Note: this is my first post here. Right now it's just teasing, but for those of you who sympathize with the poor beast--don't worry, you won't have to wait too long; he won't be blueballed forever, and eventually gets revenge on his cruel mistress.
She has taken to calling it "the beast."
The creature resembles what she imagines a minotaur might look like... large, burly, with short, black fur, and a somewhat animalistic face... yet humanoid, as well. It has been imprisoned in their facility for some time, in a holding cell far removed from the rest of the complex.
Research has been proceeding well; much has been gained for science. Recently, she drew the short straw, so to speak, and has been elected to collect semen samples from the thing.
While he is otherwise free to spend time in his room, and has freedom of movement--before the semen collection procedure begins, the locks engage, and he is gradually brought to a working position: bound hand and foot against the wall, facing outwards, with his arms and legs spread.
At first, she proceeds in a rather matter-of-fact way; beginning by entering the chamber and snapping on a bright green rubber glove. She can already see the bulk of his genitalia out of the corner of her eye. They hang there, heavy and potent.
As he notices her, to her mild embarrassment, he grows semi-hard, his nakedness filling with life at the sign of the beautiful female. Even her conservative labcoat doesn't seem to hide her figure sufficiently to reduce his lust.
This is so humiliating...
she thinks. But she swallows her pride and--for the sake of science--she reaches out and takes his penis in her hand. He jolts at the sudden feeling, and she jolts back, intimidated by the creature's huge size. If it weren't for these gravlocks, he could easily maim or kill her. Even from down here below, the breath from his nostrils is hot and heavy, increasing in pressure and frequency when she handles his manhood. It's huge, along with a heavy ballsack--and, to the best of her memory, his genitals generally resemble those of a human male--although they also seem... equine, bovine? She can clearly distinguish the head of the penis. But she doesn't want to look at it too long. It's impossibly large and intimidating--and the longer she looks at it, the more she almost feels hypnotized by the obscene organ, the raw power of it. Her whole body begins to feel warm, beginning with her clitoris and nipples, then moving down to her vulva and through her breasts, until it's like her whole body is melting... but she shakes her head, turning away. The thing is practically an animal, it would be humiliating to be turned on by it.
What am I even supposed to do here?
