This is my first time writing something like this. I enjoyed doing it, and I'd love to hear what you think -- but please be nice :-)

After the law was proposed, it passed shockingly quickly. Practically-guaranteed sex was a sure winner with a surprising number of people. It was a mere five days from when the Fairly Regulating Equitable Enjoyment and Under-Satisfaction Elimination (FREE USE) Act was introduced in the Senate until it was signed by the President.
Anyone could now sign up to be a publicly available toy, with pay from the government for every hour they spend servicing someone, plus a bonus for each person they serve.
I woke up, yawned, and threw on a bathrobe, joining my roommate Mike for coffee and breakfast. He was scrolling on his phone as he ate some toast.

“Morning, Sarah,” he said, sounding annoyed.

“What’s up?”

“That sexist act just got signed.” He sighed.

“Eh, I dunno—it’s not like it’s only women that can sign up. Plus, everyone has a choice as to whether to sign up. Plus, it’s on top of your basic income so there’s not even coercion!”

He looked up from his phone at me. “Oh come on, Sarah. You know what those politicians were thinking when they voted for it.” He paused, looking at me. “Wait, you seem almost…happy right now. Don’t tell me you think this is good?”

“Well…” I blushed, looking down slightly.“Wait, it’s even more than that, isn’t it?” he said, with a quite different look suddenly in his eyes.

“I don’t know what you mean,” I said, not convincing him any more than I was convincing myself. He raised a single eyebrow. I shifted in my chair, trying not to meet his eyes.

“Maybe I’m wrong. But I don’t think so,” he said firmly. He put his phone down on the table. His eyes looked… I can’t explain how, but predatory. I swallowed, and couldn’t stop myself from smiling slightly. Mike was hot, certainly, but, well… I’d always thought he was way too hot to be interested in me. He’d known me since long before my first dose of estrogen, not to mention bottom, and he’d never seemed interested. I’d idly fantasized about the things he could do to me, but he had an almost endless succession of girls way hotter than me coming in and out of the apartment, and… I blushed even more deeply.

“I thought so. But I still want to hear you say it.” He reached out and gently cupped my chin with his thumb and forefinger, lifting it to look him in the eyes.

A beat.

“Say it.” His tone changed. It was harder, firmer, more, well… commanding. I felt a sudden need between my legs.

“I … I think I want to sign up for the program,” I mumbled, trying but failing to look away, anywhere but those dark eyes staring directly into my soul.

“What was that? I didn’t hear you.”

“I want to sign up for the program. I want to be a free use slut,” I said, still looking him in the eyes, as if I physically couldn’t look away. I felt vulnerable, like the fluffy robe around me didn’t exist. I could tell he was undressing me with his eyes. Those gorgeous brownish reddish eyes.

He grinned. “Well, we’d better start getting you ready, hadn’t we?”

I was befuddled. “Ready?”

“For your proficiency exams, of course.”

“What exams?” I had only read the headlines, I didn’t know much more about the bill—no, law now.

He picked up his phone again, and started reading aloud. “Each prospective free use slut will undergo a mandatory 8-hour medical exam and two 8-hour sexual exams. During the medical exam, they’ll be vaccinated against every disease we have a name for and undergo a permanent, but reversible, contraceptive injection, which will also keep them constantly aroused. During the sexual exam, they’ll be tested for everything from deep throating, to anal, to pain tolerance. Overall scores will be displayed to their potential users. Sluts with higher scores will likely get more users, and so bigger bonuses.”

He looked at me again. “If you want to get lots of use, which I very much think a slut like you will…” he paused, eyes running down to my loosely-tied robe, then back to my face. I shifted in my seat. “…then you’ll need lots of practice for those exams. I’m happy to train you, under a few conditions.”

“What conditions?” I asked, barely able to contain my excitement, and barely pretending to care what the conditions actually were. He wanted to use me!!

“These will all apply for the next two weeks,” he started. “First, you’ll take vacation from work. Second, you’ll set your alarm 30 minutes earlier than mine and wake me with a blowjob every day. Third, you’ll keep yourself lubed, plugged with dildoes in your pussy and ass, and naked except for your panties. Fourth, you’ll stay on a pillow under my desk while I work, gently and slowly worshipping and warming my cock unless I tell you to stop. Fifth, you’ll call me Sir or Master at all times. Finally, you will obey all of my orders, unless you need to use your safeword, which will be ‘red’.”

My mouth fell open. I hadn’t known he was this kinky. I could smell how wet I was, and I was sure he could, too.

“Well?” he asked. “I agree, Master,” I said, untying my robe and slipping it off onto the chair below me.
