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!

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

The feeling of having a wet mouth devouring his dick was marvelous, making Damian moan in a deep voice, "you are quite eager for this."

She gagged on the cock, stopping for a moment to say, "I needed this. Please, take me with you after this."

"Let's see how you do in bed first."

Wendy had a fire burning within her, and put even more work on sucking the cock, grabbing it with her hand, and putting all the way inside her throat.

Damian was loving it, and she was not letting him down, showing a decent amount of expertise with the cock sucking aspect.

She placed her boobs around the cock, rubbing it with her soft breasts, while licking the mushroom head.

Damian loved every second, and his manhood got harder and harder till the point he could not wait to fuck her holes.

"Cum inside my mouth first, please. I want this," Wendy said.
