[M4A] Two power bottom prompts

Hi there! I've been absolutely itching to do a slow-burn RP with a power bottom (gender doesn't matter)

My kinks include:

Older partners

Interspecies Relationships

Size Different

Power Bottoms (duh)

These are non-negotiable for me, however I can more than accommodate any kinks you may have as I'm not picky in that regard. My limits are anything illegal, and bathroom stuff.

I consider myself a pretty strong writer, as well as a talented artist so I would be more than happy to produce sketches based on the RP!

I'm also fine doing non-cannon sex scenes if you're horned up ;D

Without further adieu, here are my prompts:

An unwilling apprentice... (Magic based, Human x Monster, Lots of flexibility)

I was desperate, what can I say. Nobody would hire me and even if I was it would always end the same. Being down to my last few dollars, and facing the down the barrel of having to spend my nights on the street, I made a deal. He was sleazy, yes, the man I met at the bar. However through some connections I had made over the years I knew that as morally unscrupulous as he was, I could trust him.

The deal was simple, I needed to sell myself. Not in a sexual way, or as a slave, but to be sold off at auction and kept as a trophy due to my rather unique nature.

When you saw me come on the stage that day, in a dark room filled with smoke and painted masks, your arcane eyes immediately sized upon mine. You knew that I was special, moreso than anyone else in that room. However much you paid for me, I didn't know, but in the end I was yours. Unlike the others in the room however, you weren't exactly human yourself, and when I was first presented to you the naked look of fear on my face was plain.

Yet you would make use of me, in one way or another.

A different kind of covenant... (Halo, Human x Alien, Can be as non cannon as you want)

You were once proud, running your ship with an iron fist and executing all orders in good faith. Your dignitas knew no bounds, having claimed the mantle of Admiral, and being one of if not the most successful naval commanders the covenant had ever known. Yet while you were no fundamentalist, when the truth had been revealed to you, and the great journey was revealed to have been a deception you couldn't stand idly by. That's why you left.

You never particularly liked humans, in fact you had spent many a year decimating their ships in combat. However you had to throw yourself at their mercy, and provide what you could to stop the prophets from enacting their fruitless plans. Now, stripped of your rank and office, you've been reduced to being the ward of a young naval intelligence officer, whom must not only keep an eye on you but mine you for knowledge as well. How could you possibly adjust to a life such as this?
