Oh, it's very much a challenge. One that has Seifer almost snarling at Squall because how dare he question that. The blonde adjusts his grip and prepares to move them only... Fuck, when had Squall learned such good distraction tactics? A kiss like that, just on the edge of too dirty to think about, is enough to get past his initial guard.

So he retaliates in the only way he can think to do. Which is to shift them so part of Squall's weight rests on the counter. That frees up his hand just enough to pull back for a light slap to Squall's thigh.

An unspoken way of saying 'behave'.
