"Ah!"
Tenma yelped at the sting of the riding crop. Johan's strikes were quick and severe—hard, bright smacks of pain that brought tears to Tenma's eyes. They had started out slowly, a little less forceful, but now they were coming one after another. He felt his ass quiver at each determined slap.
"You're so noisy, Kenzou," said Johan. "I'm not hurting you too much, am I?" Tenma could hear the smirk in his voice. He had stopped spanking him for a few moments, and was dragging the tip of the riding crop gently across the raw skin of Tenma's ass, twirling it in circles around the flushes of red. Some had begun to darken to a bruise.
Tenma could only pant in response. "Ah, your ass looks so lovely like that," Johan said, his voice a little more tender now. "I could just… mmm." He smacked him again, twice, in quick succession. Tenma whimpered.
Johan put the riding crop down on the bed and began to run his soft hands along Tenma's ass and parted thighs. The sensation was ticklish, and Tenma stifled a giggle, but not before Johan noticed.
Johan laughed, half devilishly, half warmly. "You are noisy, aren't you," he said. He spit on his hand and pressed one wet thumb against Tenma's asshole, massaging it in circles. Tenma gave a small, satisfied moan.
"Shhhh," Johan said. His voice was hushed now, almost a whisper. "No moaning until I tell you to. Now…." He slapped Tenma's ass, sharply and suddenly. Tenma shut his eyes and gritted his teeth. "Be good, and I'll give you something more."
He began rubbing Tenma's asshole again, harder now. Tenma knew what Johan wanted—what they both wanted—and he was eager for it, his body tensed and flushed with pleasure and exquisite pain.
