Kaito notices the irritation, the way Sora wasn't hiding it as well, and categorizes it without a thought. There was no point in wondering what would happen if he missed and the leash snapped.

Jerking the collar again, Kaito tugs Sora toward him, until they're almost nose-to-nose, and grins in a way that shows his own edge. "You wanted this~" Then shoves hard, for the first time showing an effort, to force Sora down onto the bed. Kaito follows him in one smooth motion, so his finger never leaves the collar, and straddles Sora's hips.
