Carrick was pleased at the slave's initial reaction to the first spanks. Although she gasped at the sensation, she did not flinch from him.
He repeated the two spanks, then moved his hand lower, to the underside of her buttocks, delivering a series of slow, hard spanks to each one in turn.
"Your Master wants you thoroughly punished," he said as he continued to spank her in a regular and measured rhythm. "And I'm going to oblige. It's not just going to be this lovely little white arse that's red and sore by the end of the night... though I'm hardly going to spare that particular area."
Carrick's spanks sped up and he began to cover more of Jenn's rear with stinging, decisive spanks, his hand sometimes cupped a little to create a louder, more powerful sound and reinforce the effect of her powerlessness as she lay over his lap, unable to resist.
When Jenn's ass was a warm, glowing pink all over he turned his attention to the backs of her thighs, and then the ultra-sensitive soft skin at the crease in the very base of her buttocks.
"Are you beginning to regret your behaviour now, slave?" he asked.
