Gabriel was straddling his brother, both of them naked. His wings were out, a golden-brown canopy above them. The little archangel was grinding his ass into Castiel's groin while pressing kisses and nips to the sensitive flesh of his neck. The darker angel groaned, growing desperate to be inside the other. Flutter. Gabriel's eyes widened as he heard it. Flutter. "Cassie, please, let your wings out." Flutter. Castiel flushed, fighting a losing battle. I-I've never shown my wings before... "Please?" Gulping, Castiel let them out. Ice blue wings, darkening at their tips and covering the shades in his eyes. Breathtaking.
