To me seems that something is missing... I liked the manga, but the end was a little bit incomplete (?). What about the situation between the twins? They have sex with big brother but don't have any romantic feelings each other like if their likes are just like brothers, isn't it? ┑( ̄Д  ̄)┍
Actually, one of the twins seem to have been developing feelings towards the other too, and they were really close to have an actual menage, not just two guys sharing a bottom. I think that on the next few chapters one of the twins is going to bottom for the other
I'm here reading again and waiting for more ╮( ̄▽ ̄)╭
Its not completed yet?
