The next morning Arthur woke up to his head rising and falling, realizing the pillows he was asleep on was his sister's massive breasts, he sat up. She too began to wake up and smiled, kissing him on the lips. It wasn't long before the two of them were having a morning session, with him pounding hard at his sister's pussy. He was glad his changes yesterday were not just a dream. He came twice that morning into Zoey's hungry pussy.
Zoey kissed him and got dressed from the waist down, ducking through their doorway in order to make some breakfast for herself. Arthur smiled, deciding to have some fun today, and pulled out the Dictaphone.
"This change can only be reversed by me, and Zoey cannot prevent me from stopping her or by proxy. When Zoey was in the womb, a doctor created a "Goddess" gene and injected Zoey with it. Upon entering puberty, the gene became active, and Zoey has near omnipotent abilites. Zoey is aware of her powers, and loves it. She cannot control her own size, but she can alter the size of others. She is growing at a rate of a foot a day, and her breasts are growing a half cup size a day until I feel she is big enough. The only things she is unaware of is the Dictaphone and the changes made to her. She is still obsessed with me, and hopelessly in love with me."
He smiled, letting go of the record button and the Dictaphone sparked as Zoey moaned downstairs, as her body began to grow and power flooded her every cell. She grew...and grew...and grew. Soon Arthur could feel the house shake and shift as it....also grew! Soon the door opened, and his 30 foot sister walked through....looking like a goddess. Every flaw or imperfection on her body was erased and she was...absolutely perfect. Zoey smiled as her clothes vanished off her body exposing her massive R cup breasts, capped with nipples perfectly sized and areola that were not too spread but not to thin either.
"Mmmm sorry my love, I had to go take care of the doctor who helped me become...a goddess. You see she was about to inject a few more children with the gene and I couldn't have that"
You looked worried for a second, scared you made you sister a psycho with all that power, and she giggled
"Oh you, you know me! I just made her forget how to make it and erased all research from existence, silly. You made me promise never to hurt anyone in exchange for having you for all eternity."
You then grunt as your body expands to her size, and she lowers her pussy on your cock. She smiles at you, as your eyes roll back, feeling pleasure beyond what you had ever felt before
"mmmm my brother...my lover....ohhh....go...I mean.....Me!"
She moaned, bouncing up and down on your cock, kissing you on the lips and letting her massive tits pile up on your chest. You could feel your cock expanding inside her as she made it even bigger for her own pleasure, so were your balls as you could feel grape fruit sized orbs on your thighs.
"mmm... I dunno bro... do you deserve to cum inside your goddess? Do you deserve to fill your goddess sister with your seed? Maybe I could let you be me for a day...or maybe turn you into my bra and keep you on me all day long.... mmmm so many possibilities with these powers of mine. Maybe I could make you irresistible to all girls...or make women the dominant sex on the planet....or turn them all into giantess... but nah.... I wanna have fun with you Arthur. I love you so much!"
You cried out as she had her orgasm, you felt it as well, surging through your body and the floodgates opened as you blasted your goddess sister's womb with your seed. Due to the size of your balls, your cum sprayed like a hose instead of small quick bursts. When you finished cumming, you felt your body shrinking back to its normal size and Zoey picked you up with one hand, Kissing your whole face.
"mmm This goddess gene that doctor gave me before I was born is amazing. I can't wait to see how big I end up. Sucks I cant just grow myself to planet size and have sex with you then. Or maybe you push the earth inside my pussy and make me pregnant with the planet... nnngh.... These powers are amazing! I love them so much!"
