Unexpected side effect

A few days went by. Nothing really major happened during that time. Your bunny-boy, who was named Doe, kept his distance from you but was too afraid to leave your laboratory. He had been able to find some rags and stitched them together to make some primitive clothing. It was just a loincloth, but it covered what needed to be covered.

You could easily leave him alone when you left your lab, but to be sure, you still kept some guards near the exit.

Whenever you came back he was always quick to jump up and hide somewhere. You presumed it was the bunny aspect, the instinct of a prey, that made him act weary to you.

But over time he steadily became used to your presence. Eventually he got bold enough to come near you.

Today was one such a day. You were reading up on a thesis from one of your colleagues when he spoke out.

"What are you doing?"

"I am reading a theory on the relation between the different elements. Like, the different ways a nexus can be formed and manipulated."

"Ah..." He replied. "That sounds interesting."

"Oh, it is. Nexi are power conduits. They can be incredibly useful for large spells."

Doe stood behind you and put a hand on your shoulder.

"Have you ever used a nexus before?"

"Oh yeah, couple of times." You told him. "Usually for battles in the last war. I had the enemy army's lured to where those nexi were, then I used it's powers to conjure massive spells."

"You must be an incredibly strong sorceress."

You turned to look at him and stated "The strongest in this nation."

You stood up from your chair and turned to face Doe.

"You know, there's something about you that has been bothering me."

Doe's ears straightened up, a sign he panicked.

"Really?" He replied hesitantly. "Why ... why would you think that?"

"You don't usually get this close to me. You always make sure to keep a certain distance. But as of late you've been breaking your own habits and keep getting nearer to me. Why is that?"

Doe became nervous now. It was like he hadn't realized his actions himself.

"Well, that is ... I, uhm ?"

He put a hand on your arm and continued to explain himself.

"I have been ... thinking ... and well ... it's not easy to ?"

His breathing became heavy. He stared into your eyes and it felt like he lost himself in your presence.

"Whenever you are near ... i don't know ... I've never felt this before ... I don't understand ... I have to ?"

his body was leaning against yours and his hips were unconsciously moving back and forth. You suddenly got an idea what might be going on. Was he going into heat?

He suddenly wrapped his arms around you and started humping you.

"Ooooh, I am sorry. Mmmh, I can't help it, ooh gods, I need that. Please, please let me have this."

You knew bunny's were infamous for their mating, but wow, you never expected this.

His bunny instinct must have caused his hormones to skyrocket and make him want to breed with whichever female he came across. Since you are the only one here, it was only a matter of time until he was drawn to you.

Doe moaned loudly while he humped your bones. It seemed like all his inhibitions had fallen away and now he had been reduced to nothing but a crazy fuck-bunny.

You thought that maybe you could take advantage out of this. Strip down and have him pleasure you. If he really was in heat, he ought to be able to keep it up for quite a bit.

But then a thought hit your mind. What if he were to knock you up.

It would make it difficult for you to continue your experiments. Would the child be human like you, or a half bunny hybrid like him?

Would it be worth it?
