Every noise pushed Chris on-He didn't make noises like that, did he? He was pathetic. When Stabler pulled away, Chris' eyes fluttered open as he stared at the man for a moment before heading up the stairs after him, holding the rail to keep himself steady, waiting to be at the top before again pushing Stabler up against the wall, needing to get rid of his energy, to try and calm down, spend himself, so he could go home to Toby.
And that thought made him make a frustrated noise, to think he was doing anything for that man after he betrayed Chris again, Chris would again go back to him. But Toby was who he loved. Even if he was a slut. Chris leaned into the kiss hard, lips mashing into Stabler's with little thought or effort to not hurt the other man (or himself) as Chris grabbed Stabler's hips and pulled him forward to grind their hips together.
