Kisses on your arms, left little red marks for hours.

Kisses on you chest, left bubbles that lasted for days.

Kisses on your neck, left blisters for months.

Natsu's lips were hot, and his saliva was scalding. You could barely stand the heat on your body.

But it wasn't like you had much choice, anyway.

~~~

When you first met him, you had worshipped him. You wanted to become as powerful of a mage as the dragon slayer.

And he made you a deal.

If you helped him through his upcoming heat, he would train you. You didn't care about your virginity. It was just a social construct put on women to evaluate a price for them.

The first heat wasn't the worst. It was always the heat after that. The ones where your scars and blisters from the previous time stung against your skin.

~~~

He was particularly cruel to you that night. His nails were digging harder into your hips. You could feel his pulse was higher than usual.

"Don't fucking leave...." Natsu said softly. "Don't leave me...."

You looked up at him when he stopped, you cupped your hands against his face and whispered, "I won't, I promise you...."

"If you do, I'll chain you up....." He kissed your neck, leaving yet another blister for you to heal later. "And break you...."

~~~

A month later, that's just what he did.

You forgot what sunlight looked like for about another three weeks, but the little bit of heat you managed to put onto those thick cuffs freed you from them. Too much heat alerted Natsu, and then he'd beat you into submission.

Now you were free, and you ran away.

Faster and faster, because everytime you stopped and looked behind you, you saw fire in the distance.

And the earth scorched and the trees blistered.

You could only run.
