This is more netorare than cheating.
Also, this is barely cheating, since the guy is literally blackmailing the housewife to have sex, who he slowly mindbroke with his dick.
Coerced consent (blackmail netorare) is not the same as real consent (cheating netorare).

The basic premise is the kind of the same archetype as (C93) [Shinjugai (Takeda Hiromitsu)] Himawari wa Yoru ni Saku, where a guy forces a woman to have sex with them, then slowly corrupts them to love his dick.
The only way this can become cheating was if this story continued after the initial blackmail day-long sex with the guy destroying the "proof" he used to blackmail the wife, or, promised never to blackmail the wife ever again, and the wife, on her own volition, went to have sex with him afterwards. From the text, it seems that the guy was still working her over until the husband arrived, and at that day, she completely broke.

This story finished before the hard netorare bad end for the husband occurred though.
