I Became a Scoundrel of a Chaebol Family

The experimental drug administered alongside the pleasure-enhancing one was commonly referred to as the "cheat drug."

The reason for its name was simple. It had minimal side effects but an absurdly high addictive potential.

Once someone used it, quitting was virtually impossible. And with its low side effect profile, the survival rate among users was remarkably high.

This meant that, compared to other drugs, a single addict would consume far greater quantities over their lifetime.

Combined with its already high production cost and the excessive quantities required, it had earned the title of "cheat drug."

If not for Grandfather, I would never have considered selling it to someone like Jang Kyung-soo.

Well, that ship has sailed now.

For the time being, I’ll rely on the points I’ve accumulated so far and carefully handle its development and distribution.

Anyway, Yeon-ju didn’t just experience the cheat drug on its own—she was under the influence of the pleasure-enhancing drug at the same time.

And while that was happening, my dick was buried inside her.

Chances are... she’ll never be able to return to a normal life again.

During the entire time she was violated, under the influence of both drugs, she convulsed, moaned, twisted her body uncontrollably, and climaxed repeatedly like she was pissing herself, until she passed out, utterly exhausted, on the verge of collapse.
