It had been a temptation to put his hands on Magnus' hips, but when he realized that his boyfriend was wearing just a towel, he kept his hands at his sides.  Swallowing hard, he tried to keep from reacting to how close Magnus was, keeping his breathing steady and not pulling him close so he'd know what Alec had been thinking about.  

 

"I'll make sure to get him treats to keep on his good side."  The words were accompanied by a nervous smile, sagging back against the wall as Magnus moved away.  He began to relax until he saw the towel fall away and realized that napping most likely would be done while naked.  

 

Or while Magnus was naked and Alec was...  He wasn't sure what he was supposed to do.  "Yeah."  Pausing, he hesitated slightly before continuing.  "Do you want me to get undressed?"
