Ivy's fleshly Aunt (a very powerful witch) stayed over for a few days recently and decided that Ivy wasn't really using her powers effectively enough when it came to asserting her authority and dominance over her stepbrother. She therefore, cast a hex which she thought would make the relationship develop along better lines for Ivy, and which would let the stupid muggle stepbrother understand his place in the family. She communicates this by letter to Ivy, but mischievously leaves out the key details of her hex. Ivy will discover this in due course. Namely... At totally random occasions the hex will cause Ivy's stepbrother to spontaneously shrink to the size of a grain of sand and fly through the air at great speed until he lands with splat, spread-eagled on her nipple tip....then the next random time....on her clit. Nipple/clit....nipple/clit....this becomes the hex's established pattern obviously designed by her Aunt to add a little variety. It's a random and repetitive hex, so initially, Ivy does not know 'when' the hex will be invoked, but....she quickly establishes the hex's pattern in terms of 'where' her stepbrother will be landing based on the alternating nature of the pattern...nipple/clit....nipple/clit...etc...so that bit she can predict!! Ivy initially objects to this degrading treatment of her stepbrother, and is concerned for him enduring these humiliating ordeals, which seem to last 24 hours at a time before he's restored to his normal life. Her conflicted state rapidly wanes however, because the hex is designed to render Ivy blissful pleasure, leaving her little room left to worry about her stepbrother's ordeals, or how the hex starts to effect HIS life going forward.
