The Program (гет)

Alphas and Omegas depend on each other for relief from their designation. The longer that they deny their bodies' needs the worse the symptoms become. An Omega's heats will only get worse and more frequent, while an Alpha loses his control completely and is launched into a rut which affects not only his body but his mind.
The Ministry launches a program to help deal with the Alpha/Omega problem in the Wizarding World. They offer the chance for relief without admitting to your designation. A matching system where an Omega can use an Alpha to see her through her heat and an Alpha can use an Omega to keep his sanity. The best part is it is completely anonymous, the matches are decided based on mutual attraction to each other's pheromones, and a potion prohibits the brain from recognising your partner.
Hermione Granger has never been with an Alpha, her heats are becoming unbearable. Draco Malfoy begins to lose control of his body in his fight against his own designation. Ultimately they surrender to the program, knowing they have to face the inevitable lest they lose their own or take someone else's right to consent.
