He's a beacon of temptation, his muscled frame tense with restraint. Their hands explore, tentative at first, then bolder, tracing the lines of their bodies.

They move together, their breaths coming in ragged gasps, until they shatter, their voices raised in ecstasy, mingling with the faint echoes of their father's distant prayers.
