Cain's first word drew David's attention away from the room and back to him, and he became aware of how he was squeezing the mortal. His ensuant comments relaxed him as they should and his head eased back down onto the pillow as he loosened his grip and started to rub at Cain's arm and back instead. "Fuck, sorry," he said thickly, then cleared his throat in order to get the sleep out of it.
His brain was clogged with an uneasy day's sleep but he gradually recalled his night before with Cain, their resolve to spend time together, the sex and the shower just before dawn - whereupon the unsettled sleep began. At home, he didn't worry or really register subconsciously when Bill moved about during the day but he had with Cain, because he wasn't settled in the apartment to begin with. He felt irritated and surprisingly thirsty already. After a few more moments of getting his bearings, he spoke again.
"I know who you are," he admonished gruffly, leaning down to kiss whatever part of Cain's face he could get close to in his foggy state. The more he thought about the fact that Cain had just told him his name, in fact, the more amused he became and a smile curved his lips upward. "Silly," he added huskily.
