The day dungeons appeared on Earth, everything changed! From ordinary beasts to monstrous ones, attacks were common throughout the globe, and no one was safe.

After countless studies using these beasts as subjects, Humankind developed a serum capable of awakening incredible abilities in humans, leveling the battlefield.

With the serum came heroes and villains, those who wished to use their powers for good or bad.

The Garmony Upper School was a place for the elite with the sole purpose of creating heroes to fight the villains and explore more of the dungeons after the beast attacks increased for no apparent reason.

Damian Romero, a youth who received the serum after turning 18, yet got no unique ability. It was not uncommon for one to not receive power, but it was still a blow to one's pride.

He went rogue after the news, drinking alcohol and having a good time with women, and it was at that moment, when he was putting his toy to play, he got a surprise.

Damian's unique ability was a system with multiple functionalities, but after he studied it, it seemed this system worked with a different type of coin called Erotic Coins!

Improve his body? Buy any item or unique ability from his system's store? All Damian needed was Erotic Coins, and he knew how to earn them!

The MC will not start as a villain, but something will shift his mind in the future.

All-in-One System: All I Need is Erotic Coins

Luna had gorgeous breasts. They not only looked perfectly rounded and big, but soft and warm too. She used them to rub Damian's cock, and the feeling was overwhelmingly good.

"Am I doing this right, Damian?" Luna asked as she used her breasts to rub the cock while smiling in a sexy way to him.

"Yes," Damian said, moving his hand forward to squeeze her breasts, "It feels good."

That was the farthest they went that night. Well, Damian licked her pussy too and used his fingers, and cummed on her face and breasts at the end of their night, but no penetration happened.

The place they were in was silent during the night, and the tents were too close to each other. It wouldn't work, so Damian decided to avoid it. But still, the night had been great, and Luna also enjoyed every moment.
