Everyone else burst into laughter, then one of them leaned toward me and explained, “Sabrina, don’t take it the wrong way. Barbara’s been like one of the guys since we were kids. She's always hanging out in the bathhouse with us, joking around. Friends know each other’s bodies inside out. Totally normal.”

Normal? I’d heard this same excuse too many times, and I was already sick of it.

Again, a wave of disgust and humiliation swelled inside me.

Without thinking, I grabbed the dirty diaper in my hand and slapped it right across Barbara’s face.

By the time she realized what had happened, her face and lips were smeared with fresh yellow stains.

She shrieked and bolted for the bathroom, while Phyll yanked me hard by the arm.

“Sabrina! What the hell’s gotten into you?!”

He shot me a vicious glare before rushing after her.

Yet I just shrugged and gave a mocking smile.

“What? Brothers know each other’s bodies, right? Then surely, being familiar with his son’s diaper smell is even more natural. Don’t you agree?”

After that, the room fell silent, and none of them dared to answer.

I then glanced toward the bathroom, and a heaviness pressed against my chest.
