The older brother looks like the main characters older brother from Asanaga Fuugetsu, Shodouka Desu. It is the same writer so It could be. The seme is totally a sadist that glare was not normal.
It ended without actually ending. Atleast the angle was chosen in the end. Inreally felt bad for him. You dont hurt the one you love like grain did T_T
Is it just me or is his short tail super CUTE? This brother is also super cute like shingo when he is not anal.
the short tail reminds me on a bobcat.I love how ei worships every inch of jins body.
