Hey there! I'm 26, trans masc sub who's always a good boy. I'm so much of a good boy that people find it hard to be cruel to me since I just take it. I want you to be the sadist to take advantage of that. I have lots of kinks including darker ones like gore, snuff, even beast. Limits are pregnancy/breeding, scat, and underage. Non negotiable.

Ideas:

For the public: I think we're just going to the market (or zoo or alien bar, etc), but you're donating me for free use. You coach me through taking all kinds of cocks and abuse, telling me I'm a good boy and this is what I deserve. I try to take more and more extreme treatments just to please you. By the end I'm a soiled disgusting cum dump, not an inch unmauled. Maybe you'll take me home and take care of me. Maybe I'm forever treated as subhuman after this, but that's what whores who lick monster genitals deserve. For a darker but optional ending: Maybe you'll rape me one last time, piss on me, and kill me, leaving my body for the dogs to hump and eat.

Surprise service: This is the cliche where I volunteer to help with a cause. I want to help the animals or help with experiments, and I'm turned into the animal or their sexual relief. Hucow fits into this (lactation okay, pregnancy is not), body mods and alien experiments fit into this, even being a diplomat for foreign powers-turned onahole works. I could also somehow get roped into being in a brothel. But you insist that this is for the best and I'm helping the cause, so I take it. I'm open to transformation into a different species or into an actual sex toy.

Moulded for you: Maybe you start by groping me in public but because I didn't say no, you said I wanted it. I got wet and moaned when you raped me in my sleep, so I wanted it. Of course I wanted you, I forgot to lock the door. Of course I deserve the shock collar, it helps me speak to you better. Of course I want the bitch suit/body mod, think how happy life will be to exist only for your pleasure... This could also involve having people or creatures have sex with me that I would hate, but since it was a gloryhole, or drugged, or blindfolded I didn't know. However, I orgasmed so that makes me a disgusting slut who needs your guidance.
