Half sheepishly, half embarrassed he pulled back and sat up and removed his hand from under Jamie's shirt. There was no way to make this look good, but at least he wasn't being thrown out. "Euh, hi." He offered a sheepish smile and cleared his throat, rather hoping the couch would suddenly eat him.
