Prometheus made a very small noise, low and rumbling, when Hades offered him that teasing peek, lifting his head as he started to very quietly pant. His feelers flicked up, to offer him more clarity - the swirl of aether around Hades and the sultry, mischievous thrum of his soul. He very much wanted to touch, and he leaned in slightly, his heavy breathing stirring the thin silk barely keeping Hades's decent and making it flutter.

He was beginning to recognise that clenching feeling low in his belly, taut muscles clenching and relaxing as they slowly forced out his cock from its sheath inch by inch. Not quite as amazing as Hades's, it still made an impressive sight, thick and slightly curved, rippling from near black to dark purple at the tip. Prometheus had to shift slightly, lifting his hindleg so it wasn't resting directly on top of it, his hindquarters leaning more to the side.
