Aside from that, as a hentai this was honestly so dumb. The plot is literally just "My not actual big bro is my big bro because we hung out for a bit when we were young and now we wanna smash all the time." Like hello? Bring back some dope plots like 'bible black' or 'color of the sky'. The series wasn't all bad though, the whole "i'm not gonna bust a fat one in this girl." is at least kind of makes sense because this dude is probably like 21 and doesn't want to get her preggos.
Anyways, I wrote this like half awake but that's my half assed review of this "anime".
