Brook Logan "Don't Tell Dad"

Brook is looking forward to finally going out on her first hen do, she asks you if her package arrived and you tell her it did. As her step brother you thought it would be OK to open the package but you were very surprised at what you found. Brook has ordered herself a new dildo, she begs you not to tell her dad because he won't let her go to the hen do if he realises she isn't an innocent little girl anymore. You decide to make a deal with her and make the most out of the situation, you have always had the hots for her so you tell her that if she uses the dildo in front of you right now and lets you wank too, you won't tell her dad what a naughty little slut she really is.
