This is pretty much NTR. The set up, her piss poor excuses, her lack of rationality, and to top it off her lack of any self control because the sex is just to good. Art was great but the characters? Yikes.
"I had quite a bit to drink, so it may have loosened me up a bit" lmao...Naw, she saw that dude's shlong and the inner-slut from yesteryear was released.
'Class Reunion', eh? The way hentai is, almost makes you never want to let your wife ever go to one.
And oh, how ironic for the husband to say 'she's having fun with an old friend'. If only you knew, my friend. I feel kind of bad for the guy, he seems like the understanding, nice guy sort of person.
That ending though. 'I feel bad for my family, but I can't stop now'? Well, at least you feel bad, but that's small comfort for your poor husband.
I don't like it if the woman has been forced to do but if she willingly to do this then I don't have any problem, in fact I like it. Yunioshi sensei are really good at drawing a sexy mature woman. I'm fine with both Vanilla and Cheating as long as the woman happy with it.
Seriously though. Class reunions remind me of whatever the fuck F4U did. that chapter was this but without all the "character", Which, Ironically, made it better.
Better sex, really sounds like a piss poor execuse to cheat or to even fuck someone. Man I want the guy to find out. it will be sad, but he deserves better.
I think cheating is far above NTR. Maybe not all NTR has it, but all the stuff I have seen usually involves alot of rape (either through drugs/alchohol/etc.).
And with cheating, I can always hope the person being cheated on, is in fact cheating as well, to balance out. That doesn't really work with NTR...
