I Got Transported as Extra in an NTR Eroge Game

One night, Gilbert was mad after he got pranked by his friend to play an adult-themed NTR eroge game. He was so furious that he instantly cursed the bombing review of the game rating. He then went to sleep after draining his energy from going mad. However, when Gilbert woke up, he found himself inside the very game he hated yesterday, not as the MC or the Villain but as an Extra. Realizing this fate that befell him, Gilbert decided to channel his anger to all the disgusting characters inside this game.
