Sigh. The 3 good things I can say about Otonari NTR is that (1) it’s no less than 145 pages long, (2) the female heroine is a hot redhead, and (3) it’s in full colour.
After, to me, it’s a wreckage, but you’re welcome to disagree.
I suppose I must summarize the wreckage nonetheless: a housewife is accidentally raped by her scumbag neighbour, he shamelessly proceeds to blackmail her in order to have more sex with her, day after day he comes back to her behind the oblivious husband’s back. And what had to happen, happens, the wife is won over by the scumbag’s superior technique and endurance, the husband is only a spouse in name in the end.
Sigh.
I don’t mind “evil” adultery, netori or netorare mangas, but at least it’s got to be well done, you know? This way, even if it’s a theme I don’t like, I can enjoy the talent with which it was brought… but, here… sigh. 
Anyway. If it suits your tastes, I have no issue with that, enjoy then!
