Yes, somewhat

One of your rescuers whispers something to the elder, and then the leader speaks to you and Calyra.

“My hunters say they rescued you from goblins. But also that the goblins had their way with one of you. Based on your appearances, I guess that is you.” He looks at Calyra. The clues are obvious. She is still barely dressed, her large breasts not at all contained by her ripped dress. Even the bottom of her dress is torn, and she is trying to protect her modesty by holding a hand over her pussy, which would otherwise be visible. The goblin semen is dried out by now and no longer stains her legs. At the mention of her disgrace, she starts to silently sob.

“This next part is very important. Do not lie to me!” The elder centaur’s voice has a serious tone to it. “Did the goblins come inside you?”

At the mention of this defilement, Calyra’s sobs grow in strength, and she is barely able to whisper a ‘yes’. In fact, you must repeat it for her.

When he hears this, the centaur leader looks at the one who brought you in. “Prepare her!”

Before you can question what that means, Calyra is taken to the pillory you noted on arrival. The centaurs tie her down, so her body forms an inverted V. Her arms and legs are tied to pegs at ground level, her ass raised on a wooden frame. Even worse, her legs are tied so that they’re spread. The centaurs rip the dress from her body. In this position, she is completely exposed. Her ass and cunt are very visible, her large breasts dangling unsupported beneath her. You cannot look away, and note that her pubic hair is well-trimmed, forming a soft triangle above her slit.

Calyra tries to speak, and one of the centaurs force a piece of cloth between her teeth, silencing her.

The leader looks back at you.

“This is not what it looks like. In fact, we are trying to save her. Goblin sperm is very dangerous to humans. It has a high chance of impregnation, and the hybrid offspring would be a very dangerous pregnancy.” You try to protest, but your attempt at explaining the healing magic of Hogwarts are cut short.

“There’s no time to bring her to your healers. And there’s very little they could do, even it they were here. Our only chance is to flush it out.”

You look around the gathered centaurs. It seems Calyra’s exposed position has had the expected result on them, and between their horse hindlegs most of them are by now sporting very visible erections. You swallow as you realize they are all literately hung like horses.

Suddenly, the strange pillory and Calyra’s position makes sense. The way she is tied allow the centaurs to breed her!

The elders keeps talking, ignoring the desperate and muffled cries from Calyra.

“Our physiology does not allow us to masturbate like human males. We will require more direct means of stimulation to fullfill the task at hand. That is, unless you want to help us out?”
