(This was originally filmed as a custom video) Fiona has something she needs to get off her chest... For some months now, she has been helping out her brother with a very tricky problem. See, her older brother has a real thing for barely legal age girls, who are obviously way too young for him! Fiona is worried that without her help he's going to end up getting himself into trouble, so being the good sister she is, she allows her brother to take out all his urges on her instead. Whenever he gets excited over a hot young 18 year old, she takes him aside and encourages him to imagine she's that girl instead... and to do whatever he wants to do to her. Fiona reminisces about how this all started, with him getting hard over a girl in a movie, and Fiona deciding to stroke his cock to give him some relief... She describes how she found herself starting to enjoy it, and how the next time he got excited, at a party, she ended up first secretly sucking him off in the bathroom, and then even fucking him on the bathroom floor, while the party continued outside! Fiona says it's okay if you're judging her, she understands... though she says if you've never tried doing anything sexual with your own brother or sister, you can't possibly know how amazingly dirty and addictive it feels! She walks you through several more memories of times with her brother, where she would act all young and ditzy to excite him, and would let him sneak into her room very early every morning, so he could start his day by emptying his balls into her... Fiona admits that though this all started as a way to help her brother with his issues, she's found that now she's addicted to fucking him, even if she has to pretend to be a silly 18 year old to do it!
