The kiss is good - he's trying not to think of how long he's wanted this, doesn't want to get swept up with questioning how he feels - but Toshi realizes that maybe he's moving too fast for Souji. There's plenty to do and appreciate already. One hand comes away from Souji's back, and gently catches one of the other man's wrists. He brings it up, and presses a careful kiss to the pale skin, marred only by a fine, faded scar.
