Theo's humming hitched as Greg pressed in deeper, and when it came back it was a little more strained like the boy was desperately trying to drown another sound out, on the verge of whimpering. He shivered as Greg's touches became less medicinal, but he didn't try to fight, although his humming lapsed into silence.
He murmured and shifted as Greg fingered him, the cream making him numb inside but the action making his cock make an attempt at getting hard, although the psychological boundaries it was coming up against were working against it. Theo looked back at Greg but didn't really seem to see him. "I'll be a good boy." he murmured. "Won't tell anyone. Seen not heard, seen not heard, won't say a word, promise promise promise."
