Not that Junior knew any of that for certain, but he was definitely rocking his hips and getting into the motion, breathing faster and rest of his body reacting. Just this was enough to catch his focus and he was going to keep going with it, hand twisting lightly in Ash's hair to hold him still while Junior pressed further along with what Ash was already doing, in and out to see how Ash would react and how much he could take.

Still, as with anything else, there was a certain amount of gentleness to it. Not necessarily holding himself back, but like he just didn't want to go too far no matter what.
