"Yeah," John manages, and he opens his eyes long enough to blearily check how much of a mess he's made. Satisfied it's not too bad, he tugs Ianto more comfortably into his arms -- settles himself holding onto the other man and lets out a satisfied sigh. "M'good," he manages, and rubs his face against Ianto's shoulder. "Stay."

Not that he thinks he's planning to leave, but... all the same. Ianto likes the reassurance, he knows, and John is content giving it to him.
