Sempiternal. (слэш)

The council sent alphas to Gaara's room when he was in heat. Some smelled okay, some scents were rather neutral and some men he never wanted to see again. They were either too rough, brutish or crass, but he doesn’t get to choose them. The elders did. They always have.
Gaara wonders where they even get these alphas from, and why there are always so many. He asks before one of his heats, seated on the bed of his nesting chambers. The elder simply looks at him and answers, though it’s not what Gaara expects her to tell him.
Apparently a lot of alphas want to bed the Kazekage. They volunteer.
