Chapter Text
He’s honestly ecstatic with the new realization that you were immune to his flames. That they didn’t burn against your soft and supple flesh and that he could relax.
The way he actually found out was by complete mistake not to mention scary. (Because if it would have went the complete opposite direction, he probably wouldn’t forgive himself…)
You could say he had gotten a bit…reckless the one time he was plowing into the warmth of your cunt. So tight, so hot around his cock, you were squeezing him so much so, it was hard for him to actually get his strokes in. Your moans had been music to his ears, especially when the occasional, sexually charged ‘Dabi’ would roll from your tongue. The grip on your hips were bruising as held on tight as his hips slammed repeatedly against your ass.
By each passing second, he was growing hotter as he grew closer to his nut. And by hotter, the palms of his hands and body rose in temperature in a much different way than if he was merely sweating from over-exertion. The barely visible flickers of blue that had danced along your skin didn’t register to him at first, his foggy mind reeling from how good your pussy felt wrapped around his cock and how good he was reckoning his nut was about to be.
It was only until the blue glints arose in intensity that he cursed beneath his breath, trying to get control of it. But when he looked down, he was surprised to see that your skin was still intact, where his hands were placed. And that you weren’t screaming in absolute agony… It was strange, his Quirk not burning you.
He questioned you about it moments after the two of collapsed in sweaty and fatigued forms, entangled within one another. You were confused right away when he told you his Quirk activated, responding with the fact that all you felt was the heat of his hand. That it wasn’t painful much like the burn that was expected with his Cremation.
His mind was boggled after that incident but it didn’t stop him from testing it once more to see if this form of immunity could actually…be. After much ‘experimentation’ which resulted in the same thing, he grew to accept that there was finally someone who wasn’t hurt by his destructive Quirk. While that made him appreciative enough on its own in a way that made him worry less about mistakenly burning you, he was also excited to be able use this to his advantage in the bedroom.
Especially since you expressed that you didn’t have an issue with it, that it was actually hot…
After seeing you become used to his hesitant Quirk activation during sex, Dabi wanted to do more with this. He controlled the intensity of his flames against your skin, finding that the hotter he went, the more you felt the heat and the more you expressed how good it felt to you.
The heated sting when the palm of his hand slapped your ass, the subtle heat when he’s carefully rubbing tight circles against your clit with the tips of his fingers. It even seemed his cock was a little warmer pressed against the velvety walls of your cunt. He loved using his heat to tease you, loving the way you squirmed as the tips of his flames licked against your skin.
Ultimately, you being immune to his fiery Quirk was one of the best things he loved about you.
I’m so not going to ignore you because this is interesting as fuck and I haven’t seen it before either 🥵 so thank you this!
