"Oh wow!" Brittany grinned as Karl unloaded all over her, "It's so much babe!"
"Well I thought it would be good to do a little something special for your send off."
"Send off?" Brittany was confused, "But I'm not-"
Then, Brett awoke. He was looking up at Karl the Magnificent, the honest to God wizard he'd found. He'd asked for Karl to teach him magic. Karl said being his apprentice came with a heavy price. Brett said he'd do anything, and then-
Brett was holding Karl's dick. There was cum all over it. There was something sticky all over Brett. Some of it was in his mouth. It was salty. Some of it was running down his chin onto his- BREASTS?!
"Welcome back Brett." Karl smirked.
"What the FUCK?!" Brett whined in a voice that wasn't his, "You turned me into a woman and made me-"
"Just wait a second. Some of the memories of the past year ought to be merging in with yours right about now. That should make all this - well I won't say easier, but at least more familiar."
"The past YEAR?!" Brett balked. Then he started to remember. Well, not remember really. It was more... impressions than recollections.
He'd been Brittany, and she'd been devoted to Karl. She loved sucking Karl off and getting his cum all over her, and knowing that made Brett shiver with an involuntary delight. And of course Brittany hadn't just sucked Karl's dick.
She'd really, really loved getting fucked. It made Brett horny just thinking about it.
"Ugh." Brett felt so dirty with all the cum all over his female body, but also weirdly satisfied about it. "You made me your girlfriend for a year?"
"Woah, woah, woah! Brittany was more live-in sex pet-slash-housekeeper than anything like a girlfriend." Karl said.
Brett vaguely remembered doing a lot of cooking and cleaning too. In a weird way he felt relieved. He'd paid the wizard's price, but barely remembered any of it. It was almost like someone else had paid it. "Fine, whatever. So I'm paid up then? You'll train me to be your apprentice?"
"That was the bargain." Karl nodded.
"Great!" Brett was excited despite it all, "Turn me back into a guy and we can get started!"
"I'm not turning you back." Karl answered matter-of-factly. "You're my apprentice. You're going to have to learn to turn yourself back. Don't worry, I'm actually a pretty good teacher. It probably won't take more than ten, fifteen years for you to be able to cast a spell like that."
"Ten-" Brett's jaw dropped. He was going to be stuck as a woman for a decade!?
"Oh and you should know-" Karl smirked, "Your duties as my apprentice include all the things Brittany used to do. I'll give you a few hours to settle in, but you are responsible for dinner later."
With a wave of his hands, Karl disappeared in a puff of smoke.
Brett rushed to shower, thinking over just what the hell he'd gotten himself into. It was all worth it to learn magic, right?
After he showered he was feeling stressed and... still horny. No more memories of Brittany came to him, but her impression that her orgasms were fucking incredible was pretty damn strong. Masturbation was classic stress relief, right?
Forming his own memories now, Brett did feel pretty relieved to discover fingering his pussy really did feel awesome, although... Brittany had left him with an impression that getting fucked felt even better...
Maybe being Karl's apprentice/sexpet/housekeeper wouldn't be so bad...
