Happy ending and the son even wants a second child lol.

Also believe it or not, the police actually did do something (albeit too late lol).

[Synopsis]

Five days have passed since he was locked in the "room where you can't get out unless you have sex."
That morning, there were adult toys and cosplay costumes in the entrance hall.
They must have been put there by the people who locked them in.
However, there was the cow-print bikini that Kazuki had imagined his mother wearing and had masturbated to countless times...
His mother blushed in embarrassment as she put it on and Kazuki couldn't hide his excitement.
From there, the two of them continued to mingle.
Gradually, the acts escalated with bondage play, electric vibrator torture... and even anal play...
At first, the mother was conflicted but before long she lost her inhibitions and became wild in front of her son's huge cock.
Will they be able to get out of the room after having sex 100 times?
And what will become of this forbidden relationship between parent and child?
This is the grand conclusion to this forbidden mother-son incest work!
