Theo quietened as Greg left his shaking body alone in favour of covering him. He curled the towel in against his chest, pleased for the warmth, but he felt a little burst of prey-animal fear at the look Greg gave him, his panic stayed only by Greg's voice bringing him back to who this was and taking him out of the dark fairytales of his crazy.
He squeaked as Greg curled a familiar rough hand around his erection and he bucked and mewed helplessly like a kitten as Greg kissed and licked and sucked at him, his noises echoing in the bathroom but not loud because apart from the times where he became angry or afraid and shouted he had been newly quiet since coming out of St Mungo's.
His mind hadn't gone to those dark places that scared him so, hadn't flicked him into a confusion of routine at St Mungo's despite their surroundings and he wasn't back in his teenage years either, but seemed to just be running on autopilot, raw and taken over by pure sensation.
