Ever since Ivory found out what a small penis her step-brother has, it’s all she can think about! She knows that nerds with small penises make good slaves. She knows how weak her socks make her step-brother, so she decides to manipulate him into being a slave for them. Every time he wants to cum to her socks, he will have to pay and buy her socks. First they will be $100, but every time he wants to cum he will have to pay another $100 extra! She knows his little dick gets no action and he has a strong fetish for smelly socks, so of course he will obey her! She knows sexless nerds are good at saving money and he still lives at home so he has plenty of money to spend. That combined with lack of sexual attention in his life makes him a prime candidate for a long time addiction to sending her money for his sock induced orgasms.
