Natsuo's a bit disappointed when Dabi pulls him off, especially since he could feel the other man getting close in the coiled tension building in his muscles, but he's got a good point. It seems like Natsuo's in danger of becoming addicted to everything they do together so it's good that one of them has the self-control to progress the situation rather than just give in.

Wiping off his wet mouth and chin with the back of an arm, Natsuo sits up and looks into his brother's eyes - his own are fogged with lust, pupils blown so wide that the grey of his irises is barely visible, and his lips are obscenely swollen and red against pale skin. This is what Dabi missed out on the first time, and what he'll always get to see from now on.

"Yours," Natsuo rasps out, his throat obviously rubbed quite raw. "All yours. Always." He tugs Dabi's pants down to his ankles, then his underwear, so he can kick off the entire works. Once he's back up straddling Dabi's haunches, he gives him another deep kiss and whispers against his lips: "Only yours."
