Custom: Giantess Step Sis Goddess

Description: Custom: you, my step-brother, are standing in my room. gawking at me as i do mundane things around my room in my underwear. i'm unaware you're standing there watching me. i eventually see you, and angrily approach and get eye level with you. i tell you that i know about your sexual fantasies about me, and how you wish you could fuck me, but it will never happen. ever! i tease you with my body, telling you that you will never ever get to have me. i shoo you out of my room. you created a size changing machine, and shrunk yourself. you go back to my room and watch me. i walk around in nothing but an oversized t-shirt, once again unaware of your presence. i even stand over you, and you get a good look under my shirt and at my ass and pussy. i bend over a few times and you get an eye full of my ass. i remove my shirt, and throw it in your direction. that's when i spot you. i can't process what i'm seeing. what did you do? how? you explain your little size changing machine project and how you shrunk yourself to spy on me. i'm appalled. i pace back and forth wondering what to do, thinking out loud. it hits me that you're under my mercy, and that no one knows that you're small. i take great pleasure in this and go through various ideas of what to do with you before deciding that i will use you for my sexual pleasure. i start to finger myself while sizing you up, deciding if you'll fit inside of me. i get turned on while i do this, and crawl to you and put my face very very close. i tell you that i'm lustful and will use you to fulfill my desires. i take you to my bed. you're right at my pussy, with my face still in view. i describe how i'm going to use your machine to make myself huge, larger than life, a giant! i will make the entire little city worship my as a goddess. i will use buildings as dildos, and smash buildings with my ass. i get turned on again and start fingering myself once more, describing how i will have the entire universe worship my huge pussy and ass. once i finish, i tell you that you're no longer worth anything to me, and put you inside of me.
