Bakura Ryou is a modest boy, too modest if you ask Seto's opinion. He's fairly bright really, it only took him two tries to get the cock ring adjusted to the right size, and he seems to know instinctively when to administer the shocks.
He keeps looking back at Seto though. "Am I doing it right?" he asks anxiously, and if all he does is nod in response, then he waits for an answer.
"The point here, Bakura," and he can feel himself growing impatient here, "is to keep going. You're trying to get a reaction, you think this starting and stopping is going to help?"
"I'm very sorry, Kaiba-san," and Bakura bows, just a little bit, as would be fitting toward an upperclassman, at least if they were at school, "I've never done this before." Humbly, "it doesn't come very naturally to me, I'm afraid."
Seto gives a very irritated sigh. "Why did you have to stop now?" He doesn't say 'I was just about to come', but that's what he's thinking.
"It's all right Seto-kun," from his position underneath Bakura on the floor, Mokuba pipes up. The ball-gag muffles his voice a little, but he's perfectly understandable, "I wasn't having very much fun anyway."
