Ultimatum (1)

Arren laughed as Spade lifted him up and placed him on his shoulders as though he were a heavy sack, before starting to leave the study in that position. He was on his stomach as his buttocks faced Spade, with his head facing the alpha's back.

His laughter became louder when Spade even slapped his ass—not too hard, but the sound of the flesh being hit sounded. 

He laughed and wriggled. "Spade!" he exclaimed, "Did you just slap my ass? What's with you?" Arren only asked this to emphasize the action while also enjoying it at the same time. 

Spade could only shake his head, biting his lips, and control himself. He could never resist Arren, even if he wanted to. Tightening his hold on Arren's body so he wouldn't fall from wriggling too much and slapping that ass once more, he helplessly sighed.

"Don't make trouble," he darkly warned, yet the fond exasperation in his tone was too clear to ignore.
