Not at all liking this, seeing my sister turn into a evil version of myself!? No proper hero could tolerate such blashemy, as I transform as well to get into the mood. Wiggling my butt at her before forming my sword out of thin air to gran it in midair in return, dancing and shaking my booty in turn. Both of us finishing at the same time, to only see one of my harem get hit with a spell! Such a meanie! Planning on finishing this off quickly and with overwhelming power!<br/><br/>Thrusting my paws at the amulet in my belly button, charging it up for my ultimate attack! The energy eventually shooting out in a pink sparkly beam to hit my evil sister dead on! Laughing out a adorable foxy laugh as realization hits her face, my magical power infiltrating her brain and granting me control of her sexuality and ability to cum! Something that she too is well aware of.<strong>"Nyhahahaha, you belong to me now sister! Now, have painful cums over and over until you pass out!"</strong>The command final as I wait for her to double over, holding onto her own crotch as she has those painful cums.
