living with his brother meant that they shared a lot of things. they shared the bathroom, the living room, the kitchen──and, unfortunately, they also shared a bedroom. obviously, as two separate people, there were times when the two of them needed to not be in the presence of each other. they would never shower together, so they couldn’t be expected to always have to hang around each other, either. natsu never had a problem with spending time with his brother, but he did always do his best to give the other male the space he needed.
by that token, the male figured that spending all day away from his brother had been enough space for the two of them. thinking back, it was definitely a bad idea to walk into their room without knocking first, especially if the door was close… but he hadn’t been thinking, apparently. not at all. the door was shoved open and he was just about to ask what his twin had been up to all day when eyes were met with the sight of his brother… having some alone time. it probably shouldn’t have been unexpected─after all, they were twins─but it had been the absolute last thing on his mind. now it was the only thing.
coughing awkwardly and loudly, the twin spun immediately so that he was facing away from the other and looking out the door. it’s not as if the twins had never seen each other naked before (uh, they were twins? they always saw each other naked… technically.) but this was a new experience. they were usually really careful about this kind of stuff. but that didn’t make it any less disgusting. he never wanted to see his brother in that way.
⊰ 火の玉 ⊱ “W-What? A-A-And you know this be-because?” as you can see, Natsu became rather flustered from his brother’s words despite it not being the first time he had said something along those lines.
