Hah. I can't decide if this one was better or worse than the first one...
I suppose that in terms of endings, it was better, in the sense that at least the true end for it actually has some proper finality to it. That and they actually had Mayumi come clean fully on her shenanigans. The "bonus bad ending" so to speak is kind of pointless on the other hand, in the sense that the hubby would have to be pants on head retarded to not acknowledge how much of the whole mess was his fault.
That said, in other aspects, this story was worse, what with the increasingly improbable number of people with increasingly improbably massive dicks that are capable of fucking Mayumi's brains out better than her husband. It's at the point where I believe that she simply gets off on cheating just as much as her husband gets off on being cheated on, and that makes her ridiculously sensitive to the point where anyone with a bit of skill can make her cum buckets.
Also, her turmoil over the incident "seven years ago-ish" is weird. After all, even if she was all over that one guy... she was also stupid drunk at the time. Being drunk lowers inhibitions pretty severely, and considering how weak she is to alcohol, she can't really be held all that responsible. Most people that get drunk do and/or say things that they never would otherwise while sober...
Also, the hell is with all these smokers supposedly being studs? It's like in the Atelier Sakura universe smoking doesn't destroy lungs and doesn't have all sorts of nasty side effects when it comes to stamina in general... No heavy smoker will ever be a chad destroyer of pussy, not for long, and not with how much the one supervisor dude smokes...
Eh... I suppose my hatred of smoking is rearing too much of its head right now...
