Dean gave a contented little hum as he managed to curl himself around the dream version of Seamus, feeling lazy and content, caught up in a dream or fantasy where they were together and he could do this whenever he wanted. As his body began to wake a little more so did his cock, beginning to fill slightly.
Of course seconds later his ridiculous fantasy went a way that real life certainly wouldn't allow and Seamus' sharp voice jerked him awake with a start, his whole body jerking with the shock. It took a second or two for his brain to catch up with reality, in which time his body was already moving, jerking away from Seamus, and then actually scrambling backwards, accidentally kicking Seamus in the legs as shifted backwards, his face had transformed into a picture of horrified realisation that the 'dream' he'd been having probably hadn't been dream at all. "Shit!" he said, voice rough with sleep, racked with horror and guilt that was just beginning to creep into his stomach.
"Sorry. Sorry," he said, breathing hard, now as far as possible from Seamus while still being on the bed, nearly teetering on the edge. He couldn't say anything else, just shaking his head in slightly wide eyed horror. He hadn't quite realised yet that his breathing was starting to have a slightly panicked edge to it.
