You have no other choice.

"Don't make me ask a second time. Suck it."

Jake's cock is framed perfectly between his legs. It's not even hard yet but it looks to be as long as your forearm and just as thick. You have no doubt that he used some of the same tech wizardry that turned you into what you are now on himself. Now, your only real experience handling a dick is from back when you had your own. That feels like an century ago right now. Besides, it's a little different when it belongs to someone else and that someone wants you to shove it down your throat. But... It's not like you have another option, right?

You get up on your knees and position yourself right in front of him. You wrap a dainty hand around his shaft and lift it up. You start to stroke him slowly.
He takes a pull from his drink and says "Good start. Do you actually know what your doing here?"
You meekly reply "Well, I had one of my own for, like, my whole life. And I know stuff from porn or whatever."
He smirks "Oh, I bet you do."
You have some colourful replies you could say to that but it's probably a bad idea to talk back like that. Despite you literally having him by the balls right now, you are not in control right now.
"Alright. Keep going. Show me what you know." He says.

He's fully hard now. You take a deep breath and dive right in. You start with the tip, the salty taste of his pre-cum feeling strange in your mouth.
Jake's hand caresses your shaved head. "God, I can't wait till your hair grows in. I just love something to grab onto."
You start to go faster, your head bobbing up and down on his cock, getting deeper with every passing second. The strange part is, you feel like you should be gagging right now and yet you feel perfectly fine. No doubt, they removed your gag reflex during your transformation.
What's even stranger is that this is so easy for you.

Jake moans. "Fuck... I thought I would have to make you **** on my dick but you are a natural."
"Look up at me. Don't stop. Just... Look me in the eyes."
You follow his command without question, his strange charm running through your body. You stare into his sharp blue eyes, never once taking his dick out of your mouth. "Oh my god... I'm gonna cum!"
You can feel it start to pulse in your mouth, inches away from climax. You try to take it out of your mouth but Jake pushes your head down onto his shaft, growling out the single order "Swallow!"
Then, it explodes in your mouth, shooting gobs of white-hot cum right down your throat. You try in vain to pull your head off of it but nothing you do seems to affect your body until the last shot of jizz is deposited in your stomach.

You pull your head off of the cock, desperately gasping for air. "How was that?" you say to Jake between breaths.
He's knocking back the rest of his drink, saying "God damn, I haven't had a blowjob like that in years!"
He pats the side of your face. "I mean, don't get me wrong, you still have a lot to learn. For example..." He points down at his junk. It's slick with your spit and a little cum is dripping from the tip. "You didn't clean me off. So... Do it."
Damn him. He keeps using his command voice on you. To remind you of your place, you figure. Because of that command, you're licking up every last drop of cum off of Jake's cock. It almost feels... satisfying to do it. Your head goes a bit fuzzy whenever he commands you and the part of your brain that's still you is disgusted with itself.
He says "Better." when you finish and it's like you're popping out of a trance. As your head clears, he shoves you out of the way and stands up. He stretches himself out and says "I think that was a very good first lesson, don't you?"
You wipe your mouth and sneer up at him "What do you mean?"
"This is your first duty as my Live-In Girl. You will be required to give me at least two blowjobs a day. One when I wake up in the morning and one right before I go to sleep. If you can manage that well enough maybe I'll end up moving you up to the trickier stuff."
"Like what?" You ask.
"You'll see."

Then he walks off to the bedroom, leaving you to sleep on the couch.
That is how your first day as Jake's Live-In Lover ends. You suspect that it's only going to get more difficult from here. Which is saying a lot considering all that has happened to you recently.

But hey...
At least you're not homeless, right?
