84 Spank to spunk (Semi R-18)

Alpheus also had such a nice and perky butt, Cha Junshik couldn't help it and slapped Alphie's buttcheek.

PA!

"AH!" 

Cha Junshik saw how the wolf price was bending and pouted his butt, waiting for another smack, and he scoffed, "What are you doing? Do you want me to slap your butt again?"

Alpheus bit his lower lip, trying hard to hold himself from saying yes to Sir Junshik Hyung's question.

Because he wanted to be slapped again by Sir Junshik Hyung's strong and big hands. But Sir Junshik Hyung only looked down on him and said, "Do you want me to slap your butt again?"

…

"SAY IT, DOG!"

PA!

"Ahhh! Y—Yes, Sir, please slap my butt, Sir!" Alpheus finally released his voice after Sir Junshik Hyung slapped his butt for the second time. 

Cha Junshik saw how the butt jiggled when he slapped it. This dumb beefcake dog seriously had a nice body, and he probably didn't need to exercise to obtain such body, much to Junshik's envy.
