MamaRPG ～Creampie to mom who became NPC～

When I woke up one day, Yota was in the world of common RPG.
Ignoring the confused Yota, Yota’s mom talks to him.
As an NPC who doesn’t have his own will…
In such a world, Yota will be forcibly ordered to exterminate the Devil.
However, Yota forcibly takes the NPC’s mom to an adventure and robs the erotic clothes worn by the female monsters.
And Yota puts the erotic clothes on his mom and does a lot of naughty acts.
Even if the monster is a middle boss or a devil…
And finally, after defeating the Devil, Yota learns a certain truth.
What kind of action will Yota take at that time?
