Caleb's Rut [LaDS BL NSFW | Fanart] (Patreon)

Rut is the overwhelming need to breed. Alphas generally go into rut every three months, though with a bonded Omega mate, their ruts may align with their Omega partner's heats. Ruts tend to make Alphas more aggressive toward any other Alphas who might come near their Omega/bond-mate.
