Summary: Castiel has used Real Alpha since he was old enough to afford it. They’re a reputable company, and have never disappointed: every few months, Castiel calls in to an automated system to make his request, and within hours, there’s an alpha knocking on his door to fuck the heat out of him. He doesn’t care who it is, what they look like, how much stamina they have, whether they are angels or humans. It’s just an ends to a mean.
Until.
Comments: 9/10. Fluffy and smutty and awesome. Dean works for Real Alpha, which provides Alphas to knot Omegas in heat. Cas is an Omega angel who has had his wings cut off, he doesn’t do relationships but still finds himself attached to Dean.
