Reading from getchu, it's been five years since marriage, they moved to a new apartment, wife is finally pregnant, but from an acquaintance the MC acquires a porn that seems to star his wife!?
The other woman is a neighbor who is the old guy's mistress (both from previous NTR games, old guy is a yakuza + AV actor). The title says "your child was aborted" so I assume she was raped in the pregnancy celebration party which is mentioned and was subsequently blackmailed.
The bitch aborts her husband child 3 months into pregnancy so she can have that old pornstar dude's baby instead. Despite him completely ruining her career, marriage, and life... Das some fucked up shit... ngl. I was visibly shocked that she actually did that at the end.. and I've read alot of NTR over the years.. but damn is this redhead one cock'd brain cumslut.. goddamn smh.
