"You've always been bossing me around, Tanya. Now it's my turn." Todd laughed.
Tanya tried to speak but Todd's previous order made her mute.
"Sit at my feet."
Tanya slid off her chair and kneeled at her younger brother's feet.
"I think I'm going to give you a gift. You're always complaining about the size of your boobs and the plan I've made for you needs you to have massive ones..."
Tanya was confused. She did want bigger boobs- all the girls in her class made fun of her in the changing rooms. But Todd's plan didn't sound good at all.
Todd tapped the wand on his sister's boobs and the grew to the size of huge watermelons. They ripped through the girl's stupid geeky shirt and the enlarged pink nipples stood erect.
"You love your new boobies, don't you slave? Play with them now."
Tanya's hands reached up and juggled with her mega boobies.
"Now stop. Stand up and strip."
She did just that, standing there totally naked. Todd locked her bedroom door.
"I think I should tell you my plan. You see, I've been running low on money for a while now. I've heard some high-end sluts earn some big bucks. So, I'm going to make you the most desireable, sexy bimbo slut then sell your skills. What do you think?"
Obviously, Tanya couldn't speak. She shook her head violently to indicate her distaste but Todd just laughed.
He continued in transforming his ugly, geeky older sister into a seductive sex slave. He made her short brown hair long, curly and blonde. He made her very thin, with a huge ass. Todd made sure to make her permanently aroused, with her juices dripping to the floor at all times. Tanya had to stand and endure this.
"You're still a virgin, aren't you sis?"
Tanya blushed and nodded. At nearly eighteen, her peers considered her virginity a sin.
"Then your holes are tight. Oh, well."
Todd took her headphones and tapped them with his wand, transforming them into a twelve inch dildo.
"This is gonna hurt. Too bad!"
Todd pushed the dildo up into Tanya's tight entrance. She was forced into silence but her face conveyed her intense pain. Once it was finally done, she stood there panting with tears running down her face.
'Next thing is your ass. This might hurt more, but get used to it."
Todd turned another item into a thick, long buttplug that would fill up his sister's ass. He rammed it into her, ignoring her shaking and torrent of tears.
Finally it was done and Tanya stood there silently sobbing and in terrible pain.
"You look the part and you're all widened. But you're still smart and unwilling. Urgh, you're so much effort Tanya!"
Meanwhile, Tanya was in the most pain she'd ever suffered, psychially and emotionally. Her ass and pussy ACHED and she felt unpleasantly full, yet juices still ran down her legs into the puddle pooling on the floor. She was being unwillingly changed into a sex slave by her younger brother!
"Your mind feels so empty. Your IQ is pretty much zero. All you can think of is sex. You crave it. You want cocks in every hole. The dildo and buttplug feel amazing. You can speak, but all you can say is 'do you want me, sir?', 'fill me up with your delicious cum!' and 'send the paycheck to Mr Todd Rogers, sir'. If the man you're pleasing wants you to call him something else, you must obey him. You giggle constantly."
Tanya felt everything she knew slip away. She giggled and felt the pain transform into arousal.
"You obey me and whoever pays for you. You'll stay this way forever. Or at least, until I tell you. Oh yeah, you're going to move out and live in an apartment downtown."
Tanya had been transformed and Todd was about to get rich...
