all over her face - and she thanks you and tells you she'll be here for you to use whenever you want!
