Slight NSFW.... enjoy

Zi Han bit his lower lip his lustful gaze trailing down Yi Chen's back before lingering on Yi Chen's butt as the warm water dripped down the two peaks like a waterfall.

Zi Han's hand slowly slid down and groped Yi Chen's ass which was slippery from the lather of the shampoo seeping down his body. Yi Chen's smile grew wider as he raised his arm to look at the hand taking advantage of him and said, "You aren't allowed to touch. This is private property so hands off."

Zi Han didn't let go. Instead, he squeezed it a couple more times while saying, "It's mine now. What's mine is mine, and what's yours is still mine," with a silly smile on his face.

With a loud resounding PA, Zi Han smacked him only for Yi Chen to turn around meaning to retaliate.

His revenge policy was simply two smacks for each smack Zi Han did. Zi Han tried to hide his ass but Yi Chen still managed to grab it a couple of times before slapping his ass cheek twice.
